Abstract: Aggressive periodontitis develops rapidly，frequently leading to tooth loosening，displacement，or even loss，which severely affects the oral health and functions of patients. Treatment goals of these patients encompass preserving remaining natural tooth，establishing stable periodontal health，restoring favorable occlusal contacts，and improving the chewing function. This article presented a case of generalized aggressive periodontitis with dentition defect，in which periodontal-implanting therapy was used to recover periodontal health and re-establish functional dentition consisting of natural tooth and implant prosthesis. And a regular follow-up protocol was implemented to ensure long-term stability. It is expected to provide experience for the multidisciplinary treatment and long-term maintenance of such cases.

Key words: aggressive periodontitis, dentition defect, multidisciplinary treatment, initial periodontal therapy, dental implantation
