PIEZOELECTRIC VERSUS CONVENTIONAL ROTARY TECHNIQUE FOR SURGICAL EXTRACTION OF HORIZONTALLY IMPACTED MANDIBULAR THIRD MOLAR (A RANDOMIZED CONTROLLED CLINICAL TRIAL)

INTRODUCTION Impacted mandibular third molar extraction is a common procedure in dental surgery. The conventional technique involves using manual and/or rotary instruments to perform osteotomy and odontectomy, allowing dental extraction with a shorter intervention time and reduced patient anxiety.(1) New surgical techniques and innovative technologies have greatly improved the predictability and reduced the invasiveness of oral surgery procedures. Piezoelectric bone surgery (PBS) was introduced into clinical practice almost 20 years ago.(2) METHODOLOGY Sixteen patients with horizontally impacted lower third molars in class II position B (3) indicated for surgical extraction were treated randomly using either the piezosurgery (4) or the conventional bur technique. (5) Duration of the procedure, soft tissue healing, postoperative edema, trismus, pain, and bone density were evaluated. Post operative pain was evaluated as mean VAS score. (5)
