Abstract

Histomorphometric analyses were used to determine quantitatively the patterns of bony ingrowth that resulted from the placement of porous-surfaced dental implants. Twenty-one implants were placed in the mandibles of rhesus monkeys for up to 74 months by utilizing a two-stage approach. Quantitative histopathological evaluations were made using ground section microscopy. Bone remodeling and ingrowth from adjacent cortical bone and medullary trabeculae resulted in stable implant roots. Quantitative histomorphometric analyses revealed that approximately 60% of the available internal pores of the implants were occupied by bone. No fibrous connective tissue ingrowth or encapsulation was observed in the implant crypts.
