Abstract
Contour Augmentation after Guided Bone Regeneration with Porous Titanium Granules: A Clinical, Histologic and Histomorphometric Evaluation
Highlights
Tooth extraction causes inevitable changes in the supporting structures, which may lead to complications for dental implant placement [1]
Porous titanium granules (PTG) were first introduced by Bystedt et al [17] as an osteoconductive material for bone grafting in sinus floor augmentation surgery [17]
Wohlfahrt et al [21] reported that clinical attachment level and gingival recession were not significantly different from the baseline values 12 months after treatment of grade II furcal defects of mandibular molars with PTG, but pocket depth and gingival index significantly decreased after treatment and bleeding on probing (BOP) remained unchanged [14]
Summary
Tooth extraction causes inevitable changes in the supporting structures, which may lead to complications for dental implant placement [1]. Since the 1960s, many studies have been conducted to assess the loss of hard and soft tissues after tooth extraction, and innumerable efforts have been made to prevent or minimize bone loss [2]. Different methods have been suggested to preserve and reconstruct bone volume and prevent alveolar ridge resorption following traumatic events such as tooth extraction. The guided bone regeneration (GBR) technique has presented promising results in repairing bone defects. Autogenous bone grafts are considered the gold standard for GBR, due to their osteoconductive, osteoinductive, and osteogenic properties [3,4]. Despite their high efficacy for bone reconstruction, the need for Modern Research in Dentistry
