In the classification of the 6 Andrews occlusion keys, the diastemas are located at number 5 and this indicates that in addition to occlusion disorders, it sometimes involves compensations in the mesio-distal width of the teeth that make up the arch.

Diastemas are the gaps between teeth that are sometimes found in the adult teething stage but are more common in infant teeth.
They are usually treated with transparent aligners, closing the upper arch (where the most common cases occur).

There may also be a case that makes complete closure impossible due to the position of the lower arch, which is why they will be camouflaged away from the most medial area and camouflaged towards posterior sectors.

Other times, these diastemas are found in both arches (Andrews occlusion key 5), so we recommend that it be controlled by the orthodontist in order to solve more complex cases.
