Full-Mouth Rehabilitation in a Young Adult With Severe Amelogenesis Imperfecta: a Case Report
Objectives: Amelogenesis imperfecta (AI) refers to a group of genetic disorders that affects enamel development.. AI has a serious impact on the self-esteem of the patient. The aim of this AI case report is to present a full-mouth rehabilitation with bonded lithium disilicate glass ceramic restorations.
Methods: A 23-years old male patient, with severe hypoplastic AI asked for an esthetic and functional rehabilitation. Well mineralized hypoplastic enamel was present in a very thin layer and the teeth were brown discolored. Old discolored composite veneers were present on the incisors and the patient had a compromised periodontal health. Orthodontic treatment was needed to correct the occlusal plane, the anterior open bite, the midline shift and the presence of diastemata and rotated premolars. The patient, however, refused to be treated orthodontically because of the high financial cost. Treatment started with a profound periodontal cleaning and oral hygiene instructions. Periodontal surgery was carried out to reduce the pocket depths. At the same time the height of the short clinical crowns in the posterior region was increased. A digital wax-up, made by the dental technician,
included an increase in the vertical dimension of occlusion. After evaluation of the mock-up, minimal invasive crown preps were made on 24 teeth. The digital wax-up was transferred intra-orally making use of temporary CAD-CAM crowns. Five months later, the teeth were restored with durable bonded lithium disilicate glass ceramic crowns.
Results: After total rehabilitation with monolithic lithium disilicate glass ceramic crowns, the masticatory function was restored. The problem of increased tooth sensitivity was solved and the restorations allowed to perform a good oral hygiene. The patient was very happy with the final esthetic result. This seriously increased his self-esteem.
Conclusions: Total rehabilitation of a patient with severe hypoplastic AI is complex and requires a structured treatment plan, in which different disciplines are involved. Regular periodontal and restorative follow-up is absolutely required to guarantee the durability and functionality of the total rehabilitation.
