BACKGROUND/PURPOSE: Splinting mobile teeth is a choice to improve the patient's oral comfort. The purpose of this study was to assess the survival and stability of mobile anterior mandibular teeth after splinting in patients with periodontitis undergoing supportive periodontal therapy (SPT).
Patients with splinted mobile anterior mandibular teeth were assessed retrospectively. Periodontal statuses were recorded at baseline and follow-up visits. Tooth and splint survival as well as splint repairs were recorded. Multilevel Cox regression analyses were performed to evaluate patient- and tooth-related factors that might have influenced the survival rates of splints.
Sixty-one patients, collectively having 161 splints, were followed for an average of 5.44 years. On average, probing depth (PD) of splinted teeth decreased from 4.31 mm to 2.93 mm and clinical attachment loss (CAL) decreased from 5.02 mm to 4.58 mm. Alveolar bone was stable in the follow-up period. None of the splinted teeth were extracted, The overall survival rate of the splints was 65.2%. Splints made of composite resin alone were associated with a higher risk of breakage when compared to splints composed of composite resin with mesh grid strips.
Splinting showed long-term survival and splinting combined with periodontal supportive treatment is a feasible option to maintain mobile mandibular anterior teeth.
背景/目的：固定松动牙是提高患者口腔舒适度的一种选择。本研究的目的是评估在接受牙周支持治疗（SPT）的牙周炎患者中，下颌前牙松动牙固定后的存留率和稳定性。
对下颌前牙松动牙固定的患者进行回顾性评估。在基线和随访时记录牙周状况。记录牙齿和夹板的存留情况以及夹板修复情况。进行多水平Cox回归分析，以评估可能影响夹板存留率的患者和牙齿相关因素。
61例患者共安装了161个夹板，平均随访5.44年。平均而言，固定牙的探诊深度（PD）从4.31mm降至2.93mm，临床附着丧失（CAL）从5.02mm降至4.58mm。随访期间牙槽骨稳定。所有固定牙均未拔除，夹板的总体存留率为65.2%。与由复合树脂和网格条组成的夹板相比，仅由复合树脂制成的夹板折断风险更高。
夹板固定显示出长期存留效果，夹板固定结合牙周支持治疗是维持下颌前牙松动牙的可行选择。
