*The largest wire in dimension compatible with the square holes of OBS 2.4 is 0.019”x0.025”.
**TADs made of Ti alloy have a lower failure rate compared to SS when placed in thin cortical bone. These results are consistent with a biocompatibility-related tendency for less bone resorption at the bone screw interface. Reference: Failure rates for SS and ti-alloy incised anchorage screws: single-center, double blind, randomized clinical trial (J Digital Orthod 2018;52:70-79).
***The overall success rate of 93.7% indicates that both SS and TiA are clinically acceptable for IZC BSs. Reference: Failure rates for stainless steel versus titanium alloy infrazygomatic crest bone screws: A single-center, randomized double-blind clinical trial (Angle Orthod 2019:89:40–46).
