摘要： An orthodontic aligner for changing or maintaining the position of a user's teeth comprises a mouthpiece body including a teeth receiving portion, a pressure sensing arrangement and a wireless communication and power transfer arrangement. The pressure sensing arrangement comprises a pressure chamber, containing fluid, coupled to the teeth receiving portion. A pressure sensor is arranged to sense pressure of the pressure chamber. The pressure sensor is configured to generate an output pressure signal indicating the pressure associated with the pressure chamber. The wireless communication and power transfer arrangement comprises an antenna and is configured to supply power to the pressure sensor.
