GBR Using i-Gen: A Retreatment Case of a Failed Implant

Anterior maxillary vertical GBR remains one of the most technique-sensitive procedures in implant dentistry, where both regenerative stability and esthetic outcomes must be carefully balanced. This lecture presents four biologically and surgically critical factors that influence the predictability of vertical bone regeneration in the esthetic zone. Through a step-by-step clinical case demonstration, participants will explore membrane selection based on defect morphology, flap management for tension-free closure, membrane stabilization concepts, and bilayer wound closure techniques. Emphasis is placed on evidence-based surgical decision-making to minimize complications and enhance long-term regenerative success. 

This lecture presents a new clinical approach to challenging anterior implant cases with severe bone loss. It focuses on the limitations of conventional GBR-based treatment and introduces the concept of achieving implant stability through basal bone fixation. The lecture also explains the design characteristics of the ARi implant, including implant length and cuff selection, and how these features can be applied in compromised anterior situations. Through clinical cases, participants can follow the treatment process from implant placement to final prosthetic restoration and understand how this approach may be considered in cases involving long-term edentulism, severe periodontal disease, or peri-implantitis.
