Vertical dimension of occlusion

英语百科

Vertical dimension of occlusion

A patient prepared for measurement of VDO. Two stickers have been affixed to her face in order to establish the distance between the dots drawn on the stickers when her mandible is in a position that matches her VDO.  Because this patient is completely edentulous (has no teeth), her VDO measurement will be subjectively based on esthetics and phonetics.
Maxillary and mandibular record bases with notched wax rims. When placed in the mouth, these two preliminary appliances will be able to record a measured VDO because the patient will be unable to close further than the wax will allow.  The wax is built up or removed until the appropriate VDO has been established.  The two wax rims are then notched in order to allow an index of the relationship of the maxillary rim to the mandibular rim with a medium, such as Alluwax or Regisal.

Vertical dimension of occlusion, or VDO, also known as occlusal vertical dimension (OVD) is a term used in dentistry to indicate the superior-inferior relationship of the maxilla and the mandible when the teeth are situated in maximum intercuspation.
