Usage methods (Surgical techniques)

OSTEOTRANS System may basically be used in the same way as metallic osteosynthesis device, but, as it's mechanical strength is inferior to metallic devices, caution should be exercised to avoid receiving unreasonable force. It is advisable to use the special Takiron surgical instruments (drill bit, tap, screwdriver, and countersink) which matches to the type and size of the product. Screws are not designed for self-tapping, so after drilling and cleaning/suctioning, tapping is required before insertion. Insert the screw only after thoroughly cleaning out the hole. To avoid screw head damage, insert the screw with the screwdriver, with downward axial-loading applied.
