With the patient in the supine position on the operating table, the surgeon perform the extra and intra oral antisepsis with chlorhexidine 0.2% and anesthesia of the inferior alveolar, lingual, buccal, posterior superior alveolar and greater palatine nerves respecting the protocol described by Malamed, with lidocaine 2% and epinephrine 1:100,000, with a maximum volume of 9 ml. Initially, an incision was made at the alveolar crest along the mesial or distal aspect in the mandibular branch to reach the distolingual region of the second molar, followed by intrasulcular incision surrounding the second molar to the interdental area between the second and first molar. Afterwards, the surgeon will raise the mucoperiosteal flap, perform an osteotomy procedure (with a high speed engine, spherical surgical drills No. 8, conical drills 702, with copious irrigation with saline solution 0.9%), tooth sectioning of the crown and/or roots (with a high speed engine, zecrya surgical drill with copious irrigation and saline solution 0.9%) when indicated for the case, tooth dislocation, dental avulsion, curettage and filing and copious irrigation of the cavity with saline solution 0.9 %, absorbable polyglactin 910 suture (Vycril 4.0 - Ethicon Johnson & Johnson do Brasil Ltda. - São Paulo). Then, the surgeon will make an incision was made in the jaw tuberosity along the mesial to distal aspect in order to reach the distolingual region of the second molar, followed by intrasulcular incision surrounding the second molar to the interdental area between the second and first molar, raised the total mucoperiosteal flap, ostectomy (with chisel gouge), tooth luxation, dental avulsion, curettage and filing and copious irrigation of the cavity with saline solution 0.9%, absorbable polyglactin 910 wound suture. The duration of the surgery was noted in minutes from the time of completion of the first anesthesia to the time of final suture.
