Histologic and histomorphometric analyses of peri-implant bone from loaded dental implants: A case report.

2 The histological findings of peri-implant tissues from nine functionally loaded dental implants from an adult cadaver were analyzed, and histomorphometric analyses were performed. Despite the presence of peri-implant bone loss, all implants were found to have a high degree of osseointegration, with the bone-to-implant contact (BIC) ranging from 69% to 88%. The mean value of the BIC was 83.2% ± 4.3% (range: 76.5% to 87.7%) for the maxillary implants and 74.4% ± 7.1% (range: 69.4% to 84.9%) for the mandibular implants. The BIC of the maxillary and mandibular implants was comparable. Relatively prominent bone remodeling and resorption with soft tissue ingrowth were observed in the vertical bony defects compared to the areas without intrabony components, which might represent the sequence of bone loss around the dental implants.
