These two kinds of circumstances will insist usage tooth gold next everyday, can get rid of the burning disease of gum top and bottom in time, protect health of gum towards atrophying gum assurance nourishment supply, thus, effectively arrestment or turn round to atrophy, thus and effectively help to roast porcelain tooth and the long-last usage of false teeth the new problem is not.

牙齿矫正，由于矫牙器的原因，多数都会引擎牙龈萎缩的后遗症，矫正过程中或矫牙后使用牙齿黄金，牙齿黄金在口含的时候可以让萎缩的牙龈直接吸收到足够营养，从而令萎缩的牙龈再生，闭合因牙齿矫正而出现的难看牙龈缝隙，避免因牙齿矫正带来的牙龈萎缩后遗症。

Non-occluding teeth with a hypofunctional periodontium have a lower rate of bone remodeling, and are more susceptible to the injury in periodontal tissues caused by orthodontic force than normally occluding teeth, such as hyalinization or undermining bone resorption, even dentin resorption.

正畸治疗中，无咬合接触的牙周膜废用性萎缩牙较正常咬合接触牙对矫治力反应差，骨改建率低，易发生玻璃样变和潜掘性骨吸收，延缓牙移动，因此对无咬合接触牙的临床治疗中应采用轻力。

Because the gum atrophies part only a tooth seldom of, usually is all one, now that have a tooth because of atrophying but shed off, periphery of tooth's appearing an atrophic risk is very big, if is a sustaining good tooth loose, will make the whole row roasted a porcelain tooth to shed off together.

因为牙龈萎缩部分很少只有一个牙齿的，通常都是一片，既然有个牙齿因萎缩而脱落，周边的牙齿出现萎缩的危险性是非常大的，如果作为支撑的好牙松脱，就会导致整排烤瓷牙一起脱落。

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。

The false teeth usually needs good solid Chi to do to prop up, but the part of general imperfection tooth, in addition to on business so collision and cause of drop a tooth, rest regardless is because the tooth week disease or shed off naturally, above 90%s all drops a tooth because the gum atrophies, this has an antinomy, if after cheating, Be roast the porcelain tooth props up of good tooth, gum also because of atrophying but loose how do?

假牙通常需要好的固齿来做支撑，但是一般缺失牙齿的部位，除了因事故碰撞而导致的掉牙，其余无论是由于牙周病或者自然脱落，90％以上都是由于牙龈萎缩而掉牙的，这就有个矛盾，如果做了假牙后，作为烤瓷牙支撑的好牙齿，牙龈也因为萎缩而松脱怎么办？

Roast the porcelain tooth usually needs good solid Chi to do to prop up, but the part of general imperfection tooth, in addition to on business so collision and cause of drop a tooth, rest regardless is because the tooth week disease or shed off naturally, above 90%s all drops a tooth because the gum atrophies, this has an antinomy, if after doing to roast a porcelain tooth, Be roast the porcelain tooth props up of good tooth, gum also because of atrophying but loose how do?

AIM: To construct a three-dimensional finite element model of human mandibular alveolar atrophy, which uses to analysis the biomechanical characters of atrophic alveolar ridge.

目的：利用螺旋CT建立牙槽嵴萎缩的下颌骨三维有限元模型，用于萎缩牙槽嵴的生物力学分析。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
