The main goals of the present study to improve the function and aesthetics of the maxillofacial prosthesis, these were benefits for the patient’s quality of life. Throughout determine the appropriate percentage of cellulose Nano-fibers placement that improve the silicone used in the maxillofacial area’s mechanical and physical characteristics. Methods: Overallof 75 samples were created by placement of cellulose nanofiber (CNF) in various wt. percentages to VST50 (RTV) platinum silicone elastomer. Five groups, for each group which have 15 samples were created from the study samples. Four groups were made with varying percentages of CNF (0.5%, 1%, 1.5%, and 2% by weight), whereas one control batch was prepared without the inclusion of cellulose nanofibers. According to the conducted tests, each group was subsequently separated into three subgroups which included testing for tear strength, surface roughness and shore A hardness (n=5), An analysis using descriptive statistics was used to examine the data (mean, standard deviation, and bar chart representation). Results: The average value of shore A hardness, tear strength of the 0.5% by weight CNF strengthening group raising significantly as comparative to the control group. Whereas surface roughness non-significant raising. In contrast to the other parameters of the reinforcement groups, which were severely degenerated. Conclusion: It was determined that placement 0.5% by weight CNF to maxillofacial silicone substitution material can enhance its mechanical qualities.
