Design takeaway

Prioritize additive manufacturing (e.g., DLP) for removable complete dentures due to its demonstrated mechanical competitiveness and cost-effectiveness compared to traditional subtractive methods.

How to apply

When designing or specifying manufacturing processes for dental prosthetics, consider additive manufacturing technologies like DLP, supported by mechanical testing data and multi-criteria decision analysis for process selection.

Project actions

01When evaluating manufacturing processes for a design project, consider both performance metrics (like strength) and economic factors (like cost).
02Use comparative testing and decision-making tools (like AHP or VIKOR) to objectively rank different manufacturing options.

Method & Evidence

AimTo rank additive and subtractive manufacturing technologies for removable complete dentures based on mechanical testing results and to compare their performance against traditional methods.

MethodComparative mechanical testing and multi-criteria decision analysis (AHP-VIKOR) combined with Finite Element Method (FEM) simulation.

ProcedureRemovable complete dentures were fabricated using four different technological routes combining subtractive (hot polymerization, CAD/CAM milling) and additive (DLP) manufacturing, along with commercial denture teeth. Mechanical tests were performed on different tooth blocks, and results were analyzed using AHP-VIKOR for ranking based on reliability, durability, and stiffness. FEM simulations were also conducted.

ContextDental prosthetics manufacturing, specifically removable complete dentures.

Variables

IV["Manufacturing technology (e.g., hot polymerization, CAD/CAM milling, DLP)","Type of denture tooth block (incisors, canines, premolars, molars)"]

DV["Mechanical test results (interpreted as reliability, durability, compliance/stiffness)","Ranking of technologies"]

CV["Material properties of the denture base resin","Design of the denture teeth","Commercial denture teeth used","Loading conditions in mechanical tests","Simulation parameters in FEM"]

Strengths & Limitations

Strengths

+Comprehensive mechanical testing of denture components.
+Application of a robust multi-criteria decision analysis method (AHP-VIKOR).
+Integration of Finite Element Method (FEM) for simulation and analysis.

Limitations

The specific materials and machines used in the study might not be universally available or representative of all options within additive or subtractive manufacturing.

Reliability & validity

The study's reliability is supported by the use of standardized mechanical testing and FEM simulations. Validity is enhanced by the multi-criteria decision analysis, which accounts for multiple performance factors, and by comparing against established manufacturing protocols.

Think critically

How might the long-term wear characteristics and biocompatibility of 3D-printed dentures compare to traditionally manufactured ones, and what further research is needed to establish these differences?

Design Principles

"Emerging additive manufacturing technologies are capable of meeting or exceeding the performance benchmarks set by established subtractive manufacturing processes for complex medical devices."

This research provides crucial data for designers and manufacturers in the dental prosthetics field, validating the viability of advanced additive manufacturing techniques. Understanding the mechanical strengths and weaknesses of different production routes allows for informed material selection and process optimization, ultimately leading to more reliable and potentially more affordable patient solutions.

What This Means for Your Design

This study shows that 3D printing can make dentures just as well, and sometimes better and cheaper, than older methods.
