This study aimed to evaluate the efficacy and safety of a digitally guided dual technique during esthetic crown lengthening surgery. In addition, patient satisfaction and patient-reported outcomes were assessed.
A prospective case series study was conducted. Cone-beam computed tomography and intraoral scans were used to design surgical guides, which were manufactured via 3D printing. The primary outcome was surgical accuracy, assessed by measuring the distance between the planned and final gingival margin positions using overlapping intraoral scans. Secondary outcomes included clinical crown length, gingival margin stability, pain, and patient satisfaction. Statistical analyses were performed using multilevel linear regression models, with significance set at p < 0.05.
Ten participants (87 teeth) were treated without complications. The mean duration of surgery was 66.5 min. The overall absolute deviation was 0.56 mm (95% CI: 0.48 to 0.65) at 6 months postoperatively. Clinical crown length increased significantly from baseline to the end of surgery (p < 0.001), with minimal reduction at 6 months (p = 0.479). Patient-reported outcomes indicated mild postoperative pain and high satisfaction with esthetic results.
The digitally guided dual technique for esthetic crown lengthening surgery is safe and effective, providing highly accurate outcomes. The technique also results in excellent patient satisfaction.
The use of digitally guided dual techniques for ACL surgery enhances precision and safety, leading to highly accurate outcomes and improved patient satisfaction. This approach could be beneficial in clinical settings to ensure better esthetic and functional results.
本研究旨在评估数字化引导双技术在美学牙冠延长术中的有效性和安全性。此外，还评估了患者满意度和患者报告的结果。
进行了一项前瞻性病例系列研究。使用锥形束计算机断层扫描和口腔内扫描来设计手术导板，这些导板通过3D打印制造。主要结果是手术准确性，通过使用重叠的口腔内扫描测量计划的和最终的牙龈边缘位置之间的距离来评估。次要结果包括临床牙冠长度、牙龈边缘稳定性、疼痛和患者满意度。使用多级线性回归模型进行统计分析，显著性设定为p < 0.05。
10名参与者（87颗牙齿）接受治疗，无并发症。手术的平均持续时间为66.5分钟。术后6个月时，总体绝对偏差为0.56毫米（95%置信区间：0.48至0.65）。从基线到手术结束，临床牙冠长度显著增加（p < 0.001），6个月时减少最小（p = 0.479）。患者报告的结果表明术后疼痛轻微，对美学效果满意度高。
美学牙冠延长术的数字化引导双技术安全有效，能提供高度准确的结果。该技术还能带来极高的患者满意度。
在美学牙冠延长术（ACL）中使用数字化引导双技术可提高精确度和安全性，从而带来高度准确的结果并提高患者满意度。这种方法在临床环境中可能有助于确保更好的美学和功能效果。
