This comprehensive course reviews critical surgical techniques in modern implant dentistry designed to optimize bone volume and ensure long-term treatment success. It covers the principles, clinical procedures, and outcomes of ridge split and expansion for widening narrow alveolar ridges with adequate height, minimizing the need for extensive grafting. Additionally, the course provides evidence-based criteria for extraction socket management, guiding clinicians on when to perform immediate implant placement, pursue socket preservation, or allow natural healing. Finally, advanced guided bone regeneration (GBR) techniques are highlighted, focusing specifically on rigid fixation procedures to prevent bone recession following augmentation.
