Background: Several grafting materials have been used for alveolar ridge augmentation. The literature lacks researches to compare CenoBone to other grafting materials. The aim of this study was to compare CenoBone/CenoMembrane complex to Bio-Oss/Bio-Gide complex in lateral alveolar bone augmentation in terms of radiographic, histologic, and histomorphometric parameters.

Materials and Methods: In this randomized controlled trial, ten patients who needed lateral ridge augmentation were selected and augmentations were done using either of CenoBone/ CenoMembrane or Bio-Oss/Bio-Gide complexes. In the re-entry surgery in 6 months following augmentation, core biopsies were taken and clinical, radiographic, histologic, and histomorphometric evaluations were performed.

Results: No statistically signifi cant difference was seen between groups except for the number of blood vessels and percentage of residual graft materials.

Conclusion: CenoBone seems to present a comparable lateral ridge augmentation to Bio-Oss in.

Key Words: Bio-Oss, CenoBone, lateral ridge augmentation
