Abnormalities in the maxillary frenum may lead to esthetic or functional limitations and need to be corrected with a surgical intervention called frenectomy. The aim of the study was to compare frenectomies performed using Er:YAG laser technology with those using a conventional scalpel technique. Comparisons were of patients' experiences, treatment times, bleeding during treatment and wound healing.
The trial was performed as a prospective, randomized and controlled, single-blind investigation. A total of 40 patients requiring frenectomy were randomly assigned to groups which underwent either conventional or Er:YAG laser treatment. Patients' experiences, treatment time, bleeding and wound healing were evaluated immediately after surgery and 5 days, 12 days and 3 months after surgery.
Significant increase in time spent in surgery and bleeding was seen with conventional scalpel surgery. Directly after surgery the wound area was significantly larger in the laser group but at the 5-day evaluation no difference could be observed between the groups. Finally, patients were satisfied with both methods, giving them the same assessments.
In the frenectomy procedure, laser surgery is faster and causes less bleeding and may be advantageous in frenectomies.
上颚系带异常可能导致美观或功能受限，需要通过称为系带切除术的手术干预来纠正。本研究的目的是比较使用 Er:YAG 激光技术和传统手术刀技术进行的系带切除术。比较的内容包括患者的体验、治疗时间、治疗过程中的出血和伤口愈合情况。
该试验是前瞻性、随机对照、单盲研究。共 40 例需要进行系带切除术的患者被随机分为接受传统或 Er:YAG 激光治疗的两组。术后即刻、术后 5 天、12 天和 3 个月评估患者的体验、治疗时间、出血和伤口愈合情况。
传统手术刀手术的手术时间和出血量明显增加。激光组术后即刻的伤口面积明显较大，但在第 5 天评估时两组之间没有差异。最终，两组患者都对这两种方法感到满意，给予相同的评价。
在系带切除术过程中，激光手术更快，出血量更少，可能在系带切除术方面具有优势。
