Comparison of bombyx mori l. Fibroin coatings on the mechanical properties of collagen membranes

Background: Most of dental implants are accompanied by guided bone regeneration (GBR) procedures. Collagen membrane which is the most widely used type of membrane in the GBR procedure has the disadvantage of not having antimicrobial properties, old bone formation, easy to tear, and soft so that it does not maintain the dimensions of the augmentation area. Bombyx mori L. fibroin has good mechanical properties and has the potential to be used as a pharmaceutical material that is biocompatible, antimicrobial, and stimulates bone growth. The aim of this study was to analyze the effect of Bombyx mori L. fibroin coating on the mechanical properties of collagen membranes.
Method: The samples consisted of the control group (group A) and the treatment group, the collagen membrane was coated using the Bombyx mori L dip-coating fibroin technique, namely group B (1 time coating process), group C (2 times coating process) and group D (3 times the coating process). Statistical analysis used one-way ANOVA (p<0.05).
Result: The results showed that the average tensile strength of the negative control group was 2.62 MPa, the 1-coated group was 4.51 MPa, the 2-coated group was 5.45 MPa, and the 3-coated group was 1.41. The significance value of ANOVA was 0.000, the post hoc test results showed that there were significant differences in all test groups with a significance level of 0.005
Conclusion: It is concluded that coating Bombyx mori L. fibroin on collagen membranes increases the physicomechanical properties of tensile strength.
