ABSTRACT
PURPOSE: To compare the stress distribution of supporting tissues in Atwood level 3 alveolar bones under the mandibular complete dentures with and without denture adhesives. METHODS: Photoelastic models of epoxy were fabricated according to the standard Atwood level 3 edentulous model. 1.5 kg force was vertically applied on the bite force loading device. After stress frozen, photoelastic model slices in posterior teeth area were observed and analyzed. RESULTS: When using denture adhesives, stresses distributed more adequately in the buccal and lingual side and the force of alveolar crest increased remarkably. CONCLUSIONS: To those with Atwood level 3 alveolar ridge and complete denture, denture adhesives can not only increase stability but also prevent local pressure under uneven stress distribution.
