前牙

Results There were obvious mandible changes such as the increase of SNB angle and decrease of ANB angle and overjet after treatment with Twinblock, suggestive of mandible growth, increase of facial angle, reduction of mandible process angle, mild adduction of upper incisors, and mild anteversion of lower incisors.

结果 矫治前后下颌骨的变化具有统计学意义，表现在SNB角的增大和ANB角、OJ的减小，提示下颌骨的生长、面角增加和颌突角减小，上前牙轻度内收和下前牙少量前倾。

Results: The average value of periodontal attachment level in the healthy adults was 5.03 mm in incisor zone, 2.93 mm in bicuspid zone, and 3.45 mm in molar zone.

结果 ：健康成年人牙周附着水平平均值前牙区为 5 。0 3mm、双尖牙区为 2 。93mm、磨牙区为 3.45mm。

The model of a standard maxillary central incisor restored with cast post and porcelain crown was constructed through three dimensional finite element methods .

运用三维有限元法构建解剖标准前牙桩冠修复体模型，并模拟不同牙合接触形式进行加载以分析剩余牙本质应力。

Objective To explore the clinical curative effect of Frank1 Ⅲ in orthotherapy for anterior malocclusion.

目的 研究FrankelⅢ矫治器对前牙反牙合的临床治疗效果，为临床治疗反牙合提供帮助。

It has many harmful influences on both psyche and function of stomatognathic system. Therefore the study of its diagnosis, treatment and prognosis were always focused on in Orthodontic area. By now the perioral force of the preadolescent children with anterior crossbite havent been reported both in our country and other countries.

有关替牙期反口周力的研究国内外尚未见报导，本课题应用自行研制的口周力测量系统对该期患者口周力进行了研究，并对其矫治前后口周力值的变化做一对比研究，以期深入了解口周软组织与前牙反之间的内在的关系，为替牙期反的预防和临床治疗提供理论指导。

Methods: 62 cases with anterior deep overbite were treated with a modified appliance which was composed of four parts-the anterior bite plate,the anchorage on the second molars,the rectangular wire with higher elasticity and intermaxilla traction.

该矫治方法由前牙平导板、高弹性方弓丝、第二磨牙设计支抗、后牙颌间垂直牵引等组成。结果：经临床应用2 年，共62 例，效果良好。平均疗程4 个月。

The mechanism was to lead mandibular retrusion and accelerate forward growth of the maxillary.The relief of anterior crossbite combined with the retrusion of condylar and mandible led to the reconstruction of TMJ and nerve- muscles .

前牙反锁结的解除并结合将前伸的踝突、下颌诱导后退，使TMJ、神经肌肉及相关骨骼发生适应性改建，恢复并稳定于正常的关节位，有利于恢复和建立后牙的正常ICP。

A .019 multi-strand wire is placed behind the lower anterior teeth (and into the mesial fossa of the bicuspids in extraction cases) and secured with a strong adhesive to each of the anterior teeth.

阿0.019多钢绞线放在背后的低前牙（进入内侧窝的bicuspids中提取例）和担保，以强有力的粘合剂的每一个前牙。

All findings indicated that Angle Ⅲ skeletal anterior crossbite can be corrected successfully with reverse TBA combined maxillary protraction.

认为反式TBA联合前牵对上下颌软组织作用均较大，是矫治前牙反牙合的理想装置。

The cephalometric radiography and ultrasound image of swallowing were recorded just before and after anterior teeth retraction. All the changes and correlation between the variable of anterior teeth and the variable of tongue movement during swallowing were all discussed. The result showed that there was no significant change on duration and magnitude during swallowing after anterior retraction.

以13位符合条件的志愿者为受测对象，分别在前牙退后之前后各取一次测颅X光片及超音波吞咽之影像资料；而后以测颅X光片描绘取得前牙距离、角度的改变比率，另以电脑辅助分析超音波吞咽影像，得到舌头吞咽各分期的时间振幅之改变比率，再进行统计分析。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
