LATERAL FORCE DISTRIBUTION WITH RELATION TO THE RESIDUAL RIDGE FORM AND DENTURE DESIGN In the unilateral mandibular extension saddle-type removable partial denture prosthesis

抄録

This investigation was carried out to analyze the lateral force distribution of the unilateral extension saddle partial denture, particularly the relationship between the denture design and the residual ridge form. For this purpose, the previously reported materials and experimental equipments were used. Conclusions were as follows: (i) The lateral load distribution was highly affected by the condition of residual ridge and the denture design. (ii) When the condition of residual ridge tends to be clinically poor, with excess bone loss, cross arch-designed indirect retainer highly withstands lateral load distributions.
