塑胶套冠,由于其颜色美观,因而成为一种较为理想的修补前牙缺损的方法。但是过去由于没有自凝塑胶管,操作技术相当繁杂,失败的机会也相当多,因而采用这种方法来修补前牙缺损的人,也就不够普遍,1955年 T.A.D.Acollett 氏发明了用自凝塑胶作套冠的方法,并且在他的操作当中,也克服了一些自凝塑胶的缺点(如颜色不稳定等),但是在他的操作中应用一种纤维玻璃与自凝塑胶结合,其目的是增加套冠的坚强度。当时我曾认为这是一种较好的方法,因为它可以节省病人的时间,同时不需要模型,系采用直接法,因此其成功的效率也得到一定保证。于是我将此一文献作为文摘,发表于中华口腔科杂志(1956年第4期315页)。介绍给口腔科的同志们,当时因无法获得纤维玻璃,且感到此法仍较复杂,同时认为纤维玻璃也不 Plastic crown, due to its beautiful color, which has become a more ideal method to repair anterior defect. But in the past because there is no self-curing plastic tube, the operation of technology is quite complicated, there are quite a lot of opportunities for failure, so using this method to repair the defect of anterior teeth, it is not universal enough, in 1955 TADAcollett invented self-curing plastic As a crowning method, and in his operation also overcomes some of the disadvantages of self-setting plastic (such as color instability, etc.), but in his operation a fiberglass was used in combination with self-curing plastic for the purpose of Increase the crown strength. At that time, I had thought that this was a better method because it saved the patient's time and did not require a model. Instead, it adopted a direct method, so the efficiency of its success was also guaranteed. So I use this document as an abstract, published in the Chinese Journal of Stomatology (No. 4, 1956 315). Introduced to the dentist comrades, was unable to obtain fiberglass, and felt that this method is still more complicated, at the same time that the fiberglass is not
