T he present paper describes 18 consecutively‐treated non‐human primates ( Macaca mulatta ) as part of a balanced block design study of 36 animals to examine osseointegration in root‐ and plate‐form implants prepared by atraumatic preparation of bone. Clinical measurements around selected teeth and digital radiology were utilized to monitor periodontal disease and bone deposition around the unloaded implants. Once a month scaling procedures were utilized as a means of preventing further advance of periodontal disease. Results indicate that once‐monthly regimen of scaling and root planing can prevent attachment loss of natural teeth and will not interfere with the healing of either type of implant; once‐monthly scalings produce significant reduction in redness ( P <.05) and reduced probing depths ( P =.01). A second finding is that both root and blade implants show radiographie evidence of osseointegration in this primate model. The quantitative analysis demonstrates bone gain is not stabilized until 6 months after healing. The data may indicate that occlusal loading of mandibular implants at 3 months may be premature.
