Question

Quizplus · Accepted Answer

The automatrix system needs no retainer to hold the band in place, which means that it is easier to use and less likely to cause discomfort to the patient. The universal retainer, on the other hand, requires a separate retainer to hold the band in place, which can be uncomfortable for the patient and may require additional adjustment and tightening. While the automatrix system does require the use of a wedge, this is a common technique used in dental procedures, and is not seen as a significant disadvantage of the system. Overall, the lack of a separate retainer is a significant advantage of the automatrix system over the universal retainer.
