Effect of margin thickness and cement gap on the fabrication and fit accuracy of additively manufactured crowns in definitive resins with different filler content

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate how commercially available composite resins in varying filler content affect the fabrication and fit accuracy (trueness and precision) of additively manufactured (AM) definitive crowns with different margin thickness and cement gaps by comparing them to subtractively manufactured (SM) polymer‐infiltrated ceramic crowns ...

Cemented Chromium Carbide

The Journal of the Society of Chemical Industry, Japan, 1960
Cr2O3とカーボンブラックよりCr23C6,Cr7C3,Cr3C2を製造し,その製造条件を調べ,これら各種炭化クロムとNiとの焼結体を製造し,その焼結体の機械的性質の測定,X線解析,耐酸化試験,耐食試験を行なった。その結果,Cr7C3-Ni系焼結合金は焼結不完全で,X線解析の結果,焼結体中の炭化物相は単純なCr7C3でないことがわかった。Cr3C2-15%Ni焼結合金にCr7C3を10%まで加えた場合,機械的性質,常温におけるH2SO4,HCl,NHO3,NaOHに対する耐食性には,Cr3C2-15%Ni焼結合金と著しい差は認められなかった。耐酸化性についてはCr3C2-15%Ni焼結合金が,これにCr7C3を10%加えたものまりもすぐれた耐酸化性を有することが明らかになった。各種耐食試験 ...

Comparison of surface treatment protocols for a 3D‐printable resin for definitive crowns: Effects on surface roughness and bonding performance

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to compare the effects of surface treatment protocols on the surface roughness and shear bond strength (SBS) of a three‐dimensional (3D)‐printable resin for definitive crowns. Materials and Methods A 3D‐printable resin for definitive crowns (Saremco Print Crowntec) was used to produce 168 specimens (10 × 10 × 2 mm3 ...

The oral microbiota and periodontal health in orthodontic patients

Periodontology 2000, EarlyView.
Abstract The oral microbiota develops within the first 2 years of childhood and becomes distinct from the parents by 4 years‐of‐age. The oral microbiota plays an important role in the overall health/symbiosis of the individual. Deviations from the state of symbiosis leads to dysbiosis and an increased risk of pathogenicity.
