The effect of soft lining materials on mandibular residual ridge resorption for edentulous patient

Abstract EN

Aims: The aims were to evaluate mandibular residual ridge resorption for patients wearing lower com-plete dentures made of heat curing acrylic resin lined with acrylic soft liner and compare it with pa-tients wearing conventional heat curing dentures and compare patients satisfaction with dentures for both groups.

Materials and Methods: Residual ridge resorption was evaluated in 35 male patients through a period of 6 months by means of digital panoramic radiographs, the patients divided into three groups, first group 5 patients not used prostheses, the second group 15 patients worn conventional heat curing dentures and the third group 15 patients worn dentures lined with acrylic based soft liner, the patients also surveyed about their satisfaction with dentures.

Results: The results indicated insignifi-cant difference in the rate of residual ridge resorption between the three tested groups in 6 months peri-od.

Conclusions: There is no significant difference between conventional heat curing dentures and dentures lined with acrylic based soft lining material regarding the rate of residual ridge resorption.

Regarding denture satisfaction, most patients seem to have more comfortable denture and better chew-ing ability by using soft liners.
