In the case that there are few remaining teeth, the occlusal relationship as well as the design of a denture is important.
A mandibular simulation model with 4 remaining teeth {Nos. 18, 22, 27 and 31 (universal tooth numbering system)} was used in this study.
The retainers were Akers clasp and cone-telescopic crown.
When the occlusal contact in lateral eccentric jaw relation was changed, the stress distribution on the abutment teeth and the displacement of the denture base were examined.
The following conclusion was obtained.
It was indicated that the occlusal contact in lateral eccentric jaw relation rather than the denture design influenced the stress distribution of abutment teeth and the displacement of the denture base.
The difference between the two retainers was not clarified when bilateral balanced occlusion was given.
It was indicated that bilateral balanced occlusion was effective even in the removable partial denture with retainer.
