Wires move teeth by applying pressure that triggers bone remodeling.
The process of moving teeth with wires during orthodontic treatment is a carefully orchestrated biological phenomenon. Here's a detailed breakdown:
-
Archwire Pressure: The core mechanism involves the archwire, which applies a gentle, consistent force to the teeth. According to provided information, the pressure exerted by the archwire is key to tooth movement.
-
Bone Remodeling: This sustained pressure initiates a process called bone remodeling.
- On the side of the tooth receiving the pressure, bone cells called osteoclasts are stimulated to break down the existing bone structure. This process is known as bone resorption.
- On the opposite side of the tooth, where tension is created, bone cells called osteoblasts are activated. These cells build new bone to support the tooth in its new position.
Process | Cell Type | Action | Location |
---|---|---|---|
Bone Resorption | Osteoclasts | Breaks down existing bone structure | Side receiving pressure |
Bone Formation | Osteoblasts | Builds new bone to support tooth | Side experiencing tension |
In essence, the wire doesn't force the tooth through the bone. Instead, it stimulates the body's natural bone remodeling process to gently guide the tooth into the desired position.
