There are different kinds of rubber bands, and today we're going to look at Class 2 rubber bands. Used in cases where there is excessive overbite, or over jet. They clip from the upper canines to the lower molars. Patients can use just their hands, or they can use a small tool that aids them in hooking the rubber bands. It goes from the lower molar to the upper canine. They should be worn 24 hours a day, except when eating and brushing. Immediately after eating or brushing, they should be replaced. Class 3 elastics are used in cases where there is an under bite, or there is a lower jaw protrusion. These rubber bands hook from the upper molars to the lower canines. Patients can use just their hands, or they can use a small tool that aids them in hooking the rubber bands. Again, they go from the lower canines to the upper molars. They exert a force that's pulling the lower teeth back up and under the upper teeth. They are to be worn 24 hours a day, except eating and brushing. Immediately after eating and brushing, they should be reinserted. These are called triangular elastics. They are very commonly used to finish cases. They go from the upper canine, to the lower canine, to the lower pre molar. Their function is to close down bites. They form the shape of a triangle. Again, they go from the upper canine, to the lower canine, to the lower pre molar.
