【摘要】：目的:分析下颌下腺窝骨倒凹解剖形态,为下颌磨牙区牙种植术提供参考依据。方法:利用锥形束CT(cone-beam computed tomography,CBCT)扫描成像,分析下颌下腺窝解剖形态特点;在磨牙区模拟植入不同直径种植体,测量下颌下腺窝、下颌管及种植体相关数据,分析三者的空间位置关系。结果:第一磨牙区下颌下腺窝骨倒凹深度为(1.0±0.61)mm,第二磨牙区为(1.5±0.61)mm,性别、左右及缺牙导致的差异均无统计学意义。牙存在者第一磨牙区发生舌侧穿孔时种植体长度为(19.7±3.75)mm(d=4 mm)和(18.6±3.73)mm(d=5mm),第二磨牙区为(16.2±3.46)mm(d=4 mm)和(15.2±3.09)mm(d=5 mm),牙缺失者第一磨牙区发生舌侧穿孔时种植体长度为(17.1±3.77)mm(d=4 mm)和(15.6±3.85)mm(d=5 mm),第二磨牙区为(14.2±4.05)mm(d=4 mm)和(13.2±4.27)mm(d=5 mm),是否缺牙的差异具有统计学意义。结论:在下颌磨牙区进行牙种植手术时,通过CBCT分析下颌下腺窝、下颌管及种植体的空间位置关系,对手术具有重要指导意义。
[Abstract]:Objective: to analyze the anatomic morphology of the submandibular gland fossa and to provide reference for dental implants in the mandibular molar region. Methods: the anatomical features of submandibular gland fossa were analyzed by using cone-shaped bundle CT(cone-beam computed tomography-CBCTimaging, and the submandibular fossa, mandibular canal and implants were measured by imitating implants with different diameters in molar region. The spatial position relationship of the three is analyzed. Results: in the first molar region, the depth of the inverted fovea of the submandibular gland fossa was 1.0 卤0.61mm, and the second molar area was 1.5 卤0.61mm. There was no significant difference in sex, left, right and missing teeth. The length of implants was 19.7 卤3.75)mm(d=4 / mm and 18.6 卤3.73mm / 3.46)mm(d=4 / mm in the first molar and 15.2 卤3.09)mm(d=5 / 3.09)mm(d=5 in the second molar, respectively. The length of the implant in the first molar was 17.1 卤3.77)mm(d=4 / mm and 15.6 卤3.85)mm(d=5 / 3.85)mm(d=5 when the first molar was perforated on the lingual side) and the second molar was 17.1 卤3.77)mm(d=4 / 3.77)mm(d=4 / mm) and 15.6 卤3.85)mm(d=5 / (respectively) in the first molar and the second molar in the absence of the first molar (17.1 卤3.77)mm(d=4) and 15.6 卤3.85)mm(d=5 / mm respectively. There were statistically significant differences between 14. 2 卤4.05)mm(d=4 and 13. 2 卤4.27)mm(d=5. Conclusion: it is important to analyze the spatial position of submandibular gland fossa, mandibular canal and implants by CBCT in the mandibular molar region.
