Advantages of Ceramic Overlay Restorations
Ceramic overlay restorations offer a valuable alternative to traditional crowns, providing partial or full occlusal coverage with an indirect approach. Dr. Ferrars emphasizes the importance of following a specific protocol tailored to adhesive concepts and new materials, highlighting the precision required for optimal results. He discusses the limited need for inlay restorations due to advancements in direct restorations, underlining the critical role of adhesive dentistry in modern dental practices.
Testing Occlusion in Adhesive Rehabilitations
In adhesive rehabilitations involving occlusal changes, conducting a test drive is crucial for assessing functional outcomes. Dr. Ferrars describes creating mock-ups using analog or digital models to simulate the final restoration, ensuring proper fit and function. By replicating the new occlusal scheme in a removable tray, dentists can evaluate functionality and patient comfort before final cementation, emphasizing the importance of biomechanical behavior and long-term stability.
Provisionalization and Occlusal Adjustments
Provisionalizing entire sextants with high-viscosity flowable materials allows for stability during occlusal adjustments and adaptation to changes. Dr. Ferrars recommends using materials like HF flowable or high-viscosity composites for provisional restorations, ensuring durability and wear resistance. When transferring occlusal changes to the final restoration, referencing key points and employing digital scans aid in replicating the adjusted occlusal scheme accurately for optimal treatment outcomes.
