Wisdom Tooth Extraction Guidelines

Diagnostic Imaging

Orthopantomography (panoramic X-ray) is recommended as the first diagnostic examination for suspected dental impaction, providing initial information on tooth position, relationship with adjacent structures, and presence of associated lesions, as suggested by the American Dental Association and the American College of Radiology 1
Panoramic X-rays are useful for assessing the relationship between third molars and the mandibular canal, but CBCT is necessary when panoramic imaging suggests contact between these structures or with the maxillary sinus floor, as recommended by the American Dental Association 1
CBCT is superior to 2D imaging techniques in assessing relationships between impacted teeth and critical anatomical structures, such as the inferior alveolar nerve, according to the American College of Radiology 1
The use of targeted CBCT imaging following the ALARA principle (As Low As Reasonably Achievable) for radiation exposure is recommended, as stated by the American College of Radiology 1

The inferior alveolar nerve, a branch of the mandibular division of the trigeminal nerve (fifth cranial nerve), runs through the mandibular canal and provides sensation to the lower teeth, lower lip, and chin, as described by the American Association of Oral and Maxillofacial Surgeons 1

CBCT contributes to optimal risk assessment and surgical planning by providing precise anatomical knowledge, allowing for modified surgical techniques, as recommended by the American Dental Association and the American Association of Oral and Maxillofacial Surgeons 1
The surgical approach should be based on tooth angulation, depth of impaction, and relationship to adjacent structures, as stated by the American College of Surgeons 1
Careful flap design and bone removal techniques are necessary to minimize risks, as recommended by the American Association of Oral and Maxillofacial Surgeons 1
CBCT is essential to assess the relationship between lower third molars and the mandibular canal, and between upper third molars and the maxillary sinus floor, to prevent nerve injury and other complications, as recommended by the American Association of Oral and Maxillofacial Surgeons and the American Dental Association 1
