Pa. Fugazzotto, BONE REGENERATION OVER A POORLY-POSITIONED IMPLANT TO CORRECT AN AESTHETIC DEFORMITY - A CASE-REPORT, Journal of periodontology, 64(11), 1993, pp. 1088-1091
GUIDED TISSUE REGENERATION WAS EMPLOYED to effect regeneration of a di
sfigured edentulous ridge, with a poorly positioned implant in place.
Demineralized freeze dried bone and an expanded polytetrafluoroethylen
e membrane were utilized and resulted in growth of new, bone-like mate
rial in both a bucco-lingual and apico-occlusal dimension, totally sub
merging the unusable implant.
