牙周炎致错位前牙的正畸牙周联合治疗

目的　对牙周炎致唇向散开的前牙经环切离断牙槽嵴顶纤维后进行正畸治疗 ,观察其疗效。方法　正畸牙周联合治疗 16例患者唇向散开的上前牙 ,使用临床牙周健康指数分析、根尖片观察牙槽骨高度变化及模型分析的方法比较治疗前后的变化。结果　离断牙槽嵴顶纤维后正畸压入使牙槽骨高度平均增加 1 2mm ,前牙覆盖由 7 0mm减至 2 0mm ,覆由 4 0mm减至 2 0mm;牙周组织健康指数无明显变化。结论　经环切离断牙槽嵴顶纤维后 ,正畸压入治疗在矫正患牙咬合关系的同时可改善牙周组织状况 ,增加牙槽骨高度

Combined orthodontic-periodontal treatment on periodontal patients with anterior displaced incisors

Objective Combined orthodontic periodontal treatment with supracrestal fiberotomy was undergone on the periodontal patients with anterior displacement of incisors Evaluate of the changes before and after treatment Methods Periodontal indices, periapical x ray analysis, and model analysis were used for investigating the changes of alveolar bone height and periodontal health by orthodontic treatment following supracrestal fiberotomy of anterior displaced incisors on periodontal patients Results Alveolar bone height was increase by 1 2 mm in fiberotomy patients The overjet was reduced from 7 0 mm to 2 0 mm, while the overbite was decreased from 4 0 mm to 2 0 mm, and the periodontal health maintained as well Conclusion Combined orthodontic periodontal treatment with supracrestal fiberotomy could correct the malpositioned teeth, and improve the periodontium conditions and gain the crest bone
