Which instrument is used to remove elastomeric ligature ties?

The instrument specifically designed for removing elastomeric ligature ties in orthodontic procedures is the orthodontic scaler. This tool has a thin, pointed end that allows for precision in accessing tight spaces around brackets and wires, making it ideal for disengaging the elastomeric ties that hold the archwire in place. The orthodontic scaler facilitates the removal process without causing damage to the teeth or orthodontic appliances, ensuring a thorough and careful approach.

Other instruments mentioned, such as a scalpel, typically serve different functions—primarily cutting or incising tissue, which is not necessary when simply removing ligature ties. Forceps are generally used for grasping and manipulating larger objects or tissue, not for the precise task of removing ligature ties. The dental mirror, while useful for visibility during various procedures, does not have the necessary design or function to remove ligature ties effectively. Therefore, the orthodontic scaler is the most appropriate choice for this specific task in dental assisting.
