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

Analysis of clinical effect on “All-on-4” implant immediate recovery technology in patients with teeth missing

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-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0．32～1．65mm，平均（0．98＋0．25）mm；轴向种植体58例，边缘骨吸收量0．21～1．49mm，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0．71～1．69mm，平均（0．98±0．24）mm；下颌种植体56例，边缘骨吸收量0．19～1．53mm，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），-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。

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 （1）8 implants were lost in the 120 cases, the giving survival rate of 93.8%. （2）The 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 average was （0.94±0.27） mm, the difference of marginal bone resorption was not statistically significant （P 〉 0.05）. （3）The percent of great satisfaction was 96% （24/25）, the percent of common situation was 4% （1/25）; no dissatisfaction was found. Conclusion The clinical effect of All-on-4 immediate function for edentulous patients is satisfactory, satisfaction of the patient is high. It is right to give further study to determine the long-term result of the technology.
