【摘要】 目的:介绍一种针对下前牙的改良松牙固定术,分析常规和改良下前牙松牙固定术的长期疗效。方法:回顾性分析80例行下前牙松牙固定患者的临床资料,记录固定患牙0、3、6、12个月的牙周、邻面龋以及牙周夹板的修理情况。结果:80例下前牙松牙固定患者,54例行常规松牙固定术,26例行改良松牙固定术,平均观察(4.85±3.14)年,患牙牙周状况改善明显,期间3例因反复炎症拔除单颗下前牙后行改良松牙固定术。结论:松牙固定术是解决下前牙松动,长期保存患牙的有效方法。改良松牙固定术为拔除单颗预后无望下前牙后,提供了一种新的修复选择。更多还原

【Abstract】 Objective: To introduce a modified splint method for lower anterior teeth, and analyze the long-term effect of conventional and modified splints in periodontitis patients. Methods: Eighty patients involving lower anterior teeth splinting were retrospectively accessed. The periodontal and proximal caries conditions of splinted teeth in 0, 3, 6, and 12 months and the repair of splint were recorded. Results: Eighty patients were followed over(4.85±3.14)(range: 1.0-8.5) years. The periodontal condition of the affected teeth improved significantly. During this period, 3 patients underwent modified splint after extracting a single lower anterior tooth due to repeated inflammation. Conclusion: Fiber-reinforced composites splint is an effective method to fix the loose lower anterior teeth and preserve the affected teeth for a long time. The modified splint provides a new restoration choice for the extraction of a single lower anterior tooth with poor prognosis.更多还原
