    Study Notes

    Impacted Tooth Radiography and Surgical Planning

    • Preoperative, intraoperative, and postoperative divisions of treatment planning
    • Preoperative radiographs: periapical, occlusal, lateral, and panoramic for detailed tooth and bone assessment
    • Frank shift technique for mandibular canal localization in relation to lower third molars
    • Clark shift method for determining the position of impacted cuspids
    • Classification of impacted mandibular third molars based on space and depth in bone
    • Winter's classification of impacted mandibular third molars based on their orientation
    • Classification of impacted maxillary third molars based on their depth and position in relation to the sinus
    • Classification of impacted maxillary canines based on their location in the maxilla
    • Factors complicating the removal of impacted teeth: abnormal root curvature, hypercementosis, proximity to mandibular canal, extreme bone density, and ankylosis
    • Ankylosis: fusion of tooth with alveolar bone due to trauma or inflammation
    • Difficult access to operative field due to anatomical constraints like small orbicularis oris, limited mouth opening (trismus), and large uncontrollable tongue.
