About

With the development of Computer Aided Design and Computer Aided manufacturing (CAD / CAM) systems, all ceramic restorations have been used with high success rates during the past 30 years in order to eliminate the disadvantages of metal ceramic restorations. Based on these developments, in every passing days new ceramic materials has been added to dental market. The aim of the present study was evaluating clinical results of single-tooth ceramic crowns in the posterior region produced from three different monolithic ceramic materials.

Zirconium-reinforced glass ceramics (ZRGC)
Active Comparator group
Description:
12 posterior single tooth crowns made from monolithic zirconium-reinforced glass ceramics(ZRGC). Restorations were evaluated prosthetic and periodontal criteria at baseline, after 6 and 12 months. While prosthetic evaluation was performed according to Modified US Public Health Service criteria; probing depth(PD), clinical attachment level(CAL), gingival bleeding time index(GBTI), gingival(GI) and periodontal index(PI) were used in periodontal evaluation.
Treatment:
Other: Zirconium-reinforced glass ceramics(ZRGC),Lithium disilicate glass ceramics(LGC), Resin infiltrated glass ceramics(RIGC)
Lithium disilicate glass ceramics (LGC)
Active Comparator group
Description:
Group 2: 12 posterior single tooth crowns made from monolithic lithium disilicate glass ceramics(LGC). Restorations were evaluated prosthetic and periodontal criteria at baseline, after 6 and 12 months. While prosthetic evaluation was performed according to Modified US Public Health Service criteria; probing depth(PD), clinical attachment level(CAL), gingival bleeding time index(GBTI), gingival(GI) and periodontal index(PI) were used in periodontal evaluation.
Treatment:
Other: Zirconium-reinforced glass ceramics(ZRGC),Lithium disilicate glass ceramics(LGC), Resin infiltrated glass ceramics(RIGC)
Resin infiltrated glass ceramics (RIGC)
Active Comparator group
Description:
12 posterior single tooth crowns made from monolithic resin infiltrated glass ceramics(RIGC). Restorations were evaluated prosthetic and periodontal criteria at baseline, after 6 and 12 months. While prosthetic evaluation was performed according to Modified US Public Health Service criteria; probing depth(PD), clinical attachment level(CAL), gingival bleeding time index(GBTI), gingival(GI) and periodontal index(PI) were used in periodontal evaluation.
