Abstract

Key Clinical MessageAmelogenesis imperfecta (AI) is typically associated with anterior open bite and a number of other dental problems, which require complex treatments such as orthognathic surgery. This case report describes management of a patient with AI and severe open bite via a multidisciplinary approach.

Highlights

Amelogenesis imperfecta (AI) is a rare inherited disorder characterized by incomplete formation or calcification of the enamel, affecting both the primary and permanent dentition.[1,2,3]
Tooth hypersensitivity, wide pulp chamber, higher risk of dental caries, and decreased occlusal vertical dimension are among the challenges faced in the management of AI
Dental anomalies associated with AI include enamel disorders, anterior open bite, pulpal calcifications, delayed eruption of teeth, pathological root and crown resorption, and taurodontism.[7,8]

Summary

| INTRODUCTION

Amelogenesis imperfecta (AI) is a rare inherited disorder characterized by incomplete formation or calcification of the enamel, affecting both the primary and permanent dentition.[1,2,3] The global prevalence of AI is estimated between 1:1700 and 1:14 000, based on the study populations and the diagnostic criteria.[4,5,6]. Lateral cephalometric studies and consultation with oral and maxillofacial surgeons led to the conclusion that the patient had maxillary deficiency, mandibular prognathism, and anterior open bite. The first phase of the surgical procedure involved slight superior repositioning and setback of the anterior mandible, as a result of which, the curve of Spee, open bite, and class III jaw relationship improved.[13] The second phase included a bilateral posterior maxillary segmental osteotomy for superior repositioning to correct the open bite, long face, and space shortage of the posterior teeth. Esthetic analysis was carried out and the patient's smile line was transferred to the cast Based on this cast, a surgical stent was fabricated for crown lengthening surgery and leveling of the gingiva (Figure 6A,B). A customized anterior guidance table and the posterior determinant of occlusion were designed based on the casts of the temporary crowns in Denar Mark II articulator, and the final crowns were fabricated (Figure 10).
