1, a pair of removable dentures should be made in advance for missing teeth, and it is best to wear 1 month or more, so that chewing and aesthetics will not be affected within a few months from the first-stage operation to the second-stage operation (before installing the implant denture);

2. If there is tooth extraction or gum surgery, you should wait for 3 months, and then consider tooth implantation after the bone defect is repaired and the quality and shape of alveolar bone are satisfactory according to X-ray;

3, do dental implant surgery, should ensure good health. Do general blood routine examination, patients with mild hypertension should return to normal blood pressure, and women should avoid menstrual period;

4. Keep your mouth clean before operation, clean your teeth in advance, and cure oral inflammation and diseases;

5. Implantation surgery is generally performed in outpatient operating room. After the operation, you can go home to rest or stay in hospital. You can take care of yourself during hospitalization and generally don't need company.

6. It is best to bring photos of previous dentures and photos before missing teeth for the reference of restorers, so that the implant dentures made in this way are more natural and realistic in tooth arrangement and color.

I would like to remind you that patients who want to implant teeth but suffer from periodontitis will worry that the unhealthy oral environment will affect the effect of dental implants. Is that really the case? Can periodontitis affect the effect of dental implant?

Artificial dental implants are made of pure titanium through precise computer design and implanted into gingival bone through surgery. After three or four months, when the artificial tooth root and gingival bone are tightly sealed, dentures are made on the artificial tooth root. Because the artificial root is deeply embedded in the bone, it can bear normal chewing force without the help of natural teeth, and its function and beauty are almost the same as those of natural teeth.

Before dental implantation, it is necessary to improve the treatment level of periodontal disease. If it is not solved, it is necessary to implant teeth artificially. At this time, there are still many bacteria in the mouth, which will increase the chance of surgical infection. If the periodontal tissue is not perfect, dental implants will only cause implant periodontitis, which will be more difficult to deal with in the future. So all periodontal diseases should be treated first.

If periodontitis is not completely cured, the root of dental implant is implanted by periosteum cutting. Once infected with periodontal disease, dental implant periodontitis will invade bone marrow and destroy tissues, accompanied by soft tissue hyperplasia, suppuration, bleeding, redness and pain. Once periodontal disease of dental implant occurs, the dental implant must be removed. Once implant periodontitis occurs, it will do great harm to implant teeth with pain and implant shaking, which may lead to implant failure.

Three factors affecting the preoperative effect of dental implantation

First, the bone compatibility of implant materials.

Dental implant is a kind of human implant surgery, and the compatibility of its materials with human body is particularly important. Unreasonable material selection may lead to implant failure, induce infection, alveolar bone inflammation and other oral diseases, and endanger oral health. In severe cases, it will even affect other normal tissues and functional health of the body.

Therefore, in order to ensure the safety and reliability of human body, generally speaking, pure titanium metal with high compatibility with human bones is used as the manufacturing material of dental implants. In addition, titanium has relatively good corrosion resistance, wear resistance and biocompatibility, and has high stability in vivo, no toxic or side effects, and will not cause harm to the body after implantation. However, if unqualified and inferior implant materials are used, it will lead to infection.

Second, the surgeon's technical proficiency and rich experience

Dental implant is a minimally invasive plastic and cosmetic technique. Whether the doctor's technical mastery is exquisite or not, and whether the clinical practice is rich or not, is related to the handling level of temporary events in the process of surgical implantation and the improvement of implantation effect. Once the implant doctor's technical operation is not enough, it will lead to incorrect treatment, and may lead to the outbreak of various adverse symptoms such as bleeding, numbness of the lower lip and wound cracking. In addition, experienced doctors can better deal with patient consultation, which has a great influence on treatment and nursing.

III. Disinfection Status of Planting Equipment and Instruments

Dental implant surgery is also a kind of surgical operation that needs to be carried out under aseptic conditions, and the disinfection status of related equipment and instruments is extremely important. Incomplete disinfection may induce a series of symptoms such as alveolar bone inflammation, which is directly related to the safety of surgery and the effect after implantation. Therefore, before dental implantation, all instruments and operating environment should be strictly disinfected to ensure sterility, eliminate cross-infection from the source and avoid innocent victims.
