Effects of Substructure Color and Restoration Thickness on the Final Color of Ultra‐Translucent Zirconia Ceramics

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This in vitro study aimed to evaluate the effects of substructure color and restoration thickness on the final color of shade‐gradient ultra‐translucent zirconia ceramics. Material and Methods A total of 180 flat‐shaped ultra‐translucent zirconia specimens (5Y‐PSZ) with thicknesses of 0.4, 0.6, and 0.8 mm (n = 60) were fabricated and

Clear Aligners and Bruxism: A Systematic Review

Journal of Oral Rehabilitation, EarlyView.
This study aimed to systematically evaluate the relationship between clear aligner therapy and bruxism, including both sleep and awake bruxism, to determine whether aligners act as a neutral factor, protective agent, or risk factor. The findings indicate that no definitive conclusion can be drawn, as the current evidence is limited and contradictory ...

Effect of sintering cycle on the strength and translucency of multilayered zirconia

Journal of Prosthodontics, EarlyView.
Abstract Purpose A newly introduced sintering protocol promises to offer higher translucency while not significantly compromising the flexural strength of the material. However, the effect of the novel sintering protocol has not been thoroughly validated.

Influence of nanohydroxyapatite mouthwash on the growth of Candida albicans biofilm on milled denture surfaces: An in vitro study

Journal of Prosthodontics, EarlyView.
Abstract Purpose There is a need for effective solutions for the persistent prevalence of denture stomatitis (DS) in denture‐wearing populations. This study assessed the impact of nanohydroxyapatite (nanoHAP) nanoparticles on Candida albicans biofilm formation on milled polymethylmethacrylate (PMMA) denture bases.

Influence of the color of 3D‐printed scan aids on the trueness of complete arch digital scans

Journal of Prosthodontics, EarlyView.
Abstract Purpose To determine the influence of using 3D‐printed scan aids in varying colors on the trueness of digital scans. Materials and Methods A master cast with five multi‐unit analogues was scanned. The acquired dataset was exported to standard tessellation language (STL) file format to serve as the reference STL. 3D printing of the prototype in

The effects of anodization and instrumentation on titanium abutment surface characteristics and biofilm formation

Journal of Prosthodontics, EarlyView.
Abstract Purpose To assess the impact of anodization and instrumentation on titanium abutment surface characteristics (surface roughness and wettability) and biofilm formation (viability and mass). Materials and Methods Titanium discs were obtained from pre‐milled abutment blanks made of titanium‐6aluminum‐7niobium alloy.
