The life expectancy of dental implants cannot be seen in specific values, but needs to be analyzed in combination with various situations. According to statistics, the general use of dental implants can reach 10 years, the failure rate of dental implants is lower than the rate of tooth loss of human own teeth, and it can be used for life with proper use and maintenance. It must be combined with the following factors: 1. The level of the doctor: if the doctor has accumulated more than 5 years of experience in dental implants, the success rate is greater than 90%. Successful dental implant technology will make dental implants last longer. 2. Use and maintenance status: If you do effective oral cleaning on time, dental implants will have a long life span, and if you clean your teeth regularly, you will have a longer life span than if you never clean your teeth. Dental implants that are properly maintained can last a lifetime. 3. The condition of the teeth themselves: the healthier the teeth around the implant, the longer the life expectancy, the fewer the missing teeth, the longer the life expectancy, and the more the surrounding alveolar bone shrinks, the shorter the life expectancy. Therefore, it is necessary for those who have dental implants to undergo a special cleaning of the implants and a routine cleaning of the surrounding natural teeth. Therefore, it is necessary to perform a special cleaning around the implant and a routine cleaning of the surrounding natural teeth to maintain the long-term stability of the implant.
