Orthodontics in 3 millennia. Chapter 16: Late 20th-century fixed appliances
Summary
Orthodontic advancements continue to refine Edward Angle's original edgewise appliance and its attachment methods. Innovations have evolved from metal bands to clear bonding materials, yet the core "edgewise" concept remains central to modern orthodontics.
Area of Science:
- Orthodontics
- Dental Technology
Background:
- Edward Angle introduced the edgewise appliance in 1925, revolutionizing orthodontic treatment.
- The edgewise appliance remains a foundational element in orthodontic mechanics and treatment planning.
Observation:
- Orthodontic treatment has seen significant evolution in attachment methods since Angle's original design.
- Innovations include transitions from "strap-ups" (banding) to direct bonding, and from labial to lingual appliance placement.
Findings:
- Despite numerous modifications in materials (metallic to clear) and placement (labial to lingual), the fundamental "edgewise" principle persists.
- The core concept of the edgewise appliance has demonstrated remarkable longevity and adaptability in orthodontics.
Implications:
- The enduring legacy of the edgewise appliance highlights its fundamental biomechanical principles.
- Continued innovation in attachment and material science builds upon Angle's foundational orthodontic design.

01:15Teeth
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

01:21Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
