At the beginning of treatment, all the dirt in the mouth will be removed as much as possible, including the patient’s full cooperation in oral hygiene cleaning, including toothbrush and dental floss, and the proper use of cleaning tools. After that, the whole mouth is scaled with ultrasonic wave, scraping of deep calculus in periodontal pockets and root leveling, removal of bad rejection, occlusal interference, etc. After scaling, use 8~lOml of rehabilitation solution, 3 times/day, rinse for 3 to 5 min, with the focus on nighttime rinse before bedtime. 1 month is a course of treatment, and repeat the above treatment after half a month of interval, after 3 consecutive courses to achieve healthy gingival papillae, no redness and swelling, no gingival atrophy, no bleeding from brushing, and no food embedment. Second, the surgical period The more serious affected parts, especially the periodontal pockets deeper, need to do periodontal flap surgery, in order to completely remove the calculus and diseased tissue. Periodontal surgery is a local and safe procedure that can be performed in a dental clinic. Under local anesthesia, the gums are slightly opened and the calculus and flesh tissues deep in the periodontium are completely removed. If there is bone loss, “periodontal regeneration film” and “artificial bone powder” can be placed to regenerate the damaged bone tissues and to actively rebuild the periodontal tissues. Third, maintenance period After going through the above treatment, it usually takes three months to six months, and after investing so much time and effort on it, it is extremely important to maintain the results. In addition to permanent and uninterrupted oral cleaning, you should follow the doctor’s instructions and return for regular checkups to fully grasp the periodontal and oral conditions.
