How Do I Predictably Prep Second Molars?

When delivering a single crown, probably the toughest tooth we can prep for is the second molar.

There are a couple things to be aware of when prepping second molars:

1. Limited Opening

One, usually, there's a limited opening in that area, so when you are prepping the tooth, you have to give the patient breaks because you're going to have to ask them to open quite a bit.

2. Wear and Tight Neutral Zone

The second thing, which is more of a concern, is the wear in that area and also the tight neutral zone.

The problem is, that we experience at our office, is getting our patients to records. Some of the terms that we use are confusing and we lose them in the process.

Quick Tip: Incisal Embrasures & Contact Zones

In our smile design process, we have learned from Dr. Dawson how to develop incisal embrasures. And also from Dr. Dawson and the American Academy of Cosmetic Dentistry, how to develop the apparent contact zone between teeth.

So between two centrals it should be 50%, a central and lateral, 40%, and a lateral and a canine, 30%.

There are times, though, where, depending on the restorative interfaces, say, for example, two implants, we cannot create an apparent contact zone that falls in those parameters. And if we want to keep the incisal embrasures developed, as Dr. Dawson's taught us, we need to have a long contact zone.
