The bite is the most stable when all teeth touch evenly while the jaw is in a harmonious position with the jaw joints. Before teeth are treated for a cosmetic dental procedure, I analyze the bite in this harmonious position.
This analysis can be done by using an articulator with mounted stone models of the teeth. I mount the models using the recorded bite with the jaw joints in alignment. Then I determine if the bite is even and in harmony. Most dentists and orthodontists do not take this extra step before treatment.
If the bite is not in harmony with the jaw joints, there is a greater risk of the new treatment breaking. There is also a risk of natural teeth wearing down or fracturing. Often times it is possible to bring the bite into harmony before the cosmetic work is done. This is ideal for long lasting cosmetic dentistry.
