Grade
30/30

In short

Challenge
Appointments, records split between paper and digital, X-rays and team messages are scattered across different tools: the dentist loses time and information.
Solution
A mobile app for dentists designed on the Material Design 3 design system: ten screens that bring the clinical day together, each built on a need that came out of research.
Delivered
A high-fidelity, clickable prototype in Figma, with every screen traced back to the needs it solves.

01 · The problem

A dentist’s day lives in disconnected tools

During my internship at a dental practice I watched the working day up close: appointments, records split between paper and digital, X-rays and team messages are spread across different tools.

The core issue research found: scattered information and a workflow that overloads the dentist.

Four ways of working, seven needs

Four personas, the same role and opposite habits. Every screen answers at least one of their problems.

  • LucaThe precise one
    • 01 Too much information to keep in mind
    • 03 Misaligned internal communication
    • 04 Important data that never gets written down
    • 05 Different working styles to reconcile
    • 07 Stress and tension in the team
  • MarcoThe scatterbrain
    • 02 Files, materials and notes that get lost
    • 03 Misaligned internal communication
    • 06 Delays in clinical procedures
    • 07 Stress and tension in the team
  • SaraThe overloaded one
    • 01 Too much information to keep in mind

02 · The research

Who uses it, and how they work

The process

Double Diamond, from problem to solution

Two rounds of diverging and converging: first on the problem, then on the solution.

01 / 04 · Double Diamond

Discover

Stakeholders split into three levels with Eason’s model, then the work observed in the practice (contextual inquiry).

  1. PrimaryGeneral and specialist dentists

    They use the app every day, between one visit and the next. Every screen is designed for them.

  2. SecondaryPatients and chairside assistants

    They don’t use it, but they feel it: shorter waits, clear instructions, an aligned team.

  3. TertiaryThe practice owner

    Decides whether to adopt it: looks at how the practice is organised and the time saved.

02 / 04 · Double Diamond

Define

The experience map follows the dentist from planning to after the visit: the goal and the mood of each phase.

  1. PlanningKeep appointments and availability under controlConfusion → clarity
  2. Before the visitAlign the team on procedures and patientsAnxiety → team in sync
  3. During the visitTreat efficiently, without delays or lost filesStress → efficiency
  4. After the visitComplete the records and the follow-upUncertainty → control

03 · The choices

Three ideas, two dropped

03 / 04 · Double Diamond

Develop

Every idea tested with the devil’s & angel’s advocate; the ones that survived became wireframes.

  1. Idea 01 Dropped

    Dictating notes by voice during the visit

    Devil’s advocate

    With gloves on and a patient in the chair, the voice records what it shouldn’t, and the practice is noisy.

    Angel’s advocate

    No note lost while the hands are busy.

    Instead

    Quick notes added in one tap, between one visit and the next.

  2. Idea 02 Dropped

    An internal team chat

    Devil’s advocate

    One more channel to check: it adds noise instead of aligning people.

    Angel’s advocate

    Instant communication between colleagues.

    Instead

    Shared checklists and protocols: alignment comes from the procedure, not from messages.

  3. Idea 03 Kept

    Alerts at the top of the dashboard

    Devil’s advocate

    Too many warnings become noise and get ignored.

    Angel’s advocate

    Delays and allergies visible before anything else.

    With a limit

    One highlighted alert at a time, the rest in the notification badge.

04 · The project

Ten screens, one day

04 / 04 · Double Diamond

Deliver

Wireframes taken to high fidelity on the Material Design 3 design system, with one primary action per screen.

01/04 Dashboard

The day in a single view

Alerts get the top spot: a late patient stands out before anything else, with the two actions needed right away. Below, the day’s summary and the appointments in time order.

  1. The alert at the top of the hierarchy
  2. The summary of the day
  3. The status of every appointment

AnswersInformation overload · Unrecorded data · Delays

02/04 Agenda

Time at a glance

The week stays at the top, the day runs as a timeline and every appointment shows its status. The + button is the only strong action.

  1. The week always in view
  2. Status in colour and label
  3. One primary action

AnswersInformation overload · Unrecorded data

03/04 Patients, notes and archive

Every piece of information in one place

The record brings together contacts, allergies, the next appointment and documents. Notes filter by urgency; the archive by type, in one grid.

AnswersLost files · Unrecorded data

04/04 Procedure checklists

The same protocol for the whole practice

Every procedure is a sequence of steps, the same for every dentist. It is ticked step by step with progress in view: no stage skipped.

  1. How many steps each procedure has
  2. The progress of the open procedure
  3. The steps to tick, in order

AnswersMisaligned team · Different styles · Delays

05 · The outcome

An app ready to be put to the test

What I delivered

A clickable Figma prototype that follows the dentist through the whole day: dashboard, agenda, patients, notes, checklists and archive.

What I learned

Don’t draw until the problem is clear, and tie every choice to a real need: then every screen defends itself.

Next step

A usability test with the practice’s dentists on two tasks, finding a document and completing a procedure, measuring time and errors.
