Case report: A 49-year-old female patient diagnosed with generalized moderate chronic periodontitis, secondary occlusal trauma and pathological migration, treated with non-surgical and surgical periodontal therapy and orthodontic treatment, obtaining a gain of clinical attachment level and remission of the periodontal pockets.

Conclusion: The interdisciplinary relationship between periodontics and orthodontics is necessary in cases where the periodontally compromised patient presents malocclusion and occlusal trauma, where the treatment of one discipline facilitates the work of the other, benefiting the patient's oral conditions. It is important that orthodontic planning be carried out prior to periodontal therapy to get a long-term successful treatment.
