    Description Dental devices for examining the dentition or for measuring the tooth pocket depths or interdental spaces are known in various designs.
    The dental probing instruments are often made of metal and mostly stiff.
    From US 4 959 014, for example, a probing device for measuring the distances between the teeth is known, which is used when carrying out tooth position corrections. For this purpose, the known probing device has a plurality of cylindrical sections with different diameters.
    Furthermore, a device for measuring the depth of the periodontal pocket is known from US Pat. No. 5,178,537. The probe tip is provided with colored rings to enable the depth of the pocket to be read. The probe tip is designed as a disposable product that can be inserted into a holder of a handle.
    However, so-called flexible plastic probes are also known. According to DE 19 913 544 A1 or EP 0 318 553 B1, the flexibility or flexibility serves to reduce the risk of injury (atraumathicity: DE 19 913 544 A1). EP 0 318 553 (Loewenthal) strives for sufficient flexibility of the probe with a certain area for the flexural modulus so that it cannot stab the user in the gums.
    [0006] The cleaning of interdental spaces is an essential part of effective dental care. Interdental brushes or interdental brushes have been developed as an alternative to dental floss. Typically, the interdental brushes have two fine, twisted wire pieces between which bristles projecting radially outwards are clamped. The fine wire element can be easily inserted into the interdental spaces, the teeth being cleaned by the radial bristles. Because the approximal distances can be very different, different brushes are provided. For effective dental care, it is now of central importance that the size of the interdental brush used is optimally adapted to the approximal distances.
    To determine the optimal size of the interdental brush, so-called probes or probes with predetermined parameters are inserted into the interdental space. The approximal movement of the interdental space in question is determined here by the probing section and its parameter that can just just be passed through the interdental space.
    The document EP 0 892 625 B1 discloses a device set with a number of different interdental brush types and at least one probing device with a plurality of flexible probing elements with different parameters for measuring the approximal movement of the interdental spaces. The probing elements are matched with the different parameters to the different types of interdental brushes, so that the correct interdental brush can be determined directly by inserting the probing device into an interdental space.
    The dental devices known in the prior art are still unsatisfactory, be it because they are too uncomfortable to use or lack of durability or reusability.
    DESCRIPTION OF THE INVENTION The object of the invention is to create a dental device for probing interdental spaces which belongs to the technical field mentioned at the outset and which is suitable for being adapted to the different needs of the users.
    This object is basically achieved with the features of claim 1.
    In particular, the user should be able to shape the probe himself to ensure the conditions for user-friendly use even in hard-to-reach places in the dentition.
    It is a further object of the invention to provide a device set with a dental device in accordance with the above-mentioned object.
    [0014] According to a first particular aspect of the invention, the solution is defined by the features of claim 2. The essence is that the specific combination of three different parameter ranges defines a plastic that enables the desired properties of the probe. The focus is on the suitability of the probe for determining the optimal interdental brush. However, it is not excluded that these properties are also advantageous in other applications. The combination of parameters according to the invention are:
    a) Flexural Strength according to ASTM D790-03 from 30 to 300 MPa,
    b) elongation at break according to ASTM D638-99 of in particular at least 10%, and
    c) Flexural modulus according to ASTM D790-03 of at least 1 and at most 15 GPa.
    The determination of the material parameters are based on the ASTM standards mentioned, which came into force on 01.01.2018.
    In the combination (and in the application according to the invention for dimensions such as are typical for probing elements for dental devices), these parameter ranges result in the plastic material being able to be shaped and / or aligned in the context of the application according to the invention, for example by the user. Another possible
    CH 715 095 A2 application is to achieve reusability and sterilizability (by heating). It is also possible within the parameter range to achieve a desired (increased) stiffness of the thin probe elements. It is not within the scope of the invention to achieve all of the properties mentioned at the same time. Rather, it is a question of the materials defined according to the invention being particularly suitable for achieving individual properties and certain combinations thereof.
    The property of changeability or malleability is to be understood, for example, as a plastic deformability, with an orientation of the probe being changed relative to the undeformed longitudinal direction. It is not excluded here that the probe is also deformable in cross section, but the deformability is primarily to be understood as a change in the inclination of the probe at a desired angle in relation to an original longitudinal axis.
    The flexural strength indicates when the material yields in the bending test. If the value is too high, plastic deformation cannot be achieved manually; if it is too low, the material deforms too quickly under lateral pressure. The elongation at break is an indication of how much a rod can be bent before it breaks. The material layer on the outside of the kink must allow sufficient elongation without breaking. It should be noted that materials which can be used according to the invention can also exist below the lower limit of 10% which is preferably specified. Finally, the flexural modulus specifies how a material rod behaves under transverse bending and gives an indication of the flexibility of a rod-shaped body. If the values are too low, the material is too easily bendable (for example if you want to carry out the measurement).
    According to a second particular aspect of the invention, the solution is that polyoxymethylene (POM) or polysulfone (PSU) are used as the plastic. These materials have proven to be very suitable for interdental probes. They can also be used outside of the special material parameter range mentioned above.
    According to a particular embodiment of the first aspect of the invention, the plastic is selected from the group of the following materials: acrylonitrile-butadiene-styrene copolymers (ABS), polypropylene (PP), polyethylene (PE), polyoxymethylene (POM). Polyamide (PA), polysulfone (PSU), thermoplastic elastomer (TPE).
    The deformability is realized exclusively by the material properties of the plastic of the dental device, so that no wire core is necessary within the probe. In addition, the materials can also be printed on, so that color codes can be attached to the probe, for example.
    The color codes are preferably there to directly identify the interdental brush associated with the probe section.
    It is also conceivable to design the color coding to be abradable, so that abrasion is generated on the probe at precisely that point on the probe at which there is a stop in the interdental space. This abrasion point allows the exact insertion depth and thus the associated probe section with the associated interdental brush to be determined directly. This surface coating is particularly suitable in combination with a conical configuration of the probe sections. However, it is not limited to this combination.
    POM and PSU are particularly preferred for use as a probe to determine the optimal dental brush. These materials can also be used to manufacture sterilizable probes, i.e. probes that can withstand heating to around 130 ° C. This has the advantage that the sterilization of reusable probes is not limited to chemical sterilization processes. Instead, it is possible to thermally sterilize the probes, as is customary, for example, when dealing with metallic dental devices.
    According to a particular embodiment of the invention, the flexural strength is at least 50 MPa. According to a further special embodiment, the flexural strength is a maximum of 200 MPa.
    The elongation at break is usually not more than 1000%. According to a special embodiment, the elongation at break is a maximum of 500%, in particular a maximum of 150%.
    According to a particularly preferred embodiment, the flexural modulus is a maximum of 10 GPa.
    A particularly preferred parameter range is defined by a flexural strength of 30-300 MPa and an elongation at break of at most 1000%, in particular of at most 500%. The flexural modulus can be up to 15 GPa.
    A special parameter range is further defined by a flexural strength of 50-300 MPa and an elongation at break of at most 1000%, in particular of at most 500%. The flexural modulus can be up to 15 GPa.
    [0030] A preferred parameter range is further defined by a flexural strength of 30-200 MPa and an elongation at break of at most 1000%, in particular of at most 500%. The flexural modulus can be up to 15 GPa.
    A good combination of kinkability and breaking strength results in the range of 50-200 MPa and an elongation at break of max. 500%. The flexural modulus can be up to 15 GPa.
    CH 715 095 A2 In order to ensure the widest possible range of use when measuring tooth pocket depths or interdental spaces, the probing sections have an essentially circular cross section with a diameter in the range from 0.6 mm to 1.2 mm. This has the advantage, for example, that teeth and gums cannot be injured with sharp edges. In addition, the probe is loaded symmetrically in a circular configuration of the cross section when deformed. This in turn ensures even wear when using the probe.
    The solution to the problem is defined according to a third particular aspect of the invention by the features of claim 9. The plastic deformability, so that an orientation of the probe in relation to the longitudinal direction of the probe can be changed manually (e.g. with a finger pressure), is a particularly advantageous property in order to simplify handling. This means that, unlike a flexible (i.e. elastically deformable) probe, the probe does not automatically return to the original orientation.
    [0034] Accordingly, the dental device for probing interdental spaces comprises a probe which can be inserted into an interspace and which has at least a first probing section and a second probing section which differs from the first probing section. The first probe section and the second probe section are arranged adjacent to each other in a longitudinal direction of the probe.
    The advantages here are similar to those already mentioned in connection with the dental device according to the invention as claimed in claim 1. In particular, the advantage is achieved that the probe can be adapted to the circumstances depending on the approximal location to be probed. For example, probing in the area of the incisors using a longitudinally oriented probe would be suitable. In contrast, it may be advantageous to angle the probe when probing in the area of the molars that is difficult to access, or at least to bevel it in relation to the longitudinal axis of the probe. The user can bend or chamfer the probe manually with his fingers or with a suitable tool. The dental device consists entirely of plastic. A wire core or a stabilizing material in the core of the probe, for example a wire core, is not provided.
    [0036] The probe is in no way limited to the first probing section and the second probing section. Instead, the probe may additionally include, for example, a third probe section and a fourth probe section. In addition, the probe can also have further probe sections. The different probe sections each have different diameters. As a result, each probe section differs from the other probe sections, so that the approximal movement of the relevant tooth space can always be determined by one of the probe sections. The diameters of a probing section are determined so that they correspond to the working area of a certain type of interdental brush. Thus, after inserting the probe into the interdental space up to the stop, it can be read directly which interdental brush fits this interdental space.
    According to a further advantageous embodiment, the dental device has a rigid shaft and the dental device can be plastically deformed manually at the transition between the shaft and the probe. This additionally increases the flexibility and the dental device can be adapted even better to the circumstances depending on the proximal location to be probed.
    According to a further embodiment, the probe is designed to be plastically deformable between the first probe section and the second probe section. This has the advantage, for example, that a transition from the first probing section to the second probing section can be formed like a joint or a defined kink. This enables the probe to be deformed in a controllable manner, the individual probe sections being retained in their elongated design. This also has the advantage that the probe can be returned to a completely elongated starting position in a particularly simple and reversible manner.
    According to a preferred embodiment, the probe is plastically deformable within a probe section. This has the advantage, for example, that the plastic deformability is not limited to the transition from one probe section to the adjacent probe section, but rather the probe sections themselves can also be adapted to the circumstances. This further increases the adaptability of the probe to probe interdental spaces. It would also be conceivable to realize the plastic deformability both within a probing section and at the transition from one probing section to the adjacent probing section. This would further increase the adaptability of the probe and would ensure continuous deformability of the probe.
    [0040] According to a particularly preferred embodiment, the probe sections are each cylindrical or conical. This has the advantage, for example, that the probing of the interdental spaces is not carried out exclusively by the respective diameter of an individual probing section, but is simplified by the continuous increase in cross section of the probe. This makes it possible to determine the approximal movement of an interdental space in question more precisely.
    [0041] According to an additional embodiment, a transition from the first probing section to the second probing section is designed as a conical transition. This has the advantage, for example, that the risk of injury to the gums is reduced when the probe is inserted into an interdental space. In contrast to
    CH 715 095 A2 gradual increase in individual probe sections, the different cross sections of the individual probe sections are replaced by conical flattened edges. The flattened edges are also more hygienic and offer little surface for contamination or residues.
    According to an alternative embodiment, a transition from the first probe section to the second probe section is designed as a step transition. This has the advantage, for example, that deformability of the probe between a probe section and an adjacent probe section is additionally simplified. Due to the formation of a step transition, a simplified deformability is already given by the different stiffnesses of the two adjacent probe sections at precisely this transition. Alternatively, it would also be conceivable to design the transition of the probe sections with a taper. This taper is accompanied by a local reduction in stiffness, which favors the deformability of the probe at this point. The taper would thus act as a kind of predetermined kink.
    In order to make the handling of the probe as simple as possible for a user and to implement a change of the probe, the shaft has a cross member for connecting to a handle element or a plug for connecting with a handle element. This has the advantage, for example, that both the connectivity of the probe to a grip element and the interchangeability of the probe by a new wear-free probe are provided in a particularly simple manner. A used, defective or contaminated probe can be removed from the holder of the handle element by the user and replaced by a new probe.
    According to a further particularly preferred embodiment, the shaft has a kink, so that an orientation of the probe with respect to a longitudinal direction of the shaft can be changed. Here, the shaft can be designed with a taper. This taper is accompanied by a local reduction in stiffness, which favors the deformability of the shaft at this point. The taper would thus act as a kind of predetermined kink. In this way, the probe can be adapted to the circumstances depending on the approximal location to be probed. For example, probing in the area of the incisors by means of a longitudinally oriented probe would be suitable. Accordingly, it may be advantageous to angle the shaft when probing in the area of the molars that is difficult to access, or at least to bevel it in relation to the longitudinal axis of the probe. The probe is angled or chamfered by adjusting the kink on the shaft of the dental device. Alternatively, the kink can also be realized with a ball joint or an alternative mechanical joint solution.
    The kinkability according to the invention is not to be confused with the "kink" at the end of work, as described in DE 10 348 352 (Witte). The well-known “kink” is a bend that is already created during manufacture. It is not intended that the kink is made possible by specifying certain material parameters, or that the kink can also be applied by the user.
    According to the invention the object is achieved with respect to the equipment set by claim 17 j. Advantageous embodiments can be found in the associated dependent claims. This results in advantages similar to those already mentioned in connection with the dental device according to the invention as claimed in claim 1 or as claimed in claim 7.
    [0047] The device set accordingly comprises a dental device for determining a cleaning device that is optimal for an interdental space, with a dental device for probing interdental spaces according to one of the preceding embodiments. In addition, the device set comprises at least a first cleaning device and a second cleaning device that differs from the first cleaning device.
    The device set according to the invention additionally has the advantage that a suitable cleaning device can be provided depending on the approximal gait of the interdental space in question determined by the dental device. For example, the first cleaning device can be suitable for cleaning a narrow interdental space, while the second cleaning device can be suitable for cleaning a larger interdental space. The set of devices is not limited to the first cleaning device and the second cleaning device. Instead, the device set can additionally comprise a third cleaning device and a fourth cleaning device, wherein further additional cleaning devices can also be included. Each cleaning device can have different cleaning properties.
    According to a preferred embodiment, the cleaning devices are interdental brushes. The interdental brushes can have identical or different cleaning properties. Different cleaning properties are justified, for example, by geometric properties such as the size of the interdental brush or by the material and the rigidity of the bristles or the wire in the interdental brush itself.
    According to an additional embodiment, the device set further comprises a handle element for connection to the dental device and to the cleaning device. This has the advantage, for example, that the device set does not require an additional handle element to hold the dental device on the one hand and the cleaning device on the other hand. Advantageously, only the dental device and then the cleaning device can be used with only one grip element. In this case, the identical connection is realized only for the dental device and the cleaning device, as would be possible, for example, with a crossbar connection and / or a stopper.
    CH 715 095 A2 In a particular embodiment, the device set has two groups of cleaning devices and two different dental devices for probing the interdental spaces. A first of the two different dental devices is formed from a bendable plastic body and a second of the two different dental devices from a rigid plastic body. With the two different dental devices, very different interdental spaces can be better probed. The types of cleaning devices (in particular interdental brushes) provided as part of the system are therefore divided into two groups. A probe is assigned to each group.
    [0052] The dental probes are preferably assigned to the cleaning devices via a color code. The coding space spanned by the various cleaning devices is divided between the two probes (dental devices).
    A display stand can be added to the device set, on which the entirety of the cleaning devices is presented. For example, the presentation can take the form of conventional transparent packaging, with several identical cleaning devices being contained in one packaging. The packaging is hung, for example, on hooks of the presentation surface arranged in a distributed manner. According to a special embodiment, the presentation stand has two presentation pages (which, for example, form the front and back of a vertically standing support wall).
    The first group of cleaning devices, which are assigned to the first dental device, and the second group of cleaning devices, which are arranged to the second dental device, are held on the one presentation page. This makes it easier to find the cleaning devices determined with the dental device. In addition, it can be practical if the presentation stand has a stand and a plate-like product holder that can be rotated relative to the foot.
    From the following detailed description and the entirety of the claims, further advantageous embodiments and combinations of features of the invention result.

    WAYS OF IMPLEMENTING THE INVENTION FIG. 1 shows a probe 110 for probing interdental spaces with four probe sections 112, 114, 116, 118. The four probe sections 112, 114, 116, 118 each have a different thickness, the strength increasing from the first probing section 112 to the fourth probing section 118. Each probe section 112, 114, 116, 118 has a round diameter, as a result of which each of the probe sections 112, 114, 116, 118 has a cylindrical basic shape. The cross section of each section increases abruptly at each transition, as a result of which each transition is designed as a stepped transition 120.
    CH 715 095 A2 FIG. 2 shows a probe 110 for probing interdental spaces with four probe sections 112, 114, 116, 118, the probe 110 being deformed between two adjacent probe sections. The deformation is formed between the second probe section 114 and the third probe section 116. The first probing section 112 and the second probing section 114 as well as the third probing section 116 and the fourth probing section 118 each form a common straight line in pairs, since the deformation of the probe 110 only affects the abrupt transition 120 between the second probing section 114 and the third probing section 116 limited. The deformation is to be understood as a change in the orientation of the probe 110 relative to its longitudinal direction in the undeformed state.
    FIG. 3 shows a probe 110 for probing interdental spaces with four probe sections 112, 114, 116, 118, the probe 110 being plastically deformed within the second probe section 114. Each probe section 112, 114, 116, 118 is thus not designed as a deformation-resistant element, but rather has a continuously formed deformability. This can be achieved, for example, with the appropriate plastic. Likewise, the probe 110 can consist of individual elements that are connected to one another. This can be achieved, for example, by a large number of articulated components. The joint-like components can be formed at the transitions or also within each probe section 112, 114, 116, 118.
    4 shows a probe 110 for probing interdental spaces with three probe sections 112, 114, 116, the transitions between the probe sections 112, 114, 116 being designed as conical transitions 122. The conical transitions 122 have in particular a reduced susceptibility to deposits or contamination and are therefore advantageous from a hygienic point of view. The surface material of the conical transitions 122 can be identical to the surface material of the probe sections 112, 114, 116. Alternatively, however, it is also possible to provide the surface material at the conical transitions 122 with a different material. This would be conceivable, for example, in connection with an embodiment which is articulated at the transitions. For example, a softer surface material would be suitable for a simplified adjustability or deformability of the probe 110. Likewise, the wear on these conical transitions 122 can be reduced by suitable choice of material. In contrast, the surface coating of the probe sections 112, 114, 116 could be provided with a harder material to compensate for the mechanical load when it is inserted into the interdental spaces.
    5 shows a probe 110 for probing interdental spaces with three probe sections 112, 114, 116, the transitions between the probe sections 112, 114, 116 being designed as conical transitions 122. The probe 110 is plastically deformed between the first probe section 112 and the second probe section 114. Likewise or alternatively, the probe 110 could be plastically deformed between the second probe section 114 and the third probe section 116. It is also conceivable to design the probe 110 with such conical transitions 122 and to provide plastic deformability also within the individual probe sections 112, 114, 116.
    6 shows a probe 110 for probing interdental spaces with four probe sections 112, 114, 116, 118. The probe sections 112, 114, 116, 118 are conical. The conical configuration of the entire probe 110 extends continuously from the probe tip of the first probe section 112 to the end of the fourth probe section 118, which has the largest diameter. The interdental spaces are probed with the aid of the continuous increase in cross-section of the probe 110 and is thereby considerably more precise. Such an embodiment of the probe 110 can be combined, for example, in connection with a color-printed or abradable surface of the probe 110. If the probe 110 is inserted into an interdental space with the continuous increase in cross-section, the probe 110 remains stuck in accordance with its largest possible diameter. If discoloration or abrasion now results from the mechanical action of the teeth on the probe 110, subsequent determination of a suitable cleaning device (not shown) is particularly simple. This embodiment is particularly conceivable in connection with a continuously formed deformability of the probe 110, for example by means of a suitable plastic. This results in the advantage for a user of the probe 110 that he can manually shape the probe 110 in order to ensure that it is used even in hard-to-reach places in the dentition. Due to the continuously formed deformability, there are no restrictions for the exact location of the deformation. Instead, the user can carry out the deformation on each of the four probe sections 112, 114, 116, 118 for a specific purpose.
    7 shows a probe 110 for probing interdental spaces with a shaft 140. The shaft 140 extends in the longitudinal direction of the probe 110 and extends it after the fourth probe section 118. It would also be conceivable that between the fourth Probe section 118 and the shaft 140 further probe sections are arranged. The shaft 140 has approximately the same length as the fourth probe section 118. The length of the shaft 140 must at least take into account the stabilization of the probe 110 during use and has a cross member 142 for attaching the probe 110 to a handle element 200 (not shown). Instead of the cross member 142, any other means can be arranged on the shaft 140, which enables a non-positive and exchangeable, as well as easy to handle connection to a handle element 200 or its holder 210 (not shown).
    8 shows the probe 110 for probing interdental spaces according to FIG. 7 with a deformed shaft 140. The shaft 140 adjoining in the longitudinal direction of the probe 110 is deformed in the middle between the fourth probe section 118 and the cross member 142. The deformation of the shaft 140 can be caused, for example, by An
    CH 715 095 A2
    Order of a joint or a kink can be realized. The deformation of the shaft 140 additionally improves the handling of the dental device 100 and facilitates probing in areas of the dentition that are more difficult to access. 9 shows four different cleaning devices 212, 214, 216, 218 in the form of interdental brushes with different cleaning properties. The different cleaning properties of the interdental brushes are defined in particular by different brush sizes. Depending on the probed interdental spaces, the suitable size for use is immediately obtained. The size of the interdental brush is determined by its length and its diameter, but also by the hardness of the respective bristles. In addition, the degree of flexibility of the brush wire can also be decisive for the suitability of the interdental brush.
    10 in combination with FIGS. 8 and 9 shows a device set 300 for determining a cleaning device suitable for an interdental space. The device set 300 basically comprises the dental device for probing the interdental spaces (cf. e.g. FIGS. 7 and 8). The device set 300 also includes the cleaning device set (e.g. interdental brushes of different sizes) assigned to the dental device via a code (e.g. a color code) that can be read directly.
    According to the present particular embodiment, the handle element 200, a holder 210 arranged on the handle element 200 and the dental device 100 attached to the holder 210 for probing interdental spaces also belong to the device set. A neck 220 disposed between the handle member 200 and the bracket 210 has a curved or kinked (i.e. angled) shape. This curved shape could also be realized by means of an articulated element. This results in the already known advantages of a device set that can be individually adapted to the intended use.
    11 shows a presentation stand 310 which comprises a first presentation page 311 and a second presentation page 312. The cleaning devices which belong to a first group of cleaning devices 321 are arranged on the first presentation page 311. The cleaning devices of the first group of cleaning devices 321 are assigned to a first dental device, or vice versa, the cleaning devices of the first group of cleaning devices 321 are assigned to the first dental device. The (first) cleaning device is e.g. a rigid probe 330. (The property “rigid” in this specific context means that the probe cannot be plastically deformed by the user manually.) And the assigned cleaning devices 321 are e.g. particularly voluminous or rather long-bristled interdental brushes.
    The cleaning devices which belong to a second group of cleaning devices 322 are arranged on the second presentation page 312. The cleaning devices of the second group of cleaning devices 322 are assigned to a second dental device, or vice versa, the cleaning devices of the second group of cleaning devices 322 are assigned to the second dental device. The (second) cleaning device is e.g. a bendable probe 331 according to the invention. This means that it can be plastically deformed manually by the user. And the associated cleaning devices 322 are e.g. particularly fine or rather thin interdental brushes.
    The presentation stand 310 can have a stand 314, the upper part of the presentation stand 310 being rotatable relative to the stand 314.
    The cleaning devices are e.g. hung in packs of 10 on presentation stand 310. However, they can also be provided in individual packaging. In this case, the nursing staff can use individual brushes to check whether the interdental brush determined with the dental probe really fits the interdental space (e.g. for special tooth positions or interdental spaces).
