There was no evidence for the superiority of a given biomaterial over the others in terms of new bone formation. While calcium sulphate and beta-tricalcium phosphate resorbed faster than other biomaterials, xenografts showed a lower resorption rate than allografts. Comparative studies suggested that bovine bone was related to a lower proportion of new bone volume compared to sites left to heal spontaneously, while porcine bone and magnesium-enriched hydroxyapatite were related to higher new bone volume. Allograft was not related to higher new bone volume than sites healed without any biomaterial.
