B. & B. Dental S.r.l. are among the few companies in Italy that use technological high-level decontamination procedures. The cleaning of equipment surfaces is a complex task. Even using very pure cleaning solvents can still leave surface traces. It can happen that the few existing impurities or the solvent molecules themselves combine with the materials of an implant surface, especially in the case of reactive materials like metals. The ideal cleaning tool should be unable to react chemically with the material of the device and at the same time be very effective for removing contaminants. Argon plasma is the ideal material for this.
DOUBLE ACID TREATMENT
B. & B. Dental have developed an exclusive BioActive treatment with the support of international researchers with extensive experience in surface treatment processes. It guarantees an implant surface with micro-controlled roughness.
This is achieved in a double acidification treatment, called DAE (Double Acid Etching), which prevents the formation of surface oxide on titanium, as well as cleaning even the internal part of threads.
BioActive treatment forms by subtraction a micro-controlled surface roughness which helps osteoblasts first to anchor on a cellular level and then to integrate into bone tissue, thus shortening osseointegration times. Crucially, all the processes are carried out with machines that guarantee both surface homogeneity and long-term duration of specific implant characteristics. In addition, all decontamination processes and surface treatments are conducted under cleanroom conditions.
Argon plasma treatment
Argon plasma is an ideal cleaning tool that does not react chemically with the material of a device and at the same time is very efficient for removing all possible contaminants on an implant surface. The Argon gas is used inside a reactor, housed in a class 10000 clean room, ensuring the absence of all environmental contamination. It is transformed into a plasma comprising ions of heavy gases, which are bombarded onto the implant surface with the cleaning action deriving from the impact energy of these particles against any organic contaminants.
This means that the surface never comes into contact with solvents.
The final check for the effectiveness of the process is performed using sophisticated, dedicated analysis techniques. Each batch of implant screws is subjected to x-ray photoelectron spectroscopy (XPS or ESCA), a widely-used analysis technique for rough surfaces composed of 95% titanium. This analysis provides information on the qualitative and quantitative chemical composition of the first nanometers of the material, which represents the layer that come into most direct contact with bone tissue.
