From the technical side, each marginal seating has to be immaculate and each contact on each crown has to be true on the uncut model. Any excess and over contoured contact will cause shifting and improper seating, all compounded by the multiple units. Occlusal contacts should be reduced to point contacts for easier balancing in the mouth. And remember to cuspid-rise and remove all excursive movement contacts to ensure group functions. For a 30K case like this, please remember to make them a night guard to protect their investments.
Bite registration is important for a big case like this one. Establishing the correct bite is therefore very key for success. Prepping one side first and registering the bite, while having the other side as the vertical stop will prevent any shifting. Do likewise on the other side, making sure the central incisors are in centric all the time. The Prosthodontists love to establish the vertical dimension in the acrylic temps and let the patient wear them for a while to get used to them. Then they proceed to the final version using the temps as their guide. The GPs like to do it in one shot. So for this type of case to work flawlessly in the mouth, everything has to be done right the first time around. Otherwise, the back and forth continues....!

HI EJ,
Another great case! Is there any specific background, methodology or information about this case that would be worth sharing/discussing?
