What is the term for an appliance that is cemented or bonded to a tooth?

• A. Fixed Appliance
• B. Extrusion
• C. Intrusion
• D. Proper Occlusion

Answer: (A)

The concept here is an orthodontic device that is anchored directly to teeth. When an appliance is cemented or bonded to a tooth, it becomes a fixed appliance. Brackets and bands connected by a wire are classic examples—once attached with dental cement, they stay in place and can only be adjusted or removed by the clinician. This is different from removable appliances, which patients can take out themselves. Extrusion and intrusion describe movements of teeth (pushing a tooth outward toward the cheek or lip, or pushing it inward toward the bone), not the device itself. Proper occlusion refers to how the upper and lower teeth come together, i.e., the bite, which again is not an appliance. So the term that best fits the description is fixed appliance.
