Abstract:

Bone implant repair for missing teeth has become one of the treatments with plenty of evidence to support. The theoretical basis of planting technology is osseointegration，the direct connection of the implant surface with the surrounding living bone. Surface characteristics of the implant material are an important factor which affects osseointegration. In recent years，researchers have modified surface properties of the implant by various methods，such as the change of the surface morphology，structure，chemical properties and/or hydrophilicity，to promote osseointegration speed. For now，promoting osseointegration by increasing the hydrophilic properties of titanium implant surfaces has become one of the main research focuses. This review focuses on improving the surface properties of titanium implants，especially the hydrophilic properties .

Key words: titanium implants, hydrophilicity, osseointegration

摘要：

骨内种植体修复缺失牙已成为具有大量证据支持的治疗方法。种植技术的理论基础是骨结合，即种植体表面与周围活骨的直接连接，种植体材料表面特性则是影响种植体骨结合生物学过程的重要影响因素 。近年来，研究者们通过各种方法修饰种植体的表面特性，如改变表面形态、结构、化学性能和亲水性等，以促进骨结合的速度。目前，通过提高钛种植体表面的亲水性能从而促进骨结合已成为研究热点之一。本文就提高钛种植体表面性能，尤其是亲水性能的研究现状进行综述。
