PurposeThe aim of this study was to evaluate bite force and oral health impact profile (OHIP) in completely edentulous patients rehabilitated with two different types of denture bases.Patients and methodsA total of 26 patients were selected from outpatient clinic, Removable Prosthodontic Department, Al-Azhar University. For each patient two types of complete dentures were made: (a) a heat-polymerizing hard Polymethyle-methacrylate (PMMA) and (b) thermoplastic PMMA. Bite force were evaluated 1 month and 6 months after denture insertion. Oral health-related quality of life was measured after 6 months of denture use using modified OHIP scale for edentulous patients. The data were statistically analyzed using statistical package for the social sciences V21 software.ResultsAfter 6 months of denture insertion, the bite force with a thermoplastic PMMA was better than that of heat-polymerizing hard PMMA with statistically significance difference. After 6 months, the OHIP for thermoplastic PMMA recorded better values more than a heat-polymerizing hard PMMA.ConclusionA thermoplastic PMMA denture was found to significantly has better maximum bite force values and OHIP after 6 months of denture use as compared to heat-polymerizing hard PMMA complete dentures.
