Module 2: PRINCIPLES OF ADHESION

This module provides an in-depth understanding of the principles of adhesion and cementation for various aesthetic dental materials. Participants will explore the chemical and mechanical bonding mechanisms between aesthetic materials and tooth structure, as well as strategies to optimize long-term clinical outcomes. The course will cover key aspects of adhesive systems, preparation protocols, and the selection of appropriate cementation techniques for different restorative materials, including ceramics, composites, and hybrid materials. Emphasis will be placed on evidence-based approaches to achieve predictable, durable, and aesthetically pleasing restorations.
