Sugiura T, et al. - This nonlinear finite element study was designed to examine the effects of implant configuration, bone density, and crestal cortical bone thickness on micromotion in immediately loaded mandibular full-arch implant restorations. A limited influence on micromotion was observed with implant configuration. During the healing period, avoiding cantilever loading ought to effectively reduce the risk of excessive micromotion in patients with low-density cancellous bone and thin crestal cortical bone.
