Dental implants are a new technology for restoring missing teeth. It fundamentally changes the traditional way of dental implants, using dental implants made of biomaterials and implanted in the alveolar bone as artificial tooth roots to restore single, multiple or complete tooth loss, which can well restore the normal function of the mouth and jaw and the natural aesthetics of the teeth, and it is long-lasting and has the reputation of being the “third set of human teeth”. It is known as the “third set of human teeth”. When it comes to implants, it is easy to associate it with planting crops, mistakenly believing that a dental implant is a seed that will automatically grow a new tooth, but it is not. Dental implant is actually a kind of artificial tooth, which is placed on the toothbed of the missing part of the tooth with an artificial root, also called dental implant, and after 2 or 3 months of healing, then the fabricated crown is installed on top of the artificial root to perform chewing function. It is currently the permanent solution for restoring missing teeth. Dental implants are not only a mechanical device, but also a living replacement for natural teeth, which is known as the third set of human teeth. As a bionic restoration technology close to the real teeth, dental implants have the following advantages: 1, they have independent roots (artificial roots), so it is not necessary to grind the remaining natural teeth in the mouth, which can effectively prevent the disuse atrophy of the alveolar bone caused by tooth loss; 2, dental implants are similar to natural teeth in the form of weight-bearing, which can maximize the recovery of chewing function and feel comfortable; 3, dental implants have a “natural” form. 3. Dental implants have the same perfect visual effect as “growing out of the dental bed”, which will give you a perfect smile; 4. What are the different types of dental implants? Depending on the location, dental implants can be divided into anterior dental implants and posterior dental implants; depending on the number of missing teeth, they can be divided into single dental implants and multiple dental implants, the latter mostly using the restoration form of implant bridges. If the whole mouth is missing, there are fixed implant restorations and movable implant restorations. Different types of implants have different technical requirements, for example, anterior dental implants have higher aesthetic requirements, while posterior dental implants are more focused on restoring function. The specific treatment plan will be determined by the doctor in consultation with the patient on a case-by-case basis. What are the cases of missing teeth that can be restored with dental implants? Tooth loss caused by various reasons, such as periodontitis, caries or trauma, can be restored with dental implants. In terms of the number of missing teeth, single missing teeth, multiple missing teeth, or no teeth in the whole mouth can be restored by dental implant technology. In addition, a wide range of tissue and organ defects in the maxillofacial area can also be restored with the aid of oral implant technology for pseudo-replacement. When it comes to the age of dental implants, one thing is clear: the patient should be basically mature at the time of implant treatment, i.e. 18 years old for men and 17 years old for women, which is the minimum age requirement. On the contrary, dental implants are one of the most effective ways to solve the problem of missing teeth in the elderly. The possibility of dental implants depends mainly on the patient’s physical condition, and generally speaking, as long as the patient is able to tolerate a conventional extraction, he or she can receive dental implant treatment. Among the patients who come to our unit for dental implants, many of them are over 80 years old and the treatment results are no different from those of younger patients.
