Statistical analysis revealed significant differences among the test groups for position (G0 P<.001; G1 P<.05; G2 P<.001; G3 P<.001) and direction (G0 P<.005; G1 P<.001; G2 P<.001; G3 P<.001). Without soft tissue interference, the accuracy of certain digital scanning systems was comparable with that of the conventional impression technique. The amount of flexible soft tissue interference affected the accuracy of the digital scans.

The amount of flexible soft tissue interference affected the accuracy of the digital scans. The angled screw channel concept has become popular. However, research is lacking as to how reverse torque values of nonaxially tightened implant crowns compare with axially tightened cement-retained crowns restored on angle-correcting abutments when subjected to long-term cyclic loading. The purpose of this invitro study was to evaluate the ability of different 25-degree angled screw channel hexalobular systems to apply the target torque value on their screws, the effect of cyclic loading on their reverse torque values, and their survival compared with crowns cemented on conventional 0-degree screw channel abutments. A total of 28 implants were divided into 4 groups. Twenty-one angled screw channel crowns were fabricated at a 25-degree angle correction by using angled titanium (Ti) bases by 3 manufacturers DY (Dynamic Tibase), DE (AngleBase), and ASC (Angulated Screw Channel) (n=7). The fourth group, UB (Universal Base, Control), had cement-retained crowns with 25-degree custom-milled, angled zirconia -to-failure survival of all groups was similar. Fractures at the zirconia to titanium base connection were seen with ASC crowns. The hexalobular system of DY delivered comparable in
