RESUMO
According to needs of clinical diagnosis and treatment of periodontal disease in China, the Chinese Stomatological Association initiated the workshop of consensus of Chinese experts on treatment of severe periodontitis by the specialized committee expert group. In February 2017, the first part of the consensus was released [Chin J Stomatol, 2017, 52(2): 67-71]. The present report is the second part of the consensus, regarding the surgical treatment of severe periodontitis. The group believes that after initial treatment and reevaluation, some patients with severe periodontitis, can be considered to be performed with surgical treatment. When clinicians choose surgical treatment, the design of surgical methods should be guided by the objective of the operation. Therefore, in this consensus, Chinese experts put forward the objectives of surigical treatment into two kinds of objective, periodontal debridement and augmentation of periodontal tissue.
