238颗Branemark种植体植入48名下颌全牙列缺失患者的颌骨内 ,完成固定可卸式修复体46件 ,临床观察30～48个月 ,修复后2年累积成功率为97.4% ,修复体稳定率为100% ,种植失败多数发生在种植早期 ,其主要原因为骨质疏松。
Forty-eight Branemark implants were implanted in the jaws of 48 patients with mandibular total dentition, 46 of them were fixed and disassembled. The clinical observation ranged from 30 to 48 months. The cumulative success rate at 2 years after repair was 97.4% The body stability rate was 100%. Most of the planting failures occurred in the early planting stage. The main reason for this was osteoporosis.
