Now, if you are very well versed on doing a full metal crown, this just easy for you. With the steps that you learned there also applies here.

Step by Step

This is a metal-ceramic preparation on an upper molar tooth. The buccal shoulder margin and the occlusal reduction has been already made. If you want to review those, refer the following page:

Step 1: Check Angulation and Placement of Guide Grooves

Align your handpiece along the long axis of the crown, maintain that direction and make 3 grooves.

Don’t bring the tip too close to the prospective area of your margins. We will make the margins as we connect the guide grooves later.

Step 2: Create Lingual Chamfer Margins

Make sure to maintain the angulation of the depth grooves (that’s what they’re for).

Bring your bur in as far interproximally as you can, without nicking the adjacent tooth.

Now that the buccal and lingual walls are done, it is time to break the contacts. Proceed here to check it out.
