Periodontal and peri-implant plastic surgeries have gained increasing prominence for addressing both esthetic and functional soft tissue deficiencies. These oral plastic procedures not only enhance esthetics but also play a pivotal role in enhancing the long-term stability of periodontal and peri-implant tissues. In this course, we will delve into the current state of knowledge surrounding periodontal and peri-implant soft tissue augmentation studies. We will outline the rationale behind these procedures and emphasize an evidence-based approach to prevent and manage periodontal and peri-implant soft tissue deformities effectively.
