摘要

目的研究数字化设计结合三维(3D)打印模型微创拔除复杂影响性下颌第三磨牙的临床疗效。方法:纳入2023年4月至2024年3月在北京大学口腔医学院附属口腔医院口腔颌面外科就诊的8例患者,其中男3例,女5例,年龄27至57岁。所有患者的下颌第三磨牙均与下颌管密切相关,部分牙体组织进入下颌管。术前采用数字化设计,模拟术中动力系统的牙齿分割和骨去除操作以及分割后的牙齿脱位路径,分析拔牙阻力。下颌牙、下颌管和下颌模型采用光固化树脂喷墨三维打印。在手术过程中,使用内窥镜结合三维打印模型,以微创方式拔除受影响的下颌第三磨牙。手术前、手术后 2 天和手术后 7 天对患者手术侧下唇皮肤进行了定量感官测试。同时还收集了手术时间等临床数据。对术后 2 天和 7 天的数据与术前数据进行配对样本 t 检验,以比较数据差异。结果8 名患者均顺利完成了术前设计、模型打印和微创手术。术前设计的牙齿分割数为(4.4±1.3)个,实际操作的牙齿分割数为(4.0±1.1)个。手术时间为(33.3±13.0)分钟。无一例患者术后出现下唇麻木或其他术后并发症。手术过程中,内窥镜观察到下牙槽神经血管束暴露在拔牙窝中。患者术后 2 天的压痛阈值(0.601±1.170)明显低于术前(1.251±1.109)(t=2.83,P=0.025)。结论对于复杂的下颌第三磨牙撞击性拔牙,可采用数字化设计结合三维打印模型,在内窥镜的辅助下进行微创拔牙。

[Digital design combined with endoscopic minimally invasive extraction of impacted mandibular third molars with roots in contact with the mandibular canal].

Objective: To study the clinical efficacy of digital design combined with three-dimensional (3D) printing model minimally invasive extraction of complex impacted mandibular third molars. Methods: Eight patients who visited the Department of Oral and Maxillofacial Surgery, Peking University School and Hospital of Stomatology from April 2023 to March 2024 were included, including 3 males and 5 females, aged from 27 to 57 years old. The impacted mandibular third molars of all patients were closely related to the mandibular canal, and part of the dental tissue entered the mandibular canal. Preoperative digital design was used to simulate the intraoperative tooth segmentation and bone removal operation of the power system and the segmented tooth dislocation path, and analyze the tooth extraction resistance. The mandibular teeth, mandibular canal and mandibular model were three-dimensionally printed using light-curing resin inkjet. During the operation, an endoscope was used combined with the 3D printed model to minimally invasively extract the impacted mandibular third molar. Quantitative sensory testing of the patient's lower lip skin on the operated side was performed before surgery, 2 days after surgery, and 7 days after surgery. Clinical data such as operation time were collected. A paired sample t test was performed on the 2 and 7 days postoperative data and the preoperative data to compare the data differences. Results: All 8 patients successfully completed preoperative design, model printing and minimally invasive surgery. The number of teeth segmented in the preoperative design was (4.4±1.3), and the number of teeth segmented in the actual operation was (4.0±1.1). The operation time was (33.3±13.0) min. None of the patients had postoperative numbness of the lower lip or other postoperative complication. It was observed endoscopically that the inferior alveolar neurovascular bundle was exposed in the extraction socket during the operation. The patient's pressure pain threshold 2 days after surgery (0.601±1.170) was significantly lower than before surgery (1.251±1.109) (t=2.83, P=0.025). Conclusions: For complicated impacted mandibular third molars, digital design combined with 3D printing model can be used to perform minimally invasive extraction with the assistance of an endoscope.
