Objective: Restoration of maxillofacial defect is comprehensive process, variety of materials have been used but none of them have, the aim of the study effect of reinforcement of VST-50F (RTV) maxillofacial silicone elastomer with (2mm) polyamide fibers before and after oxygen plasma treatment on tear strength and surface roughness. Materials and Methods: Seventy specimens have been prepared and divided into two groups (35) for the conducted test: tear strength and surface roughness, each group then subdivided into four subgroups according to the concentration of the fibers (0%, 0.5%, 1%, 1.5%) where n= 5. Results: The samples were tested and the data were analyzed with a descriptive statistical analysis, one-way ANOVA, post-hoc tests (Bonferroni, Games-Howell). results showed significant increase of tear strength with 1.5% plasma treated PA-6 fibers and significant increase of surface roughness with both types of fibers and all concentration. Conclusion: We conclude for that 1% and 1.5% plasma treated PA-6 fibers with (2mm) length can improve the mechanical properties and proceed for the main study.Keywords
