Shades and Contour of a Single Crown
- Fig.1,2 show shade selection for #9 implant case for Mrs. WY Li.
Shade A3 is to be used for gingival portion, whereas A2 for incisal portion
- For implant cases, porcelain could be a little more than necessary
buccally to cover the Titanium, whereas for natural teeth, overcontour is
not acceptable
- For anterior cases (including premolars), anterior tray impression
is taken, so that we can use the tooth on the other side as reference.
If the machine produces an overcontoured crown, please fix it by hand
- Recently, crown margin is shy. From now on, make margin a little
bit longer, ~ .5 mm buccal of the anteriors, ~ .025 mm posteriors
