Pages 13-19, Language: EnglishRabie / Deng / JinElongated and spaced incisors are common in patients suffering from severe periodontal disease. Intrusion and uprighting of incisors might be the logical solution for this problem. This article describes a team appraoch to treatment planning for adult patients with severe localized periodontitis accompained by marginal bone loss and spacing and elongation of incisors. The treatment involves the combination of peridontal treatment, orthodontic intrusion, and prosthetic therapy. Controlled intrusion in two patients led to a decrease in the clinical crown length, better access for oral hygiene procedures, better gingival form, and a more suitable distribution of occlusal forces.
