Course Outline
This course will evaluate the various types of porcelain crowns available and bring you up to date on the current methods of cutting a preparation and taking impressions using the new material in use today. The most spectacular changes are in the materials. We no longer need to take a full mouth impression to establish the bite. This is done automatically when the impression is taken. Our impression material is more accurate and flows into the margins easier giving us a more accurate impression.

Even more impressive is the need for the doctor to take his own impressions or make his own temporaries. Both of these functions are now given to the new RDAEF (Register Dental Assistant Extended Functions). The doctor still needs to cut the preparation, but once this is done, the RDAEF can pack the cord, take the impression, and place the temporary.

I feel it is still important for the doctor to check the bite to be sure the temporary is not high. Otherwise, he may find himself coming back to the office to adjust the bite at some inconvenient hour.
