This study investigated patients' perceptions of laser-assisted esthetic crown lengthening (ECL) for treating "gummy smiles" using either an open-flap (OF) or flapless (FL) technique. This study included 36 healthy patients with altered passive eruption who underwent ECL surgery and were randomly divided into two equal groups: OF and FL. Gingivectomy and ostectomy were performed using an Er, Cr:YSGG laser in both groups. Patients' perceptions of postsurgical morbidity were assessed using a 5-point self-administered Likert scale. The participants provided ratings on their experiences with anxiety, pain, swelling, bleeding, discomfort, tooth sensitivity, and use of pain medication after 7 days. Nine months after surgery, another survey was conducted to assess the overall satisfaction. Patients reported less anxiety, postoperative pain, swelling, bleeding, discomfort, sensitivity, and need for pain medication after the FL than the OF surgery procedure. Both groups reported high satisfaction with the final cosmetic outcome after 9 months, although patients who underwent FL surgery tended to report even greater satisfaction. The FL procedure was also significantly faster, taking approximately 15 min less than OF surgery. The FL laser-assisted ECL technique led to a more positive recovery and better patient experiences than the OF technique. This study suggests that laser-assisted FL ECL may be a more patient-friendly and efficient procedure compared to traditional OF surgery with similar esthetic results. This could be important for dentists looking to offer their patients a less invasive and potentially more comfortable option.
本研究调查了患者对使用开放式翻瓣（OF）或无瓣（FL）技术进行激光辅助美学牙冠延长术（ECL）治疗“牙龈微笑”的看法。本研究纳入了36例被动萌出改变的健康患者，他们接受了ECL手术，并被随机分为两组，每组人数相等：OF组和FL组。两组均使用铒铬：钇铝石榴石激光进行牙龈切除术和骨切除术。使用5分自评李克特量表评估患者对术后发病率的看法。参与者在术后7天对他们在焦虑、疼痛、肿胀、出血、不适、牙齿敏感和使用止痛药物方面的经历进行评分。术后9个月，进行了另一项调查以评估总体满意度。患者报告称，与OF手术相比，FL手术后的焦虑、术后疼痛、肿胀、出血、不适、敏感和止痛药物需求更少。两组患者均对9个月后的最终美容效果表示高度满意，尽管接受FL手术的患者往往表示满意度更高。FL手术也明显更快，比OF手术大约少用15分钟。与OF技术相比，FL激光辅助ECL技术带来了更积极的恢复和更好的患者体验。这项研究表明，与具有相似美学效果的传统OF手术相比，激光辅助FL ECL可能是一种对患者更友好、更有效的手术。这对于希望为患者提供侵入性更小、可能更舒适选择的牙医来说可能很重要。
