Additive Manufacturing of Dental Ceramics Approaches Conventional Mechanical Properties

Additive manufacturing techniques for dental ceramics are demonstrating mechanical properties that are increasingly comparable to those achieved through traditional methods.

Frontiers in Dental Medicine · 2025

Key Findings

01The mechanical properties of additive-manufactured ceramics, including flexural strength and hardness, are trending towards values comparable to those of conventionally manufactured ceramics.
02Common processing defects in AM ceramics, such as porosity and cracks, still influence their overall performance and reliability.
03Further research is needed to fully understand the long-term performance and the impact of printing parameters like layer orientation.

Application

Design takeaway

How to apply

When specifying materials for additive manufacturing of dental components, consult the latest research on AM ceramic properties and consider the trade-offs between design complexity and material reliability.

Project actions

01When evaluating additive manufacturing processes for ceramic components, critically assess the reported mechanical properties in relation to the potential for defects.
02Consider how printing orientation might affect the structural integrity of the final product.

Method & Evidence

AimWhat are the mechanical properties of additive-manufactured restorative ceramics in comparison with subtractive manufacturing?

MethodSystematic Review

ProcedureA systematic literature search was conducted across PubMed/MEDLINE, Web of Science, and Scopus for articles published between 2019 and 2023. Forty studies were analyzed, focusing on the mechanical properties (density, flexural strength, fracture toughness, Young's modulus, hardness) and performance of various AM ceramics, including zirconia, alumina, lithium disilicate, and glass ceramics.

ContextDental restorative materials and manufacturing processes.

Variables

IVAdditive manufacturing technique, material type, printing parameters (e.g., layer orientation).

DVMechanical properties (density, flexural strength, fracture toughness, Young's modulus, hardness), performance, presence of defects.

CVMaterial composition, post-processing treatments, testing methodologies.

Strengths & Limitations

Strengths

+Comprehensive review of recent literature on AM ceramics.
+Focus on critical mechanical properties relevant to dental restorations.

Limitations

The long-term durability and clinical success of AM ceramics are not yet fully established, and the impact of specific printing parameters on these outcomes requires more investigation.

Reliability & validity

The systematic review methodology enhances the reliability of the findings by synthesizing data from multiple studies. Validity is supported by the focus on established mechanical testing standards within the included research.

Think critically

To what extent do the current limitations in defect control and long-term performance of AM ceramics outweigh the benefits of design freedom and customization in critical applications like dental restorations?

Design Principles

"Material performance in additive manufacturing is converging with conventional methods, but process-induced defects remain a critical factor in design and application."

This advancement in additive manufacturing (AM) for dental restorations signifies a potential shift in production paradigms. Designers and manufacturers can explore new geometries and customization options while moving closer to the material performance expected from established techniques.

What This Means for Your Design

Making dental crowns and fillings with 3D printers is getting almost as strong as making them with old methods, but we still need to make sure they last a long time and don't have tiny flaws.

How to use in your project

1.Use this research to justify the selection of a particular manufacturing method for ceramic components, highlighting the trade-offs between innovation and established performance metrics.
