Fixed partial denture-Part 1

Delve into the world of fixed prosthodontics with a comprehensive exploration of full veneer crowns. This course provides a strong foundation, blending clinical understanding with essential theoretical knowledge.

We begin by understanding the fundamental role of dental crowns in restorative dentistry – when they are necessary, the different types available, and their respective indications and contraindications. You'll gain a clear understanding of crown preparation, including its definition and crucial requirements.

A core focus is on the 5 principles of crown preparation:

• Preservation of tooth structure: Minimizing tooth reduction for optimal longevity.
• Resistance and retention form: Designing crowns that withstand occlusal forces and maintain a secure fit.
• Structural durability: Ensuring the crown can withstand long-term use.
• Marginal integrity: Achieving a tight seal at the crown-tooth interface to prevent leakage.
• Preservation of periodontium: Protecting the surrounding tissues during preparation.

Explore the various types of finish lines used during crown preparation, analyzing their advantages, disadvantages, indications, and contraindications. Learn about the diverse burs employed in crown preparation and their specific applications.

The course then dives into the world of full veneer crowns, examining the different types currently used in dentistry. We'll cover their pros and cons, ideal scenarios, and situations where they are not suitable.

Understand the necessary armamentarium required for successful crown preparation. Detailed, step-by-step procedures are provided for preparing:

• All-metal full veneer crowns
• Porcelain-fused-to-metal (PFM) full veneer crowns for anterior teeth
• PFM full veneer crowns for posterior teeth
• All-ceramic full veneer crowns for anterior teeth
• All-ceramic full veneer crowns for posterior teeth

Finally, each crown preparation procedure concludes with a detailed summary including diagrams illustrating the finish lines and the precise reduction required on the labial, lingual, occlusal, and incisal surfaces. This ensures a thorough understanding of the entire process.
