简要总结
Disimpaction of Mandibular thirdmolar is a common minor oral surgical procedure which can be problematic with asignificant incidence of iatrogenic complications. Causative factors forcomplications associated with disimpaction have been reported to be age,infection history, operator skills and type of impaction. The anatomic relationof third molar roots to the inferior alveolar nerve forms the most importantfactor amongst all the other factors.
Traditionally periapical radiographs have beenused diagnosis of the impacted teeth. The advantages of these radiographictechnique are reduction in radiation and less magnification but one of themajor disadvantages of periapical radiographs is Mandibular canal cannot beclearly identified. Also, the angulation of the radiograph can affect theposition of the canal which can lead to misinterpretation of the apices of theimpacted tooth in relation to Mandibular canal. However digital imaging, too,could not considerably help reduce the complications.
With the advent of this newtechnology and imaging system it is now possible to have an accurate knowledgeabout the regional anatomy. Preoperative CBCT and DICOM image files can help toobtain exact diagnosis, determine the proximity of Inferior Alveolar Nerve,amount of bone covering the third molar. The CBCT based DICOM images can beimported for virtual surgical planning where the area of interest can besegmented and the relations to anatomical structures can be viewed andaccordingly the treatment plan for surgical extraction of impacted third molarcan be planned with a guided model.
Thus the rationale of this study is to come up with methods to reduce the incidence of complications related to surgical extraction of impacted Mandibular third molar with virtually planned surgical guide for precise osteotomy and odontectomy for minimally invasive procedure and enhanced clinical outcomes.
