矯正装置 (kyōsei sōchi) refers to orthodontic devices used to correct misaligned teeth and jaws. These devices can include braces, retainers, and aligners, which apply gentle pressure to gradually shift teeth into their proper positions. The primary goal of 矯正装置 is to improve dental health and enhance the appearance of a person's smile. By addressing issues such as overcrowding, gaps, and bite problems, these devices help ensure better oral function and can prevent future dental complications.
