After missing teeth, most people first think of removable dentures, on the one hand, because dentures are cheap, on the other hand, people's concept of dental implants is vague. When you get to the hospital, the doctor recommends you to have teeth planted, and you may still feel confused. I think the doctor deliberately recommended expensive ones to you in order to make more money, but it's not. The application scope of fixed denture is often limited by objective conditions, and at the same time, it will also cause adjacent teeth to be strained, loose and fall off. However, removable dentures can't fully restore chewing function, affect pronunciation, and have foreign body sensation, so it is difficult to satisfy friends with missing teeth. Moreover, dentures lead to the ubiquitous loss of healthy teeth on both sides. So this is the emergence of dental implant restoration technology, which avoids many disadvantages of porcelain teeth and movable teeth in the past, such as gingival bleeding, black line and so on. It implants bionic root in the edentulous area, directly transfers the biting force to the bone bed, protects the adjacent teeth and alveolar bone, and is as firm, stable and beautiful as real teeth.
