| Abstract | ||||
| Purpose: To compare the effect of thermoplastic resin and heat cured acrylic resin denture base materials on pocket depth and bone height around two mandibular canines supporting mandibular tooth supported over denture. Subject and Methods: Ten patients having completely edentulous maxillary ridge and bilateral canine in the lower arch were selected. Root canal treatment and preparation were performed to obtain non coping abutment with amalgam plugs that covered with over denture. Maxillary complete dentures were constructed for all patients. Patients were divided into two equal groups. Group I: received thermoplastic mandibular over denture. Group II: received conventional heat cure acrylic resin mandibular over denture. Clinical and radio graphic evaluation were performed at denture insertion , after 6month and after 9month for both mandibular over denture. Results: Statistical analysis of bone height showed that group I (thermoplastic denture) has less bone resorption than group II (acrylic denture) which was statically significant. Statistical analysis of change in pocket depth showed that group I (thermoplastic denture) has less change in the pocket depth than group II (acrylic denture) which was not statistically significant. Conclusion: Within the limitation of this study thermoplastic over denture preserved pocket depth and bone height more than conventional heat cured acrylic resin. | ||||
