One of the greatest challenges that a restorative dentist can face is the rehabilitation of the edentulous mandible. When all teeth are removed, the mandible experiences resorption that is much more rapid and significant than the maxilla. The lack of a broad palatal surface, the muscle attachments on the mandible, and the mandibular movement make it even more challenging for the patient to comfortably wear and function with a conventional mandibular denture.
Oral rehabilitation with dental implants leads to better masticatory function in edentulous patients and there is a coincidence between patient perception and real improvement on masticatory function. It should be a primary goal for a dentist to treat complete mandibular edentulism with implant-supported overdentures.
