Application

Design takeaway

In designing therapeutic oral appliances, prioritize digital modelling and manufacturing techniques when precise occlusal balance is a critical functional requirement.

How to apply

When designing custom-fit medical or dental devices where precise anatomical or functional alignment is crucial, explore the use of CAD/CAM technologies for fabrication.

Project actions

  • 01When designing a device that requires precise fitting, consider how digital modelling (like CAD) can improve accuracy.
  • 02Think about how the manufacturing process can directly impact the device's performance and user experience.

Method & Evidence

AimTo compare the clinical efficacy and patient-centered outcomes of digitally fabricated versus conventionally fabricated stabilization splints in managing pain-related temporomandibular disorders.
MethodRandomized Controlled Crossover Trial
ProcedureTwenty-four patients with pain-related temporomandibular disorders were randomly assigned to wear either a digitally fabricated or a conventionally fabricated stabilization splint for six weeks, followed by a three-week washout period, and then the alternative splint for another six weeks. Outcomes measured included pain intensity, electromyographic activity of masticatory muscles, occlusal parameters, and oral health-related quality of life.
Sample24 participants
ContextDental and medical device design, specifically for therapeutic oral appliances.

Variables

IVType of stabilization splint (Digital vs. Conventional)
DVPain intensity, EMG activity, occlusal parameters, oral health-related quality of life
CVDuration of wear (6 weeks), washout period (3 weeks), patient diagnosis (pain-related TMD), age range
04

Strengths & Limitations

Strengths

  • +Randomized crossover design minimizes inter-individual variability.
  • +Inclusion of multiple outcome measures (pain, muscle activity, occlusion, quality of life) provides a comprehensive evaluation.

Limitations

The study was a pilot, meaning it had a small number of participants. The specific materials and software used for digital fabrication might influence results, and these might not be generalizable to all digital methods.

Reliability & validity

The randomized crossover design enhances internal validity by controlling for individual differences. The use of objective measures like EMG and T-Scan, alongside subjective patient-reported outcomes, contributes to a more robust assessment. However, the pilot nature and specific fabrication methods may limit generalizability.

Think critically

To what extent can the superior occlusal symmetry achieved by digital splints be attributed to the inherent precision of CAD/CAM technology versus the skill of the technician in conventional fabrication?

05

Design Principles

"Leverage digital fabrication for enhanced precision in therapeutic device design."

This finding highlights the potential of advanced digital modelling and manufacturing techniques to improve the functional outcomes of therapeutic devices. For designers, it underscores the value of leveraging CAD/CAM for creating patient-specific solutions that offer greater accuracy and potentially better therapeutic results.

06

What This Means for Your Design

Making mouth splints using computers (digital) is better at making them fit perfectly for chewing than making them the old way (conventional), which helps reduce pain and improve how people feel about their oral health.
