Management of severe undercuts in fabrication of complete dentures.

The use of a RDB material has been discussed in the management of patients presenting with severe undercuts in the maxillary and mandibular edentulous jaws. In edentulous patients there are instances when a patient would feel more comfortable and hence prefer RDB material in spite of its lack of longevity. In general, dentures with resilient materials will last for about two to three years. However, in the first case discussed here, three sets of dentures have been fabricated during the last 12 years and each set lasted for four years. One reason why this patient had such success with her dentures could be her attention to good oral hygiene. Patients with RDB materials should be recalled regularly, preferably every three months, to check the condition of the RDB material and the oral mucosa. Good judgment must be used in selecting patients. Resilient denture base materials should not be used as a panacea.
