Evaluation of physical properties of demineralization dentine material membranes through tensile strength tests

Background: The process of bone remodeling requires quite a long time, which is between 6-8 weeks. During the process, the proliferation of fibroblast cells occurs simultaneously. The process of fibroblast cell proliferation takes place more quickly when compared to bone remodeling process. Both processes that occur simultaneously can be at risk of failure of the process of bone remodeling, due to the intervention of fibroblast cells in the direction of bone defects so the bone that formed are not perfect. To prevent this intervention a Guided Bone Regeneration (GBR) is needed. GBR must have good mechanical strength to be able to withstand the pressure during the process of fibroblast cell proliferation. GBR which has been widely used in the medical field is made from porcine pericardium, this results in the use of GBR which cannot be used universally because it is not halal. For this reason, a Demineralized Dentine Material Membrane (DDMM) was made as an alternative to GBR. DDMM is made from demineralized bovine dentine. 

Purpose: Proves that DDMM has good mechanical strength. 

Methods: Three DDMM samples were tested using a Dynamic Mechanical Analyzer (DMA) to determine the value of tensile strength. 

Results: In the tensile strength test found significant differences in the DDMM group against Jason Membrane (p = 0.01; p <0.05). 

Conclusion: DDMM has good strength in holding a force.
