正畸治疗中、重度慢性牙周炎及美学重建切牙区的临床研究

目的:分析正畸治疗中、重度慢性牙周炎及美学重建切牙区的临床效果。方法:选择我院自2017年1月~2019年6月接诊的106例中、重度慢性牙周炎患者作为研究对象,随机分为对照组和观察组,每组各53例。对照组予以牙周综合性治疗,观察组在对照组治疗的基础上,联合正畸治疗。在治疗前1 d及治疗6个月后,分别测量两组患者探诊深度(probing depth,PD)、牙龈指数(gingival index,GI)、菌斑指数(plaque index,PLI)、龈沟出血指数(sulcus bleeding index,SBI)、临床牙周平均附着丧失(clinical periodontal mean attachment loss,CAL)、龈乳头指数(licking papillary index,PI)、龈乳头高度(licking nipple height,PH)、邻接点至牙槽骨嵴之间的距离(adjacent point to alveolar the distance between the epiphyses,BC-CP),并比较两组治疗前后的牙齿松动度。结果:两组患者均顺利完成治疗;治疗6个月后,观察组治疗后PD、GI、PLI、SBI、CAL均明显小于对照组,治疗后PI分布情况明显优于对照组,治疗后PH、BC-CP均明显大于对照组(P<0.05);观察组治疗后牙齿松动度明显小于对照组(P<0.05)。结论:正畸治疗对中、重度慢性牙周炎具有良好的治疗效果,有助于纠正牙体畸形、控制菌斑、改善咬合关系和牙龈状态,促进切牙区美学重建。

Clinical study of orthodontic treatment for moderate and severe chronic periodontitis and aesthetic reconstruction of the incisor

Objective:To analyze the clinical effects of orthodontic treatment for moderate and severe chronic periodontitis and aesthetic reconstruction of the incisor area.Methods:Totally 106 patients with moderate to severe chronic periodontitis were selected as subjects that divided into control group and observation group,with 53 cases in each group.The control group received comprehensive periodontal treatment,the observation group was combined with orthodontic treatment on the basis of the control group.Before and after 6 months of treatment,the probing depth(PD),gingival index(GI),plaque index(PLI),sulcus bleeding index(SBI),clinical periodontal mean attachment loss(CAL),licking papillary index(PI),licking nipple height(PH)and adjacent point to alveolar the distance between the epiphyses(BC-CP) were observed,and the looseness of the teeth before and after treatment was compared.Results:Both two groups were successfully treated and were followed up for 6 months.The PD,GI,PLI,SBI and CAL in the observation group were significantly lower than those in the control group,the distribution of PI was significantly better than that in the control group,the PH and BC-CP levels were significantly higher than those in the control group respectively(P<0.05).The degree of tooth loosening in the observation group was significantly lower than that in the control group(P<0.05).Conclusion:Orthodontic treatment has a good therapeutic effect on moderate,and severe chronic periodontitis,it can help to correct dental malformation,control plaque,improve occlusion and gum status,and promote aesthetic reconstruction of incisor area,worthy of further research and application.
