Introduction: Amelogenesis Imperfecta (AI) is a rare hereditary condition affecting enamel structure, often

resulting in negative effects on dental function and aesthetics. The clinical management of AI becomes

exponentially more complex when it presents as part of a systemic syndrome, such as distal renal tubular

acidosis (dRTA), a condition that impairs the kidney's ability to acidify urine, often linked to

nephrocalcinosis and hearing or visual impairments. This diagnosis necessitates a careful treatment plan.

Case Description: A 21-year-old female patient diagnosed with AI and dRTA presented with severe

plaque accumulation, low vertical dimension of occlusion (VDO), and extensive enamel hypoplasia. Key

clinical challenges included the patient’s significant visual impairment, which heightened their tactile

sensitivity and fear of the unknown, manifesting as dental anxiety. The systemic dRTA required

monitoring of metabolic stability. Intra-oral examination revealed yellowish-brown color, pitted enamel

surfaces, requiring a full-mouth rehabilitation to restore function and aesthetics.

Management: Following medical clearance a full-mouth rehabilitation was planned. To preserve the

maximum amount of fragile tooth structure while providing high fracture resistance, monolithic zirconia

crowns were selected. The VDO was increased using a long-term provisional restorations before the final

cementation of the monolithic zirconia crowns

Conclusions: The use of monolithic zirconia provided a biocompatible, durable, and aesthetically pleasing

result that successfully addressed the functional deficits. Patient exhibited a significant reduction in dental

anxiety.
