Abstract

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.

Results: The von Mises stress distribution patterns of two different composite resins (Tetric N Ceram and Charisma Smile) were very similar in all modes of loading.

Conclusion: Composite resins with a similar modulus of elasticity in class II cavities with occlusal rest seat preparation had similar stress distributions.

Clinical significance: Nanohybrid composite resin restorations may be a possible method for preparing abutments for receiving elements of the removable partial denture (RPD).
