“…The selection process resulted in the final sample of 14 journal articles. 5,11,16,18,24,33,34,36,[55][56][57][58]66,67 In total, 9 articles were identified related to all-ceramic single crowns, 3 of which were on anterior and 6 on posterior crowns, and 5 articles on 3-unit FDPs all of which were on posterior FDPs. In the selected 14 articles, a total of 43 experimental subgroups were identified where fracture strength results were reported in N. After data analysis, 50 articles were excluded, mainly due to lack of initial fracture load, [1][2][3]8,10,12,13,15,26,29,30,32,35,37,[41][42][43][45][46][47][49][50][51][52][53] final fracture load, 2,6,9,10,14,15,19,20,…”

“…In another study, the fracture strength of YSZ-FDPs was reported to be over 2000 N under static loading [ 25 ]. Eroğlu et al [ 26 ] studied the fatigue behavior of zirconia-ceramic and reported a fracture strength of 2333 N for three-unit FPDs. Each specimen was subjected to 100,000 chewing cycles at a 50 N load and a 0.5 Hz frequency on the pontic with a 16 mm 2 connector size.…”

“…The high fracture strength of yttria-stabilized zirconia (YSZ) is attributed to the physical properties of partially stabilized zirconia. In previous studies, the fracture strength of YSZ was reported to vary from 900 N [ 24 ] to 2000 N under static loading [ 25 , 26 ].…”

BackgroundThe purpose of this study is to evaluate the wear and fracture strength of crowns and three-unit partial fixed dental prosthesis (FDP) fabricated using by Bruxzir and Incoris TZI as recently introduced monolithic zirconia materials.MethodsA total of sixteen crowns and sixteen three-unit FDPs were fabricated using Bruxzir and Incoris TZI (n = 8). All specimens were subjected to a 2-body wear test in a dual axis chewing simulator for 1,200,000 loading cycles against steatite antagonist balls. The fracture strength and volumetric loss were recorded. The obtained data were statistically analyzed by 2-way ANOVA testing (α = 0.05).ResultsThe mean volumetric loss of the crowns was higher than that of the three-unit FDPs (p < 0.05). Of the two monolithic systems, Incoris TZI exhibited more wear than Bruxzir. The fracture strengths of Bruxzir crowns and FDPs were found to be higher than those of the crowns and FDPs fabricated with Incoris TZI (p < 0.05).ConclusionIn in vitro test conditions, Bruxzir and Incoris TZI monolithic zirconia systems are fracture-resistant for the crown and FDP application against physiologic chewing forces owing to dynamic aging. Among newly developed monolithic zirconia materials, Bruxzir is found to be more resistant to fracture compared to the Incoris TZI.

“…The teeth were prepared by using a paralellometer (Paraskop, Hebst GmbH & Co., Bremen, Germany) to eliminate any undercuts. Thirty canine and 30 second premolar brass abutments were duplicated (Sarbak Metal, Sarbak Co., Istanbul, Turkey) from the prepared master teeth by using a computer numerical control (CNC) machine YM 64DV jig borer (Victor, Taipei, Taiwan) 33…”

PURPOSEThe purpose of this in vitro study was to evaluate the marginal misfits of three-unit frameworks fabricated with conventional and digital impressions techniques.MATERIALS AND METHODSThirty brass canine and second premolar abutment preparations were fabricated by using a computer numerical control machine and were randomly divided into 3 groups (n=10) as follows: conventional impression group (Group Ci), Cerec Omnicam (Group Cdi), and 3shape TRIOS-3 (Group Tdi) digital impression groups. The laser-sintered metal frameworks were designed and fabricated with conventional and digital impressions. The marginal adaptation was assessed with a stereomicroscope at ×30 magnification. The data were analyzed with 1-way analysis of variances (ANOVAs) and the independent simple t tests.RESULTSA statistically significant difference was found between the frameworks fabricated by conventional methods and those fabricated by digital impression methods. Multiple comparison results revealed that the frameworks in Group Ci (average, 98.8 ± 16.43 µm; canine, 93.59 ± 16.82 µm; premolar, 104.10 ± 15.02 µm) had larger marginal misfit values than those in Group Cdi (average, 63.78 ± 14.05 µm; canine, 62.73 ± 13.71 µm; premolar, 64.84 ± 15.06 µm) and Group Tdi (average, 65.14 ± 18.05 µm; canine, 70.64 ± 19.02 µm; premolar, 59.64 ± 16.10 µm) (P=.000 for average; P=.001 for canine; P<.001 for premolar). No statistical difference was found between the marginal misfits of canine and premolar abutment teeth within the same groups (P>.05).CONCLUSIONThe three-unit frameworks fabricated with digital impression techniques showed better marginal fit compared to conventional impression techniques. All marginal misfit values were clinically acceptable.

Fatigue Behavior of Zirconia‐Ceramic, Galvano‐Ceramic, and Porcelain‐Fused‐to‐Metal Fixed Partial Dentures

Abstract: ZC specimens were not significantly affected by fatigue, whereas GC and PFM specimens were affected. All tested restorations have the potential to withstand occlusal forces applied in the posterior region.
