Objectives The purpose of this study was to determine the improvement in masticatory performance and satisfaction with chewing ability in partially edentulous patients after treatment with an implant‐supported fixed partial prosthesis (ISFPP). Material and methods This prospective study included 30 patients (mean age 59 years; 17 women) with unilateral posterior missing teeth treated with one‐, two‐ or three‐unit ISFPPs and 10 healthy individuals (mean age 36 years; 8 women) with complete natural dentition to establish the normal levels of mastication. Three variables were determined at baseline and at 3‐months’ follow‐up in all participants: masticatory performance according to the median particle size (MPS) during freestyle mastication and unilateral mastication on each side, and satisfaction with chewing ability using a visual analog scale. Paired samples t test and Kruskal–Wallis test were used for intra‐group and inter‐group comparisons. Results The MPS following freestyle mastication decreased significantly at 3 months in both groups. Significant reductions of 21%, 30%, and 42% in the MPS were obtained from unilateral mastication on the treated side after treatment with 1, 2, or 3 restorative units, respectively. Three months after ISFPP, satisfaction with chewing ability improved by 40% in the treatment group. Conclusions Freestyle masticatory performance may improve slightly within three months of treatment with an ISFPP and may be similar to that of subjects with complete natural dentition. Patients may obtain a 21%–38% improvement in unilateral mastication on the treated side and a 26%–54% improvement in satisfaction with chewing ability.
