摘要： A support post (10) for the use with a dental implant for supporting a prosthesis thereon is disclosed. The support post (10) includes an implant contacting region and a supra-gingival core section (22) which extends from the trans-tissue region for supporting a prosthesis. An interface member (26) is secured to the post at the bottom of the implant contacting region for abutment between the implant contacting region and an implant to which the post is to be secured. The interface member (26) has material properties different from those from which the post is made and compatible with those of the implant. Typically the support post is made of ceramic material while the insert is made of titanium having hardness properties no greater than that of the implant with which it is used.

摘要： A set of components are set forth which efficiently deliver a dental implant (10) to a site at which the implant is to be installed in living jawbone. The implant has a gingival end with a manipulating fitting (16), and a threaded bore (18) extending inwardly from the gingival end. The set of components includes a carrier device (12) having an upper end, a lower end, a through bore (20) extending between the lower and upper ends, and a fitting (24) for mating with the manipulating fitting of the implant. The through bore in the region adjacent to the upper end includes a non-circular socket (25) for receiving an implant/insertion tool (40) that imparts movement to the carrier device and the implant. The set of components further includes a screw (14) for attaching said carrier device to said implant. The screw has a lower threaded portion (30) for engaging the threaded bore of the implant, and a head (28) for stopping on a shoulder (22) within the through bore of the carrier device. The set may further include an impression coping (120) which attaches to the carrier, and allows the clinician to take an impression of the site immediately after installing the implant.

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).
