Clear positioners offer a less visible alternative for correcting crooked teeth.

Firstly, a rough impression is taken then a second impression is taken with a fine material.

This gives a very accurate final impression.A ‘study model’ is made from the impression.

A number of other models are made which represent the teeth moving into position.

From these, a set of positioners are produced each one designed to move the teeth by a tiny amount.

The aligners are used in sequence and the teeth are gently moved into position.
