“…This means that even when the same load is applied to both types of crowns, both the magnitude and distribution of stress within the root dentin may also differ according to material type. To date, the stress distributions of endodontically treated teeth have been analyzed with a variety of methods: finite element analysis 4,[9][10][11] , photoelastic stress analysis [12][13][14] , and loading tests 2,[15][16][17] . With finite element analysis, finite element modeling is a complex and difficult task.…”

The purpose of this study was to identify crown materials to decrease the stress concentrated at the cervical area of endodontically treated teeth. To this end, 14 extracted human mandibular premolars were divided into two groups for this study: complete cast crowns versus polymer-based crown and bridge material crowns. Both complete cast crowns (MC) and polymer-based crown and bridge material crowns (HC) were cemented with a glycidyl methacrylate-based resin cement (RC) to composite resin cores with glass fiber posts. Static loading was applied and distortion was measured with four pieces of strain gages attached to the marginal area. Findings showed that there was a large difference in distortion between crown and root in MC. On the other hand, distortions at the cervical area of crown and root were similar in HC.

“…10,29 Some papers have implicated the amount of residual axial tooth structure to be signifi cant in resisting fracture, [31][32][33] whereas other papers have excluded the width of shoulder preparation and crown margin as a signifi cant factor. 34 It does, however, appear to be a topic that needs further exploration, especially since aesthetic demands often require aggressive preparations at the margin, or previously existing buccal lesions may severely compromise the thickness of the buccal dentine wall.…”

“…Photoelasticity has been used in a wide number of dental biomechanical studies [29]. It has been applied in 2-D and 3-D studies of cavity preparation and dental restorations, to perform stress analysis [30][31][32][33], and it was also applied in the study of endodontic posts [33,34]. Standlee et al [34] have performed a comparative analysis of three types of posts regarding design, insertion, length, and ability to transmit forces to supporting structures.…”
