Further Theoretical Insight into the Mechanical Properties of Polycaprolactone Loaded with Organic–Inorganic Hybrid Fillers

Abstract

Experimental/theoretical analyses have already been performed on poly(ε-caprolactone) (PCL) loaded with organic–inorganic fillers (PCL/TiO2 and PCL/ZrO2) to find a correlation between the results from the small punch test and Young’s modulus of the materials. PCL loaded with Ti2 (PCL = 12, TiO2 = 88 wt %) and Zr2 (PCL = 12, ZrO2 = 88 wt %) hybrid fillers showed better performances than those obtained for the other particle composition. In this context, the aim of current research is to provide further insight into the mechanical properties of PCL loaded with sol–gel-synthesized organic–inorganic hybrid fillers for bone tissue engineering. For this reason, theoretical analyses were performed by the finite element method. The results from the small punch test and Young’s modulus of the materials were newly correlated. The obtained values of Young’s modulus (193 MPa for PCL, 378 MPa for PCL/Ti2 and 415 MPa for PCL/Zr2) were higher than those obtained from a previous theoretical modelling (144 MPa for PCL, 282 MPa for PCL/Ti2 and 310 MPa for PCL/Zr2). This correlation will be an important step for the evaluation of Young’s modulus, starting from the small punch test data.

Metal Posts and the Effect of Material–Shape Combination on the Mechanical Behavior of Endodontically Treated Anterior Teeth

“…Experimental methodologies and CAD-FE modeling have always played a crucial role in the analysis of the mechanical behavior, stress and strain distributions in different fields [11,[23][24][25][26][27]. As widely reported, the use of a dental post with a high modulus material alters the biomechanical behavior of a restored tooth [4,12,13].…”

FE analysis of conceptual hybrid composite endodontic post designs in anterior teeth

“…The important role of CAD-FE modeling and experimental methodologies to analyze the mechanical behavior, stress and strain distributions, has been recognized in different fields [29,[37][38][39][40][41][42]. The biomechanical behavior of a restored tooth is altered if a dental post with high modulus construction material is employed and vertical root fractures generally occur [3,34].…”

Flexible organic–inorganic hybrid bioceramic for bone tissue regeneration

“…The inorganic/organic hybrid materials prepared by sol-gel technique have high surface-to-volume ratio and nano-scale phase domains. [14][15][16][17] The important thing is to select an appropriate organic phase, which must have functional groups to react with organosilanes and must be compatible with the sol-gel process. Unfortunately, many biodegradable polymers cannot be easily introduced in the sol, but PBSu has been found compatible in the sol-gel process.…”
