【摘要】：目的评价切削纯钛嵌体冠修复短冠隐裂磨牙的临床效果。方法将64颗短冠隐裂磨牙随机分为A组、B组。A组采用全冠修复,B组采用切削纯钛嵌体冠修复,治疗后每年复查1次,连续观察2年,比较2组的修复成功率。结果修复后1年,2组成功率差异无统计学意义(93.8%vs 100.0%,χ2=2.064,P0.05),修复后2年,切削纯钛嵌体冠修复短冠隐裂磨牙成功率(96.9%)高于全冠组(68.8%),差异有统计学意义(χ2=8.892,P0.01)。将全冠组失败病例改用切削纯钛嵌体冠修复后,固位良好,未脱落。结论切削纯钛嵌体冠有效提高了短冠隐裂磨牙修复时的固位。

Methods 64 short crown occlusal molars were randomly divided into group A (group A) and group B (group B). Group A was repaired with full crown and group B was repaired with cut titanium inlay crown. after treatment, 64 short crown occlusal molars were randomly divided into group A and group B. the success rates of group A and group B were compared.
