What Does Class 2 Elastics Do

“in my experience, anything you can do with a class ii corrector, you can do with elastics and a compliant patient. They can be used for many different reasons, such as class 2 malocclusions, to reinforce anchorage in a case where an extraction has been done, to allow the maxillary incisors to move backwards, and to correct midline deviation and allow buccal movement of backward.

Lysle johnston december 25, 2016 at 6:28 pm your statement, “when we consider that most research has shown that functional appliances simply tip the teeth…”, underscores a divide among orthodontic researchers.

Class iii elastics hook between a bottom canine and an upper molar, from the molar to an upper canine and back to the bottom canine. Some want merely to say that. Triangle class ii elastics stretch from an upper canine to a bottom bicuspid, then from the bicuspid to a lower molar and back to the upper canine.

Since the class iii bite is just the opposite, class iii elastics aim to bring the upper teeth forward and lower teeth backward. The “class ii elastics” aim to bring the bottom teeth forward and upper teeth backward. The use of elastics to correct class ii/iii dental malocclusion can be reasonably effective with clear aligner treatment, assuming, of course, that the patient is fully compliant in wearing the elastics as directed by the treating doctor.

2) that's a question for your ortho. i asked. On the other hand, box elastics hook up to two teeth up top and two teeth on the bottom. Run elastic from upper cuspid hook to the lower 1st or 2nd molar hook, as instructed.

If you have an open bite, you may need them. When the position of one or more upper teeth are backwardly placed (called class 3 malocclusion), these rubber bands with braces help push them forward. Other types are box and triangle elastics.

Vertical elastics are usually arranged in a triangular pattern spanning from the upper canine to the lower canine and first premolar. What do class 2 triangle elastics do? In orthodontics, we call them class 2 and class 3 elastic for a reason.

Why use elastic bands with braces? A class 2 rubber bands can correct class 2 div 1 malocclusion, anterior open bite, and midline deviation. Run the elastic from the upper cuspid to the lower 1st premolar and then to the lower 1st molar to form a triangle.

To be efficient we can have patients use “class ii triangle” elastics that help bring the lower teeth forward and the teeth together at the same time. I'm sure there's a decent amount of variability, but is there an average rate of movement (e.g., x mm of correction per month) that one can expect with class ii elastics?
