【摘要】：目的： 牙不是垂直地排列在牙槽骨中,而是具有一定的傾斜方向和傾斜角度。同時(shí)臨床工作中我們也發(fā)現(xiàn)下頜前牙與頜骨前端牙槽突的傾斜方向存在著一定的角度。本研究通過(guò)對(duì)山東地區(qū)成年人群下頜牙列完整者的CBCT影像前牙區(qū)進(jìn)行測(cè)量,初步探討下頜前牙與牙槽骨在正中矢狀面上的位置關(guān)系,為醫(yī)師的臨床治療,特別是下頜前牙區(qū)的美學(xué)治療提供參考。 方法： 從山東大學(xué)口腔醫(yī)院2012年12月份至2013年12月份所拍攝的口腔CT影像庫(kù)中選取150例(男女各75例,年齡段為19-48歲)合適的CBCT影像,并分為六個(gè)組：男性下頜中切牙、男性下頜側(cè)切牙、男性下頜尖牙、女性下頜中切牙、女性下頜側(cè)切牙、女性下頜尖牙。在CBCT影像上選擇合適的矢狀面,確定標(biāo)志點(diǎn),對(duì)下頜前牙牙槽嵴頂厚度、根尖距唇舌側(cè)骨板的最短距離及下頜前牙牙槽骨厚度進(jìn)行測(cè)量；確定牙體長(zhǎng)軸和牙槽骨長(zhǎng)軸,測(cè)量下頜前牙牙體長(zhǎng)軸相對(duì)于牙槽骨長(zhǎng)軸的傾斜角度(偏向舌側(cè)為正,偏向唇側(cè)為負(fù))。使用SPSS軟件對(duì)數(shù)據(jù)進(jìn)行統(tǒng)計(jì)分析,P0.05具有統(tǒng)計(jì)學(xué)差異。 結(jié)果： (1)線(xiàn)距測(cè)量結(jié)果：男性下頜中切牙牙槽嵴頂厚度、牙槽骨厚度、根尖到唇側(cè)骨板的最短距離、根尖到舌側(cè)骨板的最短距離平均為6.54mm、7.51mm、3.36mm、4.41mm;男性下頜側(cè)切牙平均為7.28mm、8.19mm、3.67mm、4.72mm;男性下頜尖牙平均為9.11mm、10.61mm、4.61mm、6.19mm。女性下頜中切牙牙槽嵴頂厚度、牙槽骨厚度、根尖到唇側(cè)骨板的最短距離、根尖到舌側(cè)骨板的最短距離平均為6.16mm、6.72mm、2.83mm、4.13mm;女性下頜側(cè)切牙平均為6.86mm、7.35mm、3.28mm、4.26mm;女性下頜尖牙平均為8.34mm、9.17mm、3.70mm、5.68mm。 (2)角度測(cè)量結(jié)果：男性下頜中切牙、側(cè)切牙、尖牙牙體長(zhǎng)軸相對(duì)于牙槽骨長(zhǎng)軸偏向唇/舌側(cè)的角度值平均為4.77°、6.12°、5.01°,女性下頜中切牙側(cè)切牙、尖牙牙體長(zhǎng)軸相對(duì)于牙槽骨長(zhǎng)軸偏向唇/舌側(cè)的角度值平均為5.38°5.81°、6.21°。男性與女性下頜前牙牙體長(zhǎng)軸相對(duì)于牙槽骨長(zhǎng)軸偏向舌側(cè)的角度值均不超過(guò)20°,偏向唇側(cè)的角度均不超過(guò)10° (3)性別差異：男性與女性在下頜中切牙、側(cè)切牙、尖牙的牙槽嵴頂厚度、牙槽骨厚度、根尖到唇側(cè)骨板的最短距離、根尖到舌側(cè)骨板的最短距離上有統(tǒng)計(jì)學(xué)差異(P0.05)。男性與女性在下頜中切牙、下頜側(cè)切牙牙體長(zhǎng)軸相對(duì)于牙槽骨長(zhǎng)軸偏向唇/舌側(cè)的角度上無(wú)統(tǒng)計(jì)學(xué)差異(P0.05)；男性與女性在下頜尖牙牙體長(zhǎng)軸相對(duì)于牙槽骨長(zhǎng)軸偏向唇/舌側(cè)的角度上有統(tǒng)計(jì)學(xué)差異(P0.05) 結(jié)論： 下頜前牙與頜骨前端牙槽突的傾斜方向不一致,其牙體長(zhǎng)軸與牙槽骨長(zhǎng)軸存在著角度,其中80%以上牙體長(zhǎng)軸相對(duì)于牙槽骨長(zhǎng)軸偏向舌側(cè)。同時(shí)牙體長(zhǎng)軸相對(duì)于牙槽骨長(zhǎng)軸偏向舌側(cè)的角度值不超過(guò)20°,偏向唇側(cè)的角度不超過(guò)10°。 下頜前牙牙槽嵴頂厚度自下頜中切牙、下頜側(cè)切牙、下頜尖牙依次增厚,與下頜前牙頸部頰舌徑由前向后的遞增趨勢(shì)類(lèi)似,下頜前牙牙槽骨厚度亦如是。 下頜前牙根尖到舌側(cè)骨板的最短距離大于下頜前牙根尖到唇側(cè)骨板的最短距離。 牙體長(zhǎng)軸相對(duì)于牙槽骨長(zhǎng)軸偏向唇舌側(cè)的角度關(guān)系在下頜中切牙、下頜側(cè)切牙不存在性別差異,但在下頜尖牙存在性別差異。牙槽嵴頂厚度、牙槽骨厚度、根尖到唇側(cè)骨板的最短距離、根尖到舌側(cè)骨板的最短距離均具有性別差異。 同時(shí)依據(jù)CBCT可以準(zhǔn)確地提供下頜前牙在正中矢狀面上與牙槽骨的位置和角度關(guān)系,為下頜前牙的美學(xué)治療特別是種植和正畸治療提供參考,避免并發(fā)癥的發(fā)生。
[Abstract]:Purpose: the teeth are not arranged vertically in the alveolar bone but have a certain inclination and inclination angle, Degree. At the same time, we also found that there is a certain angle in the oblique direction of the mandibular anterior teeth and the anterior teeth of the jaw. In this study, the position relationship between the mandibular anterior teeth and the alveolar bone in the median sagittal plane was studied by using the CBCT image front teeth area of the complete population of the submandibular teeth of the adult population in the Shandong area, and the parameters of the clinical treatment of the physician, in particular the aesthetic treatment of the mandibular anterior teeth area, were discussed. An examination. Methods:150 cases (75 male and female,19 to 48 years of age) were selected from the oral CT image library of Shandong University Stomatological Hospital from December 2012 to December 2013, and the appropriate CBCT images were divided into six groups: male and female, male, male, female, male, female, male, female, male, female, male, female, male, female, male, female, male, female, male, female, male, female, male, female, male, female, male, female, male, female, male, female, mandibular incisor, male mandibular angle, female mandibular incisor, female mandibular incisor, female selecting a proper sagittal plane on the CBCT image, determining the mark point, measuring the top thickness of the lower anterior teeth of the lower jaw, measuring the shortest distance of the root tip and the thickness of the alveolar bone of the lower tooth of the lower jaw, and determining the length axis of the tooth and the thickness of the alveolar bone of the lower jaw; The long axis of the alveolar bone, and the angle of inclination of the long axis of the anterior tooth of the lower jaw relative to the long axis of the alveolar bone (positive and biased towards the lingual side) The data were analyzed by SPSS software. statistics The results were as follows: (1) The results of the measurement: (1) The results of the line distance measurement: the thickness of the top of the incisor, the thickness of the alveolar bone, the shortest distance between the tip and the side plate of the lip, the shortest distance between the tip and the side plate was 6.54 mm, 7.51 mm, 3.36 mm, and 4.41 mm, and the average of the male mandibular incisors was 7.28 mm, 8.19 mm, and 3.67. mm, 4.72 mm; male mandibular angle of 9.11 mm, 10.61 mm, 4.61 The shortest distance between the root tip and the side plate of the lingual plate was 6.16 mm, 6.72 mm, 2.83 mm and 4.13 mm. The average of the female mandibular incisors was 6.86 mm, 7.35 mm, 3.28 mm, 4.26 mm, and the average mandibular angle of the female was 8.34 mm, 9.17. mm,3.70 Mm, 5.68 mm. (2) Results of the angle measurement: The average angle of the long axis of the male mandibular incisor, the side incisor, the long axis of the pointed tooth relative to the long axis of the alveolar bone is 4.77 擄, 6.12 擄, and 5.01 擄. The average angle of the long axis of the tooth with respect to the long axis of the alveolar bone relative to the long axis of the alveolar bone is 5.38 擄. 5.81 擄, 6.21 擄. The angle of the male and female mandibular premolar body to the lingual side with respect to the long axis of the alveolar bone is not more than 20 擄, biased The angle of the labial side is no more than 10 擄 (3) gender difference: the male and female are cut in the lower jaw, the side incisor, the fangs The thickness of the top, the thickness of the alveolar bone, the shortest distance from the tip to the side plate of the lip, the shortest distance from the tip to the side plate of the tongue, There is a statistical difference (P0.05). The male and female are incisor in the lower jaw, and the long axis of the mandibular side incisor is inclined with respect to the long axis of the alveolar bone towards the lip/ lingual side. No statistical difference (P0.05); the angle of male and female to the labial/ lingual side of the long axis of the mandibular angle with respect to the long axis of the alveolar bone upper and lower series Conclusion: The oblique direction of the mandibular anterior teeth and the anterior teeth of the maxilla is not consistent. The length axis of the tooth and the long axis of the alveolar bone are at an angle,80% of which are the length axis of the upper tooth is inclined to the lingual side with respect to the long axis of the alveolar bone, The angle between the lower jaw and the lower jaw is greater than that of the lower jaw, the lower jaw and the lower jaw of the lower jaw are thickened in turn, and the buccal cavity of the lower jaw of the lower jaw and the buccal cavity of the lower jaw of the lower jaw are sequentially thickened. The increasing trend is similar, and the thickness of the alveolar bone in the lower jaw is also the same. The short distance is greater than the shortest distance of the front root of the lower jaw to the side plate of the lip. The angle between the long axis of the tooth and the long axis of the alveolar bone towards the side of the lip is in the lower jaw, and the lower jaw There was no gender difference in the side incisors, but there was a gender difference in the mandibular angle. The top thickness, the thickness of the alveolar bone, the tip-to-lip bone plate were the most important. The shortest distance between the root tip and the lingual plate has a gender difference, and the position and the angular relationship of the lower jaw front teeth to the alveolar bone in the median sagittal plane can be accurately provided according to the CBCT, which is the aesthetics of the mandibular anterior teeth.
