Abstract
Roberto Pistilli, MD/Massimo Simion, MD, DDS/Carlo Barausse, DDS, PhD/Roberta Gasparro, DDS, PhD/Valeria Pistilli, DDS/Pierantonio Bellini, MD/Pietro Felice, MD, DDS, PhD: The aim of this retrospective study was to evaluate clinical and radiographic outcomes of guided bone regeneration (GBR) procedures in the rehabilitation of partially edentulous atrophic arches. A total of 58 patients were included with a follow-up of 3 to 7 years after loading. Data seem to indicate that GBR with nonresorbable membranes can be a good clinical choice and suggest that it could be used to vertically reconstruct no more than 6 mm of bone in the posterior mandible. However, this technique remains difficult and requires expert surgeons.
