The abutment and screw connection involves creating highly accurate geometries and extremely precision machining. We utilize the same technology as the major implant companies - including the same design programs, same Swiss & Japanese machines, and the same metrology measurement instruments. DESS even manufactures for some of the implant companies. Regarding patents - most connection methods are not patented.
In order to manufacture a compatible component, the original implants must be utilized (typically a minimum of 20 of each platform). We measure original components to get a CAD image, produce prototypes, and test – both mechanically and with sophisticated measuring instruments (metrology systems), and based on these thorough evaluations we set our own tolerances to assure fit and compatibility all the time. Extensive stress testing on the components is performed.
