Edward Hartley Angle was a very important American dentist. Many people call him the "father of American orthodontics." Orthodontics is a special part of dentistry that focuses on fixing teeth and jaws. Angle wanted to make sure everyone learned the same way. He spent his life making dental teaching more organized. He believed that having a standard way to teach was vital for the profession.

Angle studied how teeth fit together when a person bites down. He used the word malocclusion to describe teeth that are not in the right spot. He created a system to group these different types of teeth. He looked closely at how the large back teeth, called molars, met. He said that normal teeth should follow a smooth, curving line. If the top and bottom molars fit a certain way, the teeth would be healthy.

Angle created many tools, called appliances, to move teeth. One tool was the Pin and Tube Appliance from 1910. It used gold and platinum bands to hold teeth. Later, he made the Ribbon Arch Appliance in 1915 to help teeth rotate. He also created the Edgewise Appliance in 1925. This tool allowed teeth to move in three different ways. He worked with an artist to make sure smiles looked beautiful too.
