INTRODUCTION

The oral mucosa (denture bearing mucosa) is not created to be covered or to carry prosthesis. Deviation from nature always results in changes in the tissues, which may be pathological.

Before the construction of new prosthesis, the supporting structures must be in a healthy condition.

A thorough examination of the mouth prior to construction of complete dentures is necessary to identify potential problem areas. Potential problem areas can be made with the aid of mounted diagnostic casts, intraoral radiographs and panoramic radiography.

A treatment plan calling for surgical correction should be made after alternate nonsurgical approaches have been considered and evaluated.

A nonsurgical approach to treatment when surgery is contraindicated or preservation of the height of bone is essential. Fabrication of new dentures using established prosthodontic would decrease occlusal loading   over the affected area and distribute forces more to the primary support areas like the mandibular buccal shelf.

Reduction of the width of the occlusal table together with maximum denture base extension would reduce forces on the supporting tissues chronic. Temporary resilient liners can be used.
