What is PFM Crown Preparation Techniques about?
The metal ceramic crown preparation involves making depth grooves, reducing the incisal edge, labial surface, and axial surfaces of the tooth. The labial surface is reduced to create a 1mm shoulder at the cervical margin. The axial and lingual surfaces are tapered at 6 degrees to provide at least 1mm of clearance for the metal substructure. The preparation is then finished smoothly to aid in impression making and casting.
