本文采用Moire测量技术,自制了M—CD—Ⅰ型牙齿立体测量仪,对28个牙位,336颗国人恒牙唇面凸度进行了初步观察,建立了国人恒牙唇面凸度的研究方法。结果表明:切牙及尖牙凸点的位置大多在牙体唇面牙冠的牙颈线略上方,近中面及远中面连线的中点处。磨牙主要位于牙冠的牙颈线略上方,略偏远中。此外还测量了从凸点至切缘、近中切角、远中切角、根尖、根分叉、近中根尖及远中根尖的距离。这些数据对临床牙体修复具有一定的参考价值。
In this paper, Moire measurement technology, self-made M-CD-Ⅰ-type dental three-dimensional measuring instrument, 28 teeth, 336 permanent heads of the Chinese people were preliminarily observed lip gloss, the establishment of Chinese permanent teeth lip gloss method. The results showed that the incisors and canine bumps were mostly located slightly above the cervical line of the dental facet and at the midpoint of the midline and distal midline. Molar mainly located in the crown of the dental neck slightly above the slightly remote. In addition, the distance from the bump to the incision, near middle incision angle, distal incision angle, apical root, root bifurcation, mesial apical root and distal apical meristem were also measured. These data have certain reference value for clinical dental restoration.
