Wisdom Tooth Extraction: Dentist Chair Position & Procedure

The dental chair is adjusted to a reclined (supine or semi-supine) position—not a specific angle—to give the operator optimal access, visibility, and ergonomics for wisdom tooth removal.

Procedure Overview

1. Anesthesia: Local (lidocaine/articaine ± epinephrine); sedation (nitrous, oral, IV) or GA for complex cases.
2. Access: Incision, flap elevation if impacted.
3. Bone Removal: Bur or piezosurgery for bony impaction.
4. Sectioning: Tooth divided (crown/roots) for easier removal.
5. Elevation/Extraction: Elevators, forceps.
6. Debridement & Closure: Irrigation, hemostasis, sutures (often resorbable).

Chair Position Nuances

• Maxillary: Patient supine, chair tilted back; operator at 9–10 o'clock.
• Mandibular: Slightly more upright; operator at 8–9 o'clock.
• Adjustments made for patient comfort (pregnancy, POTS, vertigo) and operator ergonomics.

The chair angle is a tool for access—not a determinant of the surgical technique.
