Can Invisalign fix an overbite?

Overbite is one of the common problems that patients face to make them seek professional help for correction. A deep overbite may have an impact on:

  • the force loading on the front teeth,
  • promotes wear and tear,
  • increase the chance of crown fracture and
  • may also pose restorative problems when the restoration is required.

For example, a restorative dentist may not have sufficient height between the upper jaw to the lower teeth to replace a front tooth with an implant should a front tooth is lost. Therefore, reducing the overbite through orthodontics became a crucial part of restorative treatment.

Invisalign is one of the orthodontic tools available to fix overbite issues. With proper treatment planning by your orthodontist as well as patient cooperation, an overbite can be successfully corrected. As Invisalign is a removable orthodontic appliance, it has the benefit of ease of:

  • cleaning,
  • no restriction in food choices and
  • it also more gentle on your teeth.

It is also virtually invisible and more presentable choice for adults considering correct their bite.

I would strongly encourage you to find an orthodontist who is experienced in treating complex Invisalign cases and discuss with him/her your concerns.

An overbite can mean 2 different things. To the orthodontist/dentist, it means the vertical overlap between the upper and lower front teeth.

A deep overbite means the upper and lower teeth overlap each other vertically by more than the normal amounts and it can sometimes be hard to see the lower teeth, while an insufficient overbite means the upper and lower teeth are not overlapping each other enough especially in an anterior open bite where the upper and lower teeth are not overlapping at all.

To most of my patients, an overbite may also be thought of as protruding upper front teeth, this is a common term used to describe upper front teeth that sit further in front than its lower counterpart in the horizontal dimension.

Both types of overbites whether in the vertical or horizontal dimension can be managed by the Invisalign appliance. As most of my patients refer to an overbite as protruding upper front teeth, let me address that more in detail. An overbite can be managed with Invisalign by a few ways, namely:

  1. Expansion of the arch sideways such that there is some extra space for the front teeth to be drawn inwards.
  2. Interproximal reduction where modest amounts of tooth structure between the front teeth are shaved off to create some space for the front teeth to be pushed backwards.
  3. Distalisation where teeth are moved backwards, this may involve removing the wisdom teeth to create the space for teeth to travel backwards.
  4. Elastic bite jump, this is the effect most commonly used in young growing patients where elastics are worn together with the Invisalign appliance to encourage the growth of the lower jaw and movement of the teeth to correct the increased distance between the upper and lower front teeth.
  5. Extraction. Sometimes the distance between the upper and lower teeth is too great and there is also associated lip protrusion. The best method to effect both the teeth as well as the lip is to create sufficient space for the front teeth to be retracted backwards.

It is best to arrange a consultation with your orthodontist/dentist, who can best advise you based on your clinical presentation on the treatment goals and recommend the best type of appliance for your needs.

the possible risk of permanent facial numbness.

How To Straighten Teeth: Five Ways To Correct Dental Crowding With Invisalign

With so many people opting for clear aligners for tooth straightening throughout Singapore, it is evident that Invisalign has long been an effective and trusted solution for crowded teeth. 

It's simple physics: crowded teeth require space to be created before they can be aligned. Of course, extraction is one method of creating space. But it can affect a person's facial profile.

A DoctorxDentist reader was wondering if extraction prior to Invisalign would result in a flat facial profile.

Dr Ooi Jing Liang shed light on five common ways in which tooth alignment is corrected -- including and besides extraction!
