Bone regeneration adjacent to titanium dental implants using guided tissue regeneration: a report of two cases.

TLDR

Guided tissue regeneration was used to regenerate alveolar bone alongside titanium dental implants. A Teflon membrane was placed over a newly inserted implant to achieve osseointegration, and in a second case it was used to augment a resorbed ridge, creating adequate bone for implant placement. The membranes prevented non‑bone cell repopulation and showed that guided tissue regeneration can open new avenues for reconstructive bone surgery.

Abstract

The biologic principle of guided tissue regeneration was applied to regenerate alveolar bone in conjunction with the placement of titanium dental implants. In one case, complete osseointegration of an implant was achieved by the placement of a Teflon membrane over an implant that had been inserted into an alveolus immediately following tooth extraction. In a second case, the same biologic principle was used to increase the volume (height and width) of a resorbed, edentulous alveolar ridge to provide adequate bone dimensions for implant installation. In both cases, the membranes appear to have prevented the repopulation of the wound area by cells other than those derived from surrounding bone tissue. These two different applications of the principle of guided tissue regeneration open new avenues for reconstructive osseous surgery.
