The mechanical strength of PMMA is not sufficient when a patient applies high mastication force to the denture base plate. Many fillers to reinforce PMMA was used. However, cellulose incorporated into dental acrylic resin has never been reported. In this work, two types of modified cellulose were incorporated in the heat-cured acrylic resin, and the flexural strength was investigated. The conclusion is that the addition of properly modified cellulose could have good influence on the flexural strength of dental acrylic resin. The addition of cellulose modified by 3-Methacryloxypropylmethyldimethoxysilane has increased average flexural strength and the standard deviation was satisfactory. However, Triethoxy(octyl)silane may not appropriate to achieve the intended purpose, or the modification of the cellulose by this silane itself must still be subjected to further testing. The ability to form new chemical chains between the cellulose and acrylic surfaces had a greater impact on the strength of acrylic than facilitated even distribution of cellulose.
