Tri-Nex  3.5 mm X 8 mm



TRI-NEX dental implants feature a hex drive the tri-lobe connection which is used for the implant insertion. Driving on the hex protects the integrity of the lobes for prosthetic fit. at time of restoration. The coronal walls of the 3.5 mm and 4.3 mm diameter TRI-NEX are reinforced to further strengthen the implant. The reinforcement of the coronal wall fashions a beveled edge that creates forced “platform switching”.


Increasing demand for PRIMARY STABILITY, means that implants are being placed with ever increasing insertion torues. The Southern external thread has proven suitability for high insertion torque without causing bone necrosis. Hence the need for an insertion drive mechanism that:

  1. Give precise feel and control / rigidity
  2. Can transmit insertion torques up to 100Ncm
  3. Will not disstort or damage the prosthetic interface
  4. Will not weaken or reduce fatigue resistance of the implant

These requirements are answered by the hex drive of the TRI-NEX implant.
