Dental instruments, assemblies, and components for a dental instrument are described with a two-piece tip that includes a flexible tip end and a stiff shank. Various methods of assembly are described for securing the flexible tip end to the shank including utilizing a slot in the shank and one or more pins inserted through the tip and shank, a securing material, and forming the shank with a distal portion coupled to a portion of the flexible tip end.

A set of artificial teeth for a denture comprises a maxillary unit and a mandibular unit. When set up in lingualised occlusion, at least one of following occurs: the palatal cusp of the upper 4 (1) fits into the distal fossa of the lower 4 (6), the palatal cusp of the upper 5 (2) fits into the distal fossa of the lower 5 (7), the mesial palatal cusp of the upper 6 (3) fits into the central fossa of the lower 6 (8), the distal palatal cusp of the upper 6 (4) fits onto the marginal ridge of the lower 6 (9) and the mesial palatal cusp of the upper 7 (5) fits into the central fossa of the lower 7 (10). The buccal cusps of the lower teeth are out of contact with the upper teeth, such that the cusp/fossa dimensions and relationships of the teeth concerned enable the occlusal scheme for the teeth to be changed from lingualised to balanced occlusion simply by softening the wax or resin under the upper posterior teeth and rotating the upper buccal cusps downwards around the said palatal cusps on the upper teeth with such palatal cusps still substantially remaining within the centric stops of the lowers.

A tooth implantation technique and a subperiosteal implant manufacturing method for the solution of extreme atrophy of a tooth bone are disclosed, primarily using steps of tomography, data transformation, software design, 3D printing of a physical model, making a subperiosteal implant wax form, wax form scanning and design, and manufacturing with a CNC milling machine, so as to make a subperiosteal implant that fits with a patient, thereby improving the shortcomings in a conventional manufacturing procedure of an implant.

Providing a surface treatment agent for a wax pattern containing solvent; boron nitride; and a surface-active agent.

A dental all-ceramic restoration and manufacturing method thereof; the outer surface of the dental all-ceramic restoration has neither visible marks remaining from the removal of the connecting bars (7) nor local grinding traces and chipping, and is smooth with uniform structure. The manufacturing method thereof is wet-forming or milling. No connecting bars are needed to connect the dental restoration bodies (3) with a surrounding mould blank or ceramic blank. This eliminates the need for manually cutting off the connecting bars (7) to separate the forming body from the surrounding ceramic blank, further grinding and polishing process to treat the excessively rough outer surface, and thereby reducing the risk of chipping and premature failure. In the manufacturing processes thereof, the hardened ceramic green body (2) made by wet-forming technique has more homogenous microstructure and less particle packing defects than the dry-pressed blanks and partially sintered blanks. Furthermore, higher surface smoothness can be obtained by milling unsintered hardened ceramic green body than by milling partially sintered blanks. The dental all-ceramic restoration has a high degree of surface finish, and can be directly used without polishing, veneering or glazing.

The method is used for making a dental prosthesis or for the adaptation of an existing dental prosthesis for the inclusion in and attachment to existing residual dentition and/or at least one implant. Here, individual teeth and/or implants and/or the remains thereof form the anchor elements for anchoring the dental prosthesis. First, an imprint of the actual condition of the jaw of the patient occurs, from which a master model and a working model are molded. Then, the working model is adjustably fixed in a milling base and aligned with respect to the insertion direction in a milling machine or parallelometer. Next, adhesion surfaces (2) made from wax in the manner of wide-area brackets, an adhesive bridge or the like are molded onto the molded anchor elements (1). Then a molded connecting part (3) with a permanently attached parallelization pin (4) and/or retention anchor element is waxed thereon after successful alignment with the insertion direction by means of the parallelization pins (4). Subsequently either the teeth (7) forming the dental prosthesis, the cast-model framework (8) and further necessary parts are modeled in wax, or the already an existing dental prosthesis are modeled on. Finally the model is provided with injection molding passages (9), and for this purpose each of the elements is worked on individually. Then, the model is embedded and boiled out for removing the wax, and that finally after insertion of the interchangeable matrix (duplicating matrix) into the molded connecting part (3) and surface treatment of the mold inner surfaces and the plaster mold, the mold is removed, followed by the removal of the dental prosthesis.

A set of artificial teeth for a denture comprises a maxillary unit and a mandibular unit. When set up in lingualised occlusion or balanced occlusion, at least one of following occurs: the palatal cusp (1a) of the maxillary posterior tooth (7a) fits into the distal fossa (1b) of the mandibular posterior tooth (8a); the palatal cusp (2a) of the maxillary posterior tooth (7b) fits into the distal fossa (2b) of the mandibular posterior tooth (8b); the mesial palatal cusp (3a) of the maxillary posterior tooth (7c) fits into the central fossa (3b) of the mandibular posterior tooth (8c); the distal palatal cusp (4a) of the maxillary posterior tooth (7c) fits onto the marginal ridge (4b) of the mandibular posterior tooth (8c); and the mesial palatal cusp (5a) of the maxillary posterior tooth (7d) fits into the central fossa (5b) of the mandibular posterior tooth (8d).

An orthodontic wax dispenser is described herein. For example, certain embodiments of the present disclosure relate to a pocket-sized orthodontic wax dispenser that has an internal storage compartment for orthodontic wax, a press mechanism (e.g., a threaded piston) to compress the stored wax through an extrusion aperture, and optionally a lid or cover, which may double as a wax cutting mechanism.

A method including modifying a known upper denture to form a final upper denture by a series of steps which may include making holes in a gums section made of a first material of the known upper denture, cutting away a palate section, and applying a gold and silicon mixture to make a new palate section, to insert into the holes in the gums section, and to cover the first material. The method may also include modifying a known lower denture to form a final lower denture by a series of steps which may include making holes in a gums section made of a first material of the known lower denture, and applying a gold and silicon mixture to insert into the holes, and to cover the first material. The first material may be nylon.
