摘要 目的:分析桩核冠修复失败的原因,探讨临床上引起修复失败的可能因素,选择最适合患者的桩核冠修复系统。方法:收集因桩核冠修复失败前来安阳市口腔医院修复科就诊的病例149例(176颗牙),常规门诊检查、拍X光片及询问病史,记录桩核冠修复失败常见的临床表现并分析原因。结果:176颗牙中桩核松脱106颗,占60.2%;牙体劈裂47颗,占26.7%;冠松脱或损坏18颗,占10.2%;桩折5颗,占2.8%。结论:桩核冠修复失败的主要临床表现为桩核松脱、牙体劈裂、冠脱落或损坏和桩折。其影响因素有桩核的设计、患者本身的条件、粘接剂、技工的制作及患者的咬合习惯等。医生应严格掌握适应证,注意正确的临床操作和精确的技工制作,以减少失败的发生。
