Open bite

What is an Open Bite?

The open bite can have two causes: dental or skeletal. It is a very disabling type of malocclusion as it wears out the contacting teeth at the same time that it disables the non-contacting anterior teeth.


This leads to severe alterations in chewing, the function of the temporomandibular joint (TMJ), and speech. The impossibility of correctly pronouncing certain syllables is frequent, especially those that require placing the tongue behind the upper incisors. It is also common not to be able to cut food with the incisors (incisal function), being difficult for example to eat a sandwich.

Types of Open Bites

  • The skeletal open bite is treated with orthognathic and orthodontic surgery.
  • The dental open bite is treated with orthodontics, that is, placing braces and moving the teeth in such a way that we correct the occlusion. It is common to find a lingual swallowing habit, interposing the tip of the tongue between the teeth when swallowing in a way that contributes to the open bite. We will also correct this lingual habit with orthodontic appliances and speech therapy.

We often see patients with skeletal open bite treated with orthodontics only, and after some time they have a recurrence of the open bite. That is why the skeletal open bite must be treated with surgery and orthodontics, otherwise it is not stable.

Surgical Steps

In simple cases, open bite surgery consists of performing corticotomies and placing mini anchor plates to intrude the posterior teeth and thus close the open bite.

The most common treatment for skeletal open bite is orthognathic surgery. In cases in which we only want to correct the open bite because there are no more associated alterations, it can be limited to a monomaxillary orthognathic surgery either with posterior impaction of the maxilla or anticlockwise rotation of the mandible. Depending on the cause and facial features, we will decide which is the most appropriate for you.

If there are alterations associated with the open bite such as a short or long jaw (prognathism) or a long face or asymmetries, then the correction will consist of a bimaxillary orthognathic surgery. It is common to complement orthognathic surgery with a mentoplasty.
