Fabbri G, et al. - In this multicenter retrospective clinical study, authors compared the impacts of an increase in the vertical dimension of occlusion (VDO) in patients with fixed rehabilitations. For functional complications, results suggested statistically significant differences among the experimental groups. Researchers did not note frequent functional and prosthetic complications after the VDO increase. Mainly functional complications were seen in completely edentulous patients with posterior implant-supported rehabilitations but usually were no longer evident after 2 weeks. In terms of prosthetic complications and self-reported bruxism, no significant differences were found between the groups.
