口腔正畸治疗中微型种植体支抗的稳定和安全性
Stability and safety of mini-implant anchorage in orthodontic treatment
摘要
Abstract
BACKGROUND: Traditional orthodontic anchorage has the disadvantages of discomfort, difficult to control, affecting the appearance, and relying on patient’s close cooperation. Because of short-time clinical research and application, mini-implant anchorage has a great controversy in the orthodontic treatment. OBJECTIVE: To explore the application value of mini-implant anchorage in the orthodontic treatment. METHODS:Eighty cases undergoing the orthodontic treatment at the Center of Ophthalmology and Otolaryngology, Yaan People’s Hospital in China from January 2012 to June 2015 were enrol ed in this study. These patients were equal y randomized into test group and control group, which were subjected to mini-implant anchorage or headgear anchorage, respectively. The treatment was continued for 2 years in the two groups. RESULTS AND CONCLUSION: After the treatment, the successful rate in the test group was significantly higher than that in the control group (P < 0.05); the upper central incisor convex distance difference, inclination angle of the upper central incisor, displacement of the molar, SNA angle, inter-canine width, were significantly better in the test group than the control group (P < 0.05). At weeks 4 and 8 after intervention, there was no difference in the expression of osteoprotegerin in the periodontal tissue between the two groups (P > 0.05), but the rate of adverse reactions was significantly lower in the test group than the control group (P < 0.05). These findings indicate the mini-implant anchorage method can significantly improve the therapeutic efficacy, improve the success rate of treatment, and reduce the incidence of postoperative infections, which has good safety and stability, and has good clinical application value.关键词
