STRAUMANN® PURE CERAMIC IMPLANTS:

 

THE IMPLANT AND ITS PROPERTIES

 

The Straumann® PURE Ceramic Implant has a monotype design based on features of the Straumann® Soft Tissue Level Standard Plus and Straumann® Bone Level Implants.


 It is available in endosteal diameters of ∅ 4.1 mm or 3.3 mm, with abutment heights of 4.0 mm or 5.5 mm. 

MORE THAN COMPLIANT TO INTERNATIONAL SAFETY STANDARDS

International standards specify the limits for radioactivity:

ISO 133565: specifies the properties of Y-TZP zirconia ceramics for implants and limits the mass activity to below 200 Bq/kg. The Y-TZP used for the Straumann® PURE Ceramic Implant shows a value of 20 – 50 Bq/kg, which is clearly below this benchmark.

The International Commission on Radiological Pro-tection (ICRP) specifies a dose limit of 1 mSv/year in addition to the natural exposure for the public6. The dose of one single Straumann® PURE Ceramic Implant is 0.01 mSv/year, which accounts for only 1 % of the ICRP limit.

CONCLUSION

The Straumann® PURE Ceramic Implant shows very low radioactivity levels which are insignificant compared to the natural yearly dose.

The values fulfil all safety standards. Therefore, it can be concluded that the very low amount of additional radio-activity bears no risk to the patient.
