Alteração de DVO em paciente com amelogênese imperfeita do tipo hipomaturada: relato de caso

Abstract

Alteration of vertical dimension of occlusion (VDO) in a patient with hypomaturation of amelogenesis imperfecta: a case report. Amelogenesis imperfecta (AI) is a hereditary condition that affects enamel formation. The hypomatured type is characterized by weak enamel prone to early wear, which may lead to a reduction in vertical dimension of occlusion (VDO). This study aims to report a clinical case of a patient with hypomatured AI, addressing the change in VDO to a larger one and the provisional restorative protocol adopted. The treatment plan included articulator mounting, diagnostic wax-up, and provisional composite resin restorations for VDO testing. A phonetic test with sibilant sounds was performed to determine whether functional free space was compromised. Additionally, a longitudinal assessment of muscle and joint function was conducted, considering signs of pain and muscle fatigue. This step aimed to verify whether the new vertical dimension of occlusion (VDO) allows natural speech production without compromising phonation, articulation, or functional comfort. The results showed functional and aesthetic improvement with good patient adaptation to the new VDO. This study emphasizes the importance of early diagnosis and a multidisciplinary approach in the rehabilitation of patients with AI and VDO loss.
