Abstract
Self-curing resin for tooth crowns is widely used in clinical practice. It has been applied to temporary restoration for reconstruction of occlusion, resin splint in splint therapy, which is a method for temporomandibular disorder, and formation on the occlusal plane to maintain and restore the occlusal relation of the plate denture.
However, since the durability of self-curing resin is lower than other dental materials, it is inadequate to maintain and keep stability of the occlusal relation, vertical dimension, durability against attrition and resistance to abrasion due to mechanical friction.
Properties is needed. To improve the hardness and abrasion resistance, cyclophosphazene monomer was combined with 4 commercially available self-curing resin monomers and physical properties were compared.
1. Hardness increased as the amount of the cyclophosphazene monomer was increased.
2. Abrasion resistance improved as the amount of the cyclophosphazene monomer was increased.
3. These results show that the combination of the cyclophosphazene monomer with commercially available self-curing resin monomers improves hardness and abrasion resistance.
