Elastics are a key part of orthodontic treatment and learning how to remove and replace them is an important part of the process for most patients undergoing braces or clear aligner treatment. Before your orthodontist sets you on your journey to a perfect smile, they will make sure you understand all there is to know about this aspect of your treatment as the need for elastic wear will vary greatly from one person to another.
As the type and size of elastics you are wearing would be recorded, you can usually pick some up from the patient reception desk at the practice or even have them mailed to you if this is more convenient.
It is best to talk to your orthodontist if you're experiencing difficulties with your elastic bands to ensure your treatment progresses as expected. However, you can also see if there are any behaviours you can adjust to keep your elastics in tact. This can include removing them while eating and brushing your teeth, and trying not to open your mouth too widely.
I got vertical elastics (canine to canine) and I'm wondering what would happen if I just don't wear them? as I cant deal with the pain and discomfort so what would be best to do? like if I dont wear the elastics will my teeth still come in place it will just take longer?
Hi Chloe, if you don't wear your elastics then your teeth won't be directed to come down into the position you want and it will likely extend your treatment significantly. However, you should speak to your orthodontist about your concerns and any issues you're having with your treatment to ensure you get their specialist opinion.

A Washington State woman claims she closed her tooth gap in 44 days using $5 worth of hair elastics. She posted six videos to YouTube chronicling the process, garnering hundreds of comments and more than 100,000 views.
With the demonstration of anchorage from the lower arch to the upper, and with the use of elastics, Angle changed his opinion from extraction to non-extraction, which was to be manifested in his teachings in his career thereafter. He showed that elastics were tied in, and demonstrated that molar correction with inter-maxillary elastics could be achieved in three months [1,2].
Different factors influence the effects of an elastic on a tooth: such as, the site of application, the distribution through the periodontal ligament, the direction, length, diameter, and contour of the root, the alveolar process, the tooth rotation and health, age, and above all the co-operation of the patient. The force produced by the elastics on a tooth or teeth does not depend only on its magnitude.
We first recommend the adoption of one size of wall thickness, which is small enough to fit under the wing of a bracket, and so for this study we chose the 5 oz elastics, and decided to vary only the length of the elastics in the selection (Figure 1).
Different patterns of rest position were studied by Ricketts , and the average was 3°, which is important in order to evaluate the reciprocal position of both the maxillary and mandibular arches. In addition, we considered the angle between the elastics and the lower arch wire at different distances (Figure 3).
One factor which does seem to be common is the sizing, which has been graduated in 1/16 inch increments. Thus, a graduation exists, such as: 1/8 or 2/16, 3/16, 1/4 or 4/16, 5/16, 3/8 or 6/16, 1/2 or 8/16; which are the usual sizes. For simplification the elastics were labeled #2,#3,#4,#5, #6 etc., referring to each sixteenth of an inch.
For these reasons, we suggest pulling the 5-oz elastics to four times the size of their outer diameter, in order to have a greater range of lengths, with a constant force at the same distance for one week, and with the proper distalization force, considering the following formula:
We calculated the distances present from the lower molars to the canines in our sample, and we simulated all of the conditions in class II at the beginning of the correction, during the correction, and after the correction, even in the cases where (for orthodontic needs) four premolars were extracted (extraction cases). Identifying the correct distance is the starting point for a correct choice of elastics.
We found that the decay rate in one week is about 25%, so the latex elastics can be employed for one whole week maintaining 75% of their pull, which will produce a constant force for a long period, as advocated by many authors [4,7,10]. For this reason, it is advisable to ask to the patients to change their elastics every week (Figure 9 and Figure 10).
Studying the parallelogram of force, you can see that the vertical pull over the treatment period will average to about one-third of the oblique pull, while two-thirds of it is horizontal; so, the longer the distance between the ends, where the elastic is attached, the more horizontal the pull becomes. For this reason, it is desirable to apply the elastic from the lower second molar, when it is present, to the upper canine. Thus, you may reduce the vertical component, which results in the extrusion of the upper arch (as an undesirable side effect).
Class II correction is one of the most common conditions, especially in the Caucasian race [30,31]. Different strategies of therapy were carried out, but inter-maxillary traction made by elastics is nowadays the simplest strategy, and one of the most efficient, if correctly used . Elastics can be also used for different reasons: To reinforce anchorage in a case where an extraction has been done, to allow the maxillary incisors to move backwards, to correct midline deviation, and to move the lower denture forward. The side effects of Class II elastics should be considered before using them .
The common side effects, from the improper use of elastics are: The steepening of the occlusal plane, the extrusion of the lower first molar, the flaring of the lower incisors, and the extrusion of the upper incisors. The first three effects could be avoided by the use of skeletal anchorage, or cortical anchorage. Skeletal anchorage is achieved by using temporary anchorage devices (TADs), which are small screw-like dental implants made of a titanium alloy. As the name implies, they are temporary, as they usually only remain in place during some months of the treatment, and then they are removed. They are placed through the cortical bone in order to become an application point for the elastic traction . Cortical anchorage is a biological method to obtain a valid application site of elastics during Class II correction. When the roots engage the cortical plates, the action will become static and a tooth root becomes a point of resistance, and hence it becomes an anchor for an undetermined period of time. The most efficient tool in order to obtain cortical anchorage is the utility arch. Compact bone not only offers resistance to the tooth movement, but, conversely, it can be used for anchorage, and is recognized and employed to this advantage. This is accomplished by the teeth situated behind the compact elements of bone, so that the pressure of the root is almost in direct contact with the bone, and incapable of easy backward resorption .
The extrusion of the upper incisors, with the consequent decreasing of their torque, and the deepening of the bite, produces a gummy smile. This could be avoided by using sectional mechanics, that consist in the cutting of the upper archwire at the level of the canine; thereby excluding the upper incisors from the traction made by the elastics. The two sections obtained could be used to transfer the force applied on the canine directly to the upper molars. Furthermore, the sections could be activated with an intrusion bend that produces 50 g of force, that will prevent the extrusion of the canine as given by the vertical component of the elastic pull.
As we have seen, in order to correct the class II malocclusion, we need 120 g of force to move the upper molar distally. Hence, we chose 5 oz elastics and we stretched the #3,#4,#5, #6 elastics to four times the outer diameter (about five times if we consider the inner diameter), and this produced the same force, which was about 235 g, with the different lengths of elastics. This amount of force must not scare, as by subtracting the correction factors (vector and decay) that we consider in our formula, we have obtained the effective distalization force that we wanted.
Dr. Kothari has the knowledge and training to bring out the best in your smile and if the approach involves orthodontic rubber bands, the 914 Orthodontics team will help you use them as efficiently as possible. We offer a variety of orthodontic treatments including Invisalign and braces in Tarrytown, Sleepy Hollow, Briarcliff, Ossining and the surrounding area.
Background: Two types of orthodontic elastics exist based on their material, latex and nonlatex, each of which has different properties in clinical use. Some of the differences include their initial force and force degradation over time. This study was conducted to compare the force changes in both materials.
Methods: Medium-force orthodontic latex and nonlatex elastics from American Orthodontics (AO) and Ortho Technology (OT) of lumen size 1/4 inches and 3/16 inches (total sample 110 elastics) were submerged in artificial saliva (pH 6.7) and incubated for 48 hours. Then, the elastic force was measured at the following time intervals: initial, 1, 3, 6, 12, 24, and 48 hours. Orthodontic latex and nonlatex elastics from AO and OT were analyzed using Fourier-Transform Infrared Spectroscopy and energy-dispersive X-ray to know the chemical bond structure and elements. 59ce067264
