around the retention cham- ber and the air channels were thoroughly cleaned (Fig 46). The valve covers were opened over a receptacle of water to avoid losing the components. The valves were cleaned and the diaphragms replaced. Patients were in- structed to clean their den- tures and the valves on a daily basis. Patients who had manual dexterity were given the service key, together with spare diaphragms and were instructed to perform routine maintenance in between the biannual visits (Figs 47-51). Discussion Ultra Suction system appears to increase considerably the re- tention of complete dentures in both clinical observations and statistical findings. Their reten- tive capacity is superior to that of conventional dentures. The decrease in the rate of applied negative force by 10mmHg per 15 seconds, attributed to the design of the diaphragms, sug- gests that we may have a more tissue friendly denture than we first thought. It is well known that the supporting tissue is subject to -80mmHg under con- ventional maxillary dentures, which caused an increase in epithelial width in the palate and attached gingival, and a de- crease in the epithelial width in the alveolar mucosa4 in most, if not all, complete denture wear- ers. The response is directly re- lated to the functional demands of the tissue. In view of this documented evidence, it would be responsible to conclude that Ultra Suction’s negative force is less invasive that that of con- ventional dentures.
