Comparison and evaluation of the biting power and chewing efficiency of the all-on-four treatment concept, an implant-supported overdenture, and a traditional full denture are the objectives of this abstract study. Materials and the Methods: The study had a total of 15 individuals who were missing all of their teeth and conventional full dentures were created for each of them. Patients were separated into their own respective groups. In Group 1, patients had their full dentures replaced with an implant-supported overdenture. In Group 2, patients had their full dentures replaced with a hybrid denture that was supported by the all-on-four treatment approach. When chewing three meals of varying consistencies, the biting force was measured with a bite force sensor, and electromyographic recordings of the masticatory muscles were produced using an electromyogram. Statistical Analysis Carried Out The statistical analysis of the data was carried out by utilizing SPSS version 22.0 software. The paired t-test was used for comparing the data within each group, while the unpaired t-test was utilized to compare the data between groups. Results showed that there was a statistically significant difference between the overdenture and total denture groups in terms of biting power and chewing efficiency for the all-on-four treatment concept. The all-on-four treatment idea was seen to have the highest biting force and chewing efficiency, followed by the implant-supported overdenture treatment concept, and then the full denture treatment concept. According to the findings of the study, persons who are entirely toothless and have atrophic posterior alveolar ridges can be successfully rehabilitated with better biting power and chewing efficiency by using the All-on-four therapy approach.
