Resolução Estética de Dentes com Amelogênese Imperfeita: Relato de Caso

Abstract

Amelogenesis imperfecta is a genetic condition that affects the formation of tooth enamel, resulting in thin, fragile enamel with irregular coloration. Common clinical signs include aesthetic deficiencies, dental sensitivity, and loss of vertical dimension. Treatment involves restoring the enamel through direct or indirect restorations, depending on the complexity of each case. When the enamel is completely compromised, the total removal and coverage of the dentin with ceramic crowns become necessary. Feldspathic ceramics are widely used, offering excellent aesthetics, good resistance to compression and fatigue, although with lower resistance to flexion and fracture. This study reports the case of a young patient with severe amelogenesis imperfecta treated with crowns and veneers made of feldspathic ceramics. After 19 years, some of these restorations showed cracks, leading the patient to replace them with lithium disilicate veneers, a material recognized for its superior mechanical strength and excellent aesthetics. The replacement maintained the previously achieved functionality and aesthetics while increasing the durability of the restorations. It is concluded that feldspathic ceramics were effective in the initial rehabilitation, and the subsequent replacement with lithium disilicate proved to be an even more resistant and aesthetic alternative, ensuring the longevity of the treatment and the patient's satisfaction
