Cureus. 2024 Oct 6;16(10):e70942. doi: 10.7759/cureus.70942. eCollection 2024 Oct.

Abstract

Amongst the spectrum of dental developmental anomalies, hypodontia is a condition characterized by congenitally missing teeth. Whereas, hyperdontia is a condition that results in the development of an excessive number of teeth. These two conditions are regarded as polar opposites in the progression of dentition development. Their simultaneous occurrence in a patient results in a rare phenomenon known as concomitant hypo-hyperdontia (CHH). This report presents a case of CHH highlighting the importance of diagnosis and adequate treatment planning in achieving a balanced and esthetic smile.
