BoneMaster®
BoneMaster® is the new coating technology platform of Biomet.
BoneMaster® is an advanced biomimetic coating technology with the biological benefits of hydroxyapatite and an enhanced needle-like nanostructure based on apatite crystallites found in bone. Through its combination of chemistry and surface topography BoneMaster® offers a number of unique clinical advantages.
Due to the positive interactions between BoneMaster® and Bone, the secondary fixation of the implant occurs more rapidly which improves the implant stability and thereby the longevity of the implant.
Enhanced implant stability
Due to its superior characteristics BoneMaster® produces a good and fast bony integration. Additionally BoneMaster® retains the underlying titanium macrostructures, such as PPS, due to its exceptional thickness of only 5μm. By so doing BoneMaster® allows a direct anchoring between the newly formed bone and the implant, which leads to an improved implant stability. The increased implant stability of BoneMaster® coated implants has been demonstrated in various animal models using push-out and pull-out tests.
Reduced fibrous growth
BoneMaster® demonstrates both the osteoconductivity of hydroxyapatite and the unique needle-like nanostructure that closely resembles the apatite crystals found in bone. Through these properties BoneMaster® accelerated the bony integration and in so doing reduced fibrous growth, as demonstrated in the figure below

Increased bone density
In a recent clinical study, BoneMaster® coated stems showed significantly greater bone density, compared to identical plasma-sprayed HA stems.
