In fact, everything can be done very well. Porcelain crown is a very conventional technique. What is needed is the doctor's careful production at every step, the preoperative design of abutment shape, and the accurate positioning of what abutment needs grinding. The doctor needs to prepare the abutment into a standard column with a hard shoulder, and the width of the shoulder should meet the requirements, which should be the thickness of the edge of the porcelain crown. This is much easier than carving a pattern on jade, mainly because it is meticulous. Of course, this is also related to the doctor's environment and the number of patients on that day. So it is recommended to do it nearby, but the process must be carefully identified and done well. And the questions you asked. The price of porcelain crowns varies greatly, even for nickel-chromium porcelain crowns, there is a price difference of 200-500. It is suggested that the best price should be selected on the premise of paying attention to the details of maintenance. At present, there are some standards for making porcelain teeth, but there are no clear regulations in the country. You can send photos before, during and after surgery, and let the doctor help you identify whether it is reasonable. Only in this way can you ensure that the porcelain crown you made is not only reasonable in price, but also has no sequelae.
