目的:通过使用微种植体支抗矫治慢性牙周炎患者深覆畸形,并进行临床疗效分析,探讨微种植体支抗用于牙周病深覆矫治的可行性。方法:选择12例伴有深覆的慢性牙周炎患者,根据后牙松动的情况,选择微种植体支抗的植入部位,分别有6例植入上颌前牙区,6例植入下颌前牙区。根据剩余牙槽骨的高度,施加压低力。测量矫治前后的根吸收情况及牙槽骨高度变化情况,并进行统计学分析。结果:前牙区植入微种植体支抗可以有效地打开前牙咬合;施加压低力的前牙与矫治前相比出现明显地根吸收;前牙区牙槽骨高度与矫治前相比无明显变化。结论:微种植体支抗用于慢性牙周炎深覆的矫治具有可行性,但只限于不能使用常规方法的病例。使用过程中一定要根据剩余牙槽骨量施加适当压低力。
OBJECTIVE: To investigate the feasibility of micro-implant anchorage for the treatment of periodontal disease with deep overburden by using micro-implant support to treat deep overburden deformity in patients with chronic periodontitis. Methods: Twelve patients with chronic periodontitis with deep overburden were selected. Sixteen cases were implanted into the anterior mandibular anterior region and 6 cases were implanted, respectively, according to the loosened posterior teeth. Anterior mandibular area. Depending on the height of the remaining alveolar bone, a depression force is applied. Measurement of root resorption before and after treatment and alveolar bone height changes, and statistical analysis. RESULTS: Micro-implant anchorage in the anterior teeth area could effectively open the anterior teeth occlusion. Compared with the pre-treatment, there was obvious root resorption in the anterior teeth. The alveolar bone height in anterior teeth area was no obvious change. CONCLUSIONS: The use of micro-implant anchorage in the treatment of chronic deep periodontitis is feasible, but only in cases where conventional methods can not be used. Use the process must be based on the remaining amount of alveolar bone to exert appropriate pressure.
