Advanced Functional Materials, EarlyView.This study develops a novel atomic engineering strategy to fine‐tune the spin state of α‐Fe2O3 catalysts toward a medium‐spin state, thereby modulating peroxymonosulfate activation and selectively yielding surface‐bound radicals. Compared with free radicals, surface‐bound radicals exhibit moderated oxidation potential, extended lifespan, surface ...

Marginal Fit of Electroformed Ceramometal Crowns
Journal of Prosthodontics, 1996PurposeA method of fabricating ceramometal crowns using gold copings produced by an electroforming process has been described, which purportedly results in restorations exhibiting an excellent marginal fit. This study compares the fit of electroformed ceramometal crowns with ceramometal crowns fabricated using conventional lost wax casting techniques ...

Marginal fit of direct temporary crowns
The Journal of Prosthetic Dentistry, 1982This study compared the effect that shrinkage of four brands of temporary crown and fixed partial denture resins has on the marginal fit of crowns made from them. Under the conditions of this study, crowns made from Coldpac had marginal discrepancies approximately four times larger than those made from Scutan.

Marginal fit of castable ceramic crowns
The Journal of Prosthetic Dentistry, 1992The objective of this study was to measure marginal fit of castable ceramic versus gold crowns. Full veneer gold and ceramic crowns were made on Ivorine dies. Crowns were cemented, embedded, sectioned faciolingually and mesiodistally, and photographed for measurement of absolute marginal discrepancies (cavosurface angle to casting margin) to evaluate ...

Considerations in measurement of marginal fit
The Journal of Prosthetic Dentistry, 1989The terminology describing "fit" and the techniques used for measuring fit vary considerably in the literature. Although fit can be most easily defined in terms of "misfit," there are many different locations between a tooth and a restoration where the measurements can be made.

Cervical marginal fit of proximal amalgam restorations
Journal of Dentistry, 1994This study investigated the relationship between the adaptation, apical location and gap width of the cervical margin of proximal amalgam restorations. Three hundred and seventeen proximal cervical margins were studied in 243 extracted teeth. The restorations were categorized as 'flush fitting'; 'small overhang', or 'large overhang', based on ...

Marginal fit changes during porcelain firing cycles
The Journal of Prosthetic Dentistry, 1995The marginal fit changes that occur during the procelain firing cycles of palladium-copper and nickel-chromium copings both with shoulder and chamfer finish lines were investigated with scanning electron microscopy. Three copings from each alloy test group were used as nonporcelainized controls.
