| 1 | Confirm the Roth prescription | Torque, angulation, and in-out values | Request a complete prescription chart for every tooth position. Roth values are not universally identical across manufacturers, so torque and angulation must be verified against the supplier's technical drawing. | Do not approve a product based only on the word “Roth.” Compare the prescription chart with the orthodontist's treatment system and intended finishing requirements. |
| 2 | Select the correct slot size | Archwire slot dimension | Common options are 0.018 × 0.025 inch and 0.022 × 0.028 inch. The selected slot should match the practice's archwire inventory and preferred finishing mechanics. | Require slot-size identification on the product label or packing list. Mixing slot systems can affect wire engagement, torque expression, and inventory control. |
| 3 | Evaluate bracket design and identification | Twin-wing form, hook configuration, and tooth marking | Specify standard or mini twin brackets, required hooks, permanent or laser-etched tooth identification, and right/left or upper/lower orientation markings. | Check that markings remain readable after handling and that hook position supports the planned elastics, auxiliaries, and ligation technique. |
| 4 | Review material and surface quality | Bracket body, slot finish, and corrosion resistance | For stainless-steel brackets, request the stated material grade, manufacturing method, surface-finish description, and evidence of resistance to corrosion and discoloration under normal clinical use. | Inspect sample brackets for burrs, sharp edges, rough slot walls, incomplete hooks, or visible surface defects that could interfere with wire movement or patient comfort. |
| 5 | Verify the bonding base | Mesh pattern, base contour, and bond reliability | Request base dimensions, mesh or retention pattern, tooth-specific contour, and documented bond-strength testing performed using a defined adhesive and test method. | A bracket should provide adequate retention without excessive adhesive flash. Test samples on representative tooth surfaces before committing to a large purchase. |
| 6 | Assess dimensional accuracy and consistency | Slot accuracy, bracket height, and batch variation | Ask for dimensional tolerances, inspection records, sample measurements, and lot or batch traceability. Critical dimensions should be checked with calibrated equipment. | Inconsistent slot geometry or bracket height may alter wire play, bracket positioning, and finishing control. Compare pre-production samples with delivered goods. |
| 7 | Check documentation and supply controls | Quality system, packaging, labeling, and traceability | Obtain product specifications, inspection criteria, lot numbers, manufacturing date, shelf-life information where applicable, packaging details, and instructions for use. | Confirm that packaging protects the brackets from deformation and contamination. Follow the applicable local medical-device requirements and the supplier's instructions for use, including any sterilization guidance. |
