Key Points

  • This study aims to evaluate the effect of surface modifications on bond strength between 3D printed acrylic denture bases and teeth.
  • Conducted an in-vitro assessment of bond strength under varying surface conditions.
  • Applied different surface modifications to the ridge lap of 3D-printed acrylic teeth and resin.
  • Compared modified surfaces with unmodified controls to determine bond strength variation.
  • Surface modifications did not enhance bond strength compared to unmodified surfaces.
  • Some modifications potentially reduced the bond strength, indicating a need for alternative approaches.

Abstract

These findings suggest that surface modifications to the ridge lap of 3D-printed acrylic teeth and resin may not improve and could potentially reduce bond strength when compared to unmodified surfaces. The study highlights the importance of exploring alternative methods, particularly chemical surface treatments, to enhance the adhesion between 3D-printed denture bases and teeth.
