Enhancement of the damaged edentulous ridge to receive dental implants: a combination of allograft and the GORE-TEX membrane.

A severely damaged edentulous ridge frequently obviates the placement of dental implants or results in placing them at an angle that compromises the prosthetic restoration. This paper demonstrates the repair of severely resorbed edentulous ridges by a combination of bone allografting and the placement of a barrier membrane. The damaged edentulous ridge is treated first in this two-stage process. The implants are then installed at a second surgery.
