Increasing Skill with Precisely Defined Objectives | Primary Planes

Of the many unique concepts in PTC’s, I believe one of the most interesting is the primary plane.

I first heard of primary planes when I was introduced to PTC in 1983. I thought it was a very clever idea/concept, but I must admit that for nearly 15 years I really didn’t understand the true purpose of it.

Purpose of Primary Planes

Creating primary planes is one of the first steps in contouring wax or ceramic restorations.
