Implant supported overdenture for the atrophic mandible.

A long-term denture wearer exhibited advanced alveolar bone loss, resulting in an atrophic mandible. Symphyseal bone height was 10 mm. The inferior alveolar nerve and mental foramen were close to the crest of the mandible. The symphyseal region was available for endosteal implant placement. Patient was an 83-year-old white male who was medically compromised. Anticoagulant therapy was stopped and INR evaluated prior to implant surgery. With the help of computerized tomography, four Nobel Biocare Tapered TiUnite narrow platform implants were placed anteriorly between the mental foramina. An implant-supported mandibular overdenture was fabricated. Locator attachments provided retention and stability for the prosthesis. This helped improve the patient's quality of life.
