Improvising the significance of vertical dimension of occlusion in patients with dentulous and edentulous condition–An update

One of the most contentious topics in dentistry has been altering the occlusal vertical dimension (OVD). When it becomes necessary to improve occlusal connections, accommodate planned restorations, and harmonize dentofacial esthetics, the OVD may need to be modified. Leonardo da Vinci made numerous observations and illustrations regarding facial proportions, specifically focusing on the lower third of the face. The calculation of the vertical dimension at occlusion involves numerous measurements of the face and body. There has been a great deal of progress in the techniques and materials used to measure vertical dimension, but little is known about an accurate assessment process for edentulous patients. Parafunctional habits that could alter the vertical dimension include abrasion, loss of teeth and molar support, and generalized attrition. It is still debatable whether or not to alter the vertical dimension of occlusion. Giving clinical criteria and subjective guidelines that a lab technician and physician should adhere to while treating patients with OVD anomalies is the aim of this paper.
