Rethinking GBR Success: Managing Failures and Achieving Predictable Bone Regeneration

— Biological principles of bone regeneration
— Indications and objectives of GBR
— Factors influencing predictable regenerative outcomes
— Principles of wound healing and space maintenance
— Aetiology of GBR failures:
 

- Surgical factors: flap design, tension-free closure, membrane handling, and infection control
- Patient-related risk factors: systemic conditions, smoking, oral hygiene, and compliance
- Material-related factors: graft selection, membrane characteristics, stability, and fixation
- Biological and mechanical causes of regenerative failure.
 

— Classification and diagnosis of GBR complications:
 

- Early versus late complications
- Partial versus complete graft loss
- Soft tissue dehiscence and membrane exposure
- Clinical and radiographic assessment of compromised regenerative sites.
 

— Review of representative GBR failure cases
— Identification of surgical errors and contributing risk factors
— Clinical decision-making based on radiographic and intraoperative findings
— Management of failed GBR procedures; 
— Immediate versus delayed intervention strategies
— Management of membrane exposure and infection
— Secondary grafting techniques and site reconstruction
— Criteria for retreatment and achieving predictable outcomes
— Prevention and long-term success.
