Stoke-on-Trent (UK), 02 November 2009 – CERAM, a global expert in materials testing, analysis and consultancy announces that it offers a full suite of testing for Yttria-Stabilised Zirconia (YSZ), destined for surgical implants, as defined in ISO 13356 standards. These standards specify the characteristics of, and corresponding test methods for, YSZ and were recently updated in 2008 to provide clinicians with even greater confidence in the resilience of these materials for surgical implants, including restorative and prosthetic dentistry and hip- and knee-joint replacements.

There is a growing need for longer lasting YSZ ceramic implants as a result of the ageing population combined with the trend towards younger hip implant patients who tend to opt for ceramic-on-ceramic implants over other materials. Lifetimes of 30 years or more are the goal. It is important that sufficient research is done to demonstrate that these implants meet durability needs for longer term use.

“Research into maximising micro-structure homogeneity in sintered ceramic implants is important as there is no long term data on the performance of ceramic hip and other implants over time. As revisionary surgery can add a further 70 to 100% to the cost of the original operation, there is a need to produce implants that have certified durability,” commented Dr Phil Jackson, Business Development Manager, Medical and Healthcare, at CERAM. “I believe that the use of nanotechnology and novel shaping techniques will ultimately deliver the defect-free micro-structures needed to further retard hydrothermal ageing of YSZ. This will enhance the lifetime and reliability of implants – important factors when implants need to last longer to match increasing human longevity.”
