Amelogenesis Imperfecta, hypoplastic type associated with some dental abnormalities: a case report

Abstract

Amelogenesis imperfecta (AI) is a hereditary disorder expressing a group of conditions that cause developmental alterations in the structure of enamel. AI is a serious problem that reduces oral health-related quality of life and causes some physiological problems. The treatment of patients with AI may upgrade the quality of life and reinforce their self-esteem. Among the treatment options for AI, full-mouth metal reinforced porcelain restoration constitutes an important alternative because of its properties. This paper presents a case of AI of the hypoplastic rough type associated with a group of dental anomalies, and describes the prosthetic management of the patient. A 26-year-old female patient presented with a chief complaint of discolored teeth. Clinical and radiographic examination of the patient confirmed the diagnosis of rough pattern hypoplastic AI. The patient was treated with full-mouth metal reinforced porcelain fixed bridge. The adaptation of the temporomandibular joints and masticatory muscles was carefully observed periodically during 4 months and, after this period, the patient tolerated well her new vertical dimension. The patient received instructions on cleansing of the subpontic and interproximal areas. Follow-up visits were scheduled at 3 months and then at 6 months. No esthetic or functional problems were seen after the follow up period.

Functional and Esthetic Rehabilitation of a Young Patient with Amelogenesis Imperfecta

“…Depending on appearance of enamel and the hypothesized developmental defects, AI is classified into four patterns: Hypoplastic, hypomaturation, hypocalcified, and hypomaturation-hypoplastic. [1][2][3]7 The hypoplastic type is characterized by well-mineralized enamel, but its amount is reduced as seen in the radiograph 8 (Fig. 1B).…”

Aesthetic full-mouth oral rehabilitation of a young adult with amelogenesis imperfecta: a clinical report

“…11,41 Nevertheless, marginal adaptation and bonding problems have been pointed out as disadvantages of laminate veneers. 42,43 In some instances, high strength ceramic restorations do not require adhesive bonding to tooth structure and can be placed using conventional cements which rely only on micromechanical retention. 44 However, the laminate restorations has better esthetic appearence and more concervative approach, their marginal adaptation and bonding problems caused not to prefer as our treatment tecnique.…”

Correction of malocclusion and oral rehabilitation in a case of amelogenesis imperfecta by insertion of dental implants followed by Le Fort I distraction osteogenesis of the edentulous atrophic maxilla

“…Rowley et al reported that 20% of AI cases have severe anterior open bite, while 44% have vertical dysgnathia [8]. However, the association of AI and delayed eruption has been little studied [10, 11]. …”
