Abstract Gradivni materijali u implantoprotetici skupina su dentalnih materijala koji se koriste u implantoprotetskoj nadoknadi i rehabilitaciji bezubih prostora. Na temelju kemijskog sastava i strukture, materijale u dentalnoj implantologiji dijelimo na metale, keramike, polimere i kompozite. Materijale u implantoprotetici odlikuju njihova specifična fizikalna, kemijska, mehanička i svojstva biokompatibilnosti, a ovisno o protetskoj funkciji dijelimo ih na materijale za izradu implantata, implantatnih nadogradnji i protetskih nadomjestaka. Svi gradivni materijali moraju imati zadovoljavajuća fizikalna i biomehanička svojstva kako bi se
osigurala funkcijska trajnost. Materijali za izradu implantata osim izvrsnih biomehaničkih moraju imati i svojstva biokompatibilnosti u koštanom tkivu i sposobnost oseointegracije. Titanij i njegove slitine zlatni su standard za izradu implantata, a implantati na bazi cirkonijoksidnih keramika nova su alternativa u strogo indiciranim estetski zahtjevnim slučajevima. Za izradu implantatnih nadogradnji ključni postaju problemi estetike i odnos mekih tkiva s materijalima. Najčešće se i u njihovoj izradi koriste titanij i njegove slitine, ali cirkonij-oksidne keramike pokazuju izuzetnu biokompatibilnost i estetiku te su sve zastupljenije kao materijal izbora. Za izradu fiksno-protetskog nadomjestka i dalje se najčešće koristi metal-keramička krunica zbog svojeg omjera cijene, kvalitete i estetike, ali sve se češće zbog zahtjeva visoke estetike odabiru potpuno-keramički sustavi kao materijal izbora za nadomjestke u implantoprotetskoj terapiji.
Abstract (english) Constituent materials in implant prosthodontics are part of the group of dental materials used in implant prosthetic restoration and rehabilitation of edentulous spaces. Based on their chemical composition and structure, materials in dental implantology are divided into metals, ceramics, polymers and composites. Materials in implant prosthodontics are characterized by their specific physical, chemical and mechanical properties and their biocompatibility. Depending on their prosthodontic function, they are divided into constituent materials for implants, implant restorations and fixed prosthodontic materials. All constituent elements must have satisfactory physical and biomechanical properties to ensure functional durability. In addition to excellent biomechanical properties, constituent materials for dental implants must also be biocompatible with bone tissue, to ensure their ability of osseointegration. Titanium and its alloys are the gold standard for implant fabrication, whereas zirconium oxide based implants are the new alternative in strictly indicated, aesthetically demanding cases. Aesthetics and the compatibility of the materials with soft tissues play the key role in the selection of
constituent materials for implant abutments. Titanium and its alloys are most often used in their production, but zirconium oxide ceramics also show exceptional biocompatibility and aesthetics, thus becoming increasingly represented as the material of choice. Due to their price to performance and aesthetics ratio, metal-ceramic crowns are still the construction materials most commonly used in implant-supported crowns and bridges. However, due to very high aesthetic demands, all-ceramic systems are becoming the primary material of choice for fixed dental prosthesis.
