[Osseointegrated implants. Clinical cases and light and electron microscope study]

Titanium osseointegrated implants have been placed in maxilaries of partially edentulous patients. After a follow-up of 5 to 6 months, a clinical and radiographical evaluation was made in order to determine the osseointegration obtained. In two of these cases, the gingival tissue in contact with the implants was studied under a light and transmission electron microscope. The results indicated a high percentage of implants were osseointegrated (99.72%), and the microscopical analysis showed a tissular reaction denoting biocompatibility with the implants.
