Prosthetic rehabilitation of malpositioned anterior dental implants can be challenging. Interdisciplinary treatment planning and precise execution of biologically acceptable prosthetic and surgical protocols are essential to achieve optimal esthetic results and while avoiding and managing esthetic complications. This case study focuses on the restorative aspect. Two sets of custom gold abutments were used prior to and following surgical correction of a pre-existing soft and hard tissue ridge defect surrounding maxillary central incisor implant restorations. A stable and esthetically pleasing result was documented 7 years following delivery of definitive esthetic central incisor implant restorations.

This case report presents the clinical application and outcomes of the use of a combined approach to treat a patient with a severe alveolar defect. Recombinant human bone morphogenetic protein-2 in an absorbable collagen sponge carrier, along with autogenous bone graft, bovine bone mineral, platelet-rich plasma, and guided bone regeneration, were used simultaneous with nonsubmerged implant placement. At 1 year postsurgery, healthy peri-implant soft tissues and radiographically stable peri-implant crestal bone levels were observed along with locally increased radiographic bone density. In addition, a cone beam computed tomography (CBCT) scan demonstrated apparent supracrestal peri-implant bone augmentation with the appearance of normal alveolar ridge contours, including the facial bone wall.
