Overview

In vitro study reveals resin cement type significantly alters shear bond strength to 3D-printed resins, indicating silane treatment provides limited bonding benefit.

Key Points

  • To assess how different resin cements, silane surface treatment, and 3D-printed substrate materials influence shear bond strength.
  • Applied four resin cements (three self-adhesive and one adhesive) to two 3D-printed restorative resins: ODS Permanent Resin and Graphy Permanent Resin.
  • Tested each substrate with and without silane application, measured shear bond strength, and analyzed surface morphology using scanning electron microscopy.
  • Classified failure modes into adhesive, cohesive, and mixed categories across all test groups.
  • Resin cement type significantly affected shear bond strength, with Clearfil SA exhibiting the lowest values while the remaining cements produced higher, comparable bond strengths.
  • Silane treatment and 3D-printed substrate type demonstrated no statistically significant effects on shear bond strength.
  • Scanning electron microscopy showed smoother surfaces in ODS Permanent Resin than Graphy Permanent Resin, corresponding to predominantly cohesive failures in ODS Permanent Resin versus more adhesive and mixed failures in Graphy Permanent Resin.
