Maximum Protrusion: CAD/CAM Is “Magic”!

Panthera Sleep

by Béatrice Robichaud

One of the most common bite techniques used by sleep dentists is taking the bite impression at 70% of the patient’s maximum protrusion. Some will argue that it is better to take it at 60%, and some at 50%, but that is not the point.

With the help of CAD/CAM technology, there is an altogether better way: When you take a bite registration, the software can use the provided information to calculate what is between your bite and the centric point of your patient without needing any additional information.

For example, with a 70% bite, it is possible to know everything that happens between zero protrusion and up to the 70% maximum protrusion of the patient. What happens beyond that, however, will remain a world of mystery. In other words, if you provide the maximum protrusion of your patient when you take the impression, the software will be able to know everything from zero up to that maximum, which solves the problem of unknown areas.

Does this mean that we have to start the patient’s treatment at maximum protrusion? Not at all. One of the benefits of using CAD/CAM is that it can provide you with all the information needed to plan the best possible treatment for your patient.
In other words, CAD/CAM could be called “magic” software, since it brings to sleep appliances what surgical guides have brought the dental implant industry: better treatment planning.
