The results of a research project which has been under way for the last 7 years are reported. The project has been centred around a series of animal (monkey) experiments designed to test the suitability of cylindrical titanium implants with titanium-sprayed surfaces. The following results have been obtained: 1. The bone applies itself "ankylotically" (i.e.… (More)
The development of dental implants has led to an expansion of indications and to perfection of implantation methods and implant systems. Angulation problems due to anatomic limitations, however, still remain. The indications for the use of angled Bonefit I.T.I. implants are described.
The explantation technique for the ITI F-type and Bonefit implant system is described. Although implant survival rates are high, the risk of failure must be considered. In some cases implants will have to be removed for reasons other than failure of the implant itself.
A new implant consisting of a hollow cylinder of titanium is described. It is well suited to investigate the tissue reaction to several surface textures in the animal experiment (Macaca speciosa). From a test series, for which the implants were surfaced with powdered titan (titan plasma), one was selected which had been worn for 7 months as a partial… (More)
