Bite lift techniques in orthodontic treatments

At this time of the year, from September to November, with the beginning of classes and the return of the holidays, it is very common to begin orthodontic treatments . For this reason, in this article we want to talk about a technique widely used in orthodontics: the bite lift .

The lifting of the bite is a technique that is used to unblock the occlusion, prevent the upper teeth from colliding with the lower teeth or achieve a greater transversal benefit of the arches. It is usually used in orthodontic lingual, vestibular and even aligners treatments.

The bite releases, can be made both in the anterior and posterior regions and the choice of the ideal place should be analyzed case by case by the orthodontist in the planning of the case.

Below, we will detail more about each type of bite lift.

Rear Bite Lift

This lift is made on the occlusal side of the upper and / or lower molars and premolars. Its objective is to open the bite, causing the de-occlusion in the previous region. For a correct preparation, it is recommended to make bilateral levantes preferably in the second molars.

A very common way of performing posterior lifts, proven by many orthodontists, is using photopolymerizable monocomponent resin with fluoride release . Among the most used options are the 3M Trasbond Plus or the Blue Resilience from Ortho Technology .

According to orthodontists consulted, the Resilience highlights its ideal consistency, easy handling and that does not stick to the antagonist or wear easily, facilitating work and saving time.

In the following image, you can see the application of this sticker.

This type of levant is indicated, especially for dolicofacilae or mesiofacial patients, patients with anterior crossbite or with a lower third of the augmented face (prevention of extrusion of the posterior teeth).

 

The photopolymerizable resin can remain in the mouth for approximately 8 months. In the cases in which the bite releases need to remain more than 8 months, it is recommended to perform the second molars in the alternative way, removing it after a few months.

Bite Lift Previous

This type of lift is performed on the palatal surfaces of the upper central incisors, causing a posterior bite opening. This allows the extrusion of the molars and premolars, leveling the curve of the lower Spee. Consequently, it is possible to improve the overbite in cases of deep bite.

For this type of lift, you can use prefabricated bite lifts in composite, mini molds to fill with composite or make them directly on the tooth with composite for restorations. In the following image we observed an anterior bite lift with Bite-Builder from Ortho Technology :

This treatment is indicated especially for brachifacial or mesofacial patients, patients with deep bites or with cross-bite porteriores.

 

To consider:

  • They must remain in the mouth until the installation of the steel arches.
  • It is recommended to join the upper anterior teeth from canine to canine to prevent the opening of diastemas in this region.
  • In patients with increased overjet, when the top of the anterior teeth becomes impossible, the preparation of the levant should be made in the canines.
