The Dentistry IDEA Lab is a multidisciplinary research group focused on reducing chronic pain and injury among dental professionals through ergonomic tool design. This project examines how legacy dental instruments, specifically the explorer, were designed around narrow anthropometric assumptions, limiting comfort and usability for a diverse range of practitioners.

The Dentistry IDEA Lab is a multidisciplinary research group focused on reducing chronic pain and injury among dental professionals through ergonomic tool design. This project examines how legacy dental instruments, specifically the explorer, were designed around narrow anthropometric assumptions, limiting comfort and usability for a diverse range of practitioners.

Problem

The standard dental explorer was designed using outdated anthropometric assumptions that represent a narrow subset of users. As the dental workforce has diversified, this mismatch has contributed to chronic pain, musculoskeletal strain, and reduced career longevity across dentists, hygienists, and assistants. Existing tools offer little ergonomic adaptability, forcing practitioners to physically compensate during precision work.

Approach

  • Reviewed literature and competitive products to identify instruments most strongly associated with chronic pain and strain

  • Synthesized prior lab research and interviews to evaluate feasible redesign paths

  • Narrowed scope from full instrument redesign to an attachable grip system to reduce regulatory barriers and increase adoption

  • Used sketching and early prototyping to explore grip geometry, adjustability, and accommodation of different hand sizes

Execution

I coordinated work across subteams while contributing directly to prototyping and iteration. Through rapid prototyping and user feedback, the team progressed from exploratory concepts to mid-fidelity, CAD-modeled grip designs.

  • Built low-fidelity prototypes with adjustable sizing, removable grips, and textured surfaces

  • Conducted interviews with dentists and dental assistants and integrated feedback into design iterations

  • Modeled mid-fidelity grips in SOLIDWORKS across multiple form categories

  • Iterated designs to support multiple grip styles, 360° rotation, and dual-ended tool use

Impact

  • Developed an ergonomic grip system designed to accommodate a broad range of hand sizes and grip styles

  • Converged multiple prototype directions into a single attachable grip concept optimized for precision work

  • Enabled broader adoption by avoiding full medical-device reclassification through modular design

  • Presented research and prototypes at the NEC HFES 2025 Student Conference

  • Established a clear pathway to high-fidelity prototyping informed by materials testing and pressure-sensing data
