摘　　要：目的评价插销固位一体式金属桩部分冠修复牙冠短伴牙体缺损磨牙的临床效果。方法采用插销固位一体式金属桩部分冠,修复38颗临床牙冠短伴牙体缺损、颌间修复间隙不足的磨牙。修复后即刻、1年、2年、3年进行检查,从牙齿完整性、牙体有无继发龋、修复体完整性、修复体固位、修复体边缘适合性及修复体的邻接关系等进行评价。结果 38颗患牙修复后即刻、1年、2年及3年检查显示,插销固位一体式金属桩部分冠固位良好,牙体及修复体的完整性好,边缘适合性好,没有出现继发龋;有2颗出现轻度食物嵌塞,占5.3%。各项评价指标在修复后即刻、1年、2年、3年的差异均无统计学意义(P>0.05)。结论采用插销固位一体式金属桩部分冠修复临床牙冠短伴牙体缺损的磨牙,修复效果好,在临床上有一定的实用价值。Objective To evaluate the clinical effect of molar restoration with short clinical crowns and tooth defect by bolt pile retaining integrated metal pile partial crown. Methods Thiry-eight molars with short clinical crown, tooth de- fect, intermaxillary insufficient clearance were repaired by bolt fastening integrated metal pile partial crown. The crowns were examined immediately, I years, 2 years, 3 years ＇after the restoration, anti the tooth integrity, secondary caries, crown inteity, crown retention, marginal fit and adjacent relation were evaluated. Results Compare the restorations effect of 38 teeth in immediately, 1 years, 2 years and 3 years ＇after restoration, bolt fastening integrated metal pile partial crown always had excellent retention force, marginal fit, tooth integrity and crown integrity, no secondal.-y caries, and 2 cases of mild food impaction with a ratio of 5.3%. Conclusion The restoration effect of molars with short clinical crowns anti tooth defect by bolt fastening integrated metal pile partial crown is excellent and has some practical value in clinical practice.
