Evaluation of efficiency of complete dentures using bps, lecutonite & acrylic materials: An original research

Introduction: Type of materials used in fabrication of denture base has an effect on dimension during denture base material processing and other factors related to clinical use. The study aims were to assess the efficiency of complete dentures made using bps, lecutonite & acrylic materials. Material and Methods: Ninety patients were selected to construct complete dentures with bps, lecutonite & acrylic materials denture base materials. They were randomly divided into three groups: group 1, patients with bps; group 2, patients with heat curing acrylic resin fabricated by injection moulding technique and conventional methods; and group 3, patients with lecutonite. The dimensional changes were assessed using digital caliper. Results: After the twelfth month, injection moulding acrylic resin had significantly the highest dimensional change followed by the lecutonite. There were no significant differences in the dimensions between the three types of denture base materials at normal mouth temperature, while, after hot tea drinking at 45∘C, the dimensional change was significantly the highest in cobalt chrome metallic denture base group. Conclusion: BPS denture base has stable dimension compared to denture bases fabricated of lecutonite, acrylic resin but it was more affected by altered mouth temperature
