Implant denture is a new type of dental prosthetic treatment. Its research and application involves many disciplines such as basic medicine, clinical medicine, biomedicine, engineering, mechanics, and materials science. The so-called implant denture is a dental root (i.e. implant) made of artificial material that is placed in the jawbone of the missing tooth to make it heal into the jawbone, and then a denture (i.e. prosthesis) is placed on the artificial root to restore the integrity of the tooth and the function of the missing tooth. Compared with traditional denture, implant denture has the advantages of comfort, naturalness, beauty, high chewing efficiency, low foreign body sensation, no damage to neighboring teeth, etc. It is called “the third set of human teeth”, and the application of this technology is a technological revolution in the history of dentistry. What kind of patients are suitable for the treatment of implant denture? Generally speaking, patients who have difficulty in retaining the denture for various reasons or who cannot accept the traditional denture due to psychological factors can choose implant prosthesis according to the specific situation. For example, if the alveolar ridge of the missing teeth is severely resorbed (low bed), it is not possible to install a removable denture or a complete denture; if the individual teeth are missing and the alveolar ridge is normally resorbed, the patient is not used to wearing a removable denture with too large a base or is unwilling to wear a complete denture instead of grinding and changing the adjacent teeth. It is worth noting that the above-mentioned local oral conditions are the primary consideration, while the general health condition should not be ignored. Patients with serious systemic diseases, such as cardiovascular diseases, blood diseases, diabetes, osteoporosis, etc., as well as those who are nervous and fearful cannot cooperate with the surgery, are not eligible for implant surgery. With the standardization and improvement of oral implant technology, as well as the application of new bone traction and bone regeneration technology in this field, the indications for oral implants are gradually expanding and obtaining a high success rate. However, it should be noted that the success of dental implants requires close cooperation between the patient and the doctor. When a pair of dental implants is worn in the mouth after the doctor’s reasonable design, strict surgery and careful fabrication, it is necessary for the patient to carry out a series of appropriate hygienic maintenance of the restored dental implants under the doctor’s guidance to ensure the good integration of the implants with the bone and gum tissues and the health and functional recovery of the oral tissues. At the same time, the patient should receive regular follow-up visits and observations from the doctor to address any problems that arise in order to prolong the life of the implant denture. The implant denture is a restoration consisting of a dental implant and the superstructure that supports it. Dental implants, also known as substructures, are artificial roots made of artificial materials (e.g. metal, ceramic, etc.), which are surgically buried in the alveolar bone of the missing tooth site. After a period of time (usually 3-6 months), the artificial roots become osseointegrated with the surrounding bone tissue; the superstructure is connected to the implant base through various forms of connection. The main implant material commonly used today is titanium. At present, whether a single tooth is missing in the mouth, multiple teeth are missing or the whole mouth is missing, the implant denture (dental implant) can be used to restore among various dental restoration methods, dental implant should be the better choice (especially when other conventional restoration methods are not effective). It realistically mimics natural teeth, restores most of the chewing function, has better retention and is more comfortable, without plastic abutments and without the hassle of daily removal and cleaning. The mechanical connection and biological bonding between the implant and the jawbone substantially improves the retention and stability of the denture, restoring chewing efficiency to a level close to that of natural teeth; it can withstand large occlusal forces, has good support, and does not damage adjacent teeth; the small size of the implant makes it generally comfortable for the implant recipient. Studies have shown that dental implants allow patients to obtain 100% restoration of chewing efficiency, and many implants are actually more stable than real teeth. With the advent of dental implants, patients with missing teeth are finally able to eat the foods they were afraid to eat, enjoy their food, and enjoy life.
