ABSTRACT

Orthodontic treatment in periodontally compromised adult patients has proven to have long-term stability when both specialties combine efforts with the use of light and continuous forces, good periodontal therapy and proper dental hygiene restoring aesthetic and functional problems thus preventing relapse after treatment. This case report describes a female patient, 58 years of age, with no medical conditions, canine and molar class I, controlled chronic generalized periodontitis, extruded upper incisors, diastemas, gingival recession and dental mobility, vertical and horizontal bone defects, bi-protrusive skeletal class I. Objective: Evaluate the response of periodontal tissue using orthodontic intrusion. 0.018” x 0.022” Roth appliances were used and after treatment, upper Hawley and lower bonded retainers. Results: 3 mm bone gain at the upper incisors area and 1 mm in insertion of the gingival tissue; a 3 mm intrusion was obtained thus shortening the length of the clinical crown. Conclusion: Multidisciplinary action is effective in intrusion movements that seek to increase alveolar bone as well as gingival insertion, reducing the depth of the periodontal pockets without root resorption and improving the patient’s esthetics.
