目的 探讨Tip-Edge Plus差动直丝弓技术治疗伴有重度深覆(牙合)和深覆盖错(牙合)畸形不同治疗阶段软硬组织的变化.方法 样本包括恒牙初期伴有重度深覆(牙合)和深覆盖的前突错(牙合)畸形患者23例,平均年龄13.6±1.8岁.上颌均拔除第一双尖牙,下颌拔除第二双尖牙14例,拔除下颌第一双尖牙9例,并使用Tip-Edge Plus技术治疗,治疗前、第一期打开咬合后、第二期关闭拔牙间隙后和第三期正轴完成后分别拍摄头颅侧位片并测量,进行随机区组设计资料的方差分析和多个均数之间两两比较的q检验.结果 治疗后患者覆(恰)、覆盖和软硬组织侧貌明显改善.打开咬合发生在第一期,覆(牙合)从5.35 mm减小到0.52 mm(P＜0.05).上颌切牙的倾斜度U1/SN第一、二期分别减小20.21°和7.56°(P＜0.05),第三期增加10.16°(P＜0.05)；上中切牙突度U1-AP第一、二期分别减小6.41 mm和2.79 mm(P＜0.05),第三期增加2.19 mm(P＜0.05).结论 未使用额外支抗的Tip-Edge Plus技术能够成功矫正伴有重度深覆(牙合)和深覆盖错(牙合)畸形,打开咬合发生在治疗第一期,第三期能够控制上切牙的根舌向转矩移动.

Objective To investigate the skeletal and soft tissue changes at the three different stages on the malocclusion with severe overbite and overjet treated by Tip-Edge Plus technique.Methods The sample comprised 23 malocclusion with severe overbite and overjet patients in adolescence (age 13.6± 1.8 years).First premolars were extracted in maxilla in all patients.Lower second premolars of 14 patients and lower first premolars of 9 patients were extracted.All patients were treated by Tip-Edge Plus technique,4 lateral cephalometric radiographs were taken before treatment,after stage Ⅰ of opening overbite,after stage Ⅱ of closing space and after treatment.Computerized cephalometric analysis was carried out.ANOVA and q test were performed using software package SAS 8.0.Results After treatment,highly significant changes were noted in overbite,overjet and soft profile.Overbite decreased from 5.35 mm to 0.52 mm at stage Ⅰ (P＜0.05).U1/SN decreased 20.21° at stage Ⅰ,decreased 7.56° at stage Ⅱ and increased 10.16° at stage Ⅲ (P＜0.05).U1-AP decreased 6.41 mm at stage Ⅰ,decreased 2.79 mm at stage Ⅱ and increased 2.19 mm at stage Ⅲ (P＜0.05).Conclusions Malocclusion with severe deep overbite and overjet could be treated successfully by Tip-Edge Plus technique in adolescence.Overbite opening happened at stage Ⅰ.Both torque and tip of teeth could be corrected at stage Ⅲ.
