Overview

'Denture retention will be a subject perplexing and perpetual until its troubles find their logical solution in understanding its physics' Hall R E Retention of full dentures; Dent. Rev. 1918; 32: 175-191.
However good a set of dentures may be, they can never be a real substitute for one's own teeth.
A lower denture interfaces with more movable mouth surfaces than an upper denture, making it more difficult to fit securely in the mandible.

  • narrow alveolar ridge compared with upper broad palatal surface.
  • the tongue gets in the way.
  • mobile mucous membrane.
  • pronounced musculature and frenum attachments, which create dislodging forces.


    • The lower denture can be troublesome indeed for many individuals.
    With Ultra Suction™ problems can be reduced to a minimum

    Why choose Ultra Suction™?

    Let's face it - How many times have you felt like "pulling your hair out" because of a stubborn lower denture problem?

    Balanced Occlusion ; Good base adaptation; Border seal; Neutral Zone; Frenum attachments: all checked and cleared ! Yet the denture keeps lifting up.

    Even worse, the resorption of the alveolar process can be so severe as to make virtually impossible the construction of stable, satisfactory dentures.


    There are many ways to approach each of the problems: Alveolar ridge augmentation, Vestibuloplasty, Implant supported overdenture etc. Often these recommendations are dismissed by patients on the basis, among others, of fear or financial factors.


  • Ultra Suction™ offers you and your patients a more affordable solution to problem dentures.


  • Ultra Suction™, together with the physical mechanisms of denture retention, will improve considerably the stability of your patients' dentures, helping them get a firm and secure feeling.


  • Ultra Suction™ offers you added value, whether mounted on a new set of dentures or during the rebase/ reline procedure.


  • Ultra Suction™ helps you establish an ongoing Patient/ Practitioner relationship by way of regular recalls for preventative maintenance.


  • Ultra Suction™ mounted on an upper denture will help your patients reduce the size of the plastic palate, improving both phonetics and taste.

    Function


    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 action tension forces at the periphery, contribute to retention, but most important are a good base adaptation and a border seal.

    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™, a specially designed profiled bar, is capable of remodelling the alveolar ridge, thus creating and maintaining a seal around that area.


    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.


    Generalities


    Ultra Suction™ can only be mounted on permanent dentures after complete healing of gingival tissues.

    Each denture must be mounted with 2 Ultra Suction™ valves on the lingual flanges or palatal aspect, between either the two premolars or between canine and premolar, depending on the case indication or at the practitioner's discretion.

    By using Ultra Suction™ denture retention system, tissue proliferation may form, to a variable degree, from patient to patient. This is necessary for creating and maintaining a seal around the alveolar ridge. However, Practitioners should discuss the subject of hyperplastic tissue and proliferation with their patients and obtain consent before fitting dentures with Ultra Suction™ system. Consent forms can be found by visiting the NZ Dental Council website or download from the DTB website or by visiting the relevant dental authority website in your country.

    For the upper denture, in general it is possible to remove the palate. Patients usually experience a feeling of comfort unknown previously.

    In some cases (particularly sensitive patients) it is preferable to wait until the formation of the new alveolar ridge, before removing the palate from the denture. We recommend beading along the new border and to encompass the tuberosity protuberances.

    Even in optimal cases with an intact ridge, it is still recommended to use Ultra Suction™ . By doing so, time taken to adapt to a new denture (lower in particular) will be reduced considerably.

    Flat ridge or resorption of the alveolar process: Allow six months on average for the formation of the new alveolar ridge, in order to obtain a satisfactory level of retention.


    Accessories


  • A specially designed profiled bar (spacer) used to create a suction chamber along the entire denture at the ridge level.

  • 2 Ultra Suction™ valves

  • 2 processing caps

  • Service key

  • Spare diaphragms

  • Instruction sheet

    Preventative Maintenance


    Although denture valves work on a simple mechanical principle, hygiene is the key to their success. Patients should run water through the visible orifices in the suction chamber and remove any food debris on a daily basis. It is strongly recommended to entrust patients who have manual dexterity with the service key, together with cleaning instructions.

    Recall Patients every six months. Open the valve covers above a receptacle of water to avoid losing the components. Remove the diaphragm; clean the valve body and the air passages. Check and remove any tartar and calculus deposits in the suction chamber and around the orifices. Replace the diaphragm with a new one if necessary and close the cover, using the key provided.

    · Saliva and oral acids have no adverse effect on the plastic diaphragm.
