Precision dispensing meets ergonomic excellence.
Dental assistants face inefficiencies while delivering composite resins because standard syringes require high force, risk material waste, and lack intuitive feedback. Nuance solves these issues with reduced extrusion effort, visual and haptic dosing clarity, and hygienic design features.
“From the initial meeting with RKS in 93, I knew we would be working together for decades. Their methods, dedication and talent helped us emerge from a start-up to a leading global brand in dentistry.”
Robert Hayman, Co-Founder and CEO Discus Dental

Research Insights & Discovery
Key Outputs
- User Personas
- Psycho-Aesthetics® 2.0 Map
- Benchmarking
- Opportunity Areas & Design Criteria
RKS conducted competitive benchmarking and ethnographic field studies in dental clinics to identify key friction points: high extrusion force, cap loss, dosing uncertainty, and visual confusion in shade selection. We applied Psycho‑Aesthetics® to position Nuance in the “enriched/versatile” design quadrant for empowerment and clarity.
How We Used Psycho-Aesthetics™ to Identify Unique Opportunities in the Project.
Using our proprietary Psycho-Aesthetics® 2.0 framework, we conducted in-depth interviews and ethnographic observation in diverse lab settings. We identified key emotional and usability pain points, such as intimidation with complex interfaces, workspace clutter, and trust in precision. These insights guided both the form and interface strategy, ensuring approachability and confidence in operation.


Industrial Design Concept Development
Key Outputs
- Form Factor Concepts
- CMF Strategy
- Refined Industrial Design Language
We redesigned the syringe with a rectangular barrel for natural gripping, integrated rubberized dosing mechanism requiring ~50% less force than comparable units, and hinged cap to prevent loss and contamination. Standing base ensures visibility and accessibility on trays.

Branding Design
Key Outputs
- Consistent visual identity aligned with dental office workflows
- Shade coded graphics for fast material selection
- Labeling guidelines designed for hygienic environments
To reinforce Discus/Philips’ positioning in uncompromising performance and clinical precision, we applied color coded shade graphics, digital capable branding elements, and refined cap and label typography. The syringe delivers intuitive differentiation and professional polish.

Product Engineering & Prototyping
Key Outputs
- Performance prototypes with calibrated screw dosing mechanism
- Audible / tactile “click” for dosing confirmation
- Tooling-ready CAD/CAM data for scalable production
RKS supported integrated engineering to achieve unit dosing (~0.1 g per half-rotation click), dose tracking ridges, and material visibility via tick mark windows. Multiple prototype iterations balanced form, feedback, and precision under clinical testing.



Key Outcomes and Results
Key Accomplishments
- 2011 Silver International Design Excellence Award (IDEA)
- Ease of extrusion reduced dispensing force by ~50%, lowering user fatigue.
- Generated strong patents and industry recognition.
RKS Design’s collaboration on the Nuance Composite Syringe redefined dental composite delivery through deep user insight, ergonomic innovation, and perceptive branding. By fusing reduced force dispensing, intuitive dosing feedback, and hygienic form, Nuance transformed a routine tool into an award winning design, empowering professionals and reshaping expectations in restorative dentistry.
