Fracture strength of zirconia reconstructions

Fracture strength of zirconia reconstructions tested

  Zirconia is a popular option for dental implants due to its biocompatibility and its favourable aesthetic appearance. Increasing the connector area can help strengthen zirconia reconstructions, but this is not always possible in cases involving reduced vertical dimension. A recent study from Turkey compared the fractured strength of implant-supported cantilevered zirconia and metal frameworks.

The study involved 60 cantilevered implant-supported three-unit frameworks. These were divided into three groups: titanium abutment-zirconia, zirconia abutment-zirconia and titanium abutment-metal frameworks. Samples from each group were then divided even further by connector area size, either 9 or 15mm2. The cantilevered frameworks were all cemented using zinc-phosphate cement and loaded in a universal testing machine until fracture or decementation occurred.

The results indicated that the abutment material did not have a statistically significant impact on fracture strength, and that a connector surface area of 15mm2 in a zirconia superstructure with cantilever design had a reasonable fracture strength. It was also observed that increasing the connector surface area from 9 to 15mm2 improved fracture strength.

This study was presented as an e-poster at the 2018 EAO Congress.
