背景：研究发现年龄和牙龄在预测骨骼成熟度方面有一定的局限性。<br> 目的：采用颈椎骨成熟度评价系统比较处于生长发育期的骨性Ⅰ，Ⅱ类错牙合男性女性患者的下颌骨长度。<br> 方法：选取在新疆医科大学第五附属医院口腔科就诊并拍摄头颅侧位片的160例年龄在8-15岁的Ⅰ类错牙合(男，女各40例)，Ⅱ类错牙合(男，女各40例)骨性错牙合畸形患者，采用颈椎骨成熟度评价法(Hasse和Farman法)对样本进行分期，然后分别测量其下颌骨长度，采用独立样本t检验对骨性Ⅰ，Ⅱ类错牙合男性女性患者的下颌骨长度进行比较。<br> 结果与结论：在骨成熟度的早期，骨性Ⅰ类错牙合患者的下颌骨长度较骨性Ⅱ类错牙合患者长(P <0.05)；骨性Ⅰ类错牙合畸形患者在加速期、过渡期和减速期，男性患者下颌骨的长度比女性患者长(P <0.05)。骨性Ⅱ类错牙合畸形患者在加速期、过渡期和减速期，男性患者下颌骨的长度比女性患者长(P <0.05)。表明性别不同导致的下颌骨长度的差异性几乎存在于骨成熟度各分期，但对于骨性Ⅱ类错牙合女性患者而言，在生长发育后期会出现一段“显著增长期”。提示正畸医师正确利用这段时期进行矫治可以起到事半功倍的效果。
揹景：研究髮現年齡和牙齡在預測骨骼成熟度方麵有一定的跼限性。<br> 目的：採用頸椎骨成熟度評價繫統比較處于生長髮育期的骨性Ⅰ，Ⅱ類錯牙閤男性女性患者的下頜骨長度。<br> 方法：選取在新疆醫科大學第五附屬醫院口腔科就診併拍攝頭顱側位片的160例年齡在8-15歲的Ⅰ類錯牙閤(男，女各40例)，Ⅱ類錯牙閤(男，女各40例)骨性錯牙閤畸形患者，採用頸椎骨成熟度評價法(Hasse和Farman法)對樣本進行分期，然後分彆測量其下頜骨長度，採用獨立樣本t檢驗對骨性Ⅰ，Ⅱ類錯牙閤男性女性患者的下頜骨長度進行比較。<br> 結果與結論：在骨成熟度的早期，骨性Ⅰ類錯牙閤患者的下頜骨長度較骨性Ⅱ類錯牙閤患者長(P <0.05)；骨性Ⅰ類錯牙閤畸形患者在加速期、過渡期和減速期，男性患者下頜骨的長度比女性患者長(P <0.05)。骨性Ⅱ類錯牙閤畸形患者在加速期、過渡期和減速期，男性患者下頜骨的長度比女性患者長(P <0.05)。錶明性彆不同導緻的下頜骨長度的差異性幾乎存在于骨成熟度各分期，但對于骨性Ⅱ類錯牙閤女性患者而言，在生長髮育後期會齣現一段“顯著增長期”。提示正畸醫師正確利用這段時期進行矯治可以起到事半功倍的效果。

BACKGROUND:Age and dental age are shown to have some limitations in predicting skeletal maturity. <br> OBJECTIVE:To compare the mandibular length in boys and girls with Class I and Class II skeletal patterns by using the cervical vertebrae maturation, and to provide valid reference index for orthodontical treatment. <br> METHODS:The lateral cephalograms of the 160 cases of Class I (40 males and 40 females) and Class II (40 males and 40 females) skeletal patterns, aged 8-15 years, were taken before orthodontic treatment. The sample was grouped according to stages of the cervical vertebrae maturation (Hasse and Farman method), and the mandibular length was measured separately. The results were statistical y analyzed by the independent-sample t test. <br> RESULTS AND CONCLUSION:No matter you are a male or female, the mandibular length of Class I was greater than that of Class II at the early stages of growth and development. In the Class I pattern, the mandibular lengths of boys were greater than those of girls at accelerated, transition, and deceleration stages (P<0.05), whereas in the Class II pattern, the mandibular lengths of boys were greater than those of girls at accelerated, transition, and deceleration stages (P<0.05). The present results indicate a sexual dimorphism in the mandibular length at almost al stages of bone maturation, but the possibility of a later“catch up”growth period occurs on Class II girls. And this information has important orthodontic clinical implications.
