title: [Comparative analysis of unilateral removable partial denture and classical removable partial denture by using finite element method].
abstract: BACKGROUND
  Various mobile devices are used in the therapy of unilateral free-end saddle. Unilateral dentures with precise connectivity elements are not used frequently. In this paper the problem of applying and functionality of unilateral free- end saddle denture without major connector was taken into consideration.
  
  
  OBJECTIVE
  The aim was to analyze and compare a unilateral RPD (removable partial denture) and a classical RPD by calculating and analyzing stresses under different loads.
  
  
  METHODS
  3D models of unilateral removable partial denture and classical removable partial denture with casted clasps were made by using computer program CATIA V5 (abutment teeth, canine and first premolar, with crowns and abutment tissues were also made). The models were built in full-scale. Stress analyses for both models were performed by applying a force of 300 N on the second premolar, a force of 500 N on the first molar and a force of 700 N on the second molar.
  
  
  RESULTS
  The Fault Model Extractor (FME) analysis and calculation showed the complete behaviour of unilateral removable partial denture and abutments (canine and first premolar), as well as the behaviour of RPD under identical loading conditions. Applied forces with extreme values caused high stress levels on both models and their abutments within physiological limits.
  
  
  CONCLUSIONS
  Having analyzed stresses under same conditions, we concluded that the unilateral RPD and classical RPD have similar physiological values
