Alveolar ridge augmentation with β-tricalcium phosphate (β-TCP) granules,calcium phosphate cement (CPC) powder and web form of titanium fibers (TW) addedto Platelet-Rich-Plasma (PRP) was histologically observed for 5 months by theexperiments using the maxilla of rabbits. As a result, TW was thus found to promotethe rapid bone development within a period of less than 5 months, because TW had anappropriate gap between the titanium fibers for new bone progression. However,titanium fibers remained intact within the maxilla. The CPC powder was transformedinto dense cement and also remained intact in the bone. These residual materialsmust be obstacles to perform the placement of dental implants.On the other hand, β-TCP granulations were gradually replaced by the new bone,but this process took about 5 months to be completed.Consequently, for an ideal alveolar bone substitute, there needs to be a suitable gapformation within the substitute, such as TW, and properties of total bone replacement,such as that seen in β-TCP granules.
