It is not clear yet whether TNTZ has sufficient ability to form osseointegration in the dental field. In addition, the effectiveness of surface modification by radiofrequency (RF)magnetron sputtering on TNTZ implants is unclear. To confirm these behaviors from the biomechanical viewpoint, cylindrical implants made from commercially available pure titanium (cpTi)and TNTZ were prepared. The present study suggests that TNTZ implant has sufficient ability to form osseointegration approximately the same as that of cpTi, and the degree of osseointegration of TNTZ implant is improved by surface modification of ACP prepared by RF magnetron sputtering system, especially in the late stage of implantation.
