多种骨移植材料(如各种金属、羟基磷灰石、陶瓷等)一直被用于下颌骨的再造。理想的种植材料应具有在骨内有牢固的锚着力,种植体和骨能直接接触以及稳固的固定。钛及钛合金在体内外的研究均发现有良好的生物相容性。然而,也有报告认为钛及其钛合金对某些患者来说并不是理想的生物相容性材料。作者在 A variety of bone graft materials (such as various metals, hydroxyapatite, ceramics, etc.) have been used for mandibular reconstruction. The ideal implant material should have strong anchoring in the bone, direct contact between implant and bone, and firm fixation. Titanium and titanium alloys have been found to have good biocompatibility both in vitro and in vivo. However, there are also reports that titanium and its titanium alloys are not ideal biocompatible materials for some patients. The author is here
