The growth of the maxilla in man is still debated. Many authors described an anterior part of the maxillary bone, called premaxilla distinct from the maxilla proper. This description referred to the existence in animals of an incisive or premaxillary bone which does not exist in man. Is this distinction pertinent in the human facial growth?
To settle this question, we performed a histologic study in eight embryos and fetuses aged from 40 days to 10 weeks post conceptional (PC) and an anatomic dissection of 3 palates of fetuses aged from 22 to 30 weeks PC.
We found only one maxillary point of ossification, and the growth of the anterior part of the maxilla cannot be separated from the global growth of the maxilla.
The independence of the anterior part of the maxilla in man is very limited during the growth and cannot justify the term of premaxilla.
人类上颌骨的生长仍存在争议。许多作者描述了上颌骨的前部，称为前颌骨，与上颌骨本身不同。这种描述是指动物中存在的切牙骨或前颌骨，而人类中不存在。这种区分在人类面部生长中是否相关？
为了解决这个问题，我们对8个受孕后40天至10周的胚胎和胎儿进行了组织学研究，并对3个受孕后22至30周胎儿的腭部进行了解剖。
我们仅发现一个上颌骨化点，上颌骨前部的生长与上颌骨的整体生长无法分离。
人类上颌骨前部在生长过程中的独立性非常有限，无法证明前颌骨这一术语的合理性。
