摘要:
Improved tensioning or pre-loading of screws (13) used to assemble dental implants (11, 12) is made possible by using screws (13) which have a coating of gold, particularly screws (13) made of palladium alloy. The increased pre-load improves the stability of the dental implant assembly (11, 12) because greater mastication forces are then required to pry apart contiguous components of the implant assembly (11, 12) and bend the screws (13).

This invention is a post and socket connector (10, 12, 20, 22, 40) having anti-rotational elements (28, 44, 58, 68) near the base of one or both parts for filling selected portions of the space between them, thereby restricting or eliminating relative rotation of the two parts around a common axis.
摘要:
The present invention relates to processes for improving the surfaces of devices to be surgically implanted in living bone, and to implant devices having the improved surfaces. A titanium body (10) which has been exposed to air has on it an oxide layer (14) of an oxide or oxides of titanium which forms naturally. The oxide layer (14) is typically of a thickness in the range of 70 Angstroms to 150 Angstroms. To render the titanium body (10) better suited for implantation, the outer surface (12) is grit blasted and then bulk etched with an etching acid to produced an etched area (16) which is free of the oxide layer (14).
摘要:
This invention is a tool for affixing a component (10) to a dental implant fixture with a screw (12) passing through the component (10) and threaded into the implant fixture, in which the tool has two parts (28, 40) telescopically inter-fitting one within the other, the outer part (28) being tubular for carrying the component (10) at one end, and the inner part (40) fitted at one end for carrying the screw (12) positioned within the component (10), whereby the component (10) and the screw (12) within it can be carried together to the implant fixture where the outer part (28) is used to hold the component (10) in place, while the inner part (40) is used to drive the screw (12) relative to the implant fixture.
摘要:
The present invention provides a healing abutment for attachment to a dental implant with marking locations thereon. The marking locations either lack or have markers that provide a binary code system for retrieving unique information about the healing abutment and the underlying implant.

摘要:
A self-tapping dental implant (10) comprises a generally cylindrical body (12) with a threaded outer surface for securing the implant to the walls of a preformed hole in a jaw bone. The cylindrical body has a plurality of longitudinal recesses (22, 24, 26, 28) formed in the threaded surface at one end, and extends longitudinally through a plurality of turns of the thread to form a self-tapping cutting edge (32, 34, 36, 38) at each interruption of the thread by one of the recesses. Each thread segment extends between a pair of adjacent recesses and diminishes in radius between the leading and trailing ends of the thread end.
摘要:
The present invention relates to a method for forming osseous tissue in any bone tissue site of reduced metabolic state, comprising implanting particles of bioactive glass in a size range of from about 200 micrometers to about 300 micrometers. The particles are made from about 40 % to about 58 % silicon dioxide, from about 10 % to about 30 % sodium oxide, from about 10 % to about 30 % calcium oxide, and up to about 10 % phosphorous pentoxide, by weight.
摘要:
The present invention provides a healing abutment for attachment to a dental implant with information markers provided thereon and a method for making the same. The implant has an apical end installed into a jawbone having overlying gingiva and a gingival end near an interface of the gingiva and the jawbone with a hexagonal boss thereon. The healing element comprises information markers for determining the orientation of said hexagonal boss, the diameter of said healing element, the height of said healing element, and the size of said implant.
