Compliance in orthodontics has generally decreased in the past 10-15 years, which led to the development of many so called "Non-compliance" treatment devices. Most of them do still need compliance in consecutive stages of ongoing treatment, however. In this context, upper-and lower molar distalization-and bite jumping devices like Pendulum, Herbst, Mara and others are discussed. On the other hand, as compliance is still a main factor for treatment success, ways to improve it are shown.
