Surface Preparation for Mechanical Bonding

Methods for Producing Surface Roughness

  • Grinding and Etching: The common methods for creating surface roughness to enhance mechanical bonding include grinding or etching the surface.
    • Grinding: This method produces gross mechanical roughness but leaves a smear layer of hydroxyapatite crystals and denatured collagen approximately 1 to 3 µm thick.
    • Etching: Etching can remove the smear layer and create a more favorable surface for bonding.

Importance of Surface Preparation

  • Proper surface preparation is critical for achieving effective mechanical bonding between dental materials, ensuring the longevity and success of restorations.
