Immediate Implantation of Pure Titanium Implants Into Extraction Sockets of Macaca fascicularis Part I: Clinical and Radiographic Assessment

Immediate implants have the advantages of few surgical exposures, short treatment time, and maintenance of alveolar bone height and width. The purpose of this study was to compare immediate implants with conventional implants (implants placed into ossified extraction sites) in adult monkeys. Forty-eight implants were placed and allowed to heal for a 6-month period. Following a 7-month loading period, the monkeys were sacrificed, and implant sections were evaluated histologically. Clinical and radiographic measurements showed few significant differences between immediate and control implants.
