摘要
目的利用锥形束计算机断层成像(CBCT)对成年人群尖牙窝区解剖结构进行测量分析,为不同骨面类型的前磨牙区种植提供一定指导。方法选择2016年1月至2017年12月于上海建工医院、上海市同仁医院口腔科拍摄上颌骨CBCT的前磨牙缺失成人患者106例,根据上下颌的相对位置关系,从矢状方向将侧貌分为Ⅰ、Ⅱ、Ⅲ类面型3类,模拟植入直径分别为3.3mm和4.1mm的种植体,分析不同骨面型尖牙窝、种植体的位置关系。结果Ⅰ、Ⅱ、Ⅲ类面型第一前磨牙区骨倒凹测量深度之间差异有统计学意义(P<0.05);Ⅰ类、Ⅱ类、Ⅲ类面型第二前磨牙区骨倒凹测量深度之间差异有统计学意义(P<0.05);不同性别、牙齿是否缺失尖牙窝区骨倒凹测量深度差异无统计学意义(P>0.05);第一前磨牙区与第二前磨牙区可用骨高度、拟植入种植体长度差异有统计学意义(P<0.05);不同性别前磨牙区可用骨高度、拟植入种植体长度差异无统计学意义(P>0.05);牙齿未缺失患者可用骨高度、拟植入种植体长度明显大于牙齿缺失患者(P<0.05);男性患者第一前磨牙、第二前磨牙A、B、C点到牙槽嵴顶的垂直距离明显大于女性(P<0.05);牙齿未缺失患者第一前磨牙、第二前磨牙A、B、C点到牙槽嵴顶的垂直距离明显大于牙齿缺失患者(P<0.05)。结论对于成年患者尖牙窝区实施牙齿种植术,尤其是Ⅲ类面型患者,术前需利用CBCT对于尖牙窝及种植体的位置进行分析,以避免唇侧穿孔的发生。
Objective To use the conical beam CT （CBCT） to measure and analyze the fangs fossa region anatomical structure of the adult population to provide some guidance for the planting of the premolar area of different bone surface types. Methods The maxillary bone images in 106 adult patients with premolar missing were selected in the stomatology department of Shanghai Jiangong Hospital and Shanghai Municipal Tongren Hospital from January 2016 to December 2017,and the surface profiles were divided into the surface type Ⅰ,Ⅱand Ⅲ from the sagittal direction according to the relative position relations of upper and lower jaws.The simulated implant diameters were 3.3 mm and 4.1 mm of implant.The position relations of different bone surface types of fangs fossa and implant were analyzed. Results The bone undercut measuring depth of the first premolar area had statistical difference among the surface type Ⅰ,Ⅱ and Ⅲ （ P 〈0.05）;which of the second premolar area had statistical difference among the surface type Ⅰ,Ⅱ and Ⅲ （ P 〈0.05）;which had no statistical difference between different sexes and whether the fangs fossa missing （ P 〉0.05）;the available bone height and implant length had statistical difference between the first premolar region and second premolar region （ P 〈0.05）;the available bone height of premolar region and implant length had no statistical difference between different sexes （ P 〉0.05）;the available bone height and implant length in the patients without teeth missing were significantly greater than those in the patients with teeth missing （ P 〈0.05）;the vertical distance from the point A,B and C of the first premolar and the second premolar to the alveolar ridge crest in male patients was significantly greater than that in female patients （ P 〈0.05）;which in the patients without teeth missing was significantly greater than that in the patients with teeth missing（ P 〈0.05）. Conclusion Implementing the teeth implant in fangs fossa region o
