Regeneration of an osseous peri-implantitis lesion.
This case report concerns the loss of osseous tissue around two hydroxyapatite (HA) Biovent implants, placed in 1993, at sites #30 and #31. The implant in site #31 was positioned with a distal angle, resulting in an ill-fitting prosthesis. This permitted bacterial colonization to set up a periimplantitis. The rough HA coating on the implants further exacerbated the resultant bone loss. In an attempt to rectify the pathology, surgical debridement, antibiotic therapy, bone grafting, and guided tissue regeneration with a barrier membrane were utilized. This case report documents a successful partial repair of osseous housing around these implants.
