Finite Element Analysis of Restored Principal Abutment in Free-End Saddle Partial Denture.

Purpose: This study analyzed the stress distribution of restored principal abutments in free-end saddle partial dentures.

Materials And Methods: The mandibular second premolar was modeled with class II cavity restored with composite resins (Tetric N Ceram and Charisma Smile). Finite element analysis (FEA) was used to examine the stresses under 200-N static load vertically and horizontally and the results were graphically illustrated in the form of von Mises stresses.
