Haftung von Knochenzement auf keramischen Oberflächen – Deaktivierung der Oberfläche als wirksame Retentionsfläche für Knieendoprothesen durch die Adsorption von atmosphärischem Wasser

Abstract: Silicoating is effective in achieving high bond strength of bone cement on surfaces of oxide ceramics and can also stabilise the long term behaviour of the bond strength, provided the surface has been thermally treated prior to silicoating. Because of the proposed migration of the silicoating layer, micromotions and debonding should be widely reduced or even eliminated.

“…Undercuts generated is a highly efficient way to augment mechanical adhesion to a Co-Cr-Mo surface; however, this is not possible on a ceramic surface, due to the brittleness of ceramics. Lack of bone cement retention promotes micromotion of the prostheses which, in turn, predictably leads to early aseptic loosening ( 23 ).…”

“…Originating as a procedure from dental prosthetic research, the coating is applied to the prosthesis using physical vapour deposition (PVD) (PVD silicate layer) [33]. Through specific adhesion, the silicate layer protects the retention against hydrolytic degradation, i.e., debonding processes [34]. This is a multi-layer coating system which grips between the polymer chains of the bone cement and the superficial metal oxide layer of the titanium alloy.…”

“…Sie stellt ein Verfahren aus der zahnprothetischen Forschung dar und wird mittels physikalischer Gasphasenabscheidung (PVD-Silikatschicht, PVD: physical vapour deposition) auf die Prothese aufgebracht [33]. Durch spezifische Adhäsion wird die Retention durch die Silikatschicht gegen hydrolytische Degradation, also Debonding-Prozesse, geschützt [34]. Es handelt sich um ein Multilayer-Beschichtungs-System, das zwischen die Polymerketten des Knochenzements und die oberflächliche Metalloxidschicht der Titanlegierung greift.…”
