Prosthetic Rehabilitation of Hypoplastic Type of Amelogenesis Imperfecta Using Semi Permanent Crowns – A Case Report

Abstract

Amelogenesis imperfecta (AI) is a group of tooth developmental disorder which has genetic causes

otherwise referred to as hereditary dysplasia, in the absence of systemic disorders. It affects both deciduous

and permanent dentition. The common problems associated with amelogenesis imperfecta (AI) is the risk of

wear of the tooth enamel and dental caries susceptibility. This clinical report describes esthetic and functional

prosthetic rehabilitation of hypoplastic type of Amelogenesis Imperfecta in a 13-year-old female patient

with generalised sensitivity in all her teeth, yellow-brown discolouration and wearing of the posterior teeth.

On clinical and radiographic examination, it was identified as hypoplastic type of Amelogenesis imperfecta

according to Witkop’s classification of AI. Prosthetic rehabilitation using semi permanent restoration for

permanent posterior teeth was performed quadrant wise in four appointments with minimally invasive crown

preparations and followed up at three months.
