Zirconia Abutment for the Single Tooth Implant
Tony Aherne and Stuart Aherne present three case reports involving immediate implants with final zirconia abutments prepared extra-orally on fixture mounts and then attached to the implants.
Treatment protocols have changed and improved with the advent of new technology. One such material that is the subject of much interest is zirconium oxide (ZrO2). It is a highly biocompatible ceramic material providing fracture strength properties that allow application in all areas of the oral
cavity (Piconi C, Maccauro G, 1999; Kucey BK, Fraser DC, 2000). It also enables light transmission through the critical marginal area, preventing grey discolouration of the
surrounding tissue.
