According to the 2024 systematic review “Tunnel Technique in Bone Augmentation Procedures for Dental Implant Rehabilitation”, this approach has shown promising outcomes across a variety of grafting modalities, including xenografts, allografts, autogenous blocks, and titanium meshes.
A detailed examination of the 18 studies included in the review demonstrates that the tunnel technique is most frequently applied for horizontal ridge augmentation and for defect coverage requiring flap preservation.
Reported outcomes indicate consistent bone-gain measurements, high implant survival rates, and favorable esthetic integration—although methodological heterogeneity and limited long-term data highlight the need for more robust clinical trials.
Importantly, the review underscores that the technique’s success relies on careful soft-tissue management, surgeon experience, and precise case selection, especially in thin biotypes or extensive horizontal defects.
For clinicians focusing on minimally invasive regenerative approaches, this systematic review offers current evidence, clinical considerations, and guidance on integrating the tunnel technique into implant-related bone augmentation protocols.
