    BLOCK FOR THE MANUFACTURE OF INDIVIDUALIZED MUNONS FOR DENTAL IMPLANTOLOGY AND MANUFACTURING PROCEDURE OF A PERSONALIZED MUNON FOR DENTAL IMPLANTOLOGY
    D E S C R I P C I O N
    OBJECT OF THE INVENTION
    The present invention relates to a block for the manufacture of individualized worlds for dental implantology and to the method of manufacturing a customized world for dental implantology, of the type that is applicable in dental implantology to be fixed screwed to a previously osseointegrated implant, normally in an incorrect position, and place aesthetic material, which will give shape and color to the tooth, directly on the munon without using a dental crown on the munon. Said block has the particularity of comprising a structure designed to be able to choose the input angulation that the channel used for the introduction of the fixation screw to the implant must have.
    The field of application of the present invention is framed within the dentistry sector, focusing particularly on the field of industry dedicated to the manufacture of accessory parts and elements for the manufacture of dental prostheses, in particular for the manufacture of implant prostheses. Dental
    BACKGROUND OF THE INVENTION
    The technical problem that the present invention aims to solve is that, in many cases, the implants are incorrectly placed in the patient's bone and its vertical axis, which will determine the position of the prosthesis screw to be installed later, remains located so that the placement of said prosthesis is unsightly and / or impairs its functionality.
    Currently, structures for dental prostheses are manufactured with CAD-CAM technology (Computer-Aided Design), computer-aided design and Computer-Aided Manufacturing, computer-aided manufacturing, reducing the errors of traditional manufacturing by lost wax casting processes.

    One of the structures manufactured in CAD-CAM are worlds with an emergency profile and custom shape for each patient and situation, which are subsequently atomized to the implant. On this munon a dental crown or dental prosthesis will be cemented with the shape and color of the tooth that will completely cover the munon.
    When the implants are placed incorrectly and their vertical axis does not allow the correct placement of the screwed prosthesis, since the entrance / exit hole of the implant fixation screw is located in an aesthetic or important area for the functionality of the prosthesis or because the result would be unsightly or detrimental to the functionality of the prosthesis, it is necessary to cover the entire world of the prosthesis by a cemented dental crown. This solution has as main drawbacks that:
    - the removal of the prosthesis is prevented if necessary, since if there is a problem with the screw that fixes the customized munon to the implant, it would be necessary to break the cemented crown located above to access the screw access channel, and
    - It implies the need to make two structures, the munon and the crown.
    However, if the implant is correctly placed in the patient's bone, the screw channel hole will be located correctly, so that the aesthetic material, which will give shape and color to the prosthetic tooth, can be placed directly on the prosthesis or munon, thus having a prosthesis screwed and not cemented as in the case described above.
    For the manufacture of these worlds there are on the market blocks or cylinders of Titanium (fig. 1) that have the connection to the implant already pre-machined in the block itself. The machining process of said implant connection is very delicate and has to be very exact in measurements and tolerances, which is direct to achieve with the mills of the current dental sector, so these pre-mechanized connections with machines are offered High precision CNC, in order to facilitate the work of dental technicians who only have to mechanize the block body externally that does not require great accuracy to form the munon to be installed on the implant. With these blocks you can be sure that this connection is perfect between the implant and the block itself. Subsequently, the block is modeled by milling the concrete design on the block itself to give rise to the munon.

    Specifically, these blocks of the state of the art (fig. 1) comprise:
    - A cylindrical body,
    - A pre-machined connection base, in the lower part of the cylindrical body, whose shape will be determined by the shape of the implant connection,
    - A through and vertical channel through which the screw that fixes the block to the implant is passed, once the outside of the block has been milled and turned into a munon, and through which a screwdriver will also be introduced that will act on the screw head for fixing this to the implant,
    - An internal milling that shapes the settlement of the head of said fixation screw to the implant, and
    - A grip protrusion that has the geometry of the support of the milling machine, to be able to fasten the block to said support and to be able to shape the munon by milling the block.
    These blocks, however, have an important limitation since the screw inlet / outlet through channel for fixation with the implant is straight and pre-machined, coinciding with the axial axis of the cylindrical body that forms the block and with the axis of the implant, so that when the position of the implant is not correct, it is not possible to change the direction of the screw inlet channel and it is necessary to cement the crown on the munon to cover the hole of the inlet / outlet channel of the screw.
    The applicant is aware of the existence of a block (fig. 2 and fig. 3) that has an inlet channel for the fixing screw that starts from the outer surface of the block to the settlement of the head of the fixation screw to the implant. Said channel, instead of coinciding with the axial axis of the cylinder of the block body, has a fixed and pre-machined angulation of 11 ° with respect to said axis, being able to solve only in a very small percentage the problems of incorrect position of the dental implant . This solution has the same problem as the conventional block with straight through channel and parallel to the axial axis discussed above. The through channel is pre-machined at an angle of 11 ° without allowing the technician the option to modify said angle, and thus limiting the possibility of being able to directly manufacture a munon with aesthetic material if the necessary angle for rectification exceeds 11 °.

    The main difference between the blocks of the state of the art and the block object of the present invention is that the blocks of the state of the art have a fixed angulation of 0 ° or 11 °, which is predetermined and pre-machined without the possibility of manipulation or adaptation. However, the block object of the present invention does not have a pre-machined angled channel allowing to choose the desired or required angulation to be machined, as designed, at a later stage next to the shape of the custom world designed, by CAD / CAM.
    The objective of the present invention is, therefore, to develop an improved type of block for shaping the munon whose input channel for the implant fixing screw can be angular according to the needs of each specific case.
    EXPLANATION OF THE INVENTION
    The present invention relates to a block for the manufacture of individualized worlds in dental implantology according to revindication 1 and to a method of manufacturing a customized world according to claim 5. Said block used for the subsequent manufacture of individualized worlds is applicable in Dental plantology for the fixation screwed to the implant that has previously been integrated in the bone without taking into account that the position of the implant in the patient's bone is correct or incorrect, allowing to fix directly on the implant the custom and covered munon with the aesthetic material that will give shape and color to the dental piece.
    In particular, the block for the manufacture of customized or individualized worlds comprises a cylindrical body with an axial axis; a connection base in the lower part of the cylindrical body with an inner channel to connect with the dental implant and an axial axis coinciding with that of the cylindrical body; an internal machining that determines the settlement of the head of a fixing screw for screwing between the block and the dental implant; and a grip protrusion to hold the block to the support of a machine and allow its external machining, also having a blind vertical channel section following the settlement of the head of the fixing screw, the axis of the channel section being blind coincident with the axial axis of the cylindrical body.
    Thus, the block object of the invention is a block for the manufacture of a
    5
    10

    25
    30
    munon for dental implantation ^ which presents as the main difference with respect to the state of the art that it has a straight and blind section on the mechanized settlement of the screw, and from which, in a second phase of machining to be performed by a technician. The technician, in addition to designing the outer shape of the munon, will design an angled inlet / outlet channel of the fixing screw by CAD / CAM at the end of the end of the blind vertical channel section of the block. Said angle may be between 0 ° and 40 °, which is the limit to be able to act on the screw by means of a screwdriver, with respect to the axial axis of the cylinder body.
    Said blind vertical section located next to the settling of the fixation screw to the implant, allows the subsequent screwing of the munon in the implant with different angles by allowing the entry / exit of screws of different lengths through a through channel that is made in the block, that is, the height of the blind vertical channel section will be defined by the length of the screw, which is determined by the type of implant, since this has to pass through the angled channel and be positioned vertically with the implant to be screwed. The length of the vertical blind channel section is variable and depends on the length of the fixing screw and the type of connection required by the implant. Likewise, the internal machining that determines the settlement of the head of the fixing screw is located between the end of the section of the blind vertical channel and the connection base.
    The screws and tool used to fix the block with the angled channel are preferably screws and tools specifically designed for this purpose, although they are not part of the object of the present invention.
    In any case, the possibility of angular power to the channel and to be able to resituate the screw inlet or outlet hole freely provides time and step savings in the fabrication of the prosthetic crown, since it is possible to place the aesthetic material (which is what it will give shape and color to the prosthesis) directly on the structure or world, manufacturing the prosthesis in a single phase and with a single structure from the block object of the present invention.
    Specifically, the block described is configured, as described, from a metal part comprising a cylindrical body, with a pre-machined base, of connection at the bottom of said cylindrical body, and whose shape will be determined by the shape of the connection of the implant on which the prosthesis will be screwed, and that, instead of a through and vertical channel for the passage of the fixing screw, it has a section of vertical blind channel from which it will be designed with

    CAD-CAM, a second through channel that could be angled between 0 ° and 40 ° with respect to the axial axis of the cylinder, which is carried out at a later stage of fabrication of the block in addition to the machining of the outer surface of the block to form The munon
    Likewise, the block, which may be manufactured in Titanium, Cr-Co, Tilite, or in any metal alloy or synthetic material used in the dental sector, has a grip protrusion that has the geometry of the support of the machining machine, to be able to fasten the block to said support and shape the munon. This protuberance can be on the vertical axis of the block or on one side. The shape, size or position of this protuberance will depend on the design of the support of the machining machine used in each case.
    Likewise, the process for manufacturing a custom munon of the invention comprises:
    - A design phase, in which from the block as described, and preferably by means of a design software (CAD), the trajectory and angle with respect to the axial axis of a through channel located between the end of the section of the vertical blind channel and the exterior of the block, as well as the exterior shape of said block, all this is defined based on the conditions of the installed implant,
    - A machining phase, in which said block is machined by machining said through channel between the end of the blind vertical channel section and the outside of the block to allow the fixation screw to pass to the implant, thus communicating the end of the section of vertical blind channel with the outside of the block, according to the definition made in the design phase, and
    - An additional machining phase - in which the exterior of the block is machined according to the definition made in the design phase and that will shape the body of the munon that will later receive the aesthetic material that will finally shape and color the dental piece .
    The two previous machining phases are carried out in the same machining machine and even at the same time.

    internally, to allow after its machining the passage of the screw (not shown) of fixation to the implant, a section of blind vertical channel A1, coinciding with the axial axis (e) of the cylindrical body CC and of the implant, located next to a machining or internal milling AT that determines the settlement of the head of the fixing screw between the munon and the implant. Depending on the position of the implant, it will be necessary to make a through-channel CP with one or another angulation with respect to the end of the blind vertical section A1 of the block, and for this, after calculating and designing the angulation of said passing channel CP, said machining is machined second pass-through channel CP between the end of the vertical blind channel and the outside of the block. After machining, the through channel CP at its opposite end to the AT settlement, opens to the outside, presenting an angle (a) between 0 ° and 40 ° with respect to the axial axis (e) of the cylindrical body and with respect to the axis of the implant . Said pass-through channel CP is machined, like the outer surface of the block to form the munon, by CAD-CAM technology.
    The height of the section of the blind vertical channel A1 is variable, being defined by the length of the screw so that it can pass through the angled channel CP and be positioned vertically with the implant to be screwed.
    Once the custom munon is manufactured, it is placed on the implant and through the CP through-channel the fixing screw is introduced, which will pass through the angled CP through-channel, the vertical section A1, which after machining is not blind, and after reaching the head of said screw the pre-machined AT settlement in the munon, crossing the connection base B1 with the implant, a screw tool is introduced through the pass-through channel CP until the screw head is reached to tighten between the munon and the implant Subsequently, the aesthetic material, usually ceramic, that forms the prosthetic tooth is arranged on the munon.
