The effect of mandibular overdenture to manage trauma to anterior maxillary residual ridge.

Residual alveolar ridge changes brought on by bone loss has always been one of the great problems related to denture prosthesis. The changes beneath denture bases has been investigated and the agreement on individual difference on the rate of bone resorption has been proven. Clinical experience and studies gave great knowledge of the prosthetic factors which influence bone resorption. It has been proved that excessive pressure, and shearing forces are the main causes of ridge changes. Very common is the problem associated with patient having only natural mandibular anterior teeth occluded with complete upper denture. The anterior maxillary region is the weakest area in the upper arch to resist stress when the lower natural anterior teeth occlude anterior to the basal support; trauma is inevitable.
