Orchid's Coating Options

Hydroxylapatite (HA)

Optimized for osteoconductivity promoting bone growth

The same mineral found in bone may be applied directly onto multiple substrates or porous surfaces. Orchid’s HA coating has superior attachment strength to resist sheer forces and high
crystallinity to optimize resorbtion rate

Asymmatrix®

Optimized for initial fixation and stability achieved through the high coefficient of friction

Porous coating with extremely rough surface, only to be applied to similar materials (available in CoCr or Ti)

Learn More

Titanium Plasma Spray (TPS)

Optimized for initial bond strength

Commercially-pure and bioinert titanium porous coating that can be applied to dissimilar materials (ex: CoCr)

Learn More

Fortify™

Optimized for high porosity and bond strength applied to knee implant components

Commercially-pure and bioinert titanium porous coating that can be applied to dissimilar materials (ex: CoCr).

Spherical Bead

Optimized for applications requiring reduced resistance to implantation

Sintered bead coating, only to be applied to similar materials (available in CoCr or Ti)

Thin Titanium Plasma Spray

Optimized for interconnected porosity for titanium and PEEK spinal implants

Commercially-pure and bioinert titanium porous coating that can be applied to dissimilar materials (ex: Ti, PEEK)

Optimize Bone In-Growth Performance

Mechanical requirements of a hip implant are not the same as a knee or shoulder implant. Understanding the anatomical performance requirements and the ability to optimize the coating design will change an implant from “meeting” the requirements to “best in class” performance at the time of surgery and throughout the critical healing time period.

Orchid’s PhD level coating scientists have optimized our processes to tailor the performance of a coating to the specific mechanical properties of the implant.

Consult with us to optimize your coating performance for the specific implant application.
