The Science Behind Orthodontic Treatment

Orthodontic treatment is more than just straightening teeth—it is a carefully controlled process based on biology and engineering principles. Whether using traditional braces or modern clear aligners, orthodontic treatment works by applying consistent, gentle pressure to gradually shift teeth into their ideal positions. At Broad Street Braces in Philadelphia, we specialize in providing patients with expert orthodontic care, using scientifically backed methods to create healthy, beautiful smiles.

According to the American Association of Orthodontists (AAO), nearly 4 million Americans are currently undergoing orthodontic treatment. Research indicates that properly aligned teeth can significantly reduce the risk of tooth decay, gum disease, and jaw problems over time. Additionally, clear aligners have a success rate of over 96% when used correctly, making them a highly effective alternative to traditional braces.

How Braces Work

Traditional metal or ceramic braces consist of brackets, archwires, and elastics that work together to move teeth over time. Here’s how the process works:

• Brackets: Small metal or ceramic pieces are bonded to the teeth to serve as anchors for movement.
• Archwires: A flexible wire connects the brackets and applies consistent pressure to shift teeth into proper alignment.
• Elastics (Rubber Bands): These can be added to adjust bite alignment and correct jaw positioning.

Braces work by utilizing the body’s natural ability to remodel bone. When pressure is applied, the bone on one side of the tooth breaks down, while new bone forms on the opposite side. This allows teeth to move gradually and safely without damaging their roots.

How Clear Aligners Work

Clear aligners, such as Invisalign, have revolutionized orthodontic care by providing a nearly invisible way to straighten teeth. Instead of brackets and wires, clear aligners use a series of custom-made, removable trays to gradually move teeth. The process involves:

• Digital Impressions: 3D scans of the teeth are taken to create a personalized treatment plan.
• Custom Trays: Patients wear each aligner for about one to two weeks before switching to the next set.
• Controlled Movement: Each aligner applies gentle pressure to specific teeth, gradually shifting them into place.

Unlike traditional braces, clear aligners can be removed for eating and oral hygiene, making them a convenient option for many patients. However, they must be worn for at least 20-22 hours per day to be effective.

The Science of Tooth Movement

The movement of teeth is possible due to the periodontal ligament, a network of connective tissues surrounding each tooth’s root. When pressure is applied, the ligament stretches on one side and compresses on the other, triggering cellular activity that leads to bone remodeling. This biological process ensures that teeth can shift without causing permanent damage.
