Abstract Objectives To compare the strength and translucency of CAD/CAM zirconia blocks, with traditional high‐speed sintering, to lithium disilicate. Materials Methods Three materials (Katana STML Block, Prettau Anterior, Zpex Smile) were tested either (7 hours) or (18 30 minutes in a SpeedFire furnace) sintering. A disilicate material (IPS e.max CAD) was as reference. Three‐point bend flexural specimens (16 mm × 4 1.2 mm, n = 10) on 14‐mm‐separated supports loaded failure at 1 mm/min....
To determine if surface treatment and cement selection for traditional 3 mol% yttria partially stabilized zirconia (3Y-PSZ), "translucent" 5 yttria-stabilized (5Y-Z), or lithium disilicate crowns affected their fracture load.Crowns with 0.8 mm uniform thickness (96, n = 8/group) were milled of 3Y-PSZ (Lava Plus), 5Y-Z Esthetic), (e.max CAD) sintered/crystallized. Half the either particle-abraded 30 µm alumina (zirconias) etched 5% hydrofluoric acid (lithium disilicate), other half received...
Abstract Objectives To compare the filler weight percentage (wt%), and resin composition, flexural strength, modulus, hardness of several 3D‐printed resins to direct indirect restorative materials. Materials Methods Four (C&B MFH, Ceramic Crown, OnX, OnX Tough), one milled composite (Lava Ultimate), conventional (Filtek Supreme), ceramic (IPS e.max CAD) were evaluated. Filler wt% was determined by burned ash technique, particle morphology composition analyzed scanning electron microscopy...
Two 3D-printed crown materials (Crown and Ceramic Crown) were examined to determine the best surface treatment primers for bonding. Discs of two printed mounted with their "intaglio" surfaces untouched. Half specimens from each group sandblasted 50 µm alumina. Then, divided into four groups (n = 10): Gr1-no further treatment; Gr2-one coat silane; Gr3-one universal adhesive; Gr4-one silane, then one adhesive. Bond strength prepared an Ultradent shear bond apparatus using Filtek Supreme...
Abstract Purpose To determine the best method of cleaning saliva‐contaminated zirconia in preparation for resin bonding. Material and Methods Flat blocks were particle abraded with aluminum oxide divided into eight groups (n = 10). Groups 1 to 4 first treated one coat an MDP primer (Z‐prime Plus) 5 8 left untreated. A thin fresh whole saliva was painted on all specimens (except control, group 1) contact 3 minutes. The then cleaned by rinsing water 20 seconds (groups 2 5), or 35% phosphoric...
Abstract Objective To evaluate the gloss and stain resistance of several new ceramic‐polymer CAD / CAM blocks Materials Methods Specimens (4 mm) were sectioned from: Enamic (polymer‐infused ceramic), LAVA Ultimate (nano‐ceramic reinforced polymer), e.max (lithium disilicate), P aradigm C (porcelain), MZ 100 (composite). wet polished on a polishing wheel to either 320 grit silicon paper (un‐polished, N = 8) or 2000 carbide papers followed by 0.05 μm alumina slurry (polished, 8). Initial color...
ABSTRACT Objectives To evaluate the clinical performance and survival of Enamic crowns placed in a prosthodontic dental practice. Methods Thirty‐five patients 45 were included study. At 1‐year recall appointments, restorations examined for survival. 2‐year appointment, all clinically evaluated by an independent evaluator CDA criteria. Kaplan‐Meier method log‐rank test used to compare with resin resin‐modified glass ionomer (RMGI) cements. Results Out that followed, 2 lost follow‐up 1 year 7...
Abstract The aim of this study is to examine the effects nanofiller concentration on mechanisms wear a dental composite. Nanofilled composites were fabricated with bisphenol A glycidyl methacrylate polymer and 40 nm SiO 2 filler particles at three loads (25, 50, 65 wt %). elastic modulus, flexural strength, hardness unfilled resin measured. materials ( n = 8) tested in modified testing device 50,000, 100,000, 200,000 cycles 20 N force 1 Hz. 33% glycerine lubricant stainless steel antagonist...
