Abstract | ||||
Purpose: This clinical study aimed to evaluate the retention quality of conventional heat-cured poly methyl methacrylate (PMMA) compared to Poly Ether-Ether Ketone (PEEK) maxillary single dentures. Materials and Methods: Ten participants were eligible having completely edentulous maxillary arches opposed by class I Kennedy mandibular arches. Every patient received two maxillary single dentures fabricated by two different materials and techniques utilizing a crossover design. Each patient was provided with a single maxillary conventional PMMA denture fabricated by the conventional technique (group I) and a PEEK single maxillary denture fabricated by CAD /CAM technique (group II). The force-meter was implemented to measure the retention of the maxillary single dentures at time of denture delivery (T0) and then after 3 months of insertion (T3). Every denture was subjected to a slowly increasing vertical load until it was totally out of place (that was for 5 times at 10-minute intervals). The average retention of maxillary single dentures of both groups was analyzed using Paired t-test. Results: CAD/CAM PEEK maxillary single dentures showed statistically significant higher mean retention values than conventional heat-cured maxillary single dentures at time of insertion (P = 0.031),also, after three months post insertion (P = 0.04). Conclusions: CAD/CAM (PEEK) maxillary single dentures offered significantly higher retention than that of conventional heat polymerized single dentures. CAD/CAM (PEEK) maxillary single dentures could be a suitable choice when retention improvement is required. Recommendation: More long-term studies of variant evaluation methods are thus required to validate the results of this study. | ||||
