Abstract

Privremeni nadomjestci danas predstavljaju nezaobilazan dio svake fiksnoprotetske rehabilitacije tijekom koje moraju ispuniti svoju protektivnu, profilaktičku i preventivnu ulogu te zadovoljiti mehaničke, biološke i estetske kriterije.
Privremene se krunice prema trajanju mogu podijeliti na kratkotrajne i dugotrajne, prema vrsti na konfekcijske i individualne te prema način izrade na one fabricirane direktnom, direktno- indirektnom te indirektnom tehnikom. Nadomjestci također mogu biti izrađeni i CAD/CAM (computer-aided design / computer-aided manufacturing) tehnologijom strojnim glodanjem iz polimernih blokova i tehnikom 3D printanja.
Materijali za izradu individualnih privremenih nadomjestaka tradicionalno se dijele u dvije skupine prema kemijskom sastavu. Kemijski polimerizirajući metakrilati nude dobra mehanička svojstva, no uz veći kapacitet polimerizacijske kontrakcije i estetsku upitnost. Suvremeniji, dualno ili svjetlosno polimerizirajući hibridni BIS – akrilni kompoziti estetskim svojstvima nadmašuju metakrilate, polimerizacijska kontrakcija je minimalna, jednostavni su za uporabu, a glavna im je mana viša cijena. Posebne vrste materijala upotrebljavaju se kod konfekcijskih nadomjestaka i CAD/CAM tehnike.
Gotovom privremenom nadomjesku potrebno je pažljivo obraditi rubove i ispolirati sve površine kako bi se smanjila mogućnost iritacije mekih tkiva te ograničilo nakupljanje plaka. Za cementiranje privremenog rada koriste se privremeni cementi nižih vrijednosti vezne čvrstoće.
S pacijentom je važno održavati komunikaciju kako bi privremeni nadomjestak postao pouzdano dijagnostičko sredstvo, a pacijent se osjećao slobodno upozoriti na neku od komplikacija koje bi mogle kompromitirati uspjeh konačnog rada.

Abstract (english)

The use of temporary restorations in contemporary prosthodontics has become an unavoidable part of every oral rehabilitation, as a part of which it has to fulfil its protective, prophylactic and preventive role. Mechanical, biological and aesthetic criteria have to be obtained.
Interim crowns can be divided based on the time of usage on short-term and long-term, by type on ready-made and individual and by fabrication on direct, indirect and indirect-direct. Provisional restorations can also be manufactured by CAD/CAM (computer-aided design / computer-aided manufacturing) technology out of polymer blocks or by 3D printing technique.
Materials used to make individual interim restorations are traditionally divided into two groups based on their basic chemistry: self-cured methacrylate which offer good fracture resistance but with a higher volumetric shrinkage and less aesthetic appeal, and more contemporary dual or light cured hybrid BIS – acril composites which are aesthetically more acceptable; with minimal polymerization shrinkage, but more expensive. Special types of materials are used for fabrication of ready-made interim crowns and in CAD/CAM technology.
Carefully finished and polished margins as well as all the surfaces of the provisional are especially important for preventing the irritation of soft tissues and accumulation of plaque. Cements with limited binding strength are used for cementation.
Communication with patients is the fundament of success since it ensures the reliability of using the provisional as a diagnostic tool and makes patients feel free to warn us on time in case of any complications.
