All—on—4种植即刻修复技术对牙列缺失患者的临床效果分析 　　[摘要] 目的 评价“All-on-4”即刻种植修复技术对牙列缺失患者的临床效果及探讨其技术要点。 方法 选择2010年2月～2010年11月在杭州口腔医院收治的行“All-on-4”即刻修复治疗的患者25例，种植体植入当天行即刻固定义齿修复，观察种植边缘骨吸收情况，患者满意度，追综种植体的存留率。 结果 ①120枚种植体中，至最后一次复查共8枚种植体脱落，其余112种植体行使功能良好，复查临床稳定，种植体存留率为93.3%。②倾斜种植体54例，边缘骨吸收量0.32～1.65 mm，平均（0.98±0.25）mm；轴向种植体58例，边缘骨吸收量0.21～1.49 mm，平均（0.94±0.19）mm，两者边缘骨吸收量差异无统计学意义（P 0.05）。上颌种植体56例，边缘骨吸收量0.71～1.69 mm，平均（0.98±0.24）mm；下颌种植体56例，边缘骨吸收量0.19～1.53 mm，平均（0.94±0.27）mm，两者边缘骨吸收量差异无统计学意义（P 0.05）。③非常满意者占96%（24/25），一般占4%（1/25），无不满意者。 结论 “All-on-4”即刻种植修复技术对牙列缺失患者的临床效果好，满意度高，远期效果需要进一步观察。 　　[关键词] 即刻修复；种植；All-on-4 　　[中图分类号] R783 [文献标识码] A [文章编号] 1673-7210（2013）11（a）-0073-03 　　Analysis of clinical effect on “All-on-4” implant immediate recovery technology in patients with teeth missing 　　HUANG Zhen LIU Min 　　Department of Implant Center， Hangzhou Stomatology Hospital， Zhejiang Province， Hangzhou 310009， China 　　[Abstract] Objective To evaluate the clinical effect on “All-on-4” implant immediate recovery technology in patients with teeth missing. Methods 25 patients treated with “All-on-4” implant immediate recovery technology in Hangzhou Stomatology Hospital from February 2010 to November 2010 were selected. The implant-supported fixed complete-arch all-acrylic prostheses were delivery on the operation day. Items included marginal bone resorption， the satisfaction of patients， survival of the implants were observed. Results ①8 implants were lost in the 120 cases， the giving survival rate of 93.8%. ②The tilt implants were 54 cases， marginal bone resorption was 0.32-1.65 mm，the average was （0.98±0.25） mm； the axial implants were 58 cases， marginal bone resorption was 0.21-1.49 mm， the average was （0.94±0.19） mm； the difference of marginal bone resorption was not statistically significant （P 0.05）. Maxillary implants were 56 cases， marginal bone resorption was 0.71-1.69 mm， the average was （0.98±0.24） mm. Mandibular implant were 56 cases， marginal bone resorption was 0.19-1.53 mm， the av
