Platform switching. The platform switching connection occurs when the diameter of the prosthetic parts, emerging from the implant, is smaller than that of the implant platform. About 1 mm of the neck, 2.5 mm in version S1T and S1Tn (Unico), which protects more from bacterial attacks in the machined version. Cutting coronal threads for a better force discharge on cortical bone to provide excellent stability even in few millimetres. 55° triple thread over the entire body implant with a pitch of 1,8 mm (0,6 mm/thread); each turn allows going down of 1,8mm, speeding up the insertion phase. 3 apical aggressive cuts provide better primary stability while centring the implant and the possibility to change direction during its insertion. Apex aggressive but rounded to protect Schneider’s membrane.
