title: Subapical osteotomy to correct dental implant malpositioning and vertical ridge deficiency: a clinical report.
abstract: This clinical report describes a subapical osteotomy to correct vertical ridge deficiency and malpositioned maxillary anterior implants. A 37-year-old woman with a noncontributory medical history presented with the chief complaint of an unesthetic implant-supported prosthesis. The maxillary left central and lateral incisors were restored with metal ceramic restorations. Gingiva-colored porcelain was fabricated to compensate for severe vertical and horizontal soft tissue deficiency. The patient was dissatisfied with the esthetics associated with the restorations and soft tissues since she presented with a high smile line and gingival display. Under general anesthesia, a subapical osteotomy was performed. The implant and ridge segment was coronally repositioned to correct the ridge deficiency. The surgical procedure and postoperative healing were uneventful. The surgical outcome was stable for a follow-up period of 3 years. The subapical osteotomy provided a satisfactory clinical outcome in managing a severely deficient residual ridge and malpositioned maxillary anterior implants as an alternative treatment to other surgical approaches.
