FUSION DENTAL IMPLANTS offers two solutions for angled screw channel crowns at 30° capacity. Patented in the U.S., the Universal Solution by IBO is one universal titanium base for two screw options: standard screw-retained crowns (implant manufacturer drivers) and angled screw channel crowns with the Angle Correct (AC) screw and universal driver. The Sure Solution Ti-base kit from BHS30 features a connection between the external ball head screw and driver that is preferred for stable, long-term restorations due to high torque resistance without screw head damage. It also comes with a plastic angled cylinder used for waxing and ceramic pressing.

The primary objective of this study was to design the optimal geometry of a novel screwdriver; create the grooves on a ball head screw; and demonstrate its resistance to a torque of up to 40 Ncm at an angulation of 0, 15 and 30 degrees by using nonlinear finite element analysis. A secondary objective was to create a fool-proof and easily recognizable system. The grooved ball head screw and geometry of the screwdriver, functioning from an angulation of 0° to 30°, was generated using Pro-ENGINEER Wildfire 5.0 software. Static structural analyses between bodies in contact were performed at different angles of 0°, 15° and 30° at a torque of 20 Ncm and 40 Ncm, using nonlinear finite element simulation by means of ANSYS 12.0. The maximum stress supported by the ball head screw and screwdriver was similar at 20 Ncm and 40 Ncm. Although greater deformations were found at 40 Ncm, these were small and might not affect the performance of the system. Besides, the rupture torque value for the M2 connection was 55 Ncm for 0° and 30°, and 47.5 Ncm for 15°. Numerical simulation showed that the ball head system design can achieve the mechanical strength requirements expected for screws used in implant-supported restorations at an angulation of up to 30°. Finite element analysis showed this novel ball head screw and screwdriver system to be a good solution for angled screw channels in implant-supported prostheses.
