Objectives: A major aim of dental treatment amongst others is the restoration of function when masticatory performance is impaired due to tooth loss. The most promising and preferred approach among treatment methods offered to totally edentulous patients is to provide the patient with implant-supported complete arch-fixed prostheses (ISCAFp). Material and Method: patients rehabilitated in the prosthetic dental clinic with ISCAF- Dp and TBCAFDp were included in the study. In addition, individuals with ND were selected as the control group. Each group consisted of 12 individuals. The sieving analysis and surface EMG method was used to evaluate the chewing performances. Results: There was no statistically significant difference in the chewing direction and the EMG results obtained during chewing cycles between patient groups (p<0.05). However, the interaction of the sieve-patient group was found to be statistically significant (p<0.05). Conclusion: patients using ISCAFp can apply chewing forces without hesitation due to the limitations of the control mechanism. Therefore; for ISCAFp, the fabricating procedures should be followed to distribute the force evenly. Objective evaluations of the mas- ticatory function and the performance of implant-supported dentures will help clinicians for the best treatment planning for their patients.
