The Use of Root Form Implants in Overdenture Treatment for the Atrophic Mandible: A Clinical Report
Four short root form implants were inserted in an atrophic mandible and the case restored with a lower connecting bar and an overdenture, opposing a complete maxillary denture. Root form implants were selected, as opposed to a subperiosteal implant in this case. The patient had a favorable medical history, appeared healthy, did not smoke, drink, or do illicit drugs, and had good bone quality.

Preoperative radiographs. Severe mandibular residual ridge reduction is evident.
