背景:在牙隐裂的综合治疗过程中,采用正畸带环和树脂临时冠进行暂时性保护,能够有效防止牙体折裂,保护患牙,临床成功率较高.目的:对比正畸带环和树脂临时冠对隐裂牙暂时性保护的临床效果差异.方法:纳入牙隐裂患者189例,其中男97例,女92例,年龄19-65岁,随机分2组,分别采用正畸带环(n=93)、树脂临时冠(n=96)在综合治疗过程中对牙隐裂进行暂时性保护,观察两组患牙固位、牙周状况和患者满意度方面的临床效果.结果与结论:正畸带环组出现3例带环松动和1例带环脱落;树脂临时冠组出现2例脱落,两组固位效果比较差异无显著性意义.正畸带环组11例出现牙龈炎或探诊出血,树脂临时冠组2例出现引起牙龈炎或探诊出血,树脂临时冠组牙周状况优于正畸带环组(P < 0.05).正畸带环组有18例因带环颜色不美观、佩戴橡皮圈引起的膨胀感、带环凸出牙体表面引起不适等原因,满意度较低;树脂临时冠组有 3 例患者不满意,树脂临时冠组患者满意度高于正畸带环组(P < 0.05).表明树脂临时冠在隐裂牙综合治疗过程中,其外形、色泽、舒适度等方面性能优异,具有良好的临床效果.

BACKGROUND:In the comprehensive treatment of cracked teeth, the temporary protection using the orthodontic band and resin temporary crown can effectively prevent tooth fracture and protect the cracked teeth with a higher clinical success rate. OBJECTIVE:To evaluate the differences in clinical efficacy of orthodontic band and resin temporary crown on the temporary protection of cracked teeth. METHODS: Totaly 189 patients (97 males and 92 females, aged 19-65 years) with cracked teeth were selected, randomly divided into two groups and respectively underwent the temporary protection to cracked teeth with the orthodontic band (n=93) and resin temporary crown (n=96) in the comprehensive treatment. Retention effect, periodontal status and patient satisfaction were observed. RESULTS AND CONCLUSION:There were three cases with loose band and one case with faling band in the group of orthodontic band; there were two cases with faling band in the group of resin temporary crown. No significant difference between two groups in the retention effect was found. There were 11 cases of gingivitis or exploring hemorrhage in the group of orthodontic band and 2 cases in the group of resin temporary crown, indicating the periodontal status in the group of resin temporary crown was better than that in the group of orthodontic band (P< 0.05). There were 18 cases of lower satisfaction for poor color, expand feeling caused by the rubber band and discomfort caused by the band protruding from tooth surface in the group of orthodontic band; there were 3 cases of lower satisfaction in the group of resin temporary crown, and the patient satisfaction in the group of resin temporary crown were higher than that in the group of orthodontic band (P < 0.05). There is a better clinical effect in the temporary protection to cracked teeth by using the resin temporary crown, especialy in the terms of retention effect, periodontal status and patient satisfaction.
