We have several types of crown designs, but here, we shall limit ourselves to select few, most common ones. For detailed study, one can consult a standard text book. The main types of the crown preparations are:

  1. Full cast metal crown
  2. Porcelain fused to metal crown
  3. All ceramic crown
  4. Crown preparations specially designed for specific material

Your main focus should be on the type of finish lines and the thickness of the crown/abutment preparation. For details of various finish lines you can see HERE.

For amount of crown cutting and the optimum needed width of the finish line, you can go HERE.
