Resumen:
Un instituto de investigación esloveno ha desarrollado un proceso de revestimiento de implantes óseos de titanio o aleación de titanio con capa protectora y bioactiva que también puede conferir propiedades antibacterianas. El polvo tiene una superficie altamente específica y, por lo tanto, es muy soluble en líquidos. Este revestimiento se utiliza especialmente en implantes dentales. El revestimiento de óxido cristalino obtenido se fija firmemente en el sustrato, ofrece propiedades superficiales más favorables que las soluciones más recientes porque es hidrofílico, fomenta la formación de hidroxiapatita y la adhesión celular y evita la liberación de iones metálicos en los tejidos circundantes. El instituto busca socios industriales interesados en establecer acuerdos de cooperación técnica y licencia.

Tittle:
Bioactive and antibacterial coating for dental implants
Summary:
Slovenian research institute has developed a process for coating titanium or any titanium-based alloy bone implants with a protective and bioactive coating that can be also produced in a form with antibacterial properties. The powder itself has high specific surface area and is therefore highly soluble in liquid media. The coating is useful especially for dental implants. The institute is looking for industrial partners interested in technical cooperation- and license agreements.
Description:
A group of Slovenian researchers has developed a new bioactive and antibacterial coating for dental implants.

The low-temperature process for coating of titanium or titanium-based alloy with the coating is simple and can be performed in a single step. The formed crystalline oxide coating is strongly attached to the substrate, provides more favourable surface properties to the implant than the state-of-art as it is hydrophilic, promotes hydroxyapatite formation and cell attachment and it hinders release of alloying metal ions into the surrounding tissue. In addition, it may acquire antibacterial effect.

The coating can be used for any kind of Ti or Ti alloy implants, especially for dental implants to stimulate bone ingrowth and to improve implants´ longer-term behaviour.

The institute is looking for industrial partners interested in further development under the technical cooperation agreement and those interested in in-licensing of the bioactive antibacterial coatings for dental implants.
Advantages and Innovations:
The problems and deficiencies of implants that are currently in use are:
· Metals and therefore metal implants have hydrophobic surface which is not favourable for cells attached, in particular in the case of the rough or porous surface
· Metal ions are leaching from the implant into the body
· Titanium metal and Ti-alloys are not bioactive

The advantages of the offered new bioactive multifunctional coating material are:
- Coated metal implants are hydrophilic, thus providing more favourable surface for cells
- Its bioactive properties accelerate bone formation
- Leaching of harmful metal ions is reduced
- Antibacterial properties lower the probability of infection
Stage of Development:
