There are three different Aqualizer models: Aqualizer Slim, Aqualizer Ultra and Aqualizer Mini.
The Aqualizer Slim is slim shaped with improved comfort. The side wings are shorter. This reduces irritation of the tongue and gum and is suitable for more sensitive patients. The Aqualizer Ultra has slightly wider side wings. It is used for average sized mouths. Because of the wider fit and wider side wings, this model can be worn in combination with brackets during orthodontic treatment.
The Aqualizer Mini is suitable for children, youth, small-sized jaws or when molar teeth are missing.
