Alignment & dental esthetics

## Crowding

Not enough room in the arch: teeth overlap, rotate or stack to fit.

28 weeks · ~7 months

## Diastema

A visible gap between two teeth, most often the upper central incisors.

5 monthsLite Plan

## Spacing

Multiple gaps between teeth due to size or position discrepancies.

39 weeks · ~9 months

## Rotation

A tooth rotated on its own axis away from its ideal position in the arch.

Bite correction

## Overjet

Excess horizontal overlap: the upper teeth protrude beyond the lower teeth.

36 weeks · ~8 months

## Crossbite

One or more upper teeth close inside the lower teeth when biting.

![Before Crossbite](img/caso-cruzada-antes.webp)Before→![After Crossbite](img/caso-cruzada-despues.webp)After

30 weeks · ~7 months

## Open bite

The front teeth don't touch when closing, leaving a vertical gap between arches.

![Before Open bite](img/caso-abierta-antes.webp)Before→![After Open bite](img/caso-abierta-despues.webp)After

61 weeks · ~14 months

## Prognathism · AP correction

An altered front-to-back relationship between the arches, tending toward an anterior crossbite.
