Abstract: Objective: To sum up the clinical experience of application of EB composite resin periodontal splint in treatment of the chronic pariodontitis. Methods: The stainless steel wire, the steel rectifying wire, the dental arc and composite resin combined with the periodontal splint were used to fix the loose teeth of 27 patients. One month after fixation with EB composite resin periodontal splint, the patients were followed up. Then, patients would be followed once every 3 months to a half year, in order to observe the clinical symptom, the loose degree of tooth, the periodontal bag situation and the function of chewing. At one time, X-ray was taken to observe alveolar bone situation and judge the result. Results: The patients were followed up for 3 to 5 years, 6 cases were good, 4 cases were improved. The effective rate amounted to 88.9%. Conclusions: The loose teeth are linked into a whole unit by the method, stabilizing loose teeth and stress, enhancing the chew function and efficiently controlling the chronic pariodontitis development.
