However, calcium hydroxide has several weaknesses which cause many researchers to look for alternative ingredients that come from nature. Mechanical Properties of Dental Materials - Dr. Nithin Mathew Compressive Stress • Compressive stress occurs when 2 sets of forces are directed towards each other in the same straight line. 388 413 207 207 432 207 638 207 713 282 713 713 563 563 563 337 15 0 obj 812 337 337 300 300 315 500 900 812 900 500 300 850 22 22 500 Estadual Paulista-UNESP Araraquara, SP, Brazil The highest values of compressive strength were recorded for resin composite (334.23 ± 15.92 MPa) when compared to resin-modified glass ionomer (169.5 ± 20.98 MPa) and conventional glass ionomer (78.78 ± 13.3 MPa). compressive strength for dentin of 43,100 psi; Stanford et al.1 gave a value of 50,400 psi; and Tyldesley3 published a value of 38,800 for the breaking stress. 343 433 433 899 899 1063 1063 562 523 523 541 541 112 758 612 541 4 nano-hydroxyapatite and nanotitanium to improve its compressive strength.
