Lower Third Molar Impactions - Efficacy of Piezosurgery In Comparison With Conventional Rotatory Technique.
Journal Title: International Journal of Dental Science and Innovative Research (IJDSIR) - Year 2019, Vol 2, Issue 2
Abstract
Introduction The presence of an impacted or a partially impacted third molar in the mandible may have several conditions associated with it such as pericoronitis, odontogenic abscess, trismus, distal caries, periodontal pocket of the second molars, development of follicular cysts and crowding of lower incisors. Therefore, they have to be frequently extracted to prevent any of these consequences. During the disimpaction of the lower third molars, the most essential phase is the osteotomy, for which many techniques have been advocated. These techniques include usage of rotatory, chisel and mallet, and recently introduced piezoelectric technique. The innovation of piezoelectric surgery, which utilizes ultrasonic vibrations, has created an approach for precise and safe osteotomies. Piezoelectric surgery is very efficient for osteotomy because it works selectively around the soft tissues, including nerves and blood vessels, which remain unaffected. It is ideal for complicated or complex surgeries where soft and delicate structures are very close to the osteotomy sites; this is due to its ability to cut mineralized structures. In Maxillofacial surgery, it has been used for sinus augmentation and more recently it has been used for third molar surgeries.1 Piezosurgery has a significant disadvantage of a longer operating time, which may cause more discomfort in the post-operative period. However, the conventional rotatory method contributes significantly to post-operative trismus, edema and paraesthesia which leads to delayed healing; the advantage of piezosurgery is that it uses ultrasonic micro-vibrations to cut bone effectively with minimal damage to the surrounding soft tissue, which promotes rapid post operation wound healing. We compared the piezosurgery with rotatory technique for osteotomy in the removal of impacted lower third molars in terms of intra-operative time, post-operative healing, post-operative pain, post-operative trismus and post-operative swelling.
