Comparison of two bone substitutes and collagen membranes in a one-stage procedure for horizontal bone augmentation: anorganic bovine bone (Bio-Oss) and collagen porcine membranes (Bio-Gide); (BB group) versus a synthetic resorbable bone graft substitute made of pure β-tricalcium phosphate (Ceros TCP) and porcine pericardium collagen membranes (Jason® membrane); (CJ group).
Twenty-five patients with 32 implants were allocated to the BB group and 25 patients with 29 implants to the CJ group.
Results / Conclusion:
No significant differences, except for radiographic bone loss, were observed in this randomised controlled trial comparing anorganic bovine bone with collagen porcine membranes versus synthetic resorbable bone made of pure β-tricalcium phosphate with pericardium collagen membranes for horizontal augmentation. The slight difference in radiographic peri-implant bone loss favoured the CJ group.
