Is Invisalign effective in correcting an open bite?

Can Invisalign fix an anterior Open Bite? rnInvisalign was first introduced in 1997 by two Stanford University students that invented the first complete clear aligner system. At this point in time correcting an open bite with Invisalign was not recommended. As the years passed, a better understanding of how modified Clear Aligners can direct the necessary force in a predictable manner allowed for more orthodontic corrections such as open bite to be possible. Although Invisalign has made a lot of progress over the years, it is still limited when it comes to more complex cases such as posterior open bite. In this case, Invisalign may not be the best option. It is always best to consult with an experienced orthodontist in order to determine if Invisalign can fix your open bite. How can Invisalign correct an Open Bite? rnIn order to correct an open bite Invisalign trays are designed and programmed by an orthodontist to fix an open bite. This process may include all of the following: rnExtrude the anterior teeth making sure the teeth align with your smile line. rnIntrude the posterior teeth with possible wisdom teeth extraction in some cases. rnMini-Implants may be required in the upper posterior area if a more posterior intrusion is needed. rnUse rubber bands of rubber bands inducing a counterclockwise mandibular rotation[iii].rnInterproximal reduction (IPR) may be used if the tooth varies in size and shape.​rnHow long does it take for Invisalign to correct an Open Bite?rnThe treatment time will depend on the age of the patient and also the size of the open bite. Adult patients with a moderate open bite (2-3 mm) will have a time frame of approximately 18-24 months. Younger patients with the same moderate open bite will take between 12-18 months. If an open bite is much bigger ( more than 4 mm) the use of mini-implants will be required and the length of treatment will be 24-28 months or more. What are the advantages of using Invisalign over braces to close the Anterior open bite?rnBetter vertical control. Traditional braces tend to have an extrusive effect on the back molars. This side effect is better controlled with the Invisalign since each tray has a minimum thickness of 0.5 mm, rnLess root resorption. Correcting anterior open bites might be associated with various degrees of root resorption. Because the Invisalign trays are removable, this will give the front teeth some break to relax and minimize the chances of getting root resorption.rnControl bad habits that might contribute to the open bite such as thumb sucking and tongue thrust.rnAbout how many trays are needed to fix the anterior open bite?rnPast research has revealed that an average of 73 clear aligners are needed to get the open bite fixed. However, this number can vary from patient to patient possibly ranging from 40 to 100 trays. Invisalign & Surgery For Open Bite TreatmentrnIn very complicated open bite cases, surgery can become the only solution. Braces are required before surgery is performed to align and straightened the teeth to ensure the open bite is corrected properly. Only a specialized orthodontist with years of experience using Invisalign offers the option to use aligners instead of braces in this unique circumstance. To recap this post, Invisalign can be used to correct open bites with advancements in Invisalign technology. A patient should always consult with an experienced orthodontist, preferably one that has many years working with Invisalign. The orthodontist will be able to determine if Invisalign can be used to correct open bites on a case-by-case basis.
