[QUOTE="keithw@vodamail.co.za, post: 144486, member: 4378"] Mcfly, I don't use Lt ingots to block out discoloration. A grey prep will shine through (grey out) a pressed LT coping or a full contour anterior. If preps are not discoloured then I use LT ingots no problem, if you got dark stumps, you gotta block them out by pressing HO copings. On posteriors, i don't worry too much, press lots of fc crowns in LT. Dentists rarely give me a stump shade unless the stump very dark and they know it will need masking. Mostly I use the neck shade given on lab slip as the stump shade. Most posteriors have wall thickness over 1.5 mm and when pressed in LT ,stump shades don't cause too many issues, have not had remakes etc due to shade issues. [/QUOTE]
