What type of tie is typically used when repositioning teeth with elastic?

1. Wire tie

2. Kobayashi tie

3. Rubber tie

4. Chain tie

The correct answer is: Kobayashi tie

The Kobayashi tie is a specific method used in orthodontics for securing elastic materials to brackets during the process of repositioning teeth. This technique involves using a thin tie that allows for the elastic to be anchored effectively, providing the necessary force to move teeth into their desired positions. The unique design of the Kobayashi tie contributes to better control of tooth movement while maintaining patient comfort. In contrast, wire ties are generally utilized for securing archwires to brackets but do not provide the same specificity for elastic placement. Rubber ties could imply the use of elastic itself but typically refer to the elastic ligatures used on brackets, which do not specifically denote a repositioning tool. Chain ties, while useful in certain treatment plans that require continuous application of force across multiple teeth, are not the direct method for repositioning when focusing specifically on the elastic technique. Understanding these distinctions is crucial for effective orthodontic practice and ensuring that the right tools and methods are used for each specific task.
