ΣΥΜΒΟΛΗ ΣΤΗ ΜΕΛΕΤΗ ΟΡΙΣΜΕΝΩΝ ΦΥΣΙΚΩΝ ΙΔΙΟΤΗΤΩΝ ΤΩΝ ΚΕΡΙΩΝ ΟΔΟΝΤΟΣΤΟΙΧΙΩΝ

IN THE PRESENT STUDY A KINETIC INVESTIGATION OF THE CHANGES IN SHAPE OF DENTAL MODELLING WAXES AFTER THEIR MANIPULATION IN VARIOUS TEMPERATURES IS CONDUCTED. THE POSSIBILITY OF CORRELATING THESE CHANGES TO THE PROPERTIES OF FLOW AND LINEAR THERMAL EXPANSION, WHICH WERE CALCULATED EXPERIMENTALLY WITHIN THE SAME TEMPERATURE RANGE, IS ALSO EXAMINED. THREE DENTAL MODELLING WAXES WERE USED, AS WELL AS BEESWAX AND A WAX COMPOSED IN THE LABORATORY. IT WAS FOUND THAT ALL THE MATERIALS, SUBJECTED TO THE KINETIC STUDY OF DEFORMATION HAD UNDERGONE SHAPE-CHANGES, ESPECIALLY AFTER HEATING AT 27 C AND 47 C. THE FLOW VALUES MEASURED ARE RELATED TO THE CORRESPONDING SHAPE CHANGES. ON THE CONTRARY THE LINEAR EXPANSION OF THE MATERIALS DO NOT SEEM TO AFFECT THEIR BEHAVIOUR DURING THE KINETIC DEFORMATION STUDY. AT LOW INITIAL TEMPERATURES (27 C) THE DISTORTION OF THE SAMPLES IS MOST PROBABLY THE RESULT OF THE RELEASE OF INTERNAL STRESSES INTRODUCED DURING THE MANIPULATION OF THE WAX.
