Studying the Influence of Nano ZnO and Nano ZrO2 Additives on Properties of PMMA Denture Base

Suroor Abd Alwahab, Dr. Jaafar M. Moosa, Dr. Sadeer M. Majeed


Background and purpose: The Poly-Methyl methacrylate (PMMA) resin has been commonly used in the dental applications. This research has been aimed at the preparation of the materials which are used for manufacturing a denture with the use of a composite material, as well as observing their characteristics. Materials and methods: There have been 2 additive types (Nano zirconium oxide and zinc oxide) with various percentages of the weight (1, 2, 3, 4, and 5) % added into the PMMA resin for improving its characteristics. Results: The mix has been experimentally selected for obtaining the optimal characteristics as well as avoiding the formation of the cracks. The PMMA and di- chloromethane ratio has been respectively (20%wt) and (80%wt) for the pure samples. Conclusions: Results have shown that there has been a thermal conductivity increase, completion strength and a reduction in the roughness.
