Dental implants mainly consist of implants, abutments, porcelain crowns and retaining screws. The implant is surgically placed in the tooth socket in the missing area. After 2-3 months of fusion of the metal root with the surrounding bone tissue, the implant will be able to support the upper porcelain crown securely and look and function like a natural tooth. In brief, dental implants have the following more outstanding results. The main advantages of dental implants are the following 6 points: 1. Comfortable and beautiful Dental implants do not need to be fixed with the help of abutments and rings and other structures, their appearance and function are exactly the same as the real teeth. Of course, dental implants should be maintained with the same care as real teeth in order to prolong the life of dental implants as much as possible. 2. A wider range of indications With the continuous development of dental implant technology, the indications of dental implants have been broadened, and almost any missing tooth can be restored with implants. Even if there are no teeth in the whole mouth, the implant can still be used to restore a fixed denture for patients with missing teeth. 3.Protection of neighboring teeth Dental implants are placed in the alveolar bone of the missing teeth, and porcelain crowns are placed on the artificial roots, which have their own independent roots and do not need to rely on the neighboring teeth for retention. Dental implants, like real teeth, consist of two parts: the root and the crown. The implant (i.e., artificial root) is made of pure titanium with good biocompatibility and is connected to the alveolar bone through osseointegration, which is very strong and can be rooted in the patient’s mouth like real teeth. 5.Protection of alveolar bone Dental implants play a very good role in protecting the entire alveolar bone, human teeth and trees, trees have deep roots in order to flourish, after the loss of teeth alveolar bone is like soil erosion, alveolar bone will have different degrees of disuse atrophy and resorption. The artificial root of dental implant is deeply planted in the alveolar bone, so it can effectively prevent the alveolar bone from shrinking and resorption. Natural teeth transfer the chewing pressure in the mouth to the alveolar bone through the roots, while dental implants transfer the chewing pressure to the alveolar bone through the artificial roots (implants), the biomechanical principle is the same, so it can withstand strong forces and chewing efficiency is greatly improved compared with traditional dentures. In addition to dental implants, there are other well-known methods of restoring missing teeth, such as removable dentures and porcelain teeth, but these two methods are difficult to achieve the feeling of natural teeth, only dental implants are closer to natural teeth. One of the biggest functions of teeth is to chew and grind food, so the bite force of teeth is very important. According to statistics, movable dentures can only restore 30-40% of the bite force of natural teeth, and porcelain teeth can only restore 60% of the bite force of natural teeth. Dental implants, on the other hand, can fully restore the bite force of natural teeth.
