Application

Design takeaway

For current design projects involving fixed dental restorations, prioritize the use of subtractive manufacturing techniques due to their established clinical efficacy and reliability.

How to apply

When designing dental prosthetics, consider the material properties and manufacturing constraints associated with subtractive methods like milling. Evaluate the cost-effectiveness and precision achievable with subtractive techniques for the specific restoration requirements.

Project actions

01When designing dental prosthetics, consider the manufacturing process early on.
02Research the advantages and disadvantages of both subtractive and additive manufacturing for your specific design.

Method & Evidence

AimTo systematically review and evaluate the current knowledge on subtractive and additive manufacturing technologies for metal-ceramic fixed dental restorations.

MethodSystematic Review

ProcedureA systematic review was conducted by searching multiple databases (Science Direct, PubMed, Web of Science, Google Scholar) and performing a hand search of the literature. Relevant articles published between 2008 and 2021 were collected, analyzed, and screened based on titles, abstracts, and full texts. Search terms included 'Computer-Aided Design', 'CAD/CAM', 'dentistry', 'dental fabrication', 'restoration', and 'additive manufacturing'.

ContextDental prosthetics manufacturing, specifically fixed dental restorations using metal-ceramic materials.

Variables

IVManufacturing technology (subtractive vs. additive)

DVSuitability/efficacy for fixed dental restorations

CVMaterial type (metal-ceramic), type of restoration (fixed dental restoration), publication date range.

Strengths & Limitations

Strengths

+Comprehensive search strategy across multiple databases.
+Inclusion of a defined time frame for relevant literature.

Limitations

The review's findings are based on literature up to 2021, and additive manufacturing technologies are rapidly evolving.

Reliability & validity

The systematic review methodology enhances reliability by ensuring a thorough and unbiased search. Validity is supported by the inclusion criteria and systematic screening of articles.

Think critically

Given the rapid advancements in additive manufacturing, how might the findings of this review change in the next 5-10 years?

Design Principles

"Prioritize established and clinically validated manufacturing processes for critical applications unless significant advantages are demonstrated by emerging technologies."

This insight is crucial for designers and manufacturers of dental prosthetics, guiding material selection and production processes. Understanding the current efficacy of different manufacturing approaches directly impacts the quality, durability, and clinical success of dental restorations.

What This Means for Your Design

For making dental crowns and bridges, the way we cut away material (subtractive) is currently better and more reliable for everyday use than building it up layer by layer (additive).
