Cases of screw-retained implant prosthesis in the anterior maxilla through multidisciplinary approach, including orthodontic teeth alignment

Abstract

The labio-palatal location of the implant in the maxillary anterior region is one of the important factors affecting the aesthetics of the implant prosthesis. However, the thin labial bone of maxilla could be absorbed in significant amounts after extraction of the teeth, which makes the implant be placed on the palatal side rather than the ideal location. In fact, in the cases of maxillary central incisor loss, UCLA was used for prosthetic restoration of palatally placed implant. In addition, with multidisciplinary treatment, GBR (Guided Bone Regeneration) was performed for compensating the absorbed alveolar bone and adjacent anterior tooth were aligned. Definitive restoration was performed after confirming aesthetic recovery of the gingiva with sufficient provisional restoration period. There were satisfactory results of functional and esthetic recovery of tooth loss through implant prosthesis.
