Abstrakt: Background: New materials for overdenture base construction were evolved. Thus, more clinical trials are needed to validate these materials.
Objective: This study aimed to compare the difference between CAD/CAM-milled poly methyl methacrylate (PMMA), poly ether ether ketone (PEEK) and conventional mandibular implant-assisted overdentures regarding patient satisfaction and oral health-related quality of life (OHRQL).
Methods: This randomised, crossover, clinical study included 18 completely edentulous subjects rehabilitated with three mandibular implant-assisted overdentures with three different denture base materials opposing a maxillary single denture. These materials were as follows: CAD/CAM-milled PMMA, CAD/CAM-milled PEEK and conventional PMMA. Every participant first received each mandibular overdenture in a random manner. After 6 months of each overdenture use, patient satisfaction and oral health-related quality of life were assessed using visual analogue scale (VAS) and Oral Health Impact Profile (OHIP-EDENT-19), respectively, and then crossover to other groups was done. The same was repeated to the last group. Comparison of VAS and OHIP-EDENT-19 between groups was done using Kruskal-Wallis test followed by Bonferroni test.
Results: Regarding all the VAS items, there were statistically significant higher scores for CAD/CAM-milled PMMA and PEEK than conventional PMMA base except for speech, aesthetic and smell. Regarding OHIP-EDENT-19, many items revealed statistically lower problem scores for CAD/CAM-milled PMMA, and CAD/CAM-milled PEEK than conventional PMMA base except psychological discomfort, psychological disability and social disability.
Conclusion: Within the limit of this study, CAD/CAM-milled PMMA and CAD/CAM-milled PEEK were recommended as implant-assisted overdenture bases as it revealed higher patient satisfaction and better oral health-related quality of life in comparison with conventional PMMA implant-assisted overdenture.
