#14 crown cementation

Female patient presented to the dental office for #14 crown cementation. I learned that the crown that was fabricated from the lab was a butt margin porcelain crown which meant that the margins were covered in porcelain so that the metal didn’t show on the buccal or the lingual margins of the crown. Also, the crown had a kaitlyn loop on it with a dental floss attached to it so that it’s easier to handle/remove the crown when modifications are needed. I learned how to remove the temp crown with a crown removal forcep without placing so much force. In addition, once the temp crown was removed, the temp cement was removed from the tooth and the permanent crown was tried in with a piece of articulating paper on the sides to check for interproximal contact on both mesial and distal sides. A slight adjustment was made interproximally and then a bitewing x-ray was taken to check for the marginal fit. After the x-ray was analyzed and confirmed to be adequate, the kaitlyn loop was removed with a bur. I learned that if you put Vaseline on the interproximal surfaces of the crown especially on the middle and occlusal third, then it will be easier to remove the excess cement around the embrasure of the crown. The assistant mixed the cement mixture and I observed the cementation of the #14 crown. The excess cement was removed with floss and the patient was biting on the cotton rod for 12 minutes for the cement to set. After that, an extra-oral picture was taken to show the patient how it looks in her mouth.
