Piezoelectric and conventional rotary techniques for mandibular impacted third molar extraction: A comparative study

Surgical extraction of impacted lower third molars exists as a popular operation performed on the oral cavity. Piezoelectric surgery presents itself as an emerging minimal-invasiveness treatment option compared to traditional rotary instruments, which have been commonly used. Therefore, it is of interest to compare the clinical efficiency, postoperative outcomes and patient satisfaction between piezoelectric and conventional rotary techniques. The study evaluated two parameters: surgical time and postoperative pain, as measured by VAS scores, along with swelling severity, trismus development and healing rates during a 7-day assessment period. An extended period of surgery using piezoelectric techniques yields better post-operative outcomes than traditional rotary techniques, characterized by reduced pain levels and swelling, as well as improved functional restoration.
