It is a well-documented fact that the bane of the dentist/technician relationship is a restoration that does not seat with minimal or no adjustment. Many years of experience and study have given us some insight to this dilemma — and how to solve it with more consistent prosthetics.

Ill-fitting restorations are usually due to one or more of the following:

1. Improper articulation due to a hurried lab technician.
   
2. A lack of due diligence on the part of the technician when grinding in occlusion.
   
3. An inaccurate bite registration due to the patient not biting into centric occlusion, and discrepancies between the poured model and the bite.
   
4. Incompatible expansion rate of the die stone compared to the shrinkage rate of the impression material. (This is one of the benefits of digitally captured CAD/CAM models.)

Before	After

In addition, you may have encountered a 'high' crown on full arch casts more often than quadrant models. This can be due to several things.

• When using a triple tray, the patient is biting into centric occlusion and forcing the teeth to their outer limits of their periodontal ligaments. In comparison, full arch impressions are taken in a more static position.
• Secondly, because there is more surface area on a full arch cast, there is a greater likelihood of warping, which creates irregularities that keep the models from fully interdigitating. If this is the case, the dental technician should check the casts with carbon paper after articulation to make sure there is full contact of all teeth that should be touching.
• Lastly, if the patient happens to have adequate anterior guidance, there is a tendency for the tech to make the cuspal inclinations too high, since anterior guidance is at a much steeper angle than the posteriors. The way to remedy this situation is to section the model just distal to the cuspids and remove the anterior part of the cast during fabrication.

At Trey Dental Arts, we employ a methodical, systematic approach that utilizes all of the principles above to better assure proper fitting restorations.
