An upper right premolar was restored with huge composite filling, and limited tooth preparation was too risky. We chose to cover it with full crown. A molar, on the other hand was a good candidate for minimal tooth reduction. photo
Preparation

photo
  1. lingual and proximal axial reduction of the tooth structure
  2. distinct proximal grooves
  3. an occlusal offset
  4. No casp reduction of molar
  5. Four parallel groves on premolar
The whole preparation is made as parallel as possible using by AcuHand System to electronically control position of cutting instrument.
