How to decide the increase of VDO

VDO?Can I increase it? Can the patient tollerate it? How much?
These are the most common questions, when clinicians start a 3STEP. And the answer is: YES, YOU CAN increase, but let’s decide how much increase for each patient, and let’s start from the articulated models.

A laboratory planning first, which will be test driven in the mouth with the 3STEP.


  • Analyse the relationship among anterior contacts, increase VDO and posterior space
  • Be familiar with the anterior stop
  • Use the anterior stop in the mouth as a anterior jig to reconfirm the bite registration at the increased VDO
