50 I I industry report _ shaping canals Afterwards, we remove any coronal interference using the 35.08 EndoWave file (Morita). It is a very short and strong instrument designed to perform this function quickly and safely. After reducing the risk of instrument fracture, we finally introduce a stainless-steelinstrumentuptotheapicalterminus to confirm the exact working length. We then per- form the canal shaping in a few seconds by means of a 20.06 or 25.06 EndoWave file. What best describes our Hybrid Concept tech- nique? Safe (the instrument fracture risk is mini- mum), quick (only three steps), low risk of anatomic deformation (no use of stainless-steel instruments, especiallyinthedelicatestepofprobing),predictable (because it is performed according to electronically guided endodontics). The less skilled the operator, the more effective this technique is. It has become evensaferwiththenewmotorDentaPortZXSetOTR (Optimum Torque Reverse; Morita). It makes it pos- sible to shape canals with rotating motion and re- ciprocating motion. Instruments rotate within the canal,butwhenthepresenttorquelevelisexceeded, the reciprocating motion will start (90 degrees/ Figs. 5a & b_Average difficulty case: endodontic treatment of a mandibu- lar left first molar (Dr Fabio Rovai).
