Cusp deflection meaning
WebCuspal deflection depends on bending stiffness; thus, it directly depends on the product between the second moment of area and the Young’s modulus. The mean width value of our premolar cusps (Table 2) was 6.47 mm, significantly lower than that of the aluminum cusps (8 mm) adopted by Kim et al. Moreover, the shape of the dental cuspal cross ... Weband cause 63% of the cusp strength loss ; As a result, possibility of the deflection of cusp is increased (12,13). When comparing MO or DO against MOD fillings ,the shrinkage strength of the composite polymerization can cause lower negative deflection in cusps because minimum amounts of restorative material are required (14–17) .
