Raising the Vertical Dimension of Occlusion

ArgenZ Anterior (ST) Monolithic Zirconia in a Full-Mouth Rehabilitation 

When treating a patient for anterior guidance, the first step begins with investigating cuspid function. For proper occlusion, the incisal edge of the lower anterior teeth should come to a vertical stop in the middle third of the maxillary anterior teeth. Patients without proper incisal occlusion frequently develop problems regarding the vertical dimension of occlusion (VDO) or the vertical separation between the jaws when the teeth are in contact.

Diagnostic Findings

The patient, a Class II Division II patient, exhibited a deficiency in VDO with evidence of a bite collapse. The patient also exhibited a decreased lower one-third facial height. Most symptoms were seen intraorally. The cuspids were misaligned and occluding without overjet, resulting in continual bruxism that can be seen in the severe wear of his lower arch, especially on the incisors. The main objective of this case was to establish a proper occlusal scheme, by establishing proper centric relation along with adequate anterior guidance, and increasing the necessary VDO to improve facial height and provide a new and brighter smile with a full-mouth reconstruction. 

Treatment Goals

• Prevent potential TMJ issues and pain with proper occlusion.
• Give overjet to establish vertical overlap and stop incisal edge wear.
• Create harmonious Curve of Spee to correct appearance of worn anteriors.
• Improve buccal corridor.
• Establish simultaneous bilateral posterior contacts.
• Improve esthetics with a fuller, more natural smile.
