Side open bite after treatment

Updated: Jun 16, 2021

After treatment, a laterally open bite can be seen. Why?


It would be superfluous to mention that you are not the only doctor who is facing exactly this question. Many doctors face exactly this problem in the course of treating their cases.

At the end of any Clear Aligner treatment, the posterior teeth should have a stable occlusion with comprehensive vertical support. Nevertheless, in some patients or female patients, a laterally open bite becomes visible during treatment, especially after 6 months in the advanced treatment process.

Imagine that the acrylic layers rest on the posterior teeth day and night. This fact alone gives rise to the tendency of intrusion of the posterior teeth, resulting in a temporary posterior open bite.

From a scientific point of view, there are several factors that can lead to this.


1. your patient suffers from bruxism

2.the overjet or overbite are not yet stable

3.Not enough attachments on the posterior or posterior segments to prevent the intrusive movement.
