Orthodontic archwire stop made of shape memory alloy
A recently granted patent (Publication Number: US11992385B1) discloses an orthodontic archwire stop designed for placement on an archwire. The stop features a C-shaped body with a unique composition of shape memory alloy, including two portions with different metallic elements and phase change temperatures. The first portion has a base alloy composition with a specific ratio of metallic elements and an austenitic finish temperature, while the second portion differs in composition and phase change temperature, providing enhanced functionality for orthodontic applications.
Furthermore, the orthodontic archwire stop includes innovative features such as a hook for attaching orthodontic elastics or appliances, a rib on the inner surface for deformation when in contact with the archwire, and a design that allows for easy transition between open and closed positions without the need for mechanical input. The composition of the shape memory alloy, particularly in relation to the ratios of metallic elements and phase change temperatures, contributes to the overall performance and durability of the orthodontic archwire stop. These unique characteristics make it a valuable addition to orthodontic tools and devices, offering improved functionality and efficiency in orthodontic treatments.
