Firstly, the developing principles of the cylindrical internal helical gear are proposed through analyzing the movement and geometry requirements, which provides continuous contact between the mating gear surfaces. The tooth surface of the internal helical gear in the new gearing can be imagined as being generated by the normal section of the conjugated surface of the ball-tooth, moving along the radial projection of helix line of the tooth-root circle. Also, the proposed surface can be approximate tangent to the conjugated surface of the ball-tooth along a spacial curve.

首先，通过分析保证行星轮作螺环运动时与内斜齿轮实现连续啮合传动的运动和几何条件，提出了圆柱内斜齿轮齿面的两种形成原理：即由球齿运动包络曲面的法截面沿其齿根圆螺旋线在径向的投影进行拓展所形成的内齿面，以及与球齿运动包络曲面呈近似相切接触的等螺距齿面构成的内齿面。

During the development of dental germ, enamel matrix proteins secreted by epithelial root sheath could induce dental follicle cells to differentiate towards cementoblast and form acellular cementum finally on the surface of tooth root. Many researches of domestic and oversea scholars suggest that enamel matrix proteins could effectively induce periodontal regeneration, and the structure and function of this regenerated tissue are similar to healthy periodontal tissue. Moreover, the regeneration process is nearly the same to that of embryonic development of periodontal tissue.

自发现釉基质蛋白可诱使牙囊细胞向成牙骨质细胞方向分化并在根表面形成无细胞性牙骨质以来，国内外学者做了大量研究，结果表明釉基质蛋白能有效诱导牙周组织的再生，且这种再生组织的结构和功能更接近于健康的牙周组织，并且再生过程也与牙周组织的胚胎发育过程类似。

The gum atrophies to still cause the tooth dew outside the root, the surface of tooth root doesn't have tooth enamel quality, not only be easily worn away while brushing teeth once there being no the protection of guming, in the meantime to cold, hot and sour incitement very sensitive, the mouth cavity medical science is called "tooth essence allergy", people often mistaken for this kind of phenomenon to peep out tooth nerve to cause ache, and this is incorrect.

牙龈萎缩还导致牙根外露，牙根的表面没有牙釉质，一旦没有了牙龈的保护，不仅容易在刷牙时受到磨损，同时对冷、热、酸的刺激非常敏感，口腔医学称为&牙本质过敏&，人们常把这种现象误认为是露出牙神经导致疼痛，这是不对的。
