Clinical, radiographical, and histological evaluation of porous rooted polymethylmethacrylate dental implants.
Forty-three porous rooted polymethylmethacrylate (PMMA) dental implants were inserted into twenty-four dogs. Successful implants were maintained for up to three years. Histological sections with the implants in situ of implants revealed a soft tissue-implant interface similar to natural teeth. Bone and fibrous tissue ingrowth into the pores attached the implant to the bone. Failures were attributed to mechanical weakness of the implant, thin buccal cortical bone, and excessive implant-gingiva interface.
