Patient: Description (onset time, main symptoms, hospital, etc.): Female, 34 years old, with several years of periodontal disease, lost one of the lower incisors, gum recession is very strong Did 2 scaling, a scraping, no effect Can see you, planting a tooth is lost one planting, or to pull all together, if you can plant, I want to know the specific steps and time, because I am still working in the field. Thank you, please reply. Sun Weilian, Department of Stomatology, The Second Affiliated Hospital of Zhejiang University School of Medicine: Hello! You are only 34 years old, if you lost your incisors because of periodontitis, you may have “aggressive periodontitis”. I suggest that you come to the hospital and let me take a look at your teeth to confirm the diagnosis and then make a general treatment plan. It is not a matter of losing one tooth and planting another. If the periodontitis is not controlled, you cannot get a dental implant. Think about it, your own teeth won’t grow securely, let alone the implants. The prerequisites for dental implants are: no periodontitis, or periodontitis has been controlled and stabilized; diabetes is controlled and stabilized; smokers try to quit smoking, etc. Otherwise, the long-term success rate of dental implants will be reduced. Dental aggressive periodontitis, with early onset and rapid progress, has a certain family aggregation, so it is more important to detect, diagnose and treat early. I wish you a healthy periodontal as soon as possible!
