Differences between Aqualizer, AquaSplint mini and FreeBite

We offer a large selection of air and water cushions: the water-filled Aqualizer, AquaSplint mini and FreeBite balance, as well as the air-filled FreeBite air.
What are the differences in terms of design, manufacture, material, comfort, variations, durability and customer feedback?


Production method, material and concept

The Aqualizer consists of two welded halves of nylon foil. This lies flat and can only be deformed relatively slightly, so that the crease through which the water cushions lie between the rows of teeth is bent in and not permanently formed. Punched edges on the foils are relatively sharp and are therefore partly covered with foam strips to reduce irritations of the oral mucosa.

The AquaSplint mini and FreeBite are formed from one piece. This creates a dimensionally stable shell from a single casting without weak points due to welds and edges. The disadvantage of this production method is that it is not possible to make the cover as thin-walled as possible with a film. The Aqualizer therefore creates a softer bite impression than the AquaSplint mini and FreeBite. With the FreeBite, the inherent elasticity of the shell is part of the concept, as it is specifically designed to relieve temporomandibular joint compressions and chronic tension in the masticatory musculature. This is achieved by a specific shape that extends further back to the back teeth and has a slight wedge shape to form the first contact on the back teeth. The elastic cover then gives way so that the bite blocks form on the posterior teeth from the back to the front during bite. The focus here is on the support in the bite on the back teeth in order to relieve temporomandibular joints as efficiently as possible. Air and fluid behave differently as fillers, the former supporting resiliently, fluid more firmly and balancing.

However, the shape of the FreeBite can also be disturbing in cases where the first contact between the rows of teeth is on the back teeth anyway. A softer water cushion, such as the Aqualizer, or a shorter one, such as the AquaSplint mini, may be more comfortable to wear.


Wearing comfort

The Aqualizer is held between the rows of teeth from the outside by the pressure of the cheeks. In the AquaSplint mini a stainless steel wire is inserted, which can be bent in such a way that it remains on the tooth row by itself. Nor does it have any sharp edges, as they occur with an Aqualizer. The FreeBite is guided between the cheeks and tongue and lies loosely and playfully between the rows of teeth. It is possible that the FreeBite is initially perceived more as a foreign body, because it is designed to actively stimulate a conversion of the muscles. Therefore, it is recommended to start with a shorter wearing period and to extend it slowly. Initially, the Aqualizer or AquaSplint may be easier to wear through the night.


Shape variations, heights and durability

There are two different forms of FreeBite. The "CMD" version is designed to relieve the temporomandibular joints, is thinner overall and has a weak wedge shape. The "CCD" variant is thicker overall with a stronger wedge shape and is intended for deep occlusions, especially if hyperlordosis of the neck or head is present.

The AquaSplint mini is only available in one form. If you can handle it, you're done with the selection. On the other hand, it is both an advantage and a disadvantage that the Aqualizer is now available in three different shapes, each in three filling levels. So you have both the advantage and the agony of choice!

The Aqualizer loses water over time, which is not the case with the AquaSplint mini and the FreeBite balance. In all of them, the shell can be cut through by sharp edges on prostheses or teeth, which can happen in the first few days. If the AquaSplint mini has survived this without damage however, it can last for months, while with the Aqualizer it can also happen, that the weld seam slowly peels up and then suddenly opens after a few days.


Customer feedback

Customers most often complain about the need to buy the Aqualizer frequently due to its relatively short shelf life and sharp edges. With the AquaSplint mini, on the other hand, complaints usually concern the bite block that some people find too firm or that the customer cannot cope with bending on the wireframe.

With the FreeBite it is occasionally reported that it is pressed on. This should be avoided as far as possible, as it tires the chewing muscles. This usually happens when you try to wear the FreeBite for long periods of time. However, the form has a special stimulating effect and it is recommended that you get used to it step by step. If you also need to wear something at night, the combination of an Aqualizer for the night and a FreeBite during the day has proven itself during the acclimatisation phase.
