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).
