简要总结
This randomized controlled clinical trial aims to evaluate the efficacy of the Er:YAG laser in the removal of impacted mandibular third molars compared to the conventional surgical technique. The study assesses surgical efficiency, postoperative pain, swelling, trismus, and overall patient recovery. The goal is to determine whether the Er:YAG laser provides a safer and less traumatic alternative to traditional bone-cutting methods during third molar surgery.
详细描述
Impacted mandibular third molars are among the most commonly extracted teeth, and conventional surgical removal often involves bone cutting using rotary instruments, which may increase postoperative morbidity. Laser-assisted surgery, particularly using the Er:YAG laser, has been proposed as a minimally invasive alternative with potential benefits such as reduced thermal damage, improved healing, and less postoperative discomfort.
This study compares Er:YAG laser-assisted bone removal with the conventional bur technique in terms of operative time, intraoperative ease, and postoperative outcomes including pain, edema, and trismus. Patients meeting the eligibility criteria are randomly allocated into two groups: a laser-assisted surgery group and a conventional surgery group. Standardized measurements and follow-up assessments are conducted to evaluate clinical outcomes and determine the effectiveness and safety of the Er:YAG laser in third molar surgery.
