Bone regeneration for reintegration in peri-implant destruction.

Complications and deterioration around functional osseointegrated implants stem from two major factors: bacterial-initiated disease and overloading. Peri-implant breakdown can occur during the postsurgical phase and before the reconstructive phase as a result of surgical trauma and/or predisposed compromised recipient bone site. Technical errors also potentially contribute to bone loss, which results in the loss of osseointegration. Two case reports associated with peri-implant destruction are presented. The possible etiologic factors are discussed, and an attempt to regenerate lost peri-implant tissue is demonstrated via guided bone regeneration principles using barrier membranes.
