Coroa de aço inoxidável x coroa de zircônia na reabilitação de dentes com hipomineralização molar incisivo: relato de caso

Abstract

Incisor molar hypomineralization lesions can compromise the esthetics and function of permanent incisors and molars. Due to their structural characteristics, they are prone to biofilm accumulation and the development of associated carious lesions. Some patients have associated hypersensitivity. The objective of the present study was to carry out the rehabilitation of the lower first permanent molars of a patient who had MIH and associated carieslesions. In addition to describing restorative techniques with stainless steel and zirconia crowns. It was concluded that both options are viable alternatives to rehabilitate the function of permanent first molars compromised by MIH associated with carious lesions. CAIs are adapted by mechanical retention and require supragingival preparations. Due to their structural characteristics, they are prone to biofilm accumulation. In CZ, the retention is adhesive, and the preparation is subgingival. Because they have an extremely smooth and polished surface, they do not form biofilm. There is still not enough time for longitudinal follow-up and evaluation of clinical and radiographic performance. [resumo fornecido pelo autor]
