Surgical and prosthetic correction of malposed maxillary implants: a case report.

ABSTRACT

This case report presents a patient who underwent a major correction of malpositioned implants. Two implants were previously placed in a 30-year-old woman to replace the maxillary right central and lateral incisors without any attempt to reconstruct the alveolar and soft tissue defects. This resulted in a significant esthetic problem. The position of the implants was successfully corrected via the mobilization of a bone block in which the implants were maintained. The bone block was then fixed in a predetermined optimal position. After fixing the bone block, gaps were filled with Bio-Oss and covered with a membrane. Nine months after bone healing, a periodontal technique was used to improve soft tissue esthetics. The final result was achieved with the combination of bone surgery, soft tissue management, and progressive adaptation of implant-supported crown restorations.
