Amelogenesis Imperfecta with Anterior Open Bite: A Rare Case Report

Amelogensis Imperfecta

This clinical report describes the treatment plan for a young patient affected by amelogenesis imperfecta with anterior open bite.

The objectives of the treatment were to eliminate tooth sensitivity while enhancing esthetics and restoring masticatory function. Treatment included resin composite laminate veneers on maxillary anterior teeth and stainless steel crowns for posterior teeth.

INTRODUCTION : Amelogenesis imperfecta (AI) has been described as a group of hereditary conditions that disturbs the developing enamel structure and exists independent of any related systemic disorder.


This enamel anomaly affects both the primary and permanent dentition. The incidence of AI has been reported to vary between approximately 1:700 and 1:16,000, depending on the population studied and the diagnostic criteria used.

There are three types of AI: Hypoplasia, hypocalcifica-tion and hypomaturation. In the hypoplastic forms, the enamel does not develop to its normal thickness.

In the hypocalcified forms, the enamel thickness on the newly erupted teeth closely approaches that of normal teeth, but the enamel is soft, friable and can easily be removed from the dentin. Hypomaturation is an abnormal occurrence in the final stages of the mineralization process.

Hypomatu-ration differs from hypocalcification in that the enamel is harder, but with a mottled opaque white to yellow-brown or red-brown color. According to Seow, the primary clinical problems of AI are esthetics, dental sensitivity and decreased occlusal vertical dimensions.
