Long-term evaluation of submerged and nonsubmerged ITI solid-screw titanium implants: a 10-year life table analysis of 468 implants.

Purpose: Submerged and nonsubmerged ITI solid-screw titanium implants were followed retrospectively from 1989 to 1993 and prospectively from 1994 on to analyze long-term prognosis in partially and fully edentulous patients.

Material And Methods: A total of 468 implants were consecutively inserted in 191 patients from 1989 to 1998. Two hundred twenty-eight successfully integrated fixed-restoration implants and 238 with removable restorations were restored following a healing period of 4 to 6 months (9 months in sinus floor elevation sites).

[Torque of endosseous dental screw type implants].

The success of osseous and oral implants is partially dependent on the design and on the mechanical way of insertion. The torque moments during manual and machine-insertion and the correlation between torque and design of the implants were topics of this paper. The experiments were separated in two parts using pork-ribs in vitro.
