Orthodontics – General crowding and deep bite

Opis slučaja

The patient came to us with general crowding in the upper and lower dental arch and deep bite. The space to align teeth with an orthodontic appliance, any appliance, can be achieved by one of three ways. By expanding the dental arches, by minimally narrowing the teeth via air rotor stripping method and teeth extraction. Even though the expanding of dental arches sounds like the best option and it’s the easiest to do, there are consequences to moving the teeth outwards too much. A long-term consequence is the withdrawal of bone and gums on the teeth which were moved which, from a medical standpoint, puts them in a worse position than they were at the start of orthodontic treatment.

By completing an exhaustive analysis (model analysis, orthopantomogram, LL craniogram) it was calculated that enough space can be obtained by slightly expanding the dental arches along with narrowing the teeth by air rotor stripping. Air rotor stripping is a safe method, long used in orthodontics. Many studies were made on the long-term effects of this method and no adverse effects were found on the teeth whose width was reduced by less than 0.3 millimeters on a single plane. Although this is a very small amount, in each dental arch there are 14 teeth with two planes which can be narrowed using this method. This way you can get up to 8.4 millimeters of space per arch.

In the place of the second lower left premolar, which was lost before starting orthodontic treatment, space was left for prosthetic rehabilitation of the lost tooth. The case was finished in ideal occlusion in which the upper incisors lean against the lower ones, the middles of the dental arches align, the upper canines sit behind the lower incisors in ideal class I and the deep bite was corrected.
