INVESTIGATION OF TENSILE STRENGTH OF THREE NEW SOFT SILICONE ELASTOMERS AND COMPARISON WITH RESULTS OF PREVIOUSLY TESTED MATERIAL

The aim of the study was to investigate tensile strength of 3 soft silicone elstomers: A-soft line 30, Elite Super Soft, Bosworth Dentusil and to compare them with the results of investigation of Ufi Gel SC.48 samples were prepared - 12 of each material. The sample consisted of two parts: 20 mm long and 4 mm in diameter acrylic cylinder, and 20 mm long and 4 mm in diameter silicone cylinder. Both parts of the sample were connected with glue prepared by the manufacturer. Investigation of the tensile strength of the materials A-soft line 20, Elite Super Soft, Bosworth Dentusil was carried out on a testing machine Houndfield H5KS model THE S/N D83281and investigation of the tensile strength of Ufi Gel SC was carried out using a testing machine FPZ 10/1.The average value of the tensile strength of A-soft line 30 was 9,63 N, of Bosworth Dentusil - 7.50 N and that of Elite Super Soft - 7.29 N, while that of Ufi Gel SC was 18.61 N.Ufi Gel SC is characterised by the best tensile strength, followed by A-soft line 30, Bosworth Dentusil and Elite Super Soft. Each of the estimated material can be used in prosthodontic treatment in patients, depending on the necessity of relieving the prosthetic base.
