摘要
目的探索儿童生长发育过程中颅颌面骨骼的生长发育状况，为正畸临床诊断、治疗提供科学依据。方法调查１２５名１１～１５岁上海儿童颌面部上颌长度、下颌长度与手骨成熟度、身高及女性初潮年龄之间的关系。结果上海１１～１５岁儿童的手骨成熟度、上下颌长度及身高的增加呈现同步的趋势，女性较男性提前２年进入青春生长发育快速期，但１３岁开始男性的生长速率明显超过女性，在手骨成熟度接近１００％区域身高及下颌长度仍保持很大的生长潜力。结论儿童的手骨成熟度。
Objective To research the intrinsic relationship in the growth and development progress of adolescents and to provide scientific basis for orthodontic diagnosis and treatment. Methods Sample included 125 Shanghai adolescents between 11￣15 years old, and the relationship among maxillary length, mandibular length, ossification of finger's bone, body height and the age of first coming of menstruation on female was studied.Results The ossification of finger's bone, the increase of maxilla and mandibular lengths and the body height of Shanghai adolescents between 11￣15 years old keep the same pace tendency. Female goes into the young quick growing period 2 years earlier than male, but from about 13 years old the growing speed of male is apparently more quick than that of female. When the ossification of finger's bone is nearly 100%, the body height and the mandibular length of male still possesses great growing capacity. The age of sesamoid bone appearance for both male and female and the age of first coming menstruation for female are getting earlier when comparing with others regions. Conclusion There is a close relationship among ossification of finger's bone , maxilla and mandibular lengths and body height of adolescents. Understanding the intrinsic rule correctly has the guiding significance to early diagnosis and treatment in clinical orthodontics.
