摘要： 目的：评价一种国产牙种植体临床应用效果。方法：按纳入标准收集32例种植修复单颗牙缺失的患者， 共植入38枚种植体，随访5年，通过临床检查及X线影像学检查，参照Albrektsson种植体成功标准，评价该牙种植体临床应用效果。结果：种植修复后，随访5年，32例患者无不适主诉，38枚种植体无松动、脱落、断裂，周围黏膜无急慢性炎症；种植体与骨组织结合良好，种植修复5年时，种植体颈部边缘骨平均吸收高度为0.63 mm （SD: 0.30; range: 0.33~0.93），5年成功率达100%。结论：该牙种植体具有良好的骨结合力和较少的颈部边缘骨吸收。

Abstract: Objective: The purpose of this paper was to evaluate the clinical efficacy and safety of ZDI dental implants. Methods: Thirty two patients with single odontoptosis who needed implant restoration were enrolled and installed by 38 ZDI dental implants. Through a 5-year follow-up, clinical examination and radiological examination, the clinical efficacy evaluation were performed according to Albrektsson's success criteria. Results: After five -year follow up, the soft tissue around implants was stable and favorable osseointegration was found by radiological examination. A mean marginal bone loss of 0.63mm (SD: 0.30; range: 0.33-0.93) in implant neck was measured. The total survival rate was 100%. Conclusions: From this clinical trial, it is concluded that the ZDI dental implants show favorable osseointegration and less marginal bone loss.

Key words: dental implant, osseointegration, marginal bone loss
