Abstract
Keramika ima bogatu povijest u dentalnoj medicini te je odigrala ključnu ulogu u osiguravanju visoko kvalitetnih nadomjestaka prirodnog izgleda. U ovom radu je prezentiran slučaj koji ilustrira protetsku rekonstrukciju zuba endokrunicom atipičnog oblika iz litij disilikatne staklokeramike. Litij disilikatna staklokeramika ima optimalnu estetiku i odlična mehanička svojstva. Može se prešati ili izraditi CAD/CAM tehnologijom. Kao kod svakog materijala, uspjeh nadomjestka iz litij disilikatne staklokeramike ovisi o pravilno postavljenoj indikaciji, pravilnoj preparaciji i laboratorijskoj izradi te o ispravnom postupku cementiranja. Čvrstoća nadomjestaka iz litij disilikatne keramike izrađena CAD/CAM tehnologijom je 360 MPa, a one izrađene prešanjem je 400 MPa. Nadalje, litij disilikatna staklokeramika pokazuje visoku rezistenciju na zamor, a trošenje nasuprotne cakline litij disilikatom u usporedbi s drugim keramikama pokazalo se jako niskim. Litij disilikatna keramika se također odlikuje visokom biokompatibilnošću. Dostupna je u četiri osnovne razine translucencije: visoka translucencija – HT (High Translucency), niska translucencija – LT (Low Translucency), srednji opacitet – MO (Medium Opacity), visoki opacitet – HO (High Opacity). Monolitna litij disilikatna staklokeramika omogućava izuzetnu čvrstoću i estetiku bez potrebe za površnim slojem keramike. Prešana litij disilikatna staklokeramika omogućava izradu tankih (no-prep) ljuskica. Zbog njezine povećane čvrstoće i niske viskoznosti tijekom prešanja omogućena je izrada tankih nadomjestaka debljine 0.3 mm.

Ceramics have a rich history in dentistry and have played the key role in ensuring high-quality, natural-looking restorations. Case report presents prosthetic tooth reconstruction with the atypical lithium disilicate glass ceramic endocrown. Lithium disilicate glass-ceramic has the optimum aesthetics and excellent mechanical properties. It can be traditionally pressed or processed via CAD/CAM technology. Like any restoration, the success of lithium disilicate glass-ceramic restorations depends on properly set indication, proper preparation and laboratory production and also correct cementation process. The strength of lithium disilicate restorations made via CAD/CAM technology is 360 MPa, and of those pressed is 400 MPa. Furthermore, lithium disilicate glass-ceramic exhibits high resistance to fatigue, also wear of opposing enamel, compared with other ceramics, is very low. Lithium disilicate ceramic also has high biocompatibility. It is available in four basic levels of translucency: high translucency (HT), low translucency (LT), medium opacity (MO), high opacity (HO). Monolithic lithium disilicate glass-ceramic provides exceptional strength and aesthetics without required superficial layer of ceramic. Pressed lithium disilicate glass-ceramic allows production of thin (no-prep) veneers. Due to its high strength and low viscosity during the pressing, it enables the production of restorations 0.3 mm thick.
