For orthodontic lab work, what are two common components the lab fabricates for fixed appliances?

• A. Wires and archwires.
• B. Brackets and bonding trays.
• C. Aligners.
• D. Implants.

Answer: (B)

In fixed orthodontic appliances, the lab’s typical fabrication focus is on brackets and bonding trays. Brackets are the small attachments that bond directly to each tooth and guide the archwire to produce tooth movement; they come in various prescriptions (torque, angulation, width) and materials, and the lab often fabricates them to match the clinician’s treatment plan. Bonding trays, or indirect-bonding trays, are custom-made to hold adhesive and brackets in precise positions so brackets can be transferred from the model to the patient’s teeth with accurate alignment and spacing. This pairing—brackets for attachment and bonding trays for precise placement—is a standard lab function for fixed appliances. Wires and archwires are typically supplied or purchased as standard components rather than custom-fabricated by the lab. Aligners are used for removable treatments and are produced through a different workflow, not part of fixed appliances. Implants are separate from orthodontic fixed appliances and aren’t what a dental lab routinely fabricates for that category.
