This high-yield revision note on Exodontia: Forceps, Elevators, Principles & Complications covers everything examiners typically test under Oral Surgery — structured as quick-reference tables, clinical correlations, mnemonics and previous-year-style high-yield points. It's built for last-mile revision before NEET MDS, INI-CET MDS and INBDE, so you can scan it in minutes instead of re-reading a whole textbook chapter.
| Concept | Detail |
|---|---|
| Extraction forceps | Work via a combination of wedge, lever, and wheel-and-axle mechanical principles; beak design is adapted to the cervical anatomy of the tooth being extracted |
| Elevators | Primarily work via lever (Class I), wedge, and wheel-and-axle principles - e.g. straight elevator, Cryer's (triangular, for root fragments), Winter's (cross-bar), Potts elevators |
| Principal extraction movements | Apical pressure, buccolingual/labiolingual expansion, controlled rotation (single-rooted teeth only), and tension for final delivery |
| Common complications | Root fracture (MOST COMMON complication), oro-antral communication (OAC, especially maxillary molars), maxillary tuberosity fracture, damage to adjacent teeth, mandible fracture (rare, mainly in atrophic mandibles), TMJ injury, aspiration/ingestion of tooth fragments |
| OAC management | Small communications (<2mm) may heal spontaneously; larger defects typically require surgical closure with a buccal advancement flap (Rehrmann flap) |
