Cephalometric Approach to the Occlusal Vertical Dimension Reestablishment

Case Reports in Dentistry, 2014
The occlusal vertical dimension (OVD) refers to the length of the face as determined by the amount of separation of the jaws. Its determination is important for the manufacture of restorations.

Relationship between bridging and dimensions of sella turcica with classification of craniofacial skeleton [PDF]

, 2018
Purpose: In orthodontics, it is essential to determine the craniofacial skeleton pattern (class I, II, III) for planning treatment. Sella turcica bridging that is seen on lateral cephalometric radiographs is considered as a normal finding.
