- lingual and proximal axial reduction of the tooth structure,
- distinct proximal grooves
- lingual groove
- an incisal offset
- Cast post and core with interlocking prefabricated post on molar
- No lingual reduction of canine
- Four parallel groves on premolar and molar
The whole preparation is made as parallel as possible using by AcuHand System to electronically control position of cutting instrument.

The abutment teeth have considerably different axial inclination.
Making a conventional crown on a molar would require a significant removal of sound tooth
structure on facial side to fit the bridge.
