Posterior Partial Coverage Restorations: Decision Making and Preparation Designs

This lecture explores the modern decision-making process for posterior partial coverage restorations, emphasizing conservative, evidence-based preparation designs. Through a progression from traditional gold restorations to contemporary adhesive techniques, participants will gain an understanding of the biological, mechanical, and esthetic principles that guide clinical choices. The session will highlight modern restorative philosophies such as Immediate Dentin Sealing (IDS), Deep Margin Elevation (DME), and Cavity Design Optimization (CDO), providing a comprehensive framework for selecting the appropriate restorative approach in daily practice.

Upon completion of this course, participants should be able to:

1.    Identify clinical scenarios that indicate direct versus indirect posterior restorations.
2.    Apply decision-making principles to determine the need for total versus selective cuspal coverage.
3.    Understand the role of Immediate Dentin Sealing, Deep Margin Elevation, and Controlled Adhesive Cementation in improving long-term outcomes.
4.    Evaluate preparation geometry and margin design for enhanced function, esthetics, and longevity.
