English abstract
Nowadays there exist different abutments from different companies that are compatible to a certain manufacturer implant. But no scientific evidence exists on whether the fit of the compatible abutments are comparable to that of the genuine abutments when connected to the genuine implants. God fitting of implant components is an essential factor to avoid microgap formation in implant-abutment interface due to microgaps lead to biological and biomechanical complications. The aim of this study was to compare interface in original abutment and copy compatible abutment connected to original implant. Material and Methods: Five original abutments and five compatible abutments were connected to the original implants. The complex were sectioned in the middle and thereafter analyzed in a light microscope and SEM by measuring contact length and interface thickness between the implant and abutment and also between the abutment and abutment screw. All data was analyzed with SPSS-program. Result: Compatible implant complex had about five times shorter contact surface between components and interface was thicker which gives less stability under clinical function. The analyze of screw-abutment interface showed morphologic differences with the inner surface of the abutment which could lead to screw deformation and even fracture. Conclusion: Using low-cost compatible abutments connected to original Astra implants could lead to significant fit discrepancy of the copy abutments and lower stress tolerance in the abutment screw.
Swedish abstract
I nuläget finns flertalet företag som tillverkar distanser som är kompatibla med originalimplantat. Det finns dock ingen evidens för att dessa distanser är likvärdiga med originaldistanser när de används på originalimplantat. God passform hos implantatkomponenter är en viktig faktor för att undvika biologiska och tekniska komplikationer. Syftet med den här studien var att jämföra passformen mellan originaldistans och originlimplantat med kompatibel kopiadistans och originalimplantat. Material och metod: Fem originaldistanser och fem kompatibla distanser skruvades till originalimplantat. Provkroppar bäddades in och delade på mitten för att sedan analyseras i ljusmikroskop och SEM. Där mättes kontaktytans längd och mellanrummet mellan implantat och distans och distans och distansskruv. All data analyserades i SPSS. Resultatet: Implantatkoplex med kopiadistans hade fem gånger kortare kontaktyta mellan komponenterna och mellanrummet var större, vilket ger en försämrad stabilitet under andvändning. Analysen av distansskruvens yta visade morfologiska skillnader mot den inre ytan av distansen vilket kan leda till deformation och/eller fraktur av skruven. Konklusion: Användning av lågpris kopiadistanser till Astra originalimplantat kan leda till signifikant avvikande passform hos distansen och en lägre tolerans för stress hos distansskruven.
