Biomechanical evaluation of calcium phosphate coated implants with a mechano-biologically affinity for adjacent bone.

目前尚不清楚TNTZ是否有足够的能力在牙科领域形成骨整合。此外，射频磁控溅射对TNTZ植入物的表面改性效果尚不清楚。为了从生物力学的角度证实这些行为，用市售纯钛(CpTi)和TNTZ制作了圆柱形种植体。本研究表明，TNTZ种植体有足够的能力形成与cpTi基本相同的骨结合，通过射频磁控溅射系统制备的ACP表面改性可以提高TNTZ种植体的骨结合程度，尤其是在种植的后期。

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.
