Orthodontic extraction: the extraction of the third molars in close proximity to the mandibular canal by an orthodontic-surgical approach

An orthodontic-surgical approach to performing riskles extractions of those third molars with contiguity between the roots and the mandibular canal. Different phases: first the surgical risks have to be assessed. A first topographic diagnosis is made using a panoramic radiograph and then, if there is a suspected contact between root and mandibular canal, a CT scan is done. When the proximity is confirmed, "the orthodontic extraction procedure" will start with the creation of an orthodontic anchorage. This phase is followed by a surgical exposure of the third molar crown in order to bond a bracket to the occlusal surface. A stainless steel sectional wire is anchored from the first molar to the third molar to produce the extrusive forces. After a positive clinical assessment of the extrusion level, a new radiological check is requested to evaluate the tooth movement. When trhe tooth is out of the mandibular canal, the surgeon can perform a safe and easy third molar extraction.
