Reconstruction of alveolar defects before implant placement

Guided bone regeneration and bone grafting have been used to reconstruct defective alveolar ridges in preparation for implant placement. This phase of implant treatment is critical to a successful overall result. Remarkable advances that have occurred in techniques and materials enable us to place and restore implants in cases where previously it was not feasible. Three case reports are presented to illustrate successful management of different alveolar defects.
