vertical dimension of occlusion

The vertical dimension of occlusion (VDO) refers to the distance between two selected points-typically one on the tip of the nose and another on the chin-when the teeth are in maximum contact. It is an important concept in dentistry and prosthodontics, as it affects facial aesthetics, jaw function, and overall oral health. Proper VDO ensures optimal chewing efficiency, speech, and comfort, while discrepancies can lead to issues such as jaw pain, muscle strain, and altered facial appearance. Understanding and measuring the vertical dimension of occlusion is essential for dental restorations, dentures, and orthodontic treatments.
