Bone Reactions to Hydroxyapatite-Coated Dental Implants in Humans: Histologic Study Using SEM, Light Microscopy, and Laser Scanning Microscopy

Adriano Piattelli, MD/Paolo Trisi, DDS/Mario Emanuelli, MD

Two hydroxyapatite-coated IMZ implants, extracted for psychiatric reasons, were prepared using a cutting-grinding system and studied with scanning electron microscopy and laser scanning microscopy. The examination showed tissue integration with a very intimate bone-implant contact. Laser scanning showed the presence of a layer of dark staining material, resembling a reversal line of bone tissue, at the bone-implant interface, which could be the result of a film of organic material deposited on the bone and hydroxyapatite surfaces. (INT J ORAL MAXILLOFAC IMPLANTS 1993;8:6974.)

Key words: bone-implant interface, hydroxyapatite, hydroxyapatite-coated implants, laser scanning microscope
