Aim The objective of this report was to present histological characteristics and gene
expression profile of newly formed bone following horizontal augmentation of the atrophic
anterior maxilla using recombinant human bone morphogenetic protein‐2 in an absorbable
collagen sponge carrier (rh BMP‐2/ACS) versus an autogenous bone graft (ABG). Methods
Bone core biopsies from 24 subjects participating in a randomized clinical trial were
obtained at dental implant placement, 6 months following alveolar ridge augmentation using …
