It particularly notes the rising complexity of extractions in older patients due to demographic shifts.
Key Components
Definition & Historical Context
Exodontia is defined as the painless removal of a whole tooth or root, minimizing trauma to surrounding tissues to ensure uneventful healing and avoid postoperative prosthetic issues.
The chapter also traces its evolution from early rudimentary methods—often performed by barber‐surgeons—to modern refined techniques, referencing classical figures such as Sushruta and Geoffrey Howe.
Surgical Anatomy & Patient Management
In‑depth discussion of maxillary vs. mandibular extraction challenges, including bone density, sinus proximity, and nerve supply, underlines the importance of anatomical understanding.
Equally emphasized is patient trust and communication, tools for anxiety management, and tailored pharmacological planning for safe procedures.
Indications, Contraindications & Preoperative Assessment
Clear indications include non‑restorable teeth, periodontal disease, orthodontic or prosthodontic planning, and trauma.
Contraindications span systemic conditions (e.g., uncontrolled diabetes, bleeding disorders) and local factors such as active infection or malignancy.
Preoperative assessment includes detailed medical and dental history, clinical and radiographic examination, access evaluation, and mobility assessment.
Extraction Techniques
✔ Intra‑alveolar (closed) extraction
Standard approach for intact erupted teeth. Relies on proper luxation motions and controlled force to expand the socket before removal.
✔ Trans‑alveolar (open/surgical) extraction
Applied when crown structure is inadequate, tooth is impacted, or force requirements are too great. Involves flap elevation, bone removal, tooth sectioning, and use of elevators or physics forceps.
Technical Principles & Mechanical Mechanics
Mechanical principles include socket expansion via lateral motion, lever and fulcrum mechanics, and wedge insertion into the periodontal ligament space to facilitate elevation of the tooth.
Extraction of multirooted teeth may require sectioning into multiple single‑root fragments (odontectomy), especially in molars.
Postoperative Care & Healing
The progression of socket healing—from clot formation through epithelialization and bone remodeling—is explained with emphasis on preventing complications like dry socket.
Protocols include irrigation, smoothening bony edges, suturing, and clear postoperative instructions.
Complications & Risk Management
Comprehensive coverage of possible adverse outcomes—such as hemorrhage, oroantral communication, bone fractures, root displacement, temporomandibular injury, and infection—is paired with management strategies including local hemostatics, suturing, imaging, and timely surgical intervention.
Technological Innovations
The chapter reviews recent advances:
✔ Powered periotomes, enabling controlled severing of periodontal ligament fibers with minimal trauma
✔ Physics forceps, applying lever mechanics to minimize tissue damage and expedite extraction
✔ Use of implant drills for pre‑extraction root thinning, Er:YAG lasers, and piezo surgery techniques that allow precise bone cutting with reduced soft‑tissue risk.
* This chapter serves as an essential resource for clinicians seeking to refine their extraction technique, expand their anatomical and procedural knowledge, and stay abreast of modern surgical tools.
