Background: Increasing complexity in bone defects and bone augmentation procedures poses significant challenges in properly handling and stabilizing bone grafts, especially within the Split Bone Block Technique (SBBT). Integrating digital tools and techniques has significantly advanced bone regeneration and augmentation procedures, offering new possibilities to address these challenges effectively. This study aims to present a case series using a method for transporting cortical bone blocks, including surgical and post-surgical complications, and bone gain at re-entry. Methods: This case series technical report introduces a transporter guide designed to facilitate the precise placement of cortical bone plates and improve surgical outcomes. Six cases were evaluated to assess graft stability, complications and post-surgical bone augmentation. Computer-aided design (CAD) and computer-aided manufacturing through 3D printing were utilized to develop surgical guides for bone harvesting, transporter guides, and bio-models, optimizing the adaptation and fixation of cortical plates. Results: Postoperative cone-beam computed tomography (CBCT) scans demonstrated minimal discrepancies between planned and achieved outcomes, with the mesial region showing higher variation than the distal area. The transporter guide streamlined the surgical workflow and reduced intraoperative errors. Conclusion: These findings suggest that the transporter guide facilitates safer, more predictable outcomes in the Split Bone Block Technique (SBBT) by reducing surgical complexity and improving the precision of graft positioning and stabilization.
