Internal and marginal fits of 3D-printed provisional prostheses: comparative effect of different printing parameters.
Front Oral Health
December 2024
Department of Substitutive Dental Sciences, College of Dentistry, Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia.
Objectives: The influence of printing parameters on the marginal and internal fit of three-dimensional (3D) printed interim fixed partial dentures (IFPDs) has been understudied. This investigation sought to elucidate the impact of printing orientation and post-curing time on these critical factors.
Methods: A total of 260 3-Unit IFDPs were printed using two different resins (130/NextDent C&B MFH and 130/ASIGA DentaTOOTH).

Article Synopsis
- The study examined the accuracy and fit of 3D-printed indirect bonding trays made from different photopolymer resin materials, using a maxillary plaster model and replicas for testing.
- Six types of trays were printed, revealing significant linear transfer errors, mainly in the vertical direction, with specific resins showing varying levels of precision.
- The findings highlighted that linear errors are more influenced by the material used than angular errors, indicating the need for designs tailored to the specific resins to enhance the fit and alignment of brackets.
Fit, Precision, and Trueness of 3D-Printed Zirconia Crowns Compared to Milled Counterparts.

Precise fit of a crown and accurate reproduction of the digital design are paramount for successful treatment outcomes and preservation of clinician and technician time. The study aimed to compare the internal fit, marginal adaptation, precision, and trueness of 3D-printed zirconia crowns compared to their milled counterpart. A total of 20 monolithic 3 mol% yttria stabilized-zirconia crowns (n = 10) were made using computer-assisted design (CAD) followed by additive (3D-printed) and subtractive (milled) manufacturing.

*Daniel Sundfeld, DDS, MSc, PhD, adjunct professor, Department of Restorative Dentistry and Prosthodontics, Ingá University Center - UNINGÁ, Maringá, PR, Brazil.
Objectives: To evaluate the bond strength of a resin luting agent to a lithium disilicate glass-ceramic after the use of different fit-checking materials and cleaning protocols.
Methods And Materials: Two hundred and forty-two (242) ceramic specimens were etched with 5% hydrofluoric acid for 20 seconds and distributed into 22 groups (n=10), in total. Four (4) groups were created based on fit-checking material and that had no following cleaning protocol: no fit-checking material used (control group); articulating paper; articulating spray; and fit-checker liquid.
[Marginal features of CAD/CAM laminate veneers with different materials and thicknesses].

Objective: To analyze the marginal roughness and marginal fitness of chairside computer-aided design and computer-aided manufacturing (CAD/CAM) laminate veneers with different materials and thicknesses, and to provide a reference for the clinical application of laminate veneers.
Methods: The butt-to-butt type laminate veneers were prepared on resin typodonts, the preparations were scanned, and the laminate veneers were manufactured by chairside CAD/CAM equipment. The laminate veneers were divided into four groups (=9) according to the materials (glass-matrix ceramics and resin-matrix ceramics) and thickness (0.
