【摘要】 目的:探讨钇铝石榴石晶体激光(Neodymium-doped Yttrium Aluminium Garnet,简称Nd:YAG)与二氧化锆全瓷冠联合治疗前牙不良修复体引起的牙龈增生的临床效果。方法:选择52例患者的125颗前牙,经过镍-铬合金烤瓷全冠修复后出现牙龈增生,采用Nd:YAG激光与二氧化锆全瓷冠修复,观察1年后牙龈情况。结果:125颗牙龈增生的前牙,治疗后未出现牙周组织病变及再次龈增生,美观恢复良好。结论:Nd:YAG激光与二氧化锆全瓷冠联合修复是治疗前牙不良修复体引起的牙龈增生的有效方法。更多还原

【Abstract】 Objective To investigate the clinical effect of Nd:YAG laser and zirconia crown on the anterior tooth with gingival hyperplasia following the ill fitting prosthesis used. Methods All 52 patients treated with Nd:YAG laser and zirconia crowns for 125 anterior teeth,which with gingival hyperplasia after Ni-cr porcelain teeth,observe the situation of gingival for one year. Results After one year restoration,all of the 125 zirconia crowns had no gingival hyperplasia and good apperence.Conclusion Nd:YAG laser and zirconia crown contribute to the aesthetic effect of the anterior teeth.更多还原
