牙萌出

Approached the central incisor eruption time is 6-9 years old, 7-11 years of age for the lateral incisor.

上前中切牙萌出的时间是6—9岁，侧切牙为7—11岁。

As long as you protect the good kid's baby tooth and make the milk sharp tooth shed off and the Heng sharp tooth harbour time of unanimouslyn and then can't influence a tiger tooth.

只要您保护好孩子的乳牙，使乳尖牙脱落和恒尖牙萌出的时间一致就不会影响虎牙。

Conclution more mesially inclined maxillary molars are likely to be associated with third molar eruption.

第三磨牙萌出与上颌第一、第二磨牙较大的近中倾斜有关。

Results Maxillary first and second molars were more mesially inclined in the first group, particularly in the younger subjects (16～25 years).

结果 上颌第三磨牙萌出组与未萌出组相比，上颌第一磨牙和第二磨牙更向近中倾斜，而且随年龄的增加倾斜度也变大。

Results Maxillary first and second molars were more mesially inclined in the first group, particularly in the younger subjects (16～25 years). This inclination increased with age.

结果 上颌第三磨牙萌出组与未萌出组相比，上颌第一磨牙和第二磨牙向近中倾斜，而且随年龄的增加倾斜度也变。

Results Maxillary first and second molars were more mesially inclined in the first group, particularly in the younger subjects (16～25 years). This inclination increased with age.

结果 上颌第三磨牙萌出组与未萌出组相比，上颌第一磨牙和第二磨牙更向近中倾斜，而且随年龄的增加倾斜度也变大。

Results maxillary first and second molars were more mesially inclined in the first group, particularly in the younger subjects (16～25 years). this inclination increased with age. the logistic regression showed that the sagittal inclination of the first molar is a predictor of the eruption of the third molar.

结果 上颌第三磨牙萌出组与未萌出组相比，上颌第一磨牙和第二磨牙更向近中倾斜，而且随年龄的增加倾斜度也变大。logistic回归结果显示第一磨牙的轴倾度是第三磨牙萌出的一个预测因子。

Methods: Fifty-fix adolescents were chosen and divided into first premolar extraction and nonextraction groups, with 30 and 26 patients respectively. The pretreatment and posttreatment panoramic radiographs were taken. The indexes of third molar eruption space, distance from third molar to occlusal plane and the length of mandible were measured and analyzed.

选择56例上下颌第三磨牙均存在的患者进行方丝弓正畸治疗，按照第一前磨牙拔除与否分为拔牙组（30例）和非拔牙组（26例），利用术前术后曲面断层片对患者上下颌第三磨牙萌出间隙、第三磨牙与胎平面的距离以及下颌长度进行测量分析。

Methods The sample consisted of 2 groups. The subjects in the first group (n = 30) had complete normal dentitions including third molars; those in the second group (n =30) had impacted right and left third molars.

研究样本分为两组，第一组的研究目的确定上颌第三磨牙萌出与第一磨牙和第二磨牙轴倾度的关系。

Objective: To study the changes of upper and lower third molar position in patients treated with first premolars extractions.

目的：研究第一前磨牙拔除后对第三磨牙位置变化的影响，探讨影响第三磨牙萌出的客观因素。
