Relationship between Occlusal Vertical Dimension and Tongue Pressure in Complete Denture Wearers

Data on estimating the vertical dimension of occlusion（VDO）for fabricating a complete denture based tongue pressure, which is related to masticatory and swallowing functions, are scarce. This study aimed examine changes in pressure raising or lowering VDO from most comfortable position（MCP）. Ten edentulous, including Eichner C3, patients with existing dentures（six men four women; mean age, 78.6±7.14 years）were recruited hospital setting. Twelve different height-positioning stimulus stainless-steel blocks were used（from +1 mm 6 +9 -1 -4 mm）. position （MCP）and at respective height measured. One-way analysis variance（ANOVA）and Dunnett’s test performed analyze differences VDOs. There no significant between intervals（-1 mm, p = 0.99）on MCP. Tongue decreased marginally when was raised +5 MCP（p=0.054）; it continued show decrease +6 mm（p=0.041）and +7 mm（p=0.035）from did not change significantly lowered These results suggest that may be set 5 MCP new dentures.
