The Application of ultrasonic bone knife combined with turbodrill cross incision in extraction of mandibular impacted third molar

บทคัดย่อ

          The extraction of mandibular impacted third molars is a common yet complex surgical procedure in oral and maxillofacial surgery due to the close association with mandibular nerves and deep impaction. Traditional bone-chisel extraction methods, though effective, are associated with high trauma and extended recovery periods, leading to increased patient discomfort. This study aims to: (1) Explore individualized approaches for impacted tooth extraction to provide safer and faster options for the removal of mandibular impacted third molars; (2) Provide an alternative sectional extraction approach for impacted teeth in clinical oral surgery; (3) Offer new ideas and a theoretical basis for the extraction of mandibular impacted third molars in clinical practice. This study adopts a case-control research design, including 120 patients with mesioangular impacted mandibular third molars, divided into three groups: traditional bone-chisel extraction (control group) and two experimental groups using an ultrasonic bone scalpel combined with a turbine drill, with either linear or cross-shaped incision. The outcomes were analyzed for surgery time, postoperative pain, swelling, mouth-opening limitation, and complication rates.
          The results showed significant differences in surgical time, postoperative pain, and swelling among the groups. The ultrasonic bone scalpel with a cross-shaped incision provided the best outcomes, with shorter surgical times, reduced pain, and minimized swelling compared to the traditional method. The combined use of an ultrasonic bone scalpel and a turbine drill significantly reduced surgical trauma, enhanced recovery, and minimized postoperative complications. The cross-shaped incision method demonstrated particular efficacy, suggesting its potential as the preferred choice for similar extractions.
