エナメル質形成不全を伴う全顎的再建：症例報告

BACKGROUND Amelogenesis imperfecta is a rare condition with a genetic predisposition that impacts enamel production, mineralization, or maturation. This condition impacts the affected individual's dental aesthetics, functionality, and emotional health. A multidisciplinary approach is recommended for effective management and a positive prognosis for dental treatment. CASE REPORT This case involves a 27-year-old woman diagnosed with amelogenesis imperfecta, characterized by extensive enamel defects, carious lesions, partial tooth loss, and significant aesthetic issues. The patient expressed dissatisfaction with the yellowish hue, uneven morphology, and small dimensions of her teeth. A comprehensive assessment revealed extensive enamel pitting, exposed dentin on several teeth, faulty dental restorations, multiple interdental gaps, misaligned teeth, and a class II malocclusion with a disparity between centric relation and maximum intercuspation. A staged, multidisciplinary treatment strategy was implemented, beginning with preliminary periodontal therapy and risk management, followed by surgical crown lengthening and the extraction of impacted or retained teeth. The final phase consisted of restorative rehabilitation, including posterior porcelain-fused-to-metal crowns, anterior lithium disilicate crowns, and fixed partial dentures. This treatment protocol successfully addressed the patient's aesthetic, phonetic, and functional needs. CONCLUSIONS This case highlights the complex management of amelogenesis imperfecta and underscores the critical need for individualized, interdisciplinary therapeutic approaches. A comprehensive literature review supports preventive interventions in childhood, adhesive and interim restorations in adolescence, and full-coverage prostheses in adulthood as the main components of effective management. When combined with patient motivation and a systematic recall schedule, favorable long-term prognoses can be achieved.
