What is the 3 plane of occlusion?

Answered by Randy McIntyre

The occlusal plane, my friend, is an interesting concept in dentistry that I’ve come across in my experiences. It’s basically an imaginary surface that is related to the cranium, and it’s a theoretical plane that touches the incisal edges of the incisors and the tips of the occluding surfaces of the posterior teeth.

Let me break it down for you. Imagine you’re looking at a person’s mouth from the side. The occlusal plane is like a line that you can draw that connects the biting edges of the front teeth and the cusps of the back teeth. It’s kind of like a reference point for how the teeth come together when you bite down.

Now, I should mention that the occlusal plane isn’t always perfectly flat. It can vary from person to person due to factors like tooth shape, jaw alignment, and individual differences. Sometimes, the occlusal plane may be slightly tilted or curved, depending on the person’s bite.

In dentistry, understanding the occlusal plane is important because it helps us determine the proper alignment and positioning of the teeth. When we’re making things like dental restorations or dentures, we want to ensure that the teeth come together correctly and that the forces of biting and chewing are distributed evenly.

To determine the occlusal plane, dentists use various methods and tools. One common technique is to use an articulator, which is like a fancy hinge that mimics the movement of the jaw. By mounting models of the patient’s teeth on the articulator, we can simulate their bite and determine the position of the occlusal plane.

So, in a nutshell, the occlusal plane is a theoretical surface that relates to the alignment and positioning of the teeth. It’s not always perfectly flat, and it’s important in dentistry for ensuring proper bite and tooth function. Pretty fascinating stuff, if you ask me!
