This randomized controlled trial evaluates the clinical effectiveness and surgical accuracy of a computer-guided versus a conventional free-hand approach for horizontal ridge augmentation in the anterior mandible using the autogenous cortical shell technique.
Participants presenting with horizontal alveolar bone deficiency in the anterior mandible are randomly assigned to one of two groups:
Study Group: A fully digital workflow is employed, including CBCT-based virtual planning and the use of 3D-printed, patient-specific stereolithographic guides for both bone harvesting and graft placement.
Control Group: The traditional free-hand technique is used without computer-guided assistance.
The study is designed to assess whether the digital, guided approach enhances horizontal bone gain, optimizes graft placement accuracy, reduces operative time, and lowers complication rates compared to the free-hand protocol.
The intervention involves preoperative 3D planning, surgical guide fabrication, and intraoperative bone harvesting and grafting. Both groups receive autogenous cortical bone blocks harvested from the mandibular symphysis and secured at the recipient site with mini screws. Bone particulate (autogenous + xenograft, 1:1 ratio) is used to augment volume.
Primary outcome is the amount of horizontal bone gain measured via CBCT superimposition at baseline and 6 months postoperatively. Secondary outcomes include surgical time, accuracy of graft placement, and incidence of postoperative complications such as pain, swelling, infection, dehiscence, or graft exposure.
This single-center, single-blinded equivalence trial uses a 1:1 randomization ratio. Ethical approval has been obtained, and participants provide informed consent prior to enrollment. The results are expected to inform surgical best practices and improve the predictability of mandibular ridge augmentation procedures.This randomized controlled trial evaluates the clinical effectiveness and surgical accuracy of a computer-guided versus a conventional free-hand approach for horizontal ridge augmentation in the anterior mandible using the autogenous cortical shell technique.
