Flap Passivity: The Most Underestimated Cause of Graft Loss

Flap tension is one of the most underestimated causes of bone graft failure in implant dentistry. In this video, we break down the true biology of flap passivity, why tension leads to ischemia, membrane exposure, inflammation, and infection—and why eliminating tension alone is not enough. You’ll learn: • Why flap tension compromises blood supply and angiogenesis • How wound instability and micromotion damage newly formed blood vessels • The critical difference between passivity and mobility • Why “tension-free closure” can still fail • How to achieve passive closure with controlled stability This video is for implant dentists, oral surgeons, periodontists, and clinicians performing bone grafting, GBR, ridge augmentation, and immediate implant procedures who want predictable, biology-driven outcomes. If you’re an implant dentist who wants biology-driven, complication-proof surgery, subscribe. Every week we break down one clinical problem you’ve already seen in your practice.
