OSSEOINTEGRATION OF SUBPERIOSTEAL IMPLANT VIA GUIDED TISSUE REGENERATION - A PILOT-STUDY

The principle of guided tissue regeneration was applied in an attempt to generate bone to cover a subperiosteal implant. Titanium frame work s, casted on individual impressions of the anterior surface of the tib ia of 4 Copenhagen White rabbits, were stabilized to the tibia by micr oscrews, and half of them were covered by an expanded polytetrafluoroe thylene augmentation membrane. The observation period was 12 weeks. Gu ided bone regeneration partly covering the implants was seen at all ex perimental sides; on the control sides the implants were mainly embedd ed in fibrous tissue. Studies are in progress with the aim of reducing marked marrow space formation observed in all the regenerated areas.
