GROWTH AND DEVELOPMENT OF THE HUMAN HEAD

研究小组将致力于阐明更多关于 遗传学在面部外貌发展中的作用。 一样 重要的是环境因素对 颌面发育 它应该帮助我们变得更有知识 关于儿童面部各个部分的界面 成长为一张成熟面孔的过程。 规范性数据将 制定了美国黑人急需的面部生长标准， 作为一个指南，整形外科医生，颌面 外科医生、儿科医生和其他内科医生、牙医和保健医生 专业人士治疗美国黑人。 该研究将量化 两个民族面部形态的相似性 美国的黑人和白人。 文件还将提出 这两组人面部特征的差异。 三 第三磨牙发育和萌出的三维研究将是 在纵向的基础上。 它应该是第一个三维的 第三磨牙萌出和阻生的纵向研究 行政当局应制定 这些标准将使临床医生能够科学地确定何时 拔第三颗臼齿，什么时候把它们留在原位。 本研究将 进一步阐明遗传学在发展中的作用， 错牙合畸形和环境所起的作用。 建议该委员会确定 可以预防的咬合不正的类型， 需要做矫正手术 数据将数字化和计算机化。 这项研究将进一步提高计算机在正畸中的应用 诊断和治疗计划。 它应该改善预防性 口腔和面部结构的治疗方面，以改善 功能和美容目的。 它应进一步减少 做不必要的手术拔除第三磨牙

The research team will aim to elucidate more information on the role of genetics in the development of the physiognomy of the face. Equally as important will be the effects of the environmental factors on maxillo-facial development. It should help us to become more knowledgeable about the interface of the individual parts of the face of the child along the development course of becoming an adult face. Normative data will be developed to give much needed facial growth standards on American Blacks to serve as a guide to orthodontics, plastic surgeons, maxillo-facial surgeons, pedodontists and other physicians, dentists and health care professionals treating American Blacks. The study will quantify the similarities of the morphology on the facial region of the two ethnic groups in the United States, i.e. Blacks and Whites. It will also identify the differences in the physiognomy of the face of the two groups. A three dimensional study of the development and eruption of third molars will be done on a longitudinal basis. It should be the first three dimensional longitudinal study of third molar eruption and impaction. It should set standards that will allow clinicians to scientifically determine when to extract third molars and when to leave them in place. This study will further elucidate the role played by genetics in the development of malocclusions and the role played by the environment. It should determine the types of malocclusions that can be prevented and those that will require corrective surgery. The data will be digitized and computerized. This study will further enhance the use of computers in orthodontic diagnosis and treatment planning. It should improve on the preventive aspects of treatment of the oral and facial structures to improve on function and for cosmetic purposes. It should further reduce the amount of needless surgery being done to extract third molars.
