An esthetic and permanent restorative materials that could be placed directly into the cavities prepared in anterior teeth would be an important contribution to dental practice and public well-being. This studies were planned to produce some
experimental composite resins with the evaluation of literatures related to manufacture processes of it. It was assumed that through this studies we wish to get some fundamental data using for the domestic production of commercial dental
composite
resins with the confirmation of manufacturing process repoted by forein researchs, and to evaluate the physical properties of it. Summarized manufacturing process used in this studies include the synthesis of BIS-GMA in laboratory, the
silanization
of
fillers, and the its incorporation into prepared BIS-GMA resin to make two paste system. As a first research project, its usefulness as a composite resin and characteristics under the some experimental conditions were evaluated by the
measurements
of
hardening time, compressive strength, diametral tensile strength, and elastic modulus, and the observation of surface using SEM.
@ES Following conclusions were drawn:
@EN 1. Concentration control of initiator and accelerator from 2% to 4% resulted the working time ranged from 0.33 minutes to 1.00 minute and the setting time from 1.66 minute to 5 minutes.
