Rehabilitating the posterior maxilla with dental implants can be particularly challenging due to limited residual bone height and the close proximity of the maxillary sinus. Among the available techniques, the lateral window approach for direct sinus elevation remains the gold standard for achieving predictable vertical bone augmentation in these cases.

This lecture will offer a detailed exploration of the lateral window sinus lift procedure—covering essential surgical principles, required instruments, and a step-by-step technique. Special emphasis will be placed on anatomical considerations and strategies to manage intra-operative complications, including Schneiderian membrane perforations.

Participants will also learn structured clinical decision-making protocols to aid in case selection, choice of grafting materials, and optimal timing for implant placement. By integrating evidence-based guidelines with real-world clinical scenarios, this session aims to equip clinicians with the knowledge and confidence to perform this advanced procedure with precision, predictability, and safety—broadening treatment possibilities for patients with atrophic posterior maxillae.
