Dental Aligners & Malocclusion: What Cases Can Aligners Treat?

Many potential patients asked whether Eon Aligner can help treat their malocclusion. The answer, for the most part, is yes. Eon Aligner can treat almost all types of malocclusions. Let’s take a look at these malocclusions, what they mean and what can happen long term if they are left untreated:

Increased overjet

Typically, there is a space of 2 mm between your top front teeth and bottom front teeth. But sometimes, the top front teeth are too protruded or flared out, which is called an increased overjet. If left uncorrected, an overjet can cause biting or eating difficulties, speech problems, lack of full closure of lips, buck teeth appearance and increased chance for dental trauma etc. 

Gap teeth

Many times, spaces exist between your teeth that do not serve any purpose. Rather, they cause more harm to the teeth by allowing bacteria and food particles to accumulate in these spaces. Spacing between teeth looks unattractive in a smile, and may also lead to some lisps or speech issues. In addition, food gets stuck in the spacing, leading to bacterial growth and the eventual development of chronic gum disease. 


When the jaws are too small or the teeth are too big, there is insufficient space for the teeth to line up correctly. Hence, they appear crowded or overlapping with each other. Maintaining proper oral hygiene with crowded teeth is often difficult as food tends to get stuck between the teeth, leading to an increased risk of developing gum disease and dental decay. Often, the gum tissue adjacent to the crowded teeth appears inflamed because of bacterial accumulation, which may lead to pain, discomfort, and bad breath.

Deep bite

Ideally, the upper front teeth overlap about 30% of the lower front teeth. You have a deep bite when this overlap is more than 30% or the upper front teeth completely cover the lower front teeth. A deep bite can affect your facial profile and proportions, making your smile unattractive. Most often, you experience an improper bite on your back teeth that can lead to chronic jaw pain, discomfort and headaches. Additionally, if your lower teeth are continuously in contact with the roof of the mouth, you could have mouth sores or ulcers (traumatic deep bite).

Cross bite

A correct bite is when your bottom teeth set sits comfortably inside your upper teeth set. However, in certain cases, a single tooth or more than one bottom teeth sit outside your top teeth, which is called a crossbite. You can have a single tooth crossbite, a crossbite on your back teeth (one side or both sides), on your front teeth or on all your front teeth (underbite). 

Whatever the type of crossbite, it usually affects your face aesthetics and causes chewing problems. In addition, you can experience tooth pain, pain in the jaws, lisps or slurred speech, and even headaches. 

Open bite
In atypical cases, your bottom teeth and top teeth do not contact each other, or there is vertical space between them, even when the mouth is closed. This space can exist between your front teeth or back teeth, and affects the attractiveness of your smile.  Most often, people face issues in biting, chewing food, and speech. Rarely, an open bite can cause problems in your jaw joint, snoring, and chronic headaches. 

Implants, Bridges, and Restorative Work

If you have had implants or a significant amount of restorative work performed on your teeth, it is best to check with your doctor about how your teeth movement can be done. The implant or bridge cannot be moved since they are fixed restorations but our Eon-certified doctor can plan the teeth movements around them to get a beautiful new smile.
