Mini-invasive orthodontic -surgical treatment of a granuloma localized inside the mandibular canal

Proximity of the third mandibular molar to the mandibular canal generates risks of lesion to the mandibular nerve in case of surgical extraction procedures. The possibility of increasing the distance between the tooth and the nerve by means of orthodontic extrusion can be a valid strategic procedure to reduce the surgical risks. The authors applied a security protocol in a case of granuloma positioned in the mandibular canal in order to extrude and then extract tooth 4.8 with the aid of 2 TADs (Temporary Anchorage Devices) and a lever arm made of Titanium-Molybdenum-Alloy (beta-titanium).
