3D导板引导下微创骨皮质切开术辅助正畸治疗骨性Ⅱ类错畸形的临床研究
3D guide-guided minimally invasive osteocorticotomy assisted orthodontic treatment of skeletal Class Ⅱ malocclusions:A clinical study
摘要
Abstract
Objective:To explore the clinical effect of Piezocision guided by three dimensions(3D)printing guide plate to assist skeletal Class Ⅱ malocclusion correction.Methods:Twenty-four patients with skeletal Class Ⅱ malocclusion were selected from our hospital.The treatment plan involved the extraction of the bilateral maxillary first premolars and anterior retraction by mini-implant anchorage in upper arch.The patients were randomly divided into two groups:The control group underwent conventional orthodontic treatment,while the research group underwent Piezocision guided by 3D printing guides at the beginning of the space-closing phase of the orthodontic treatment.The loading method was the same as that of the control group after the operation.The indexes related to the changes of hard and soft tissues and the treatment effects of the two groups were recorded for analysis and comparison.Results:In the research group,the change value of U1-SN was(-1.49±2.18)°,U1-NA was(-5.63±3.39)°,NA-Apo was-4.10(-4.60,-2.00)°,U1-Apo was(-3.10±0.95)mm.There was significant difference comparing with the control group.The average speed of movement of the teeth in the research group during the process of space closure was(0.90±0.21)mm per month,which was significantly faster than that of the control group[(0.54±0.15)mm per month].None of the roots were damaged after operation,and there was no significant difference in the degree of root resorption and the depth of periodontal probing between the research group and the control group after the treatment.Conclusion:In skeletal Class Ⅱ malocclusion correction,3D printing-guided Piezocision can effectively realize the overall movement of the maxillary anterior teeth,shorten the treatment time,and have fewer surgical complications,which can be viewed as an effective adjuvant treatment of patients with skeletal Class Ⅱ malocclusion undergoing orthodontic treatment.关键词
