The biggest advantage of dental implant technology is that the chewing function of people’s teeth is greatly improved after treatment, and the effect is more realistic. After the restoration of dental implants, good oral hygiene and health care habits are the guarantee to prolong the use of dental implants. After all, dental implants are not natural teeth. To ensure the longevity of dental implants, you should pay attention to daily maintenance. After the implant treatment is completed, you should pay attention to the following issues: 1. Eat a liquid or semi-liquid diet on the day of surgery, brush your teeth to avoid the surgical area within one week, pay attention to observation within two weeks, and contact your doctor in time if you find any abnormality. 2. Within three to six months after the removal of the stitches, do not make the artificial tooth root shake and chew hard with it, so as not to loosen the root and affect the newly formed bone and fibrous connective tissue around the root, thus affecting the implant effect, which is an extremely important issue to ensure the implant effect. Maintain good oral hygiene; regular review; generally 1, 3, 6, 12 months when the review. One year after the completion of the restoration, it can be reviewed once every six months. 3. The gingival penetration part of the implant forms an epithelial cuff with the gingival epithelium, which prevents various infections in the oral cavity from entering the implant-osteointegration interface, thus maintaining the long-term stability of the dental implant. The biologically damaging effect of bacteria, viruses, etc. on this cuff as well as the mechanically damaging effect on this cuff when the dental implant is subjected to forces can have a direct impact on the longevity of the dental implant. In this way, it is necessary to perform a special implant cleaning around the dental implant and a routine cleaning of the surrounding natural teeth. Use a soft-bristled toothbrush and clean the dental implants at least twice a day. After brushing, it is best to floss and then clean the adjacent spaces of the teeth. 4. After placing porcelain teeth, it is not advisable to chew anything too hard because there is no protective pressure receptor around the artificial tooth root and the root tissue is vulnerable to damage. After more than 40 years of development, oral implant technology has formed a complete theoretical system, which is widely used in the restoration of single tooth, multi-tooth and full mouth tooth loss, with a success rate of more than 97%. Dental implants are natural, beautiful and functional, and are now regarded as the preferred restoration method for tooth loss in developed countries.
