The histological findings and histomorphometrical analyses of peri-implant tissues from nine functionally loaded dental implants from an adult cadaver were analyzed. Despite the presence of peri-implant bone loss, all implants were found to have a high degree of osseointegration, with the bone-implant contact (BIC) ranging from 69% to 88%. The mean value of the BIC was 83.2 ± 4.3% (range: 76.5 - 87.7%) for the maxillary implants and 74.4 ± 7.1% (range: 69.4 - 84.9%) for the mandibular implants. The BIC was comparable for maxillary and mandibular implants. 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.
