Wear at the titanium–titanium and the titanium–zirconia implant–abutment interface: A comparative in vitro study

Load to failure of different zirconia abutments for an internal hexagon implant

“…4 The findings of this pilot study were corroborated by a recent in vitro study comparing the maximum interface of implants connected to titanium and zirconium abutments. 11 After cyclic loading, SEM images of implant interface areas were made and analyzed with inspection software. The maximum wear for implants coupled with zirconia was 10.2 mm and 0.7 mm for those coupled with titanium abutments.…”

“…Zirkonyum yüksek esneme direnci (900-1200 MPa), sıkışma direnci (2000 MPa), ve kırılma dayanıklılığı (6 MPa.m 0.5 ), düşük pörözite, mükemmel biyouyum ve diş rengi ile uyumlu rengi nedeni ile tercih edilmektedir 39 . Zirkonyum abutmentların en önemli dezavantajı ise fonksiyon sırasında implant arayüzünde oluşan aşınmadır 40 . Zirkonyum, titanyumdan daha sert bir materyaldir.…”

“…Zirkonyum, titanyumdan daha sert bir materyaldir. Bu nedenle fonksiyon sırasında oluşan sürtünme esnasında zirkonyum abutment, implantın titanyum arayüzünde aşın-maya neden olmaktadır 40 . Stimmelmayr ve ark.…”

“…Stimmelmayr ve ark. 40 çalış-malarında tek parça zirkonyum abutmentın titanyum abutmenta göre implantın titanyum arayüzünde daha fazla hasara ve aşınmaya neden olduğunu göster-mişlerdir.…”

Titanium-Reinforced Zirconia Abutments Versus Pure Zirconia Abutments for Implant-Supported Single Tooth Restorations: A Systematic Review.

“…The similarity in physical properties of interfacing materials allows for higher mechanical stability and nullified wear potential. (9), (10), (13), (15), (16) These hybrid Ti-Zr abutments combine good esthetics of zirconia with mechanical advantage of all-titanium implant-abutment interface. (17), (18) Why it is important to do this review:-Up to date, there is no consensus on the ideal implant-abutment connection, and with the increased use of ceramic materials to meet the esthetic requirements of the dental patients, the ideal implant-abutment interface design in terms of abutment survival and patient satisfaction should be determined.…”
