• When prepping a tooth for an anterior Zirconia crown, you will need to ensure sufficient room for the wall thickness to have a minimum of 0.3 mm and ideally between 1.0 mm and 1.5 mm, or 1.8 to 2.0 mm incisal reduction.
• There should be a visible and continuous circumferential chamfer with at least a 0.5 mm reduction at the gingival margin.
• The horizontal and vertical preparation of the tooth should have an angle of approximately 5°, and a bevel is not advisable.
• All the incisal edges should be rounded, and the lingual aspect of the anterior should be reduced with a football diamond to create a concave lingual.
