Introduction: Third molar surgery is one  of the most commonly performed procedure. Conventionally the surgical handpiece with bur is employed for osteotomy and odontectomy.  Piezosurgery offers distinct advantage.  The present study was to compare the surgical and postsurgical outcomes of third molar removal using piezoelectric surgery and rotary bur. Aim and Objectives: 1.To compare the duration of the surgery using piezoelectric and  surgical osteotomy technique. 2.To evaluate the post surgical swelling, pain and trismus between the two groups. Materials and Methods: The study consisted of 15 randomly selected patients who underwent disimpaction by conventional rotary method (group A) on one side and with piezosurgery (group B) on the contralateral side and consented for the same. Facial swelling and trismus were evaluated in both groups on the First, Third and seventh days post operatively. Pain was evaluated from post-operative days 1-7 using Visual Analogue Scale. Results: Pain was significantly lower in the piezosurgery group(B) in post operative 1st 3rd  7th day  Compared with rotary ( group A) . Facial measurements were taken preoperatively using 4 baseline (S1, S2, S3, S4) and was compared with facial swelling on 1st, 3rd, 7th postoperative day in both the groups .) There was significant reduction in swelling in piezoelectric group as compared to rotary group. The significant reduction in trismus was seen in piezoelectric (group B) on 1st, 3rd,7th day compare to group A (rotary). The Mean surgical time was longer in group B comparing to  group A. Conclusion: The piezoelectric osteotomy technique produced a reduced amount of facial swelling and trismus, as per evaluation of these parameters on the 3rd and 7th day after surgery, as well as reduced amount of post-operative pain from days 1-7.  A longer surgery time was required for piezosurgery when compared with the rotatory osteotomy technique.
Key Words: Piezoelectric surgery, impacted mandibular third molar, piezosurgery, rotatory technique.
