Abstract. The latest dental materials are tested by stretching to obtain a tensile strength parameter. The safety of restorative composite materials on the hard tissues of the tooth is ensured by mechanical parameters, so the work is promising and relevant for therapeutic dentistry. For different composites, the tensile strength parameters were obtained using the IM-4R automated tensile testing machine. The strength parameters were measured on thirty specimens where the cross-sectional area of each specimen was 5 mm. The results of measurements of the dependence of strength on the number of dental composites are represented by polynomials of the third degree; the values of approximation reliability are determined.
Keywords: tensile method, tensile strength, therapeutic dentistry, composite material, breaking machine, approximation, polynomial
