Abstract

Abstract: Objective: To prepare a soft lining material with high elastic on the basis of excellent characteristics of eucommia ulmoides gum. Methods: The basic formula was used based on the existing formula of elastic eucommia ulmoides gum and medical rubber. The current formula was modified according to the specific requirements of denture lining materials. Corresponding eucommia ulmoides gum composite soft denture liners were constructed and delivered to physical and mechanical property tests. Subsequent modification to the formula was made according to the results of tests. The "modification and test" procedure was repeated, until favorite formula was established. Results: When eucommia ulmoides gum and butadiene rubber blend ratio was 80∶20, after adding gas phase nano-silica with 7PHR and appropriate content of fillers, eucommia ulmoides gum composite soft denture liners could present favorite properties. Conclusion: The final formula of eucommia ulmoides gum composite soft denture lining material was established by the "modification and test" procedure.
