摘要： 目的: 应用锥形束CT(CBCT)测量分析下颌颊棚区适合微螺钉解剖学植入的区域位点,为临床上安全植入微螺钉提供指导。方法: 收集2018年1月—2018年10月新疆喀什地区第一人民医院口腔科诊治的62例行正畸治疗患者的CBCT影像资料,对CBCT图像进行三维重建,分别测量在第一前磨牙和第二前磨牙间(A)、第二前磨牙和第一磨牙间(B)、第一磨牙和第二磨牙间(C)的牙槽嵴顶下方3 mm(D1)、6 mm(D2)、9 mm(D3)断层骨宽度。比较不同性别、左右两侧、不同位置骨宽度的差异。采用SPSS 22.0软件包对数据进行统计学分析。结果: 下颌颊棚区不同位置骨宽度在男、女之间,左右两侧之间均无统计学差异(P>0.05)。下颌颊棚区同一位置不同距离、同一距离不同位置骨宽度差异显著(P<0.05),第一磨牙和第二磨牙间距牙槽嵴顶9 mm处骨宽度最大,为(10.62±1.38)mm,第二前磨牙和第一磨牙间距牙槽嵴顶3 mm处骨宽度最小,为(2.65±0.38)mm。结论: 下颌颊棚区骨宽度在性别、左右两侧无显著差异,但下颌颊棚区不同解剖位点差异较大,自近中向远中有增加趋势。

Abstract: PURPOSE: Cone-beam CT (CBCT) was used to measure and analyze the regional sites of mandibular buccal shed for micro-screw implantation, providing guidance for dentists to safely place micro-screws. METHODS: Sixty-two patients receiving orthodontic treatment in our hospital were collected from January 2018 to October 2018. All patients underwent CBCT examination. Three-dimensional reconstruction of CBCT images was performed in the first premolar and 3 mm (D1), 6 mm (D2), 9 mm(D3) below the alveolar crest between the second premolar (A), the second premolar and the first molar (B), between the first molar and the second molar (C) for bone width, the differences in bone width between different genders, left and right side, and different positions were compared with SPSS 22.0 software package. RESULTS: The width of bone in different positions of the mandibular buccal shed in males and females was not significantly different between the left and right side (P>0.05). The bone width of the mandibular cheek shed area was significantly different at different distances and at the same distance (P<0.05). The width of bone at 9 mm of the alveolar crest between the first molar and the second molar was the largest [(10.62±1.38) mm], while the width of the bone at 3 mm of the alveolar crest of the second premolar and the first molar was the smallest [(2.65±0.38) mm]. CONCLUSIONS: The bone width of the mandibular buccal shed area was not significantly different in gender and between left and right side, but different anatomical sites in the mandibular cheek shed area had disparity, and there was an increasing trend from mesial to distal.
