Abstract:

 Aim: This study evaluated the masticatory efficiency and maximum bite forces of metal-ceramic versus polyether-ether ketone (PEEK) and composite fixed full-arch prostheses in completely edentulous patients. Materials and methods: 8 participants (4 males and 4 females; mean age 58±3.8 years) with complete edentulous maxillary and mandibular ridges underwent computer-guided surgery to receive six implants in both arches. Six months later, patients were randomly divided into two groups: Group 1, comprised of four patients, received fixed full-arch metal-ceramic restorations (control group), while Group 2, also consisting of four patients, received fixed full-arch PEEK frame restorations veneered with composite resin teeth (study group). Three months after the prosthesis delivery, chewing efficiency was assessed for both groups using a two-colored mixing gum test, measuring hue deviation (HD) of the mixed color pixels in the gum via View Gum# software after 5, 10, 20, and 30 chewing strokes (CS). Maximum bite force was evaluated using a bite force transducer. Results: Group 1 demonstrated significantly higher masticatory efficiency for all chewing stroke counts than group 2. The highest HD (indicating the lowest chewing efficiency) occurred at 5 CS, followed by 10 CS, then 20 CS, with the lowest HD observed at 30 CS. After three months, group 1 displayed a significantly greater maximum bite force than group 2. Conclusion: Within the limitations of this study, metal-ceramic restoration is recommended for restoring complete edentulous patients with fixed full-arch implant-supported prostheses, as it is associated with improved chewing efficiency and maximum bite force compared to PEEK-composite prostheses.
