Abstract :
Horizontal ridge deficiency often obstructs ideal implant placement and long-term success. This lecture presents an evidence-based approach to predictable horizontal alveolar ridge augmentation via guided bone regeneration (GBR). We begin by summarizing the biological principles underpinning successful horizontal bone regeneration — including space maintenance, angiogenesis, graft integration, and wound stability. Next, we critically review different graft materials, membrane types, and fixation techniques, and examine their performance in clinical studies and meta-analyses that report horizontal bone gains generally in the range of 3–5 mm. Based on these data, we distill practical guidelines and a decision-making framework to help clinicians choose the optimal GBR strategy according to defect type, grafting goals, and patient factors. Finally, through case-based examples (including CBCT-based planning), we demonstrate how to design a complete treatment plan:graft selection, membrane choice and fixation, soft-tissue management, and implant timing.The lecture aims to equip practitioners with the knowledge and tools to perform horizontal ridge augmentation with greater predictability.
Learning objectives :
- Describe the biological principles (e.g. space maintenance, angiogenesis, graft integration) necessary for horizontal bone regeneration.
- Distinguish among different graft materials, membranes, and fixation strategies in horizontal GBR, and select the appropriate combinations for given defect types.
- Interpret the scientific literature (e.g. meta-analyses, randomized trials) to summarize success rates, complications, and prognostic factors
- Devise a treatment plan for a horizontal ridge defect (with CBCT or case data) including grafting choice, membrane, fixation, and soft-tissue management
