In the margin
The line where a veneer or crown meets the tooth is where plaque hides and where a poor fit shows as a dark line. A precise margin, measured in fractions of a millimetre, is what keeps the restoration and the tooth healthy.
In the bite
A restoration that is fractionally high concentrates biting force and fractures. Every fitting ends with the bite checked and balanced.
In the design
Symmetry to the face, proportion between teeth, the exact amount of tooth showing at rest. These are decided on screen and verified in the mouth before the laboratory begins. Precision is planned, not hoped for.
