玻璃离子水门汀与牙釉质粘结剂在口腔正畸中的应用效果比较

Comparison of clinical effects of glass ionomer cement and enamel binder on malocclusion deformity

目的 比较采用玻璃离子水门汀与牙釉质粘结剂治疗错颌畸形的临床效果。方法 68例口腔正畸患者按采用的材料不同分为观察组和对照组,每组各34例,观察组采用玻璃离子水门汀进行粘合,对照组采用牙釉质粘结剂进行粘合,两组患者均采用多曲方丝弓矫治器进行矫正治疗。比较两组临床治疗效果。结果 经过治疗随访,观察组托槽脱落、脱矿、龋齿等发生率均明显低于对照组（χ2=3.486、2.938、3.486,均P＜0.05）,观察组治疗后患者满意度明显高于对照组（χ2=2.047,P＜0.05）;两组治疗过程中并发症和不良反应发生率差异均无统计学意义（均P＞0.05）。结论 玻璃离子水门汀在口腔正畸术治疗的临床粘结效果好,最大限度减少托槽脱落、脱矿,并且操作简便、安全可靠,值得在临床广泛应用。

Objective To compare the clinical effects of glass ionomer cement and enamel binder therapy on malocclusion deformity.Methods 68 orthodontic patients were divided into observation group and the control group,34 cases in each group.The observation group was given glass ionomer cement bonding,the control group was given enamel adhesive bonding.All patients in the two groups received multiloop edgewise arch appliance orthodontic treatment.The clinical outcomes were compared between two groups.Results After treatment follow-up,the incidence rate of brackets off,demineralization and caries in observation group was significantly lower than the control group（χ2=3.486,2.938,3.486,all P〈0.05）.The satisfaction of patients in the observation group after treatment was significantly higher than control group（χ2=2.047,P〈0.05）.The incidence rate of complications and adverse reactions during treatment showed no significant difference between the two groups （P〉0.05）.Conclusion Glass ionomer cement has good bonding effect in orthodontic treatment,and can minimize the brackets off,demineralization,and easy to operate,safe and reliable,which worthy of clinical applications.
