Guided bone regeneration via an osteopromotive barrier is indicated in diff
erent alveolar bone deficiencies and in periimplant bone destruction around
pathologically denuded exposed implants. Regeneration of the osseous volum
e is determined by understanding the biologic behavior response of hard and
soft tissues in guided tissue regeneration procedures. Consequently, a met
iculous surgical approach is mandatory to preserve wound healing cascades a
nd tissue stability. However, hard tissue augmentation in the nonsupported
coronal direction has been unpredictable. A case report is presented in whi
ch a severely defected ridge around a pathologically exposed functional imp
lant combined with a destructive extraction site was restored and regenerat
ed. Bovine bone mineral particles (Bio-Oss) served as the graft material an
d were followed by an expanded polytetrafluoroethylene (e-PTFE) occlusive m
embrane as a bilateral regenerative tissue guide. Subsequently, 2 additiona
l implants were placed in the augmented hard tissue ridge.
