Ridge Augmentation Using Titanium Mesh and Allogenic Bone Graft
Objectives: Titanium(Ti) mesh was presented as an alternative to a barrier membrane for guided bone regeneration(GBR). While there are many benefits when GBR is performed with Ti-mesh, the most significant benefit is great space maintenance for bone regeneration.
This study aims to clinically and radiographically evaluate the results of bone gain in various bone defects after GBR using Ti-mesh and allogenic bone graft to reconstruct edentulous ridges.
Methods: 24 patients were included in this study whose edentulous ridges were reconstructed with GBR using Ti-mesh. Alveolar reconstruction was performed on a total of 60 defect areas. Defects were classified into three type(Horizontal, vertical, combined) according to ‘Cologne Classification of Alveolar Ridge Defect’.
For ridge augmentation, mixed allograft material (cancellous FDBA 50%+ cortical FDBA 50% / Allo-Oss, CG Bio, Seoul, Korea) and Platelet rich fibrin(PRF) were mixed. Horizontal bone gain and shrinkage rate were evaluated at a distance 2mm(H1), 7mm(H2), and 12mm(H3) apical from the regenerated alveolar crest. Vertical bone gain and shrinkage rate were also evaluated at the long axis of the reconstructed alveolar crest(VC) and the area 2mm(VB) buccal and 2mm(VL) lingual from the axis.
Results: In horizontal defects(27 sites), average bone gain was 4.97(±2.01)mm at H1, 4.95(±2.24)mm at H2, and 1.83(±2.28) mm at H3. There were no significant differences in shrinkage rates. (P>0.05)
In vertical defects(14 sites), average bone gain was 7.52(±1.51) mm at VB, 7.97(±1.89)mm at VC, and 7.03(±1.45)mm at VL. There were no significant differences in shrinkage rates. (P>0.05).
In combined defects(19 sites), horizontal bone gain was 7.51(±2.11)mm at H1, 6.02(±2.77)mm at H2, and 2.72±(3.16)mm at H3 and vertical bone gain was 5.73(±3.04)mm at VC. Vertical shrinkage rate of allografts was statistically lower than horizontal shrinkage rate. (P<0.05)
Conclusions: GBR using allograft and Ti-mesh is a predictable procedure in the reconstruction of atrophic edentulous ridges. Favorable results were obtained in both vertical and horizontal ridge augmentation. Further clinical studies and long-term follow-up are indicated before definitive conclusions can be made.
