Further studies on tissue ingrowth into intrabony porous ceramic implants.
Porous ceramic Al2O3 implants with pore size of 100-750 micrometers were placed intrabony in the maxillary tuberosity of eight Cercopithecus monkeys. All implants healed primarily. Vital staining of mineralizing tissue was attempted using intravenous injections of tetracycline and calcein. The implants were retrieved after implantation times of 3, 5, 10, 11 and 12 months. Infiltration of fibrous tissue and bone was found in all impants, but the amounts of tissue observed were not significantly greater after the longest implantation times as compared to the 3- and 5-month results.
