以往在研究初期打开咬合机制时,很少涉及到下颌骨的旋转生长,而本文研究目的是探讨矫治ClassⅡ类Ⅰ分类错(牙合)伴发深覆(牙合)时下颌骨的生长变化,以及这些变化在深覆(牙合)治疗中的意义。所述病例除1例用Activator矫治器外,均用Begg细丝弓技术矫治。研究方法为:描绘并重迭头侧位片,对准S点重迭SN,对准ANS重迭ANS——PNS,下颌骨内部结构也相重迭。作者从以下三方面进行分析。初期打开咬合作者在病例报告中指出,在无生长发育的个体或下颌骨向后旋生长趋势的长面型患者,切牙压低是治疗深覆(牙合)的主要目的。生长发育中的个体,伴有深覆(牙合),下颌骨向前旋转生长,则切牙压低和磨牙
In the past in the early stages of the study to open the occlusal mechanism, rarely involved in the mandibular rotational growth, and the purpose of this study is to investigate the Class Ⅱ Class Ⅰ malocclusion with deep overbite (occlusal) growth changes in the mandible, And the significance of these changes in deep overbite therapy. Except for 1 case of Activator appliance, the cases were treated with Begg filament arch technique. The research methods were: depicting and overlapping the head flaps, aligning the S overlap SN, aligning the ANS overlap ANS - PNS, the internal structure of the mandible also overlap. The author analyzes from the following three aspects. Initial open bite The authors report in a case report that the reduction of incisors is the primary goal of treating deep overbite in long-sided patients with non-growing individuals or mandibular spinosylation. Growth and development of individuals, accompanied by deep overbite (occlusal), the mandible forward rotation growth, the incisor pressure and molars
