Management of bilaterally missing mandibular central incisors
A case report
Keywords:
mandibular incisors, microdontia, dentoalveolarAbstract
The present case report describes the interdisciplinary management of a patient with increased overbite and overjet, Angle’s Class Ⅰ malocclusion, bilateral agenesis of the mandibular central incisors and microdontia of the upper lateral incisors. The 18-year-old female patient had a convex profile, maxillary dentoalveolar protrusion and mild spacing in the mandibular anterior region. Therefore, treatment consisted of fixed appliance therapy, followed by replacement of the one lower incisor with an endosseous implant supported prosthesis and aesthetic build-up of the upper lateral incisors. The method of treatment has significantly improved the patient’s facial and dental aesthetics and provided a good functional occlusion, despite the absence of a mandibular incisor.
