牙周炎患者正畸介入时机的临床考量OA

Periodontitis often presents with reduced peri-odontal support tissues,pathological tooth migration,and oc-clusal disturbances.Orthodontic treatment can help to correct malocclusions such as disordered tooth alignment and in-creased diastema,alleviate traumatic occlusion,and potential-ly promote bone remodeling.However,reduced periodontal support tissues,persistent inflammation and increased plaque burden induced by orthodontic appliances can make orthodon-tic treatment in patients with periodontitis more challenging,and inappropriate orthodontic force may result in adverse out-comes such as alveolar bone resorption,gingival recession,and root resorption.Therefore,the timing of orthodontic inter-vention is a critical clinical decision that affects periodontal tissue safety.Based on the 2018 Classification System for Peri-odontal and Peri-implant Diseases and Conditions as a frame-work,this review integrates the S3 level clinical practice guideline of the European Federation of Periodontology(EFP),group standards,and relevant research evidence in re-cent years to explore the optimal timing of orthodontic inter-vention in periodontitis patients from multiple perspectives,in-cluding periodontal treatment endpoints,inflammation con-trol,risk stratification,and compliance assessment.It is hoped that this review can provide valuable references for clinical de-cision of periodontists and orthodontists.
