The purpose of this study was to assess whether fixed splinting aided in the reduction of posterior tooth mobility during initial therapy. A "split-mouth" approach was used in order to compare splinted segments with similar unsplinted segments. Seven patients were selected, all of whom demonstrated chronic destructive periodontitis and mobile teeth. Initial therapy, consisting of oral hygiene instruction, root curettage and occlusal adjustment, was performed over a 2-week period. At the time of initial therapy, teeth in contralateral segments were splinted with an intracoronal wire-and-acrylic splint. Tooth mobility and gingival inflammation were recorded in all four segments every 3 weeks for a 15-week monitoring period following initial therapy. The splints were removed before each data recording session and then replaced and the occlusion refined. Prophylaxis and oral hygiene instruction were repeated every second week throughout the monitoring period. The reduction in the mobility of teeth splinted during the entire therapy period did not differ from the reduction observed in the unsplinted segments. The reduction in tooth mobility observed in both the splinted and unsplinted segments over the 17-week period can be attributed to the improved occlusal relationships and reduction in inflammation.
本研究的目的是评估在初始治疗期间，固定夹板是否有助于减少后牙的松动。采用“分口”方法，以便将夹板固定的节段与类似的未夹板固定的节段进行比较。选择了7名患者，他们均表现出慢性破坏性牙周炎和牙齿松动。在2周的时间内进行了包括口腔卫生指导、牙根刮治和咬合调整在内的初始治疗。在初始治疗时，对侧节段的牙齿用冠内钢丝-丙烯酸酯夹板固定。在初始治疗后的15周监测期内，每3周记录一次所有四个节段的牙齿松动和牙龈炎症情况。在每次数据记录前取下夹板，然后重新安装并调整咬合。在整个监测期内，每隔一周重复进行预防和口腔卫生指导。在整个治疗期间，夹板固定牙齿的松动减少情况与未夹板固定节段观察到的减少情况没有差异。在17周期间，夹板固定和未夹板固定节段中观察到的牙齿松动减少可归因于咬合关系改善和炎症减轻。
