【摘要】：目的利用錐形束CT(CBCT)觀測(cè)四川籍人群副頦孔(AMF)的解剖學(xué)數(shù)據(jù),為臨床頦孔(MF)區(qū)種植手術(shù)及頦部外科手術(shù)等提供解剖學(xué)數(shù)據(jù)。方法調(diào)取890例就診于四川大學(xué)華西口腔醫(yī)院患者的CBCT資料,由一名專業(yè)口腔醫(yī)生對(duì)AMF的發(fā)生率、直徑、同側(cè)MF直徑、與同側(cè)MF的直徑比例、中心距離、相對(duì)位置及與相鄰牙的相對(duì)位置等進(jìn)行觀察測(cè)量。所有數(shù)據(jù)采用統(tǒng)計(jì)學(xué)軟件SPSS 20.0進(jìn)行統(tǒng)計(jì)學(xué)分析。結(jié)果四川籍人群AMF的發(fā)生率為6.63%,AMF及同側(cè)MF的平均直徑分別為(1.65±0.25)mm和(3.84±0.64)mm,AMF與同側(cè)MF的平均直徑比例為0.4±0.1,AMF與同側(cè)MF的中心距離平均為(5.45±0.85)mm。AMF與相鄰解剖結(jié)構(gòu)的相對(duì)位置變異較大,多位于同側(cè)MF的后下位和前上位,第二前磨牙和第一磨牙之間。結(jié)論四川籍人群AMF的發(fā)生率較高,平均直徑為1.65 mm,與同側(cè)MF及相鄰牙的相對(duì)位置多樣。臨床進(jìn)行MF區(qū)種植手術(shù)及頦部外科手術(shù)時(shí)應(yīng)注意AMF的存在。
[Abstract]:Objective to observe the anatomical data of accessory mental foramen (AMF) by conical bundle CT (CBCT) in Sichuan nationality population, and to provide anatomical data for clinical (MF) implantation and mental surgery. Methods the CBCT data of 890 patients in Huaxi Stomatological Hospital of Sichuan University were collected. The incidence, diameter, ipsilateral diameter of MF, the ratio of diameter to ipsilateral MF, and the distance between the center and the incidence of AMF were analyzed by a professional stomatologist. Relative position and relative position with adjacent teeth were observed and measured. All the data were analyzed by statistical software SPSS 20.0. Results the average diameters of AMF and ipsilateral MF were (1.65 鹵0.25) mm and (3.84 鹵0.64) mm,AMF and 0.4 鹵0.1, respectively. The average central distance between AMF and ipsilateral MF was (5.45 鹵0.85) mm.AMF and the relative position of adjacent anatomical structures varied greatly. Most of them were located in the posterior and superior position of ipsilateral MF, between the second premolar and the first molar. Conclusion the incidence of AMF in Sichuan nationality population is higher, the average diameter is 1.65 mm, the relative position of MF and adjacent teeth is various. Attention should be paid to the presence of AMF in MF area implantation and mental surgery.
