Efficacy of Hyaluronic Acid in Mandibular Third Molar Surgery Performed Using Conventional Bur Technique and Piezosurgery: A Comparative Study

Along with this, researchers have found that hyaluronan or hyaluronic acid (HA) is a biomaterial introduced as an alternative approach to enhance wound healing. 9In 1934, Karl Meyer and John Palmer isolated for the first time a glycosaminoglycan (GAG) from IntroductIonAn impacted tooth is one that is unable to fully erupt into its normal functional occlusion or location by its expected age of eruption because it is blocked by overlying soft tissue, bone, or another tooth.2][3][4] As a treatment modality, the removal of an impacted tooth is one of the most common surgical procedures performed by oral and maxillofacial surgeons. 5onventionally, impacted third molars are most frequently removed using rotary cutting instruments for bone removal, which are potentially injurious as they generate excessively high temperatures during bone drilling.This results in marginal osteonecrosis and may impair osseous regeneration and healing, and is associated with a high rate of pain and postoperative swelling. 6,7With recent advances toward minimally invasive surgery, the use of piezosurgery (piezoelectric bone surgery) has gained popularity by promising greater precision of cuts, a soft tissue sparing system for bone cutting, and supported ultrasonic microvibrations, resulting in fewer postoperative sequelae. 8oth of these techniques are commonly used, but only limited comparisons have been made between them regarding outcomes and complications.
