The purpose of this study was to investigate the influence of different occlusal contact locations in mandibular molars on occlusal bite force, bite force distribution, and the resultant coronal microstrain.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods<\/jats:title>\n                    <jats:p>A split\u2010mouth, cross\u2010sectional study was planned. Twenty\u2010nine participants aged between 20 and 40 years with healthy dentition were studied. A 100\u2010\u00b5m articulating paper and an iTero digital scan were used to locate occlusal contacts in mandibular molars. The control group included samples with only functional cusp contacts. The test group included samples with functional and nonfunctional cusp contacts. Upon sample categorization, the bite force at the maximum intercuspation position was evaluated in the mandibular molar region using a Tekscan B201 FlexiForce sensor for all patients. In contrast, 14 patients were evaluated by T\u2010Scan 10 Novus to check occlusal bite force distribution. Subsequently, buccal and lingual coronal microstrain after a bite load was evaluated in all the selected mandibular molars using strain gauges.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The occlusal bite force (N) and the bite force distribution values (%) of the test group and control group were not significantly different (\n                      <jats:italic>p<\/jats:italic>\n                      = 0.96; 0.09). The lingual coronal microstrain (150.96 \u00b1 15.84 \u03bc\u03b5) in the control group was significantly lower than the buccal coronal microstrain (253.36 \u00b140.65 \u03bc\u03b5) (\n                      <jats:italic>p<\/jats:italic>\n                      = 0.001). The test group had significantly higher lingual coronal microstrain (356.00 \u00b1 42.43 \u03bc\u03b5) than the buccal coronal microstrain (286.68 \u00b1 44.01 \u03bc\u03b5) (\n                      <jats:italic>p<\/jats:italic>\n                      = 0.001).
