Troubleshooting
Check the crown(s) on the working model and the solid model before the patient arrives.
Always compare the shade of the tooth to the requested shade tab, not a picture of the tooth.
When adjusting the crown(s) in the mouth, first check centric occlusion, then check the lateral and protrusive excursions.
After adjusting the crown(s) in the mouth, place it back on the model to see if there is a noticeable difference.
If there is a slight "rock" in a bridge, check the pontic area to see if it's blanching heavily.
If the tissue has shrunk from a recent extraction, put the bridge in place and squirt impression material under the pontic and over the bridge.
When seating bridges; after adjusting the contacts, have the patient bite on a cotton roll for a few minutes to ensure the bridge settles onto the abutments accurately.
When encountering an extremely high centric occlusion on a crown that needs to be sent back to the lab, take a new bite without the crown in place. If the crown is too far out of occlusion, leave it in place and take a new bite. The lab can then use the new bite to remount the crown, then adjust it as necessary and reglaze it.
