摘要
目的 使用离体牙进行体外实验,对比数字化导板和超声辅助 2 种纤维桩拆除方式用于磨牙纤维桩拆除的优缺点.方法 将12 颗人类离体磨牙随机分为导板组和超声组,进行根管治疗及纤维桩修复,分别采用导板与超声器械进行纤维桩拆除.比较两组拆桩时间及牙体组织破坏程度.结果 超声组操作时间每颗牙为(11.14±1.62)min,导板组操作时间每颗牙为(5.40±0.90)min.超声组时间明显长于导板组,牙体组织冠部破坏程度也明显高于导板组.结论 在导板支持下拆除纤维桩能够缩短临床操作时间,降低技术敏感性,尽可能保留剩余牙体组织.
Abstract
Objective To compare the advantages and disadvantages of two fiber post removal methods,guide-supported and ultra-sound assisted,for the removal of fiber posts in molars using in vitro experiments.Methods Twelve human extracted molars were ran-domly divided into a guide group and an ultrasound group for root canal treatment and fiber post restoration.The fiber posts were re-moved using digital guide and ultrasound instruments,respectively.The time of removal of fiber post and the degree of tooth tissue dam-age was compared between two groups.Results The operation time for each tooth in the ultrasound group was(11.14±1.62)minutes,while that in the guide group was(5.40±0.90)minutes.The ultrasound group had a significantly longer duration than the guide group,and the degree of crown damage to dental tissue was also significantly higher than that of the guide group.Conclusion Removing fiber posts with the support of guide can shorten clinical operation time,reduce technical sensitivity,and preserve remaining dental tissue as much as possible.
