a histologic, histomorphometric, and radiographic comparison between two complexes of cenoboen/cenomembrane and bio-oss/ bio-gide in lateral ridge augmentation: a clinical trial

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
