RBM Surface

What is RBM? RBM, or resorbable blast media, is a surface treatment designed to roughen the surface of an implant without leaving the residual embedded blast particles or debris in the treated substrate. To achieve the desired roughening, a biocompatible material (hydroxyapatite and tricalcium phosphate) with a suitable hardened particle size is used and then subsequently dissolved from the surface with a defined passivation treatment. The result is a rougher surface than the traditional acid etch treatments, providing a greater surface area for osseointegration. Since ACE Infinity’s roughening process does not involve acid etching, the RBM implant surface is, by definition, free from acid etching residues. It is also not susceptible to titanium grain boundary degradation that can occur during aggressive acid etching procedures. ACE Infinity’s RBM implant surface has been in clinical use throughout the world since 1997 and has achieved a high level of clinical acceptance and success.
