Adhesive vs Cohesive. What’s the difference and when to implement which?

Educational Objectives

After completing this webinar, participants will be able to:
• Understand adhesive and cohesive dentistry 
• Review preparation designs 
• Update on current bonding principles


Our goal as clinicians is to responsibly preserve biologic tissue whilst improving the longevity and the esthetics of our restorations. Basically, our job is to improve on nature without harming it. Adhesive dentistry means bonding. Cohesive means fitting like a lock and key. Adhesive dentistry is typically synonymous with minimally invasive dentistry. When adhesive dentistry is not possible, cohesive dentistry can be used, and sometimes adhesive and cohesive protocols overlap. Thus, a clinician should have an idea, even before a preparation is made, whether a cohesive or an adhesive systematic approach will be used. In this presentation we will mostly focus on the fundamental principles of adhesive dentistry. We will cover which preparation design to use and how, and which materials work best in various situations. We will compare the utmost current and recommended bonding techniques for lithium disilicate and zirconia posterior restorations. We will also revisit cohesive design principals for retention and resistance form in order to understand preparation principles and luting protocols.
