摘要
目的:探讨后牙重度牙周牙髓联合病变再植术双侧联冠式夹板固定治疗松动牙齿的方法和治疗效果。方法:选择由牙周炎症引起的牙周牙髓联合病变患者,牙槽骨垂直或角形吸收,牙齿松动>Ⅱ°。在拔除患牙前预先用自凝树脂制作双侧后牙联冠式夹板,长度4～5牙位,在完全凝固前取出夹板并修整,使夹板合面厚度保留1～2mm,修整颊舌侧颈缘位于龈缘的上方,形成树脂夹板联冠。将患牙拔出后体外根管充填,清除牙槽窝病变组织,并于30分钟内重新植入牙槽窝内,双侧联冠夹板固定。结果:共治疗后牙牙周牙髓联合病变患者12例14颗患牙,1个月后拆除固定夹板,患牙全部得以保留,无继发龋及颞颌关节弹响、疼痛等不适,术后1年复查,牙槽骨恢复良好,总有效率为100%。结论:再植术治疗后牙晚期牙周牙髓联合病变是可行的,患牙得以较好的保留;双侧牙周夹板是固定松动患牙的有效方法,该固定方法效果好,简便易行。
Objective：To explore efficacy of the bilateral periodontal splint after the posterior teeth replantation to severe periodontal endodontie disease. Methods ： inclusion criteria：The patients of severe periodontal endo dontic disease, whose alveolar bone was absorbed vertically or obliquely, and tooth mobility 〉 Ⅱ°. Before extracting ill teeth, preproduetiing bilateral periodontal splint with self - curing resin, the posterior teeth column connected crown type splint （length of 4 - 5 teeth ）, which was repaired before completely solidifing. The ill teeth were extracted, root canal filled, and replanted into alveolar fossa in 30min. bilateral periodontal splint were carried out. Results ： all of cureing posterior teeth periodontal endodontic disease adds to 14 teeth of 12 patients, demolishing stabilization splint, all ill teeth be-ing remained,No secondary caries and Temporomandibular joint snapping, pain and other discomfort occur, Reviewing good recovery of alveolar bone after one year, the total effective rate was 100%. Conclusion： methods of replantation of teeth for curing severe periodontal endodontic disease is feasible, teeth can be retained better, Bilateral periodontal splint for fixing loose teeth is an effective and easy way.
