Discover the principles of crown preparation, finish lines, and the five crown types—metal, porcelain fused to metal, all resin, all ceramic, and pressed ceramic—and the situations and contraindications for use.
Define tooth preparation as the mechanical treatment to restore a tooth, per Tillman and Marzook, and address biological, mechanical, and aesthetic requirements for crown preparation.
Explore the five crown preparation principles: preservation of tooth structure, retention and resistance, structural durability, marginal integrity, and preservation of periodontium, with occlusal and axial reduction and path of insertion.
Explore the four finish lines for crown prep—chamfer, heavy chamfer, shoulder, and knife edge—along with indications, advantages, and limitations for metal and ceramic restorations.
Explore burs for crown preparation: short/long needle diamond burs for proximal reduction and flat/tapered/round-end diamond burs for occlusal and axial reduction, creating shoulder and chamfer lines, lingual concavity shaping.
Explore complete cast crowns and other crown types, outlining indications, contraindications, advantages, and detailed tooth preparation steps: occlusal reduction, axial reduction, bevels, and seating guidelines.
Explains porcelain fused to metal crowns, or metal ceramic full veneer crowns, a metal coping with a facial ceramic layer that combines strength and aesthetics, with cut-back design and indications.
Prepare the anterior porcelain fused to metal crown by indexing, groove alignment, and labial, incisal, lingual, and proximal reductions, including wing preparation and a shoulder finish line.
Learn posterior porcelain fused to metal crown preparation, including indexing, occlusal, facial, proximal, and lingual reductions, functional cusp bevel, and precise finishing to ensure proper ceramic coverage and margins.
Introduce all ceramic crowns for high aesthetic needs, noting molar contraindications for conservative restorations, and fracture risks such as margin chipping and half moon fractures from edge-to-edge occlusion.
Learn all ceramic crown preparation with labial, incisal, lingual, and proximal reductions using flat and tapered diamonds, depth-oriented grooves, and a radial shoulder finish line for esthetic, pulp-safe results.
Master posterior all-ceramic veneer crown preparation, including indexing with silicone putty, occlusal reduction to 2 mm, facial and lingual reduction of 1 mm, proximal reduction, bevel, and finishing with evaluation.
This course is about one of the important topics of fixed prosthodontics. It is important from both clinical and theoretical point of view.
