Guided bone regeneration: results, limitations and prospects 1 February 2013

Authors: Hadi Antoun, Michel Karouni, Bouchra Sojod

The challenge in oral implantology is to obtain adequate and long-term results either on the aesthetic or functional point of view. In order to achieve this goal, bone gain before or at implant placement is needed each time we are faced with a bony defect.

Guided bone regeneration (GBR) is the most documented between bone augmentation techniques in the literature and predictability of longterm results will be analyzed in this paper. Nevertheless, as for any other techniques, GBR has some limitations and failures. Different membranes and bone substitutes used in this approach will be presented and illustrated by three clinical cases.
