How can the position of teeth affect function?

How can the position of teeth affect function? I almost want to approach that backwards and say, "How can the position of teeth NOT affect function?"

The position of teeth is important for speaking and for enunciating sounds like our S sounds or F sounds.

The incisal edge determines how we enunciate. The incisal edge position dictates where the teeth hit on the lower lip so we can enunciate an F sound properly. If the teeth are too far apart or bumping into each other, you cannot make the F or S sounds properly, like the little kid who's lost his front teeth and wants them for Christmas. The position of the teeth affect not only our speaking, but it affects how we chew.

The position of teeth affects how we swallow and breathe.

The position of the teeth erupt into the mouth in the neutral zone, in the corridor that is dictated by the inward and outward functions of the muscles and the tongue.

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.

How to Cement a Crown in Under 20 Minutes

So here's a few tips for you to make this happen every single time.

The Golden Rule of Proportion

So as we begin to consider design as it relates to nature, it would be nice if there were some rules or formulas that would allow us to harness the power of what esthetics are all about. That would give us some predictability or a roadmap for our final design. I think it's been the Holy Grail, through mankind, to try to understand what those rules would be.

Fibonacci was a 13th-century mathematician, and he began to observe repeated patterns in nature. And what he tried to create were a series of mathematical logarithms that would give us a mathematical understanding of what esthetics was all about. The Fibonacci sequence was one of those formulas that look specifically at golden proportions.

It was a couple of centuries later that a guy by the name of Leonardo da Vinci came along. And he popularized a sketch called the Vitruvian Man. And it was based upon some work by another Italian engineer and architect, and his name was Vitruvius. And he felt as if the divine proportions seen in man ought to be what is replicated in architecture and design.
