pared teeth or abutments.

– The minimum wall thickness of 1.5 mm occlusal and 0.8 mm circular must be observed at all times.
– The connector dimensions for anterior bridges with up to two pontics must be at least 12 mm
2 .
– The connector dimensions for posterior bridges with one pontic must be at least 12 mm 2 and with up
to two pontics at least 16 mm 2 .
Grinding and set-up
