摘要： A dental implant fixture intended for installation in maxillary and mandibular posterior regions where bone is cancellous internally ant cortical externally characterized by labial and lingual cortical plates bounding a relatively large body of cancellous bone. The body of the implant fixture has a width dimension that is substantially the same as the distance between the labial and lingual cortical plates in the site of installation When installed in that site the implant fixture makes bone-to-implant contact with both of the plates simultaneously The length of this implant fixture is limited so that when installed it does not make contact with the mandibular canal or the sinus cavities.

摘要： A driver for screws, bolts and the like which have a socket for receiving the bit of a driver, in which a tapered holding section between the bit and the shaft of the driver serves to hold an article by frictional engagement with the opening edge of the socket when the bit is engaged in the socket for turning the article. The bit is shorter than the depth of the socket, and the holding section expands sufficiently away from the bit so as to make frictional contact with the edge of the socket when the bit is engaged in the socket.

摘要： An alignment corrector for a dental implant which is axially misaligned relative to a desired axis has a base member that is removably attachable to the implant with reproducible orientation around the axis of the implant and a corrector member providing a receiver to support a prosthesis on a support that is correctly aligned relative to the desired axis. The angular difference between the misaligned axis and the desired axis is fixed between the two members in a variety of structures.

摘要： A set of dental impression components that may be used for either pick-up type (open tray) or transfer type (closed tray) impression molding techniques. The components are used with an impression material to fabricate a model at a site in a jawbone where an implant has been osseointegrated. The impression components include an impression coping having an outer surface with its bottom end configured to reside below the gingiva surrounding the implant. A passage exists through the impression coping which accepts a first means for attaching the impression coping to the implant for use in a pick-up type impression application. The passage also accepts a second means for attaching the impression coping to the implant for use in a transfer type impression application.

摘要： Dental restoration components for use to make a replacement tooth which substantially mimics the emergence profile of a natural tooth comprising two parts, one being a core adapted for fixation subgingivally in the site of the natural tooth, and the other being an emergence-profiler guide which fits on the core and shapes the overlying gingiva to the desired emergence profile. Two sets of the components may be provided, one for use as a healing abutment, and the other for use as an impression coping.

摘要： A dental component attaches to an implant implanted in living jawbone having overlying gingiva. The implant has an apical end embedded within the jawbone and a gingival end near an interface of the gingiva and the jawbone. The dental component comprises a body having a lower region, a gingival region, and a supragingival region. The lower region has an end surface to engage the gingival end of the implant. The gingival region extends through the gingiva and has an outer surface for forming and maintaining an aperture in the gingiva that exposes the gingival end of the implant. The supragingival region has a top surface projecting above the gingiva. The dental component includes a bore for receiving a healing element and for receiving an impression element. The healing element includes a fastener the body to the implant so as to allow the gingiva to heal around the body for an extended period of time thereby forming the aperture. The impression element includes an upper segment extending above the supragingival region for receiving impression material and a lower segment securing the body to the implant. Consequently, the dental component serves as part of both a gingival healing component and an impression component.

摘要： A bone mill for preparing the second-stage opening in crestal bone surrounding the gingival surface of a dental implant in a jawbone is tubular in form and has teeth with a negative rake on an end surface and the adjacent side surface for forming a shaped opening to the implant. The side surface of the mill near the end surface is tapered to the desired shape of the opening. A guide pin fixed in the implant mates with an opening in the bone mill to center the mill relative to the implant.

摘要： An infection-blocking dental implant in which a threaded portion which contacts bone is roughened except for up to three threads which may be exposed by bone recession after implantation, which have a smooth surface. Preferably, the implant is of titanium or titanium alloy and the threaded portion is roughened by a two-step acid treatment.

摘要： A dental implant fixture intended for installation in maxillary and mandibular posterior regions where bone is cancellous internally and cortical externally characterized by buccal and lingual cortical plates bounding a relatively large body of cancellous bone. The body of the implant fixture has a width dimension that is substantially the same as the distance between the buccal and lingual cortical plates in the site of installation and has a stop flange of substantially the same width at its gingival end. When the implant is installed in that site the stop flange makes bone-to-implant contact with the coronal bone which joins the plates. The length of this implant fixture is limited so that when so installed it does not make contact with the mandibular canal or the sinus cavity.

摘要： Dental implant fixtures having external diameters less than 3.0 mm., and external threads which are deeper at the apical end of the fixture than elsewhere are described. The deeper threads near the apical end serve to pull the fixture into a prepared bore in the patient's jawbone. There results a firm close contact between the fixture and the host bone to promote osseointegration. Ultra-slim implant fixtures are provided which can be used in thin sections of human jawbone where dental implants were previously contra-indicated.
