A dental implant is an artificial tooth. Clinically, the doctor first places an artificial tooth root, also called a dental implant, in the patient’s toothbed at the site of the missing tooth. After a healing period of 3 months, a fabricated crown is then installed on top of the artificial root to perform the chewing function of the tooth. This method is currently the international permanent solution for restoring missing teeth. The artificial root is able to completely integrate with the bone tissue after being implanted in the dental bed, and becomes part of the body. I. Key Technology of Dental Implants The dental implant, which is the artificial root, should be able to completely integrate with the surrounding alveolar bone after being implanted in the dental bed. The dental implant material should meet the following basic requirements: it should have good biological safety, that is, it should have no toxic side effects and no carcinogenic and teratogenic effects on the human body; it should ensure that the bone tissue grows together with it, which is a higher requirement for the biological material. At present, pure titanium material is the material of choice for implants, and almost all mainstream implant systems are made of pure titanium metal. The pure titanium metal is biocompatible and can exist and function in the body in a long-term, stable and harmless manner. At present, millions of dental implants are used worldwide every year to solve the pain of missing teeth for patients, and a large number of clinical application cases have been over 30 years. II. Shortcomings The main problem is the long treatment period of dental implants, which takes 3~6 months, during which you need to come to the hospital 3~5 times. In addition, the cost of dental implant treatment is higher than that of traditional porcelain teeth. The cost of dental implants depends on the dental implant treatment plan, specifically the number of dental implants, the brand of implant and the type of restoration above the implant. Patients can also choose according to their financial situation. The cost of a dental implant can range from thousands to tens of thousands of dollars depending on the brand of the implant and the type of restoration. If local bone grafting surgery, maxillary sinus lift surgery, etc. is required, the cost will increase by thousands of dollars accordingly. III. Application Various causes of missing teeth, such as periodontitis, carious disease or trauma, can be restored by dental implants. In terms of the number of missing teeth, a single missing tooth, multiple missing teeth, or a whole mouth without teeth can be restored by dental implant technology. In addition, extensive tissue and organ defects of the maxillofacial area can also be restored with the aid of oral implant technology for pseudo-replacement. Patients 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 basic minimum age requirement. As for the maximum age there is no absolute limit, on the contrary, dental implants are one of the most effective solutions to the problem of missing teeth in the elderly. The possibility of having dental implants depends mainly on the patient’s physical condition. Generally speaking, as long as the patient is able to tolerate a conventional extraction procedure, he or she can receive dental implant treatment. IV. Implant stage Generally speaking, implant surgery can be performed after 1.5 months of tooth extraction. Among them, the best time for dental implantation of maxillary anterior teeth extraction should be delayed appropriately by 2 to 3 months. In some specific cases, dental implants can be performed at the same time as the tooth is extracted, called immediate implants. After 6 weeks to 3 months after the extraction, the socket will gradually heal and flatten out, at which time you can visit the dental clinic for an examination to determine the specific treatment plan for the dental implant. Before undergoing the implant surgery, a general health examination is performed and the results of the examination are combined to develop a suitable implant treatment plan. The total time required for the implant depends on the type of implant and the type of upper restoration, and can be as little as a few weeks or as long as several months. Usually it takes 3 to 6 months. If bone grafting or other treatments are required, it can take longer. A detailed treatment plan will be developed and communicated to the patient prior to surgery.
