A specially designed, TiO2-blasted titanium fixture, partially conical and microthreaded, the Astra Tech Fixture ST, was used for rehabilitation of partial edentulism in the posterior mandible. Superior to the mandibular canal 25 fixtures were placed in 10 patients. Fixed metal-ceramic bridges were then performed. After 1-year follow-up, all bridges were found to be clinically stable. The implant survival rate was 100% and the mean marginal bone resorption was 0.05 +/- 0.11 mm.
一种专门设计的、经二氧化钛喷砂处理的钛制种植体，部分呈圆锥形且有微螺纹，即Astra Tech种植体ST，被用于下颌后牙部分牙列缺失的修复。在10名患者的下颌管上方植入了25颗种植体。随后进行了固定金属烤瓷桥修复。经过1年的随访，发现所有桥体在临床上均稳定。种植体的存留率为100%，平均边缘骨吸收为0.05±0.11毫米。
