Assessment of fit accuracy and retentive strength of additively manufactured zirconia crowns luted to Ti‐base abutments with different resin cements: An in vitro study

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study investigated the influence of cement gap size on the marginal and internal fit, and cement gap size and type on retention of additively manufactured zirconia (AM‐Z) crowns on titanium bases (Ti‐base). Materials and Methods A total of 135 zirconia crowns were designed with three different cement gap sizes: 20 µm, 30 µm, and ...

Comparison of the effect of storage media on shear punch strength of resin luting cements

, 2010
Objectives: To measure the shear punch strength of eight resin-containing luting cements before and after immersion in acidic solution and ethanol at different temperatures (37° C and 60 °C). Method: Specimens were prepared from six resin luting cements;

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 ...

Bond strength enhancement for additively manufactured zirconia: Micro‐retentive design approach

Journal of Prosthodontics, EarlyView.
Abstract Purpose To investigate the effect of digitally designed micro‐retention features on the bond strength of additively manufactured (AM) zirconia copings. Materials and Methods Sixty titanium base abutments (NobelParallel, NobelBiocare), pretreated with 50 µm alumina particles were divided into four groups (n = 15 per group); one group with ...

An Insight into the Bioactive Luting Cement

UNIVERSITY JOURNAL OF DENTAL SCIENCES, 2023
A large number of luting agents (dental cements) are available and proper selection can be a daunting task and is usually based on a practitioner’s reliance, on their experience and preference. The literature continues to repeat that ‘‘No available product satisfies the requirements for an ideal luting agent and comprehensive patient care requires ...

Effect of material, prosthesis height, and aging on the fracture strength of additively and subtractively manufactured implant‐supported cantilevered prostheses

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to evaluate the inherent and after cyclic loading fracture strength of implant‐supported cantilevered fixed prostheses fabricated from recently introduced additively manufactured (AM) and subtractively manufactured (SM) materials, considering variations in prosthesis height.

Solubility of luting cements in organic acids.

Nihon Hotetsu Shika Gakkai Zasshi, 1988
The solubility of luting cements was investigated in an environment of flowing buffered solutions of organic acids, and experimental results were used to standardize the condition of buffered solutions of organic acids. Then the influence of the differences of zinc phosphate cement film thickness, liquid-powder ratio, and cement film thickness in the ...

The effects of material thicknesses and substrates on the translucency and color masking ability of additively manufactured definitive crown materials

Journal of Prosthodontics, EarlyView.
Abstract Purpose To investigate the translucency of the new 3D‐printable materials concerning thickness and the color masking ability of each material against different substrate colors. Materials and Methods Ninety square‐shaped specimens (12.0 mm × 12.0 mm) of two new 3D‐printable materials: ceramic‐infiltrated hybrid resin composite (VS) and light ...
