Hi Lee Ann, I really enjoy watching these blogs and appreciate the time you all put into them. A quick question...maybe a dumb one...you mentioned polishing your preparations. Does this affect the bond strenth by reducing the micromechanical retention of the resin when the final restoration is bonded in place?

There are many articles that look at surface texture and bond strength and have not been able to correlate an increase in bond strength with a rougher texture. I have found that both traditional and virtual impression techniques are more accurate on polished preps personally. Here is one article from Pub Med so you can search for the rest if you are interested. Effects of surface texture and etching time on roughness and bond strength to ground enamel.

Thanks Lee. I am signed up for restorative design in September. Will the course be specific and provide referance to purchase the exact armamentarium that you all use? Are there any referances on the website to review prior to september? I am eager to get started. Thanks. Ian

Yes, the course is very specific and you will learn the steps in each prep design and the burs and other tools used. We actually have the bur blocks on site if you want to purchase them to take home after the course.
