A very significant feature of the traditional method of filling in the clinic is that, after many fillings, the missing teeth are getting bigger and bigger. Teeth just filled in a few days, but because of chewing harder things, fillings into the silver mercury material fell out of a large piece; with a toothpick to fiddle with the food embedded in the teeth, along with fillings together with the fillings dialed out, non-stop embedded food, and constantly with a toothpick, as a result, the hole is getting bigger and bigger at that time, silver mercury fillings have been the best way to fill the teeth in the country. Inlays are a kind of restorations embedded inside the dental cavity to restore the form and function of the missing tooth. It is to prepare the affected tooth into a certain shape of the cavity, and then according to the shape of the cavity to make different materials of the restoration. The materials used to make inlays vary according to each person’s dietary habits and individual tooth condition, with the harder gold inlays and the more aesthetic porcelain inlays being the two most commonly used. “Inlays” are customized restorations for the teeth, through the adhesive will be bonded to the missing teeth, due to the inlays in the form, hardness and other aspects of the teeth and the degree of good match, so % of the inlays can be used for more than 10 years, which not only solves the problem of the missing part of the teeth is easy to get bigger, but also reduces the patient’s pain of frequent fillings. This not only solves the problem of the missing part of the tooth getting bigger, but also reduces the pain of frequent fillings. The vast majority of people who have had fillings will have food taboos, many food eaten in the mouth after embedded in the teeth of the small holes, painful and intolerable. On many occasions, people have to figure out which foods won’t be eaten in the mouth but will be embedded in the teeth while trying to figure out how to gracefully remove those accidentally embedded foods. In the face of such embarrassment and pain, there is only one explanation – there is nothing we can do, who let us ever fillings? Over time, it has become normal to have food embedded in your teeth after a filling. Aside from a spotlight, the entire process of filling a tooth relies only on the doctor’s personal experience. Due to the limitations of light and vision, how much area is missing and which part of the tooth is a little more difficult to grasp, which makes it more difficult for the doctor to fill the missing part with silver mercury. This makes it more difficult for the doctor to fill the missing portion with silver mercury. Eating inlays are also a result of the silver mercury filling being too large and blocking the gaps between the teeth that allow food to flow normally. The use of inlays solves this problem by taking a mold of the tooth to be filled. The doctor will first take a mold of the tooth to be filled, taking into account the occlusal relationship of the upper or lower teeth and the surrounding teeth, and then make a mold of the missing portion of the tooth, which is called an inlay. Not only is it the same size as the missing portion of the tooth, but it is also the same size in terms of concavity and convexity, so that the tooth and the inlay fit together well and the natural gap between the teeth is preserved, so that eating will never be embedded again. What is “inlay”, I’m afraid that the vast majority of people are still confused, after all, inlays in China to promote the time is not long, inlays in foreign countries has long been a widely carried out oral diagnostic and treatment programs, its durability and safety has been recognized by many countries. In our hospital stomatology department, inlays have been used to solve the trouble of filling and replenishing for many people, and every step of the treatment is carried out according to strict standards. We hope that we can spread the concept of scientific dental treatment, and we also hope that no matter what kind of pain our patients walk in with, they leave with a smile on everyone’s face.
