Endo treated teeth P2 Flashcards
What is the main advantage of adhesive restorations?
Macroretentive elements are no longer mandatory as long as enough surface is available, thanks to dentin adhesives.
How did adhesion change the restoration of endodontically treated teeth?
Adhesion made it possible to create restorations without relying on macromechanical retention, allowing for better aesthetics and function.
Who first described the endocrown and when?
Bindle and Mörmann first described the endocrown in 1999.
What is an endocrown?
An endocrown is a total porcelain crown that is anchored to the internal portion of the pulp chamber and cavity margins of endodontically treated teeth.
How does the monoblock technique work in endocrowns?
The monoblock technique uses macromechanical retention from the pulpal walls and micromechanical retention through adhesive cementation.
How is intracoronal height reduced during endocrown preparation?
It is reduced to 2.0 mm, measured from the internal cavity margin to the floor of the pulp chamber.
What is the correct alignment for axial walls in endocrown preparation?
Axial walls should have an internal taper of 8-10 degrees, using a tapered diamond bur.
How are CAD/CAM ceramic endocrowns fabricated?
They are fabricated using systems like CEREC, with materials such as feldspathic ceramic, lithium disilicate, or resin nanoceramic blocks.
What materials are commonly used for CAD/CAM endocrowns?
Feldspathic ceramic, lithium-disilicate blocks, and resin nanoceramic blocks are commonly used for endocrowns.
What is the purpose of smoothing internal line angles in endocrown preparation?
Smoothing internal line angles helps reduce stress concentration and improves the fit of the endocrown.
