Implant Placement after Sinus Augmentation with Hydroxyapatite Bone Graft and Platelet Rich Fibrin Membrane Closure: A Report of 2 Cases

Long standing period of edentulousnes, coupled with increased antral pneumatization in the maxillary posterior regionmakes the alveolar ridge unsuitable for implant placement due to insufficient bone height, density and volume. Maxillary sinus augmentation is a surgical procedure which aims to increase the amount of bone in the posterior maxilla in the area of the premolar and molar teeth, by lifting the lower Schneiderian membrane and placing a bone graft. The case reports presented here aims at the immediate placement of the implant after a sinus augmentation surgery with hydroxyapatite bone graft and platelet rich fibrin (PRF) membrane closure.
