中重度牙周炎患者因牙周组织丧失,在力的影响下牙齿伸长或移位,最终出现错畸形,进而加重牙周病患者的病情,对于该类患者牙周治疗中的第三阶段正畸治疗尤为重要.对于伴有错畸形的中重度牙周炎患者,因牙周组织丧失,在正畸治疗过程中存在较高风险,而牙周辅助加速成骨正畸治疗作为加快正畸治疗以及牙槽骨改建的一种临床技术,对于上述患者具有一定的临床指导意义,如何将上述技术与牙周治疗、正畸治疗合理应用需要更多的相关临床及实验研究来证实.“,”The patients with severe periodontitis due to periodontal tissue loss,under the influence of the occlusal force,have tooth elongation or displacement,which eventually develops into malocclusion,and thus aggravates the periodon-tal disease,therefore the third stage orthodontic treatment is particularly important for the patients.In the treatment of patients with severe periodontal disease with malocclusion, due to loss of periodontal tissue,there is a higher risk in the orthodontic treatment,and periodontal osteogenic accelerated orthodontics and remodeling the alveolar bone, have certain clinical significance for these patients.How to apply the above mentioned technology in periodontal treatment and orthodon -tic treatment need further related clinical and experimental studies to validate in the future.
