골격성 II급 법랑질형성부전증 환자에서 투명교정장치와 전악 보철 재치료를 통한 돌출입 개선

Abstract

This case report presents a 23-year-old female patient with skeletal Class II malocclusion, full-mouth fixed prosthesis due to amelogenesis imperfecta (AI), and lip protrusion. Treatment involved total arch distalization of both the maxilla and mandible using clear aligners combined with orthodontic miniscrews. Initially, the maxillary and mandibular molars were distalized, using the anterior dentition as an anchor. Miniscrews were then inserted and connected to the first molars to stabilize their position. Anterior dentition retraction was achieved by utilizing miniscrews as indirect anchors alongside the first molars. Further facial profile enhancement was achieved from the space gained through the reformation of the old anterior prosthesis. After the treatment, the patient exhibited an improved facial profile, esthetic smile line, and proper occlusion. These results was well-maintained after 12 months of retention.
