Evaluating Techniques for Vertical Ridge Augmentation via Comparative Study of Clinical Outcomes: A Systematic Review.

ABSTRACT: Background/Objectives: Vertical ridge augmentation (VRA) is often necessary in severe bone atrophy, yet the most predictable approach remains unclear. This systematic review compared Guided Bone Regeneration (GBR) and the Shell Technique (ST) for vertical bone gain (VBG), bone quality, complications, patient-reported outcomes (PROMs), and implant survival. Methods: Following PRISMA 2020 and PROSPERO registration (CRD420251128502), PubMed and Scopus databases were searched. Adults requiring VRA before implants were included. Interventions were GBR using titanium-reinforced dense PTFE (Polytetrafluoroethylene) or collagen membranes and ST using autogenous or allogeneic cortical plates. Results: Both techniques achieved clinically meaningful vertical augmentation. Median
