Efficacy of porous bovine bone mineral in various types of osseous deficiencies: Clinical observations and literature review

Recent developments in osseous regenerative techniques have increased the d emand for bone-substitute grafting materials. Porous deproteinized bovine b one mineral (PBBM), a biocompatible xenograft, has been used in different o sseous deficiencies prior to or in conjunction with the placement of titani um implants. The different PBBM applications in fresh extraction sites, ana tomic defects, and subantral floor elevation techniques are described. The use of an occlusive barrier membrane to regenerate bone via guided tissue r egeneration principles was determined for each patient by clinical paramete rs. PBBM was well amalgamated and incorporated with the augmented hard tiss ue, but the transition between preexisting bone and the newly regenerated b one-like tissue was distinguishable by clinical examination even after 12 m onths. Grafted material was also identified using follow-up radiographs. In the presented cases, PBBM showed clinically satisfactory results as a bioc ompatible filler in bone augmentation procedures.
