| 1. | Objective to investigate the displacements and the stress distributions of a mandibular second molar 摘要目的?解下颌第二恒磨牙不同载荷下近中移动时的位移及应力分布情况。 |
| 2. | The palatine canal is identified by palpation , usually 1 - cm medial to the second molar , and cannulated using an angled 27 - gauge needle 左右,再使用长针插入腭大孔,用利多卡因和肾上腺素来麻醉翼腭窝。 |
| 3. | Conclusions : when using the attachment prostheses to restore the type of the second molar distal - extension for the patient , we can use one teeth as abutment 结论:用该附著体修复第二磨牙末端游离缺损时,可采用单基牙。 |
| 4. | Despite of food impaction and proximal caries of first permanent molar , impacted lower second molar also affect the normal function of occlusion 除了影响正常咬合功能外,常因食物阻塞而伴随大臼齿间软组织发炎或第一大臼齿远心侧龋齿。 |
| 5. | Excessive mesial - axial inclination of the mandibular second molar or inadequate posterior arch length cause the mandibular second molar to become impacted against the distal contour of the first permanent molar 摘要下颚牙弓空间不足或第二大臼齿本身过度的近心轴向倾斜,常造成第二大臼齿前倾和阻生。 |
| 6. | A case report is presented on a 26 - year - old man had a class lll malocclusion with severe facial asymmetry , unilateral cross - bite , missing of multiple teeth and mesial tilting of multiple second molars 摘要本病例报告为一26岁骨性三类异常咬合之成年患者,同时伴随有颜面歪斜、单侧错咬、多颗牙齿缺失及多颗臼齿近心倾倒。 |
| 7. | Several methods have been proposed for unlocking impacted permanent second molar , the technique of choice would be determined by such factors as the efficiency and convenience of appliance , the preparation of anchorage and the undesired side effect 因此当发现第二大臼齿无法顺利萌发,通常会建议病患以矫正方式扶正以获得良好的咬合。 |
