Implant-based oral rehabilitation of a variant model of type I dentinal dysplasia: A rare case report

Abstract

Dentin dysplasia is an exceptionally rare, autosomal-dominant, hereditary condition, primarily
characterized by defective dentin formation affecting both the deciduous and permanent
dentitions. The etiology remains imprecise to date, in spite of the numerous hypotheses put
forward and the constant updates on this condition. This case report of type I dentin dysplasia
exhibits radiographic fi ndings that are unique and diverse from the classical fi ndings of various
subtypes of this disease reported to date. This article also depicts the implant-based oral
rehabilitation of the young patient diagnosed with this variant model of dentin dysplasia type I.
Early diagnosis and implementation of this preventive and curative therapy is vital for avoiding
premature exfoliation of deciduous and permanent dentition and the associated residual ridge
resorption, thereby overcoming functional and esthetic defi cits and ensuring protection of the
remaining dentition from further harm.
