Abstract

This study aimed to evaluate vertical bone gain in the anterior edentulous mandible using the split cortical bone plate technique with two different graft and membrane combinations: autogenous particulate grafts with titanium-reinforced (Ti-PTFE) membrane (T1) and a mixture of autogenous and xenograft particulate grafts with collagen membrane (Bio-Gide) (T2). Twenty-two patients presenting with severe vertical alveolar ridge atrophy were randomly allocated into two equal groups, with eleven participants in each group. Cone Beam Computed Tomography (CBCT) was used to assess vertical bone gain and crestal bone loss at 6 months, 1 year, and 5 years post-grafting. Keratinized tissue width and peri-implant probing depth were also measured at the same intervals to evaluate long-term soft tissue stability and peri-implant health. While both groups demonstrated comparable vertical bone gain, the T1 group exhibited better maintenance of keratinized gingiva.It reduced crestal bone loss over time, suggesting the clinical utility of non-resorbable membranes in enhancing soft and hard tissue outcomes in complex augmentation cases.
