With regard to the external implants with a hexagon connection, in addition to retaining the device in the vertical gap, the horizontal gap between the hexagonal connection of the abutment and implant must be reduced as much as possible, in order to minimize rotation between the devices.
This phenomenon, impossible to prevent with this type of connection, places the prosthetic stability at risk and, above all, leads to premature loosening of the prosthetic screws.
A number of scientific papers, written during the 1990s by Paul Binon in the United States, consider a connection which does not exceed 4° of rotation to be acceptable. Few international companies are able to achieve these results and Dental Tech is one of these. By working to tolerances reduced to a minimum and maintaining tight control over all devices, Dental Tech is able to obtain a minimum and maximum rotation from 0.18° to 0.93° between the parts in question, guaranteeing excellent stability of the connection and prosthetic screws which hold in place.
