A manufacturing method for a prosthetic apparatus for dental purpose according to one aspect of the present invention includes: acquiring scan data of a model that is a reproduction of at least a part of an inside of an oral cavity of a patient; creating shape data of a shaped body for dental purpose on a basis of the scan data; producing a shaped body on a basis of the shape data; covering at least a part of the shaped body and at least a part of a model with film, the shaped body attached to the model; releasing air in a part covered with the film to deform the film and bring the shaped body into close contact with the model; and curing the shaped body in a state where the shaped body is in close contact with the model.

The invention relates to a method for constructing at least one dental prosthetic part or a bracket, with at least one adhesive surface, in which a 3D model is made of the dental prosthetic part. Recesses are constructed on the adhesive surface of the 3D model.

A virtual model of an intraoral cavity is provided, wherein this process is initialized by a dental clinic, and the design and manufacture of a suitable dental prosthesis for the intraoral cavity is shared between a dental lab and a service center.

A zirconia sintered body for dental use may not require coloring or firing after shaping, and have aesthetic properties. A preform may include a body and a stem. The body has a Vickers hardness of 4 to 20 HV (GPa), and is machinable. The stem has a width of 4 mm or less at a position where it protrudes from a central portion of the body. At this position, the central portion has a cross-sectional geometric shape with an inscribed circle having a diameter of >12 mm, and a circumscribed circle having a diameter of <20 mm. The body shows a color change from an upper to a lower end portion of the body, and unchanging patterns of increase and decrease of the L*a*b* color system values from the upper to the lower end portion. The preform can be shaped into a dental restoration such as a crown.

The present invention relates to a method for manufacturing a prefabricated crown by processing and tabulating the type, size, material and color of prefabricated crowns for sub-gingival and supra-gingival, and actual and try-in crowns by a table system (1), and a prefabricated crown manufactured therefrom, and the method includes a first step (S100) of classifying a plurality of prefabricated crowns by type and size by a first module (5) of the table system (1); a second step (S110) of classifying the plurality of prefabricated crowns by color and material by a second module (7) of the table system (1); a third step (S120) of tabulating the type, size, color and material data of the prefabricated crowns classified in the first and second steps (S100, S110) by a third module (9) of the table system (1), and assigning an identification code to each data; a fourth step (S130) of manufacturing the tabulated plurality of prefabricated crowns; and a fifth step (S140) of inputting the measured type, size, color and material data of patient's tooth into a fourth module (11) of the table system (1) to select a prefabricated crown corresponding thereto.

Methods for manufacturing anatomical healing caps, including forming an anatomical healing cuff body for a given tooth position, the anatomical healing cuff body having a cross-section and an exterior surface so that the anatomical healing cuff body provides substantially custom filling of at least an emergence portion of a void where a natural tooth once emerged from the void or where a tooth would have emerged from a void of the given tooth position, and forming both lateral buccal and lingual handle extensions extending from the anatomical healing cuff body so that the manufactured anatomical healing cap includes a laterally extending buccal handle extension and an oppositely disposed laterally extending lingual handle extension, the buccal and lingual handle extensions being integrally formed with the healing cuff body. The healing caps can be formed using a casting jig, by machining, by 3D printing, or other suitable methods.

A system and method include digitally determining a virtual insertion path of a digital dental restoration,

A system for generating missing data for 3D models of intraoral structures of a patient. The system may include a hand-held intraoral scanner and a computer having instructions that the system to scan the intraoral structure of a patient to generate first 3D data of the surface of a prepared tooth, generate a 3D virtual model of the prepared tooth based on the first 3D data, determine the 3D virtual model is missing a surface associated with the prepared, generate second 3D data approximating the surface that is determined to be missing from the 3D virtual model intraoral structure that is missing, and combine the second 3D data with the 3D virtual model such that the 3D virtual model includes the approximated surface, wherein the approximated surface approximates the prepared tooth associated with the surface determined to be missing from the 3D virtual model.
