In the denture work, in order to reduce the number of visits to the wounded and sick, improve work efficiency, and better serve all the military and civilian, we improve on the basis of the original fixed bridge twice method, eliminating the wax, boxing, heat treatment, etc. Complex steps to a modeled plastic and the use of plastic products with self-curing plastic teeth combined production method, and achieved good results, are described below. First, the production method 1. Take the model: After the preparation of the abutment, take a working model and a pair of mold. The working model of the abutment first concave concave plus wax dressing, from the model of the abutment along the neck from the neck shape of the curve to the root side cut 0.5 to 1 mm, leaving the artificial crown for the extension of the neck margin. use
