What type of abutment screws does DESS manufacturer?

DESS makes over 50 different screws for the various implant systems. Within the DESS 2015 Catalog there is a "Screw Selection Guide" which has detailed measurements of all the screws DESS manufacturers including - single unit, multiunit/bridge, diamond/carbon coated (DLC), angulated channel screws.

All of the screws are made according to the same screw sockets of the manufacturers, for example the Nobel® unigrip/star driver will be used on all our compatible Nobel screws, torx driver will be used on all compatible Straumann® screws, etc.

DESS Screws are tested to 150% of the nominal screw torque...how is that possible?

Not all Ti6Ai4V ELI titanium alloys are the same. We work with one European vendor who provides us with ASTM F136 Standard approved titanium. The ASTM F136 requirement is 860MPa for the Ultimate Tensile Strength (Rm). For our screws we utilize a ASTM F136 Standard approved titanium with over 1100 -1200MPa. The screws are stress tested to 150% of the nominal screw torque. For example the DESS compatible screw for Nobel can be torqued to 52.5ncm versus 35ncm.

What screws does DESS make with the diamond/carbon coating (similar to Nobel®) ?

The DLC coating is Chromium Carbonitride - CrCN which provides a low friction surface, improving the preload of the screw and provide better hold. The Chromium Carbonitride coating is not toxic and has excellent mechanical, tribological and biological properties. It is often used in blood contacting implants such as stents and heart valves and to reduce wear in load bearing joints.

The screws compatible with Nobel Replace, Nobel Active®, Branemark®, and Multiunit are available with the DLC coating.
