Surgeons all over the world put their faith in our pink-colored BIOLOX®delta ceramic. The very color gives surgeons the certainty that they’re using implants of the highest quality and reliability for their patients – from CeramTec. BIOLOX®delta is the only ceramic with 11 years of successful clinical experience – with more than five million implanted components.
BIOLOX®delta is the newest material in the BIOLOX® family. It is a mixed oxide ceramic with increased fracture strength, excellent wear properties and unlimited biocompatibility. Since its launch 3.8 million BIOLOX®delta ball heads and over over 1.5 million inserts (as of end of November 2014) have been implanted worldwide.
The main difference between BIOLOX®forte and BIOLOX®delta is BIOLOX®delta’s greater strength. However, the reliability of a ceramic implant depends on the actual loads it is subjected to, which are greatly influenced by the geometry, the design of the entire implant system, the surgical technique used and the post-operative behavior of the patient.
BIOLOX®delta was developed to open up a broader range of clinical uses including those which were not possible using BIOLOX®forte.
The first toughening mechanism is the introduction of yttria-stabilized tetragonal zirconia particles (Y-TZP) in a stable alumina matrix. These Y-TZP particles are spatially separated from each other in order to reduce the likelihood of structural transformation as well as to prevent the initiation and propagation of cracks.
The dispersion of fine particles in the matrix also improves the fracture strength and toughness of BIOLOX®delta components as shown in Fig. 1. This mechanism functions like the airbag in your car.
The second reinforcement mechanism is achieved by adding an oxide which forms platelet-like crystals. These platelets dissipate energy by deflecting cracks, thereby increasing the strength and toughness of BIOLOX®delta.
