We examined the tissue reaction to IMZ implants with polyoxymethylene internal mobile element (POM-IME) and the other ones with titanium IME (Ti-IME). No histopathologic difference was observed between the implants with POM-IME and those with Ti-IME, except for the cervix. The gap between transmucosal implant extension (TIE) and implant body, and inflammatory reaction were observed around the cervix. These findings were very remarkable in the implant with POM-IME. In image analysis, no great difference of bone contact near the roots of implants was seen between the implants with POM-IME and those with Ti-IME.
