Once in a while, a newly-made crown will not fit properly onto the abutment tooth. As a result, the crown will not be fully seated between adjacent teeth. This can be exceptionally frustrating, but here is an easy way to solve the problem.
Fig. 1 - The gap under the crown on mesial and distal is checked with an explorer, and found the distal gap is smaller indicating that the distal contact is heavier than the mesial.
Fig. 2 - The crown is moved back to the disinfected lab stone model. There, the distal proximal contact is adjusted using the Lab Stone Strip a few times. The crown is placed back in the patient's mouth to check again as Fig.1. Repeat Fig.1 and Fig.2 until the crown is fully seated onto the abutment tooth with some stress.
Fig. 3 - The final proximal contact adjustment is then performed in-mouth with the Black Diamond Strip until the strip passes with light resistance. Then the crown is ready for cementation.
Fig. 4 - Occlusal adjustment is done only after cementation. When the crown is seated with complete marginal seating, there is minimal or no occlusal adjustment necessary. If occlusal adjustment is done before cementation it may be over adjusted.
