Build a Custom AI Model to Predict Dental No-Shows
A custom AI algorithm to predict dental no-shows is a fixed-price build. The cost depends on your practice management software and data quality.
Scope is determined by the integration complexity with your Practice Management Software (PMS) and the volume of historical data available for training. A clinic with two years of clean appointment data from a system like Open Dental is a faster build than one with fragmented records from a legacy, on-premise PMS.
We recently built a prediction system for a 3-dentist clinic with 15 staff members. Using 18 months of appointment data from their Dentrix system, we built and deployed the model in 3 weeks. Their front desk now has a prioritized call list each morning, and their no-show rate dropped from 14% to 9% in the first month.
What Problem Does This Solve?
Most dental clinics rely on their Practice Management Software's built-in flagging systems. These are simple rule-based alerts, often just flagging patients with a prior no-show. This approach fails because it cannot learn from complex patterns. It treats a new patient booking a high-value procedure a day in advance the same as a loyal patient's 6-month cleaning booked months ago, even though their risk profiles are completely different.
Third-party communication tools like Weave or Lighthouse 360 are excellent for sending appointment reminders, but they are not prediction engines. They confirm delivery of an SMS, but they cannot provide a risk score to help your staff prioritize follow-up calls. A front desk team of 3 trying to confirm 80 appointments for the next day still has to guess who is most likely to cancel, wasting hours calling low-risk patients.
This workflow is inefficient because it treats all unconfirmed appointments as equally risky. The critical signals that predict no-shows, like booking lead time, time of day, procedure type, and frequency of past reschedules, are buried in your data. Without a model to surface these patterns, your staff is flying blind.
How Does It Work?
First, we securely access an export of your appointment data, typically the last 24 months. We use Python and the pandas library to clean this data, structuring it for analysis. From this, we engineer over 30 predictive features, including 'days_since_last_visit', 'booking_lead_time_in_hours', and 'previous_cancellation_rate'. A minimum of 500 past no-show events is required for the model to learn effectively.
We then train a gradient boosting model using XGBoost. This model is highly effective at finding non-linear patterns in patient behavior and appointment data. Instead of a simple yes/no flag, it generates a precise no-show probability score from 0.0 to 1.0 for every future appointment. We typically find that patients scoring above 0.75 account for over 80% of all no-shows.
The trained model is packaged in a FastAPI application and deployed on AWS Lambda. This serverless architecture is cost-efficient, typically running under $30 per month. A scheduled function runs every night at 2 AM, pulling the next 72 hours of appointments from your PMS, scoring each one, and writing the risk score back to a custom note or field. The entire process for a clinic with 300 daily appointments completes in under 90 seconds.
We provide a simple dashboard built with Streamlit for your office manager. It displays a daily, prioritized call list of high-risk patients. The dashboard also monitors the model's F1-score over time against actual outcomes, which are logged to a Supabase database. If performance degrades, we receive a CloudWatch alert and can quickly retrain the model on fresh data.
What Are the Key Benefits?
Get No-Show Predictions in 3 Weeks
Your front desk receives a prioritized call list in 15 business days, not next quarter. We integrate directly with your existing PMS with minimal disruption.
Fixed-Price Build, No Per-Patient Fees
We deliver the project for a single development cost. Your only recurring expense is for AWS hosting, which is often less than $30 per month.
You Own The Code and The Model
We provide the full Python source code in your private GitHub repository. You are never locked into a proprietary platform or a recurring SaaS license.
Automated Daily Scoring and Monitoring
The system runs automatically every night without manual intervention. We use structlog for detailed logging and CloudWatch for failure alerts.
Works With Your Existing Dental Software
We build connectors for major PMS platforms like Dentrix, Eaglesoft, and Open Dental. Your staff sees the risk score inside the tools they already use every day.
What Does the Process Look Like?
PMS Data Audit (Week 1)
You provide a secure data export of your appointment history. We deliver a data quality report and a list of predictive features we can build.
Model Training and Validation (Week 2)
We train the prediction model on your historical data. You receive a performance report detailing its accuracy on past no-shows from your clinic.
Deployment and Integration (Week 3)
We deploy the scoring API and connect it to your PMS. You get a live dashboard with the first set of risk scores for upcoming appointments.
Monitoring and Handoff (Week 4+)
We monitor live performance for 30 days to ensure accuracy. You receive a complete runbook and an optional flat-rate monthly maintenance plan.
Frequently Asked Questions
- How do you determine the final cost and timeline?
- The primary factor is your Practice Management Software. Systems with a direct database connection or documented API, like Open Dental, are faster builds. Legacy systems requiring manual data exports take more time. A typical project is 3-4 weeks. We provide a fixed-price quote after our initial discovery call, where we review your current setup and data availability.
- What if the nightly scoring process fails?
- The system is designed for resilience. If the API cannot connect to your PMS, it retries three times before sending us an alert via AWS CloudWatch. In that rare event, no scores are updated, and your staff simply reverts to their manual process for the day. Our optional maintenance plan includes a 4-hour response time for any production issues.
- How is this better than buying a pre-built no-show module?
- Off-the-shelf modules use a generic model trained on data from hundreds of different clinics. Our model is trained exclusively on your patient data. It learns the specific patterns of your practice, such as whether appointments with a certain hygienist are higher risk or if patients from a particular zip code are more likely to no-show. This specificity results in much higher accuracy for your clinic.
- What about patient data and HIPAA compliance?
- We sign a Business Associate Agreement (BAA) before any work begins. All patient data is processed in a secure environment, and the final system is deployed to your own AWS account. This gives you full ownership and control over the data and infrastructure. We do not store any Protected Health Information (PHI) on our systems after the project handoff is complete.
- Does my front desk need special training to use this?
- No. The output is a simple score or color-coded flag that appears directly in your PMS appointment view. The only change to their workflow is that instead of calling everyone, they can focus on the high-risk patients first. We provide a one-page guide explaining what the scores mean and how to use the prioritized list effectively.
- What if we are a new clinic with limited appointment history?
- To build an accurate model, we need at least 12 months of appointment history containing a minimum of 500 no-show instances. For clinics that do not meet this threshold, a model's predictions would not be reliable. We perform a data audit as the first step and will advise if it is better to wait a few months to collect more data before starting the build.
