临床医师对正畸治疗与牙周的关系看法不同。有人认为正畸治疗对健康的牙周组织无永久性损害;一些人认为正畸可引起早期的龈周围炎和牙龈萎缩;还有人认为对牙周组织有利。简单前牙反(牙合)的矫治是通过上前牙唇侧移动、下前牙舌侧移动达到治疗目的。已有报道下前牙舌侧移动其对牙龈及牙槽高度是有利的,而上前牙反(牙合)则相反。本研究的目的是探讨简单上恒前牙反(牙合)正畸治疗时唇向移动对牙龈的影响。 研究对象为28例简单前牙反(牙合)儿童,男13例(平均12.7岁),女15例(平均12.3岁),每例均有一个不同部位的前牙反(牙合),以对侧牙作对照。矫治方法,13例用活动矫治器,4例用固定矫治器,11例二者联合使
Clinicians have different views on the relationship between orthodontic treatment and periodontal disease. Some people think orthodontic treatment of healthy periodontal tissue without permanent damage; some people think that orthodontics can cause early peribronchitis and gingival recession; there are others that the periodontal tissue benefits. Simple anterior teeth (Occlusal) orthodontic treatment is through the front lip movement, the anterior lingual movement to achieve the purpose of treatment. It has been reported that it is advantageous to move the lingual side of the anterior extremity to the height of the gums and alveoli, while the reverse occlusion of the anterior teeth is the opposite. The purpose of this study was to investigate the effect of lip movement on the gums during simple orthodontic treatment of orthodontic treatment. The subjects were 28 simple anterior occlusion children, 13 males (average 12.7 years) and 15 females (mean 12.3 years) with anterior anterior occlusal Contralateral teeth for the control. Correction methods, 13 cases with active appliance, 4 cases with fixed appliance, 11 cases both combined
