摘要
目的观察外伤前牙冠延长术后用玻璃纤维桩核冠修复的疗效及相关问题。方法对26颗前牙外伤后断端平龈缘或位于龈下3mm以内的患牙施以冠延长术,即翻瓣术联合牙槽骨修整术,于4～6周后以纤维桩核冠修复。3个月、6个月、1a后复查,检查修复体边缘、固位情况、牙龈以及牙周组织健康状况等。结果在修复3个月后复查时,优秀20颗(76.92%),良好6颗(23.08%)。修复6个月后复查,优秀20(76.92%),良好5颗(19.23%),失败1颗(3.85%)(龈红肿,有牙周袋形成)。修复1a后复查,优秀19颗(73.08%),良好6颗(23.08%),失败1颗(3.85%)(牙槽骨吸收较明显,牙松动,探及>4mm牙周袋),修复成功率(优秀+良好)为96.16%。结论对于外伤后牙根断面平龈缘甚至在龈下的前牙,采用冠延长术加纤维桩核冠仍可获得较为满意的治疗效果。
Objective To observe the curative effect of the glass fiber post on fractured anterior teeth after a crown lengthened surgery. Methods 26 fractured anterior teeth received fiber post restorations in 4 to 6 weeks after a full crown lengthened surgery. The restoratiofis underwent a check in 3, 6 months and lyear respectively. Results Statistics showed that, among the restorations of the selected 26 fractured anterior teeth, 20, 20 and 19 were excellent when checked in 3, 6 months and 1 year respectively; 6 and 5 were good with 1 failure when checked in 6 months and 1 year respectively and 19 excellent, 6 good with 1 failure when checked in 1 year. Conclusion Fiber post and crown system are reliable for fractured anterior teeth after crown lengthened surgery.
