The Deep Bite Challenge: Is the Story Different for a Lingual, Labial or Aligner Patients?

with Professor Omur Polat-Ozsoy


The deep bite malocclusion can have negative effects on the facial and smile aesthetics.

Moreover, it can cause several oral health concerns like damage to the teeth, gingiva and temporomandibular disorders.

Therefore, the correction of a deep bite is crucial for both dental hard and soft tissues.

Deep bites can be treated using various methods, and the treatment decision depends on several factors but the most important factor to be considered is the incisor display of the smile.

Depending on the aesthetic expectation of the patients, the choice of the treatment can be performed using the conventional labial technique, the lingual technique or aligner orthodontics.

Each method has its own biomechanical rules and challenges.

This presentation will compare treatment of the deep bite malocclusion between lingual, labial and aligner orthodontics and will focus on the biomechanical differences of the 3 methods.
Several cases will be discussed with comparative outcomes.
