The main reason why dental implants are so popular is that they have many incomparable natural advantages compared to traditional prosthetics. Before the dental implant surgery, many people are only concerned about the service life of dental implants, but few people look for reasons from their own maintenance. So, what is the life span of dental implants in general? What is the life expectancy of dental implants in general? To understand the lifespan of dental implants, we must know what are dental implants? First of all, dental implants are placed into the jawbone, and the biting force is transmitted directly to the jawbone through the teeth to the implant, while other dental implant methods are supported by the neighboring teeth or mucosa, and the force is transmitted from the denture to the abutment teeth and mucosa to the jawbone, which leads to a huge difference in its function and nature. With good biocompatibility, it can heal together with the living bone and then come together to support the various forces from the occlusion. As a reminder, the duration of dental implant maintenance is not only related to the good or bad treatment, but actually also to the patient’s future health condition, use and self-maintenance. The latter is the decisive factor in determining the longevity of dental implants. However, with daily precautions after surgery and with good oral hygiene and regular check-ups, artificial implants can last as long as real teeth. In the past, the success rate of implants was considered to be 85% for 5 years and 80% for 10 years, but now the requirements are higher, with a success rate of more than 95% for 5 years and an average service life of 8 years for fixed restorations with fixed teeth. The average life expectancy of dental implants is 8 years. In developed countries, the 5-year retention rate of dental implants is over 95% and the 10-year retention rate is about 90%. What are the factors related to the life expectancy of dental implants? 1, the use and maintenance of dental implants: effective oral cleaning on time, after the dental implants, regular scaling, can prolong the life of dental implants; 2, advanced implant system: the more advanced the dental implant system, the higher the success rate, the longer the service life; 3, the patient’s health: systemic diseases will reduce the immunity of the oral cavity, which is not good for dental implants and natural teeth, affecting the life of dental implants; 4, the level of the doctor and technician: the doctor and technician are not good for dental implants. The level of the technician: the doctor and the technician have accumulated more than 5 years of experience in dental implants and the success rate is more than 90%. Are dental implants permanent? Is it a one-time performance solution? After the dental implant surgery, patients should pay attention to maintenance and good habits are the best way to prolong the life of dental implants. Are dental implants permanent? At present, millions of dental implants are used worldwide every year to solve the pain of missing teeth, and the longest clinical use of dental implants has exceeded 40 years in a large number of clinical application cases. The length of life of dental implants and the determining factors 1, diet life and habits. Avoid biting hard objects. Since implants are combined with bone in direct contact, without the protective effect of buffering and force feedback played by the periodontal membrane of natural teeth, excessive biting force and undesirable lateral force can lead to resorption of alveolar bone. Biting on hard objects and particularly tough foods should also be avoided in the future use process. If any abnormalities are found during use, such as inadvertent impact of the dental implant by external forces, loosening of the dental implant, redness and pain of the gums, bleeding from brushing, etc., timely consultation should be made; 2. Regular check-ups and follow-ups. Are dental implants permanent? The various structures of dental implants are connected to each other by screws or adhesives. The mechanical connection is limited by the fatigue life and mechanical properties, which can make the connection parts of the dental implant loose; the bonding connection can make the restoration loose due to the loosening or aging of the bonding agent. The loosening of parts and alveolar bone resorption is often a sign of implant overload, which requires patients to visit the hospital in time to adjust the occlusion and refix the dental implant; 3. Daily oral cleaning and care work. You can use a soft-bristled toothbrush and a micro-abrasive toothpaste to carefully clean the teeth. The adjacent surfaces and dead corners that cannot be brushed can be cleaned with dental floss, toothbrushes or toothpicks. In addition, you should also go to the hospital regularly to clean the dental implants with special instruments, and if necessary, you can also ask a professional physician to dismantle and clean the mechanical parts to prevent the bacteria that breed from causing oral diseases and affecting the life of the dental implants.
