    [0002] MODEL FOR TEACHING IN DENTAL DISCIPLINES
    [0004] OBJECT OF THE INVENTION
    [0006] The invention, as expressed in the wording of the present specification, refers to a model for teaching in dental disciplines that provides, to the function to which it is intended, advantages and characteristics, which are described in detail below, which represent a improvement for the current state of the art.
    [0008] The object of the present invention lies, specifically, in a teaching model that reproduces some part of the human or animal stomatognathic system, said part being able to consist of a single dental piece, several teeth or a jaw bone, including or not dental pieces, which It is distinguished, basically, by the fact of being manufactured from structures that, emulating the different tissues or states of the same that they reproduce and to offer realism in the practice of their use by the student, comprise differentiated areas, which will be or others depending on the specific discipline to which each model is intended in its various variants, with different mechanical properties defined by a different density and, eventually, color. Specifically, the model of the invention contemplates an embodiment variant with a structure specifically applicable for learning dental anatomy, a variant for learning the opening of cavities and / or predefined dental preparations, and a variant for learning the removal of decayed dental tissue. In addition, preferably, the model has means for fixing it to a phantom and allowing practice in the actual position that the student will be in to carry out the work.
    [0009] FIELD OF APPLICATION OF THE INVENTION
    [0011] The field of application of the present invention is framed within the sector of the industry dedicated to the manufacture of models for teaching, focusing particularly on the field of those intended for the practice of dental disciplines.
    [0013] BACKGROUND OF THE INVENTION
    [0015] There are now different types of anatomical models for teaching practices in many fields, including dentistry.
    [0017] On the other hand, in most practical programs in dental pathology and therapeutics at universities, bars of soap, wax or other materials are used to acquire said anatomical knowledge and cutting skills, with problems of proportionality, size and variations of the teeth. anatomical structures, and therefore the student's work is limited only to carving without guides until obtaining a structure similar to the real anatomical model, since there are no anatomical learning models using subtraction techniques.
    [0019] Regarding dental models, there is currently a great variety of dental models that faithfully reproduce the natural anatomy of each tooth, allowing the opening and design of cavities and / or preparations by the students. Frasaco ® offers an extensive program of educational products with study materials, as does Nissin Dental Proucts INC.
    [0021] The main problem is that these dental models reproduce healthy teeth with caries-free anatomy, decayed teeth in which the student experiences the sensation of cutting by opening cavities and / or preparations following the specifications dictated by Black (GV Black, 1895) or specific preparations described by the teacher in order to acquire the necessary skill in handling cutting instruments, But the fact that there are no defined limits or established cutting pattern, which means that in the development of the practice the student makes cavities and / or imprecise, disproportionate preparations, and ultimately does not acquire the necessary dexterity to guide the instrument of cut properly.
    [0023] Nissin Dental markets the CON2001-UL-SP-FEM-32 Operative Jaw Model and the CON2001-UL-UP-FEM-32 Operative Jaw Model, both for the purpose of learning operative techniques, but without defining the area to be removed and therefore without the capacity for precise motor learning.
    [0025] Like Nissin Dental, Frasaco offers dental models of healthy teeth that correspond to a typical natural adult denture made of duroplastic, the main use of which is described for the practice of preventive, conservative and prosthodontic dentistry, as they are natural teeth healthy allow any type of manipulation with cutting instruments, and therefore do not offer the possibility of performing psychomotor exercises or acquiring precision in the handling of cutting instruments.
    [0027] The objective of the present invention is, therefore, to provide an improved type of models for teaching that allows greater realism in the student's practice through a more faithful reproduction of the different mechanical properties of the different tissues and areas of the part of the oral or dental system to be treated.
    [0029] On the other hand, and as a reference to the current state of the art, it is Note that, at least by the applicant, the existence of any other model for teaching in dental disciplines or of any other invention of similar application that presents technical, structural and constitutive characteristics equal or similar to those presented here is unknown. claimed.
    [0031] EXPLANATION OF THE INVENTION
    [0033] The model for teaching in dental disciplines that the invention proposes makes it possible to solve the drawbacks described in the current models and satisfactorily achieve the aforementioned objectives, with the characterizing details that make it possible and that distinguish it conveniently included in the final claims that accompany the present description.
    [0035] More specifically, what the invention proposes, as indicated above, is a model for teaching of the type that reproduces some part of the human or animal stomatognathic system, part that consists either of a set that comprises a mandibular and / or maxillary area. or a portion thereof, including one or more teeth and / or edentulous areas, or only in a specific, temporary or permanent tooth, or a group of two or more adjacent teeth, and is basically distinguished by the fact of being manufactured from structures that, emulating the different tissues that reproduce and / or their natural or affected state, comprise areas with different mechanical properties differentiated from each other by the fact that they present, at least, a different density and that, eventually, also present a different color, providing optimal realism in the practice of its use by the student, serving in certain cases also as a system. guideline to facilitate learning of the work to be done.
    [0036] It should be noted that the aforementioned areas of the model with the described different mechanical properties defined by a different density, will be one or the other in each case, depending on the type of specific model and the discipline to which it is intended, so it presents different Variants applicable to learning different types of work, being able to present, in addition to different density and different color, different porosity and / or different elasticity and / or different flexibility.
    [0038] Specifically, the model of the invention contemplates a first variant of embodiment with a structure specifically applicable for learning dental anatomy, a second variant of embodiment in which its structure is specifically designed for learning the opening of cavities and / or predefined dental preparations and a third variant embodiment in which the structure of the model is specifically designed for learning to remove carious dental tissue.
    [0040] In addition, preferably, the model object of the invention, in one, several or all of its variants, contemplates the inclusion of means to ensure its fixation to a phantom, normally a head, and allow the student to practice in the actual position that will be found to get the job done.
    [0042] Going further into the details of the invention, the model of the invention contemplates in a first embodiment variant, applicable for learning dental anatomy, the structure of the model reproduces a single tooth, several teeth, or a complete arch, which , in order to allow the student to acquire, by means of subtraction techniques with manual cutting materials, the knowledge of the anatomical characteristics of each of the teeth to be treated, they are integrated in an external body "lascable" or "removable" of different density and preferably also of different color, than the The student must remove until exposing the interior piece or pieces, being able to contemplate the inclusion of several pieces or groups of pieces of different proportions integrated into each other, logically from highest to lowest, where the student by the aforementioned subtraction techniques must expose different scales marked by changes in density and chromaticity, the dental anatomical structure, accessing proportions or lower scales as skills in anatomy and dexterity in the handling of instruments are acquired. Preferably, the outer body is a polyhedron, although this is not a limitation.
    [0044] More specifically, in this first variant of embodiment, applicable in learning anatomy, the structure of the model reproduces a temporary or permanent tooth, human or animal, with a complete anatomical design, included inside an external body, preferably a shape polyhedral, formed by a multichromatic composition, that delimits similar dental structures in different proportions scales (from highest to lowest) that vary in hardness and density to improve training in the handling of cutting instruments in different types of preparations.
    [0046] The present invention allows to predefine the anatomical figure to be made by the student by means of different colors that allow differentiating the different size scales of the same, preferably comprising:
    [0048] - A polyhedral outer area to be removed with a color and density different from the rest, which will expose after removal a dental anatomical shape of a specific piece at a 3X scale, with a different color and density than the outer area.
    [0049] - A 3X scale tooth, which can again be removed with cutting instruments, of a different color and density than the rest that you will discover the same anatomical figure on a 2x scale.
    [0050] - A 2X scale dental piece, which can also be removed with the cutting instruments, of a different color and density than the rest, and which will reveal the same anatomical figure on a real-size scale (approximately natural tooth size). With exact anatomical characteristics to the previous ones.
    [0052] The polyhedral shape of the external body, in which the dental anatomical figure is included, can vary both in shape and thickness, depending on training or skill acquisition needs. Similarly, the scale sizes may vary according to the sector to which the models are directed and the skills in the handling of cutting materials.
    [0054] In a second variant of embodiment, for learning the opening of cavities and / or predefined dental preparations, the model allows to acquire the skill and precision necessary in the intraoral handling of both manual and rotary dental cutting instruments, for which its structure reproduces a piece or group of temporary or permanent teeth in which at least one area of density different from the rest is contemplated in order to be eliminated and whose shape, hardness and density, in addition to its color, may vary depending on the teaching need of the training in the handling of cutting instruments in the different types of preparations.
    [0056] Thus, this variant of the model of the invention makes it possible to predefine the preparation to be carried out by the student by means of different densities and colors that make it possible to differentiate the part of the tooth to be removed from that to be preserved.
    [0058] More specifically, the preferred embodiment of this variant of the model, the structure reproduces a single dental piece comprising:
    [0059] - An area to be removed with the cutting instruments, of a different color and density from the rest.
    [0061] - An area of the tooth to be preserved, with a different color and density than the area to be removed.
    [0062] - An intermediate zone to be conserved with a color and / or density different from the rest, which acts as an interface between the zone to be eliminated and the zone to be conserved, establishing the limit to which the student must extend the preparation.
    [0063] - A phantom compatible base that allows insertion into practice models, for example ANA-4, AG-3 and A3 from Frasaco.
    [0065] The model of this variant for teaching in the opening of cavities and / or predefined preparations can be developed individually, so that it can be attached to a phantom using a compatible base, or it can be developed as part of a practice phantom in a fixed way, without the possibility of individualizing the teeth.
    [0067] Finally, the model contemplates a third variant of implementation applicable for learning how to remove carious dental tissue that allows acquiring the necessary dexterity in the intraoral handling of dental cutting instruments, both manual and rotary, in the removal of carious tissue, both in cases of single involvement of the hard tissue as in cases of involvement of the pulp tissue, for which its structure reproduces a piece or group of temporary or permanent teeth in which at least one area of density different from the rest that emulates a caries lesion to be removed with cutting instruments.
    [0069] In addition to reproducing healthy and diseased tissue, in this variant the model, preferably, it also reproduces the pulp tissue, so that the student must establish and apply real therapeutic criteria when removing the hard tissue due to the possibility of finding or generating pulp damage.
    [0071] This variant therefore allows the student to make preparations on the models by removing the hard tissue with dental cutting instruments and their subsequent filling, making use of different materials and restoration techniques according to the needs generated in each case.
    [0073] In the preferred embodiment of this variant, the structure of the model reproduces a single dental piece comprising:
    [0075] - An area to be removed with cutting instruments, with a density and consistency similar to decayed, infected and irreversibly affected tissue.
    [0076] - An area of the tooth to be preserved, with a density similar to the healthy tooth, and different from the area of decayed tissue to be removed.
    [0077] - An area to be preserved with a density and consistency different from the rest that reproduces the area of the injury to be preserved due to its recovery capacity.
    [0078] - An area of pulp tissue, with a density and consistency different from the rest, with the ability to reproduce the color and vitality of healthy pulp and the possibility of incorporating sensors that record the damage caused by errors in the removal of hard tissue.
    [0079] - A phantom-compatible base that allows insertion in practice models, for example ANA-4, AG-3 and A3 from Frasaco.
    [0081] As in the previous variant, the model in this variant for teaching in carious tissue removal can be developed individually, so that it can be attached to a phantom by means of a compatible connection, or it can be developed as part of a practice phantom in a fixed way.
    [0083] DESCRIPTION OF THE DRAWINGS
