Material Selection for CAD/CAM Dental Restorations: Balancing Strength, Aesthetics, and Clinical Case

The selection of chairside CAD/CAM materials in restorative dentistry requires a careful balance of mechanical strength, aesthetic properties, and the specific clinical needs of the patient.

Journal of Functional Biomaterials · 2025

Key Findings

01Chairside CAD/CAM materials can be broadly categorized into feldspathic ceramics, leucite-reinforced ceramics, lithium disilicate, zirconia, hybrid ceramics, and acrylic resins.
02Material selection is influenced by factors such as required strength, desired aesthetics, ease of fabrication, and patient-specific medical conditions.
03Minimally invasive treatment principles should guide the selection process to achieve optimal functional and aesthetic outcomes.

Application

Design takeaway

How to apply

When faced with a design challenge for a dental restoration, create a matrix comparing available CAD/CAM materials against key performance indicators like flexural strength, fracture toughness, and aesthetic properties (e.g., color stability, translucency).

Project actions

01When researching materials for a design project, create a comparison table that lists the pros and cons of each option.
02Consider how the material's properties will affect the user's experience and the product's longevity.

Method & Evidence

AimWhat are the key properties and clinical considerations for selecting appropriate chairside CAD/CAM biomaterials in restorative dentistry?

MethodLiterature Review

ContextRestorative Dentistry

Variables

IVType of CAD/CAM material

DVMechanical properties (e.g., strength, fracture toughness), Aesthetic properties (e.g., translucency, color stability), Clinical success rate

CVPatient's oral health status, Dentist's fabrication technique, Specific clinical application (e.g., crown, veneer, inlay)

Strengths & Limitations

Strengths

+Provides a broad overview of current CAD/CAM materials.
+Connects material properties to clinical applications.

Limitations

The availability and cost of specialized materials can be a practical limitation for student design projects.

Reliability & validity

The validity of this review relies on the quality and scope of the included studies. Reliability is enhanced by the systematic approach to literature synthesis.

Think critically

How might advancements in material science, such as self-healing composites or bio-integrated ceramics, further revolutionize the design and application of dental restorations?

Design Principles

"Material selection should be driven by a holistic understanding of performance requirements, aesthetic goals, and the specific application context."

As digital fabrication technologies become more prevalent, designers and engineers working with dental prosthetics must understand the diverse properties of available biomaterials. This knowledge is crucial for creating restorations that are not only functional and durable but also aesthetically pleasing and suitable for individual patient conditions.

What This Means for Your Design

There are many different materials used for making dental crowns and fillings with computers. Each material is good for different things – some are super strong, others look very natural. Designers need to know these differences to pick the best material for each person's tooth.

How to use in your project

1.Use this research to justify the selection of specific materials for your design project, referencing the trade-offs between strength, aesthetics, and cost.

Paragraph starter

The selection of materials for restorative dental applications using CAD/CAM technology necessitates a careful evaluation of their mechanical properties, aesthetic qualities, and suitability for individual clinical scenarios. As explored in the literature, materials such as lithium disilicate and zirconia offer high strength, while others like hybrid ceramics provide a balance of properties. The guiding principle of minimally invasive treatment further emphasizes the need for precise material selection to achieve optimal functional and aesthetic outcomes, directly informing design choices for dental prosthetics.
