This evidence-based course integrates three core areas of modern dentistry: periodontal therapy, peri-implant disease management, and crestal bone preservation. Participants will explore diagnostic standards, classification systems, and treatment modalities for managing periodontal and peri-implant diseases. Emphasizing prevention, early detection, and both nonsurgical and surgical approaches, the course examines how implant design, placement depth, and soft tissue management impact long-term outcomes. Through case analysis and clinical protocols, attendees will gain practical strategies to preserve bone, enhance implant longevity, and deliver patient-centered care.
