Implant Crown has an extra layer of challenge because of metal shade stump. Using translucent materal may match better with adjacent teeth yet have to risk gray underlying shade. Using strong opaque zirconia may mask the metal shade better yet risk not matching the adjacent teeth.
 
For our custom abutments, we purchase the premills that had already milled connection parts and OEM screws. We only mill above the connection such as customized profile emergence, margin height and parts above the margins.  We use NT Trade, Dess and Arum Premills so that you'll never be concerned about the fit at the connection.
 
Disclaimer: We only guarantee that the milling will be completed according to the design. Settings in the cement gaps and path of insertion could affect the fit of the crown. Any remakes for these reasons will be charged in full.
