A mouthful of white teeth can help you improve your overall temperament, so many friends have gone to the hospital for consultation. They said they wanted to have a complete denture fixed. So what do you know about denture fixation? This paper introduces this in detail, and now let's take a concrete look with the authoritative experts of Shanghai Time Plastic Surgery Hospital! Expert introduction: When all the teeth are missing, you can only choose a complete denture. The retention principle of complete denture is very different from other dentures. Dentures (dentures) need to be installed in time after teeth are missing. How can dentures remain in the mouth? Denture is equipped with clasp or crown cover, which can be stuck on the real teeth in the mouth. Denture can work normally and will not fall off. However, when you implant a complete denture for a patient who has no teeth in the mouth, what retention do you rely on? Traditional theory holds that complete denture is maintained by negative pressure and adsorption. Specifically, the base of complete denture is closely attached to the alveolar ridge mucosa covered by it, and an atmospheric negative pressure is formed between them. Saliva between the base and mucosa forms an adsorption force between them, and atmospheric pressure and adsorption force work together to form the retention force of complete denture. This is like overlapping two wet glass plates, and the negative atmospheric pressure and adsorption force formed between the glass plate-water-glass plate will make the two glass plates closely attached and difficult to forcibly separate. According to the principle of physics, the atmospheric negative pressure and adsorption force are directly proportional to the area of two glass plates. Therefore, the high and wide alveolar ridge has a larger area, which produces greater atmospheric negative pressure and adsorption force, and the denture retention effect is good. On the contrary, the low-level alveolar ridge area is small, the negative pressure and adsorption force are also small, and the retention of denture is poor.
