Mechanical Properties Of Denture Base After Fast Electric Polymerization And Water Bath Polymerization

Objective Compare Electric polymerization with water bath polymerization on the mechanical properties of the denture base to identify better methods of polymerization, make guidance for clinical application. Methods1.Production of80mm×10mm×4mm of denture base wax strips24, the wax strips were divided into two groups,12in each group, one group were disposed of electric polymerization, and the other with ordinary water bath polymerization method. To test the bending strength after the polymerization.2. Production of82mm×10mm×4mm of denture base wax strips24, the wax strips were divided into two groups,12in each group, one group were disposed of electric polymerization, and the other with ordinary water bath polymerization method. To test the flexural modulus after the polymerization.3.Production of78mm×10mm×4mm of denture base wax strips24, the wax strips were divided into two groups,12in each group, one group were disposed of electric polymerization, and the other with ordinary water bath polymerization method. To test the bending strength impact strength after the polymerization.4. Production of40mm×20mm×10mm wax strips24, the wax strips were divided into two groups,12in each group, one group were disposed of electric polymerization, and the other with ordinary water bath polymerization method. To test the Rockwell hardness after the polymerization. Results There were statistical signi-ficance of the bending strength and flexural modulus between two polymerization methods (P<0.05),Water bath polymerization is superior to the fast electric heat polymerization. There were not statistical signi-ficance of the impact strength between two polymerization methods (P>0.05). There were statistical signi-ficance of the the Rockwell hardness after the polymerization (P<0.05). Water bath polymerization is superior to the fast electric heat polymerization. Conclusion The mechanical properties of water bath polymerization is superior to the mechanical properties of the fast electric heat polymerization. Fast electric polymerized denture base performance test results are also in line with national standards for the pharmaceutical industry. The fast electric polymerization is an energy-saving,simple polymerization method.
