Purpose:
To analyze the stress distribution and displacement of the mandibular alveolar mucosa under functional impressive complete denture.
Methods:
CT images were processed by Mimics and Geomagic studio, and the solid models and 3-D finite element models were established by Unigraphics NX. 3-D finite element analysis (3-D FEA) was used to study the stress distribution and displacement on the mandibular alveolar mucosa under functional impressive complete denture and anatomic impressive complete denture.
Results:
The stress distribution on the mandibular alveolar mucosa under two types of complete denture were consistent, and arranged from large to small order as follow: alveolar process crest of molar area, alveolar process crest of anterior area, external oblique ridge and internal oblique ridge. At alveolar process crest and internal oblique ridge, the stress and Z-axis displacement of functional impressive complete denture were less than those of anatomic impressive complete denture.
Conclusions:
During masticatory period, the stress distribution on the mandibular alveolar mucosa under functional impressive complete denture is more even and more comprehensive than that under anatomic one.
