| 目的探讨结合 Orapix软件的数字化间接粘接技术治疗安氏 Ⅱ类错 ??畸形的临床效果。方法选择 2018年 3—6月合肥市口腔医院安氏 Ⅱ类错 ??畸形病人 32例，采用随机数字表法将病人分为观察组和对照组，每组 16例，对照组采用在唇侧直接粘接自锁托槽技术，观察组采用数字化间接粘接自锁托槽技术，两组治疗期间每次复诊时记录托槽脱落情况，矫治结束后取石膏模型，拍摄全景片和头侧片进行美国正畸专家认证委员会客观评级系统( ABO-OGS)评分，比较两组粘接后托槽脱落率和矫治疗程，以评价两组治疗效果。结果观察组托槽脱落率 8.64%(33/383)高于对照组 5.00%(19/380)(P<0.05)；观察组矫治疗程( 18.13±2.39)月低于对照组( 20.75±2.49)月( P<0.05)；矫治结束后观察组 OGS总评分( 12.6±1.71)分少于对照组( 15.75±1.95)分(P<0.05)。其中边缘嵴高度评分观察组( 1.75±1.29)分少于对照组( 2.63±0.98)分、颊舌向倾斜度评分观察组 2.00(2.00，3.00)分少于对照组 3.00(2.00，3.00)分、牙根平行度评分观察组 2.50(1.00，3.00)分少于对照组 3.00(3.00，3.75)分( P<0.05)。结论数字化间接粘接技术在正畸矫治中较直接粘接技术精准，治疗疗程缩短，可在临床推广，但是操作要求高，需要减少其脱落率。 |

| Objective To investigate the clinical effect of digital indirect bonding technology combined with Orapix software in thetreatment of angle class Ⅱ malocclusion.Methods From March 2018 to June 2018, thirty two patients of angle class Ⅱ malocclusiondeformity in Hefei Stomatological Hospital were randomly divided into observation group and control group , 16 cases in each group.The control group was treated with direct bonding self-locking brackets on the labial side,while the observation group was treated with digital indirect self-locking brackets.The bracket falling off was recorded at each subsequent visit in the two groups.After the treatment,plaster model,panoramic film and cephalometric film were taken to assess outcome of the two groups by using American Board of Ortho?dontics Objective Grading system (ABO-OGS).Results The bracket exfoliation rate of the observation group was 8.64%(33/383) high? er than that of the control group was 5.00%(19/380) (P<0.05);the treatment course of the observation group (18.13±2.39) months waslower than that of the control group (20.75±2.49) months (P < 0.05);the OGS total score of the observation group (12.6±1.71) was lower than that of the control group(15.75±1.95) (P<0.05),and the height of marginal ridge of the observation group (1.75±1.29) was less thanthat of the control group (2.63±0.98), buccal and lingual inclination of posterior teeth of the observation group 2.00(2.00,3.00) was lessthan that of the control group 3.00(2.00,3.00), and root parallelism score of in the observation group 2.50(1.00,3.00) were lower thanthose in the control group 3.00(3.00,3.75) (P<0.05) .Conclusion Digital indirect bonding technology is more accurate than directbonding technology in orthodontic treatment,and the treatment course is shortened.It can be popularized in clinical practice,but the op?eration requirements are high, so it is necessary to reduce the falling off rate. |
