병적 치아 이동이 있는 만성 치주염 환자에서 투명 교정 장치 치료가 치주 상태에 미치는 영향

Abstract

If orthodontic force was added on periodontal tissue with inflammation, faster destruction on tissue would appear. Currently, however, it is reported that orthodontic treatment after periodontal treatment is not contra-indication but it even increases possibility of maintaining teeth and it dose not increase activity of disease during orthodontic treatment. The majority of cooperative treatment in periodontics-orthodontics requires fixed orthodontic apparatus in maxillary/mandibular jaw but a part can plan to move teeth with simple removable orthodontic apparatus. The purpose of this study is to evaluate the effect of treatment of pathologic tooth migration with chronic periodontitis using clear aligner on periodontal status. In this study, cause-related periodontal therapy was performed in patients with chronic periodontal disease and movement of teeth using clear aligner was planned. And periodontal clincial parameters(gingival recession, probing pocket depth, clincal attachment level) was checked before and after treatment for checking the periodontal status. Clear aligner is relatively easy to manufacture and cost-effective. Since its manufacture is performed on plaster model, accurate teeth movement is possible with this. It is also effective and efficient in moving teeth because of the structure of wrapping entire teeth. After orthodontic movement with clear aligner, clinical periodontal parameters were maintained and periodontal health is not influenced by the tooth movement. Therefore, we suggested that clear aligner is effective apparatus for relatively simple teeth movement of pathologic tooth migration with chronic periodontitis, and it could plan to move teeth within relatively short period without loss of attchment appratus.
