Samples machined in PEEK-OPTIMA HA Enhanced

Technical summary

Overview of PEEK-OPTIMATM HA Enhanced

An objective reading of the properties, surface mechanism and evidence presented for PEEK with integrated hydroxyapatite.

Technical view

Implantable PEEK with osseointegration surface

The combination maintains the mechanical and image characteristics of PEEK-OPTIMA and adds HA crystals distributed by the matrix. As HA is not applied as coating, it remains available on the final surfaces produced during manufacturing.

Uncoated

HA is incorporated into the polymer, avoiding depending on a surface layer applied after manufacture.

modulus near the bone

The rigidity of the material is closer to that of the bone than that of metals traditionally employed.

radiolucency

It favors interface visualization and image monitoring, with less metal interference.

Surface with HA

The processing reveals hydroxyapatite crystals on the finished surfaces of the device.

91,3% fusion in 6 months in the mentioned observational record

96,8% satisfaction in 6 weeks informed in the registration

20 centers participating in the multicenter registry

How it works

Hydroxyapatite is a calcium phosphate mineral. In the material, its crystals are integrated into the volume of the PEEK and are exposed to the finished surface, seeking to favor direct contact with the bone.

What the evidence indicates

The aforementioned preclinical studies indicate greater bone apposition in sheep models. The clinical record of ACDF reports favorable evolution of fusion, pain and function, but its observational design does not allow attributing results only to the material.

Project Decision

The selection should consider anatomy, load, geometry, production process, finishing, sterilization, regulation and clinical protocol. The technical team can support this evaluation from the choice of the form of supply.
