EnBIO launches OsteoZip surface for dental implants

Aug. 13, 2009
OsteoZip is designed to enhance the osteointegration and early bone fixation of dental implants into host bone tissue.

EnBIO has announced the launch of OsteoZip, a new hydroxyapatite surface for dental implants.

OsteoZip is designed to enhance the osteointegration and early bone fixation of dental implants into host bone tissue. OsteoZip is applied and enabled by EnBIO's CoBlast surface modification process.

The CoBlast process is noncomplex, room temperature, and requires no wet chemistry. This provides dental implant OEMs with a surface at a competitive cost.

The CoBlast process is a variation of grit blasting--a process in the medical device industry--and the CoBlast processing equipment is essentially a modified version of standard grit-blasting equipment.

New dental implant surfaces generally are measured on their performance against osteointegration, bone ongrowth, and long-term stability, and how they compare to untreated metal surfaces and to commercially available surface finishes.

EnBIO's in vitro and in vivo testing shows that, when compared to a number of other commercially available surfaces on dental implants (Roughened Surface, SBM – Soluble Blast Media, Plasma Sprayed HA, and Sintered Plasma Spray), OsteoZip provides:

* Improved osteointegration
* Earlier bone ongrowth
* Better long-term stability

The HA on the OsteoZip surface is ~100% crystalline (HA is not heated during the deposition process) and has a thin HA layer (~10µm) to help provide enhanced performance.

This thin layer also means that the HA will not shear or delaminate, counteracting the problem of traditional HA coatings (applied via plasma spraying). It is expected that this will also result in better long-term stability relative to traditional HA coatings.

EnBIO's business model is twofold. Fundamentally, the CoBlast technology will be licensed to OEMs. EnBIO will work with OEMs to set up and optimize the OsteoZip surface using modified grit-blasting equipment.

Alternatively, EnBIO can provide a coating service (via established implant coating partners) for prospective customers who do not wish to set up a CoBlast coating capability in their facility.

EnBIO has filed an OsteoZip master file with the FDA.
