(英) Interdisciplinary therapy for severe periodontitis with Angle Class II Division 1 malocclusion: A case report with 7-year follow-up

(英) Previous studies have suggested that occlusal discrepancy is a risk factor contributing to periodontal disease. Occlusal discrepancy could increase the risk of developing infrabony defects. The authors present a case of a patient with severe periodontitis who exhibited many infrabony defects in the molar region due to malocclusion-induced trauma. They report the 7-year treatment outcomes of the patient after periodontal regenerative and comprehensive orthodontic therapies for functional recovery with implant prosthodontics. A 56-year-old woman sought treatment with the chief symptom of masticatory disturbance. In the molar region, excessive tooth mobility, deep periodontal pockets, and infrabony defects were observed. She had excessive overjet, resulting in collapse of anterior guidance. Malocclusion was considered to be an exacerbating factor of the infrabony defects. After initial periodontal therapy, the authors performed periodontal regenerative therapy in the mandibular molar regions. The authors carefully placed implants in a position in the maxillary molar region that would ensure an appropriate anterior dental relationship after orthodontic treatment. Comprehensive orthodontic treatment was subsequently performed, using implants as anchoring units. Definitive surgery was then performed on the mandibular molars before placing the final prosthesis. Favorable periodontal condition and stable occlusion have been maintained for the 7-year posttreatment period. Comprehensive and interdisciplinary treatment enables stable occlusion and establishment of periodontal and peri-implant tissues with high cleansability, even in patients with severe periodontitis and malocclusion. In this case, a favorable long-term treatment outcome can be expected.
