【摘要】：目的研究腭侧微螺钉型种植体支抗在上颌前突治疗中的临床应用效果。方法选择上颌前突需强支抗矫治的患者22例,年龄18~25岁,分试验组和对照组,每组11例,试验组于上颌双侧腭侧应用微螺钉型种植体支抗,对照组用口外弓支抗,治疗前后采用X线对头颅片进行测量,比较2组治疗前后软硬组织的变化差异。结果试验组:治疗后U1-NA(mm:3.08±1.18 vs 8.15±3.05)、U1-SN(101.90°±3.50°vs 117.90°±6.05°)较治疗前减小,U1-L1(123.98°±5.78°vs 103.89°±8.95°)较治疗前增大(P0.05)。对照组:治疗后U1-NA(mm:5.01±1.34 vs 9.12±2.13)、U1 SN(101.90°±3.97°vs 114.87°±7.69°)较治疗前减小,U1-L1(126.01°±3.12°vs 112.98°±5.98°)、U6-PtPNS(mm:21.45±2.43 vs 18.36±2.19)较治疗前增大(P0.05)。试验组U1-L1(19.48°±8.90°vs 13.01°±5.90°)数值改变量大于对照组,U6-PtPNS(mm:0.90±0.29 vs 3.78±0.12)数值改变量小于对照组(P0.05)。结论治疗上颌前突患者,上颌需要强支抗时,可应用腭侧微螺钉型种植体支抗。
[Abstract]:Objective to study the clinical application of palatal microscrew implant Anchorage in the treatment of maxillary protrusion. Methods 22 patients with maxillary protrusion, aged 1825 years, were divided into experimental group and control group with 11 cases in each group. The experimental group was treated with microscrew implant Anchorage on both sides of maxillary palate and the control group with external arch Anchorage. The head films were measured by X-ray before and after treatment. Results: after treatment, U1-NAmmV: 3.08 卤1.18 vs 8.15 卤3.05 掳U1-SN101.90 掳卤3.50 掳vs 117.90 掳卤6.05 掳) decreased U1-L 1126.01 掳卤3.12 掳vs 123.98 掳卤5.78 掳vs 103.89 掳卤8.95 掳, compared with that before treatment. Control group: after treatment, U1-NAmmV: 5.01 卤1.34 vs 9.12 卤2.13U1 SN(101.90 掳卤3.97 掳vs 114.87 掳卤7.69 掳). The changes of U1-L1n 19.48 掳卤8.90 掳vs 13.01 掳卤5.90 掳) were higher in the experimental group than in the control group (0.90 卤0.29 vs 3.78 卤0.12). When strong Anchorage is needed in the maxilla, the palatine microscrew implant Anchorage can be used.
