Upper Dentures are held in place by interfacial surface tension, generally referred to as "suction" or "vacuum" and other important factors such as good base adaptation and border seal.
The same applies for Lower Dentures, but the small support surface area and the pronounced musculature in the lower jaw, reduce the secure grip of dentures, causing displacement of the denture.
Wearing dentures for a number of years causes the underlying surface to resorb, resulting in "shrinkage" of the gum. In worst cases, the "shrinkage" is so severe as to make virtually impossible the construction of stable, satisfactory dentures.
Ultra Suction™ is capable of improving both the security of wearing dentures and the pleasure of eating, drinking and talking again. Find out more...
Denture retention is, by definition, resistance of a denture to vertical movement away from the tissues.
In light of current developments and the understanding of material science and physics, there is a general acceptance among clinicians that denture retention is dependent on the control of the flow of interposed fluid and its viscosity and film thickness. Surface tension forces at the periphery contribute to retention, but most important are a good base adaptation and a border seal around some area.
However, at the first displacement, which is inevitable at some point, a gap opens along the border seal, consequently reducing the resistance to vertical movement, and subsequently lifting up the denture.
Ultra Suction™ valve is a unique denture retention system because of its clear advantages.
Ultra Suction™, specially designed profiled bar, is capable of remodeling the alveolar ridge, thus creating and maintaining a seal around that area.
Two tiny Ultra Suction™ valves are inserted into the denture, one each side. Once the denture is in place in tight occlusion (firm bite), the gingival tissues penetrate the suction chamber. The air is expelled through the valves. The diaphragms prevent its re-introduction. The pressure difference, that is, the lower pressure beneath the denture, exerts a pull and seals off the new alveolar ridge periphery.
At the first attempt to swallow, the vacuum created in the mouth eliminates any air left in the suction chamber. The result - a better fit to the tissues and an improved resistance to dislodging forces.
To remove the denture, simply lift it up.
Ultra Suction™ retention system is an affordable option for problem dentures.
Ultra Suction™ can be fitted by a Dental Practitioner on either existing dentures, or at the same time as the making of a new set of dentures.

Valves of one kind or another have been around since the early 1950's.
Although some designs performed better than others, none have ever been
developed to control the flow of air, thus regulating the pressure
beneath the denture.
Mony Paz from Biomedics NZ undertook a major redevelopment, taking into
account today's understanding of material science and the physical
mechanisms of denture retention.This revolutionary technology is
now delivered in a comprehensive mounting system.
Ultra Suction™ profiled bar has been developed to keep
tissue proliferation to the minimum necessary for maintaining a seal.
The specially formulated safe metal bar is fairly malleable, to fit any
shape and contour of the alveolar ridge.
Ultra Suction™ valves have been developed to expel the
air and control the pressure level beneath the denture, using the
specially formulated diaphragms.
Ultra Suction™ processing cap has been developed with
the dental practitioner in mind. The processing cap is specially
designed to make the self curing procedure easy and safe, preventing
damage to the valves.
The smart Ultra Suction™ service key has been designed
to double as a gauge for both depth and diameter of the valve housing in
the denture.
Ultra Suction™ system is the result of research and
laboratory development, lead by Mony Paz and Biomedics NZ team of
professionals in the fields of product development, science and
technology, dentistry and dental technology.
Ultra Suction™ is based on a simple principle:
