The TPA screws allows us to screw the prosthesis once the angle of the trans occlusal canal of the restoration has been corrected, in order to improve the functionality and aesthetics.
The screws are used together with an screwdriver that allows you to screw up to an angle of 28 °. The 25 mm long screwdriver has a controlled breaking point that ensures that, in the case of an excessive tightening torque, that could damage the screw connection, it fractures in an area that allows its comfortable extraction, avoiding that the TPA screw is left inaccessable.
All TPA screws maintain the lengths and seats regarding the original counterparts, and can be used with any implant CAD-CAM library compatible with the system being worked on. Not needing any additional programme or library.
The TiN coating applied to the TPA screw reduces the risk of loosening, avoids deformation of the sides of the thread, increases pre-load and resistance to fracture due to fatigue and in addition reduces bacterial adhesion.
