Next Generation of Ceramics.
BIOLOX® delta
BIOLOX® delta
The next generation of ceramics is available with XLE Vitamin E, our advance polyethylene material with superior oxidative resistance, low wear, and optimized mechanical strength.1-9 This material also provides a new ‘option’ for using a ceramic femoral head in a revision scenario with the BIOLOX®OPTION.
Science Behind the Material
Aluminum oxide matrix consisting of approximately 80% alumina, 17% zirconia and 3% strontium oxide.
Zirconia was added to increase the material strength and prevent the initiation and propagation of cracks.
An additional toughening mechanism is created with the addition of strontium oxide, which forms a platelet type crystal to dissipate energy by deflecting cracks.

BIOLOX® OPTION
The need for a low-wear ceramic bearing in revision arthroplasty was not available in the past. The OPTION is comprised of two components:
- BIOLOX®delta ceramic femoral head
- Adapter sleeve
The titanium adapters have an internal 12/14 taper that mates with the femoral stem while the OPTION heads have a taper designed to mate with the adapters.
