Techniques in the removal of impacted mandibular third molar: A comparative study

Abstract

Objective: Surgical removal of impacted third molar is one of the common surgical procedures carried out in Oral and Maxillofacial Surgery set up. This study aimed at clinically assessing the three different surgical techniques (lingual split, using chisel and mallet, buccal approach techniques, using rotary instruments used in the removal of impacted mandibular third molars. Materials and Methods: The present clinical study comprised of 150 impacted mandibular wisdom teeth. Patients were divided in three groups and bone covering the third molar was removed by the Lingual split technique using chisel and mallet, Buccal approach technique using chisel and mallet, and Buccal approach technique using rotary instruments. Results: Surgical time was significantly increased in bur technique. Trismus was significantly increased in lingual split technique and bur technique from buccal approach technique using chisel and mallet. Post-operative nerve injury was significantly higher in lingual split technique. Dry socket was more in patients of bur technique. Conclusion: In this study we found that lingual split technique using chisel and mallet is found to be better among all three techniques used followed by buccal approach using chisel and mallet and the buccal approach technique using rotary instruments.
