全冠与高嵌体修复根管治疗后牙牙体缺损的临床观察

Clinical observation of root canal treatment after tooth body defection crown Onlays

目的：观察磨牙经过根管治疗后对其运用全冠、高嵌体修复的效果。方法：选取经过某门诊完善根管治疗的磨牙240例分两组,每组120例,A组行全冠修复,B组行高嵌体修复,观察其修复的效果。结果：通过对A组120例磨牙的嵌体,B组120例磨牙全冠修复后2~5年随访观察,A组107颗修复成功,咀嚼功能恢复良好,6颗牙出现不同程度的松动,5颗出现牙龈萎缩,2颗因牙周炎拔除。B组109颗修复成功,咀嚼功能恢复良好,边缘密合,仅5颗牙出现不同程度松动,4颗出现牙龈萎缩,2颗因牙周炎拔除。结论：根管治疗后全冠修复或高嵌体修复在临床上效果无明显差异,但鉴于高嵌体磨除牙体组织少,不破坏患牙与邻牙邻接关系,不涉及牙龈组织的关系等诸多优点,临床应更多推广高嵌体。

Objective： To observe the molars after root canal treatment using crowns, onlays its effects. Methods： after my root canal therapy outpatient perfect teeth 240 cases divided into two groups, 120 cases in each group, a set of rows crowns, onlays a row repair, repair observed effects. Results： A group of 120 cases of molar inlays, group B 120 cases molar crown after 2 to 5 years of follow-up observation repair, A group of 107 successful repair, restore chewing function well, six different degrees of loose teeth, 5 gum recession occurs, two pull out due to periodontitis. Group B 109 teeth repair is successful, chewing can be a good recovery, edge seal, only five different degrees loose teeth, gum recession occurs four, two pull out due to periodontitis.Conclusion： The root canal treatment crowns or on- lays on the clinical effect was no significant difference, but given onlays wear less tooth structure removed, does not destroy the teeth adjacent relationship with adjacent teeth, gum tissue does not involve many advantages relations, which is worthy of more clinical promotion.
