The primary objective of complete denture prosthesis for patients with severly resorbed residual alveolar ridges includes the positioning of functional and esthetic dentition in harmony with the normal neuromusculature. The presence of severe resorption in the mandible makes it difficult for the clinician to attain adequate retention and stability. This results due to the absence of adequate bony hard tissue and presence of dislodging musculature at the same time. The neutral zone approach guides the arrangement of artificial teeth as well as the contour of the polished surface of the dentures, in a way that these are in harmony with the forces from the tongue on one side and the lips and the cheeks on the other side. The neutral zone is a stable zone where the net force from either side of the musculature is nullified. Hence the denture remains stable. This articles describes the management of a severely resorbed mandibular ridge using the neutral zone concept.
Key words : Alveolar ridge, neutral zone, overdenture, prosthetics.
