In orthodontics, a mini-screw or temporary anchorage device (TAD) is a small metal implant that acts as a fixed anchorage point to help with more complex orthodontic tooth movement.

TAD’s are typically used to aid closure of large spaces, move multiple teeth at the same time, assist with movement of teeth that wouldn’t be otherwise possible with braces alone and/or hold teeth in a fixed position if required.

Their small and clever design makes the mini-screw a simple and effective tool to treat difficult cases in a time efficient manner and is well tolerated by patients.
