    摘要: The present invention elated to a dental prosthetics and more particularly to an improved support post having a centrally convergent shank portion for securing a dental prosthesis, such as an artificial crown, to the root of a tooth. The invention further relates to a method and a device for strengthening a tooth and a root from which the nerve has been removed and specifically to a dental post which provides centering for the forming of a bracing filler to internally reinforce the walls of pulpless roots while providing for the support of an artificial prosthesis. The invention further provides for a secondary reinforcing device surrounding the central dental post and also being capable of following the contours of the tooth root. This secondary strengthening and reinforcing element is a flexibly coiled wire of a generally helicoid shape, which also serves as a matrix for the luting of composite filler.

    摘要: An apparatus and method for creating a structure (10) with complex external and internal shapes (12 and 14) includes a unitary flexible mold of a structure (10) with complex external shapes (12). A unitary flexible male mold (24) of the interior of the structure with complex internal shapes (14) that mirror the complex external shapes (12) is created. A keying device (42) connected to the molds (16 and 24) is utilized so that the unitary flexible female mold (16) and the unitary flexible male mold (24) are maintained in a predetermined, fixed relationship (40) when pressed together.

    摘要: A method for forming a dental coping from a base material composition containing high fusing temperature metal particles and a wax binder and a filler material composition containing low fusing temperature metal particles and a wax binder wherein the two materials are molded over the surface of a die either separately or as a laminate into a shape conforming to the shape of a tooth to be restored and heat treated in a a furnace in a single heat treatment operation from a temperature to cause the high fusing temperature metal particles to form a stable porous structure of high fusing temperature metal to an elevated temperature not to exceed about 1130° C. but preferably between about 1075° C. and 1100° C. so as to melt and densify the low fusing particles into the porous structure.

    摘要: A quadrant and/or anterior shell for making a bridge or multi-tooth crown includes a plurality of integrally formed shell segments. Each shell segment corresponds to a different tooth in the respective quadrant and/or anterior region. Each shell has an occlusal surface, formed on a top wall, that replicates the occlusal surface of a natural tooth. A method of forming bridges or crowns using such shells includes selecting or sectioning off an appropriate section of the shell. The selected shell section is filled with resin. The shell section is positioned over prepared teeth, and, in the case of a bridge, also over a gap in the patient's dentition. Resin extrudes from mesio-distal sides and gingival margins of the shell section to form good proximal and gingival contacts. Once the resin has set, the resin and shell section are shaped to form the final crown or bridge.

    摘要: A fiber-reinforced composite material with graded stiffness, and method of making the same. The degree of stiffness variation may be controlled via modifications to the fabrication processes. Products with varying stiffness along their lengths are described. In one example, a dental post is fabricated from material according to the present invention which has one end with low stiffness adapted for insertion into the root of the tooth, and a high stiffness end suitable to support the restoration.

    摘要: A dental post and method for supporting a tooth replacement on a natural tooth root, has a shank with a first root engagement portion and a second tooth replacement support portion. A non-round flange is on the first portion but is adjacent the second portion. The non-round flange is received in a non-round countersink at the opening of the root canal for precluding relative rotation between the post and the root. One or more flexible flanges extend from one or both of the shank portions and the entire post is made of plastic.

    摘要: The anchorage element for a tooth suprastructure, e.g. a root canal anchor, consists of a fiber-reinforced synthetic material in which the biaxially or multiaxially extending fibers are arranged in a braided netting. Such anchorage elements provide a high flexural and torsional strength, i.e. breaking resistance, as well as a high axial flexibility.
