Sometimes, due to injury or illness, the knee or hip joints have to be replaced by artificial orthopedics. These surgeries are expensive, painful and high risk.

A key aspect to obtain the best results is the longevity of the implants and a minimum generation of waste from them. We must work to achieve a useful and lasting life with the use of adequate coatings for surgical implants.

Porous, rough and plasma coating

It is obvious that no surgical patient and no doctor will want the joint replacement to wear out sooner than expected. But for these implants to last over time, they must be properly covered.

At Biovac we have different types of coatings for surgical implants, made under the highest existing security measures and under customer specifications. Our processes follow the procedures established by the GHTF guide.

In addition, the entire process is carried out in our facilities, so the traceability of the implant is guaranteed.

The types of coating that we carry out at Biovac are the following:

  • Porous coating with micro-spheres (Ti,Cr-Co, porous coating).
  • Porous coating with irregular particles (Ti, Cr-Co, porous coating).
  • Rough Titanium coating (Ti, plasma spray coating).
  • Hydroxyapatite coating (HA, plasma spray coating or porous coating).
  • Double layer plasma coating (HA + Ti, plasma spray coating).

In turn, these coatings can be classified as follows:

  1. Due to the applied technique: porous coating or plasma spray
  2. Due to the materials that make up said coating: cobalt/chrome, titanium, or Hydroxyapatite

Porous coating with microspheres or irregular particles ensures bone ingrowth through the porosity of the implant coating and in titanium plasma coating, the bone adapts to the roughness of its voids.


Porous coating

The porous coating process has been developed internally at Biovac and for more than 30 years. Here the objective has always been osseointegration and for this reason we opted for the porous coating technique, where we work manually and cover any geometry of the implant.

The microspheres can have different diameters and this positively affects any type of implant or surface.

These microspheres create a porous mesh that makes it easier for the bone to grow through its interstices and this makes it easier for the implant to attach to the bone naturally in the long term.

Plasma rough coating

We also carry out this type of coating internally and through thermal projection technology that consists of spraying small hot particles and adhering them to the surface.

Its use is very common in the medical-pharmaceutical sector where it is desired to coat a specific piece or part of the implant and promote osseointegration. It has many advantages to value.

At Biovac we perform this plasma coating with titanium, hydroxyapatite or both materials.
