“Influence of different cavity designs and restorative protocols on fracture resistance and induced strain of weakened thermo-cycled maxillary premolar teeth: An in-Vitro study”

Abstract

Restoring a weakened tooth can be challenging, Mesio-occlusal-distal (MOD) cavities in premolars could complicated the treatment due to the creation of elongated cusps and loss of marginal ridges, increasing its susceptibility to fracture. Evolution of esthetic dentistry through technological advances in restorative materials and adhesive systems has drawn great attention to the usage of adhesive materials for conserving and reinforcing the weakened teeth. Special concern should be taken on restoring MOD cavities, as it has been reported that inadequate restorative therapy is the major factor for failure of such cases.(127,126) Proper cavity preparation design, the restorative material used, and the interactions between material, restored teeth
