After analysing hundreds of thousands of whitening cases, we realised that a high percentage of failures came from ill-fitting trays at the back of the arch. This is because it can be tough to capture accurate margins on the back teeth, especially if the patient struggles with a strong gag reflex or opening their mouths wide enough for impressions.

For this reason, with the launch of our revolutionary Evo4 system, we shortened the trays (we stop them at the first molar) and also added retention attachments on the 6's to give the patient that extra retention boost, security and comfort.

Less saliva ingression, less gel escaping and a lot more comfort for your patient.

We would strongly encourage you to use them because they are vital to providing better results however if you want to receive them without the attachments, please wrote this in the special instruction box when booking your patient.
