Digital dentistry has brought new levels of accuracy, speed, and efficiency to Canadian dental clinics. From intraoral scanners to CAD/CAM systems, digital workflows reduce chair time and increase patient satisfaction. But even the most advanced tools come with risks—if not used correctly.

At First Dental Studio, we support clinics across Canada with digital case planning and restoration fabrication. Below, we break down six common mistakes we see in digital dentistry—and how to avoid them.

1. Relying on Tech Without Proper Training

Digital tools don’t automatically guarantee perfect results. One of the most common mistakes is assuming that the software or scanner will compensate for inexperience.

Examples of this mistake:

• Intraoral scans with missed margins
• CAD software used on default settings
• Poor prep design due to misunderstanding scanner limitations

What to Do:

• Attend vendor training and certification courses
• Encourage staff to revisit manufacturer tutorials regularly
• Combine digital tools with strong clinical judgment

2. Poor Scanning Technique

Scanners are only as accurate as the technique used. Incomplete scans, missing contact points, and improper retraction can all affect results.

Common scanning issues:

• Stitching errors during full arch scans
• Moisture obscuring margins
• Not scanning distal or buccal surfaces adequately

What to Do:

• Follow the scanner’s scan path protocol
• Use isolation tools to control moisture
• Retract soft tissue effectively around critical areas
• Always review scans before submission to the lab

We offer free scan reviews through our digital case submission portal to help avoid rework.

3. Ignoring Occlusion and Functional Design

Focusing only on aesthetics during digital design can lead to functional problems post-placement.

Issues this causes:

• Premature contacts
• Poor articulation
• Fracture risks or restoration failure

What to Do:

• Use accurate bite registration techniques
• Leverage occlusion simulation tools in CAD software
• Collaborate with labs to adjust functional contacts as needed

Your lab should flag high occlusal spots or improper bite alignment during design. That’s part of what we do at First Dental Studio.

4. Mismanaging Data or File Submissions

Missing files, mislabeled scans, and incomplete impressions are all too common—and they cost time, money, and patient trust.

What to Avoid:

• Uploading the wrong arch
• Forgetting to include opposing scans or bite
• Sending files without naming conventions

What to Do:

• Use a clear naming protocol for STL and PLY files
• Confirm full scan sets before sending
• Double check uploads within your scanner’s cloud or lab portal

5. Not Using Advanced Features in CAD Software

Most CAD software includes tools for margin control, anatomic libraries, and occlusal simulations—but many users stick to default settings.

Why it matters:

• You miss out on case customization
• Restorations may lack ideal contour or contact
• Inlays/onlays and layered ceramics are harder to optimize

What to Do:

• Attend software workshops or webinars
• Experiment with margin control, contact zones, and virtual wax-ups
• Collaborate with your lab on design previews or case simulations

Our team can walk you through advanced features—don’t leave your design potential untapped.

6. Skipping Try-Ins and Post-Processing

Digital dentistry isn’t plug-and-play. Milling or printing a crown doesn’t mean it’s ready for final cementation right away.

Common mistakes:

• Cementing without checking fit or contacts
• Skipping polishing or glazing
• Ignoring occlusal rebalancing before finalization

What to Do:

• Always conduct a clinical try-in
• Adjust contacts and polish the restoration
• Complete post-processing (e.g., sintering, glazing) as required

Let your lab know if you plan to do the finishing—or if you’d prefer it sent ready for cementation.

Make the Most of Digital Dentistry

Digital systems only reach their full potential when used correctly. Avoiding these common mistakes will reduce remakes, save chair time, and improve patient outcomes.

At First Dental Studio, we’re here to help you succeed with digital workflows. Whether you’re scanning a single crown or managing a full-arch digital denture case, we offer support at every step.
