01

Key Findings

  • 01No statistically significant difference was found in patients' subjective perception of comfort between traditionally manufactured splints and digitally designed and 3D-printed splints.
  • 02The additive manufacturing process for anterior deprogrammers was successfully implemented, with a complete data protocol for production, CAD, and 3D printing.

Application

Design takeaway

When designing custom medical devices, consider leveraging CAD and 3D printing to achieve comparable or superior results to traditional manufacturing, especially concerning user comfort and fit.

How to apply

Explore the use of CAD software and 3D printing for creating custom-fit assistive devices, prosthetics, or ergonomic tools where patient comfort is a key performance indicator.

Project actions

  • 01When designing a product that requires a precise fit, consider how digital modelling and rapid prototyping can help achieve this.
  • 02Think about how to measure user comfort or satisfaction in your design project.

Method & Evidence

AimTo investigate whether 3D-printed anterior deprogrammers, designed using CAD, offer comparable subjective comfort to traditionally manufactured splints.
MethodComparative pilot study
ProcedureTwo anterior deprogrammers were designed using CAD and additively manufactured from biocompatible material. These were then compared to traditionally produced splints. Patient comfort was monitored over a ten-week period.
Sample2 participants
ContextDental prosthetics and restorative dentistry

Variables

IVManufacturing method (traditional vs. 3D printed)
DVPatient's subjective perception of comfort
CVMaterial biocompatibility, design protocol, monitoring period (ten weeks)

Strengths & Limitations

Strengths

  • +Pioneering use of CAD and 3D printing for this specific dental application.
  • +Focus on patient-reported outcomes (comfort).

Limitations

A small sample size means the results might not apply to everyone. The study only looked at comfort, not other factors like durability or cost.

Reliability & validity

The validity of the findings is limited by the small sample size. Reliability could be improved by using standardized comfort rating scales and a larger participant pool.

Think critically

While this study found no difference in comfort, what other factors might be important when comparing 3D-printed dental devices to traditional ones (e.g., cost, durability, material properties, production time)?

05

Design Principles

"Digital fabrication methods can yield user-centric outcomes equivalent to established techniques in specialized fields."

This research demonstrates that advanced digital fabrication techniques can be effectively applied in dental prosthetics, offering a viable alternative to conventional methods. Designers and engineers can leverage these findings to explore digital workflows for custom medical devices, potentially improving efficiency and patient outcomes.

06

What This Means for Your Design

Making dental mouthguards using computer design and 3D printing is just as comfortable for patients as the old way of making them.
