Ridge Preservation with Beta-Tri-Calcium Phosphate versus Composite Autogenous Tooth Graft and Beta –Tri-Calcium Phosphate

Abstract

In the current times, where implant placement is the most favored option for replacement of a missing tooth, preservation of alveolar ridge is of vital importance. Following tooth extraction, dimensional changes of the residual alveolar ridge are inevitable. Thus, to maintain the bone volume, placement of various graft materials inside freshly extracted socket is advocated by multiple studies as a "ridge preservation technique." The aim of the present study was to compare three months post-extraction augmented ridge using Beta-tricalcium-phosphate bone graft versus a composite of autogenous tooth graft and Beta-tricalcium-phosphate bone graft both loaded in bioresorbable collagen membrane. This comparison was done clinically, histologically and radiographically. Clinical parameters included; vertical bone height and bone width that were recorded at baseline and at three months after extraction. Moreover, histomorphometric parameters included; area fraction of osteoid and mature bone three months after extraction by histomorphometric analysis. Radiographic parameters included superimposition of baseline CBCT and another one done three months after extraction with subsequent measurement of bone height, bone width and bone d
