乳牙列反(牙合)不治疗通常会发展为恒牙列反(牙合)。但是也有一些乳前牙反(牙合)患者从替牙期到恒前牙萌出期间,未经治疗而反(牙合)自行消失。本文对乳牙反(牙合)患者的颌骨长度变化进行研究,比较了乳前牙反(牙合)自行改正的患者与其他乳牙反(牙合)患者的差异。 作者对220名乳牙反(牙合)患者进行定期观察,从中选出符合以下标准的44例女性患者,中线无明显偏移、牙齿生理形态及数目正常,无牙旋转及治疗史。观
No treatment of deciduous teeth will usually develop anti-occlusion. However, there are also some cases of anterior crossbite (occlusal) patients who disappear by themselves without anti-occlusion (occlusion) during the eruption period from the congenital period to the permanent anterior eyelid. In this paper, the changes of jaw length in patients with deciduous teeth were studied, and the differences between patients with self-correction of the anterior deciduous teeth and those with other deciduous teeth were compared. The authors examined 220 patients with deciduous occlusion on a regular basis. Forty-four female patients who met the following criteria were selected. There was no obvious shift in the midline, normal tooth morphology and number of teeth, no tooth rotation and treatment history. View
