Abstract: The education of periodontal refresher doctors is an indispensable part of the education system of periodontology，which is of great significance to solve the imbalance between periodontists and periodontal patients in China. Based on the experience of more than 30 years of periodontal education in Peking University School of Stomatology，the teaching model of phased ability improvement for periodontal refresher doctors was summarized and explored according to the professional characteristics of periodontal therapy in this paper. In the model，the one-year education for periodontal refresher doctors was divided into four stages with three months as one stage. Stage 1 is to master periodontal theoretical knowledge and to preliminarily grasp initial periodontal therapy. Stage 2 is to strengthen and standardize periodontal theoretical knowledge and to re-evaluate the initial periodontal therapy. Stage 3 is to make multidisciplinary treatment design for complex patients and to preliminarily grasp periodontal surgery. Stage 4 is to cultivate the periodontal thinking of clinical diagnosis and treatment and to improve the ability on characteristic periodontal surgery. By designing a series of operable and quantifiable assessment standards，the training content of each stage can be implemented. It is expected that the popularization of this teaching model can promote the development of periodontal education in China.
