Which fixed orthodontic treatment is elected for deep bite treatment?

• A. Use of reverse arch
• B. Tongue shield
• C. Intermaxillary elastics
• D. High bracket fixation on frontal teeth

Answer: (A)

Deep bite correction with fixed appliances relies on changing vertical tooth positions to reduce the excessive overlap. The most direct way to open a deep bite is to intrude the anterior teeth while allowing the posterior teeth to remain or erupt slightly. A reverse arch wire is designed exactly for this: its curvature is opposite the normal curve of Spee, creating intrusive moments on the front teeth and facilitating bite opening. This targeted intrusion of the anterior segment is why the reverse-arch approach is the best choice for deep bite treatment. Tongue shields address habit or tongue-thrust issues rather than producing controlled anterior intrusion. Intermaxillary elastics can adjust tooth positions but don’t reliably provide the controlled intrusion of the anterior teeth needed for a deep bite, and their effects can be unpredictable. High bracket fixation on frontal teeth by itself doesn’t generate the necessary intrusive forces to correct a deep bite.
