Introduction: Why CAD/CAM Integration Matters in Digital Dentistry

Modern dentistry is moving from traditional impressions and manual production toward a connected digital workflow.

Instead of taking a physical impression, sending it to a laboratory, waiting for a plaster model, and manually producing the final appliance, clinics and dental laboratories can now connect digital scanning, CAD design, and 3D printing into one workflow.

A typical digital dental workflow can be summarized as:

Scan → Design → Prepare → Print → Post-Process → Deliver

Aident3D is designed around this digital workflow, combining intraoral scanning, dental laboratory scanning, CAD/CAM compatibility, dental 3D printing, and dental 3D printing materials.

For clinics and dental laboratories considering CAD/CAM integration, the key question is not simply which scanner or printer to purchase.

The more important question is:

How well can the equipment work together as a complete digital workflow?

This guide explains how to integrate Aident equipment with CAD/CAM software and how to build an efficient digital dentistry workflow.

1. What Is a Dental CAD/CAM Workflow?

CAD/CAM stands for Computer-Aided Design and Computer-Aided Manufacturing.

In dentistry, CAD/CAM technology allows patient or model data to be digitally captured, designed, modified, and manufactured.

A basic workflow consists of three major stages:

1. Data Acquisition

The patient's oral anatomy is captured using an intraoral scanner.

For laboratory workflows, a dental lab scanner can digitize physical models, impressions, or other dental objects.

2. CAD Design

The digital scan data is imported into dental CAD software.

The technician or dentist can then design:

Crowns

Bridges

Implant restorations

Surgical guides

Denture components

Orthodontic models

Temporary restorations

Clear aligner models

Diagnostic models

3. CAM Manufacturing

After the design is completed, the digital file is transferred to a manufacturing device.

Depending on the application, the final product can be produced through milling, 3D printing, or another manufacturing process.

For resin-based dental applications, a dental 3D printer provides a direct path from digital design to physical production.

2. How Aident Fits Into the CAD/CAM Workflow

Aident's digital workflow can be understood as:

Aident Scanner → CAD Software → Aident Dental 3D Printer → Dental Resin → Finished Product

The scanner captures the digital information.

CAD software processes and designs the case.

The dental 3D printer manufactures the physical model or appliance.

The resin determines the material properties required for the specific application.

This creates a connected workflow instead of treating each device as an isolated piece of equipment.

Aident currently provides intraoral scanners, dental lab scanners, dental 3D printers, dental resins, and related digital dentistry solutions.

3. Step 1: Capture Digital Data with the Aident AI-30

The first step is acquiring accurate digital data.

The Aident AI-30 Intraoral Scanner is designed for digital impression workflows and can export digital scan data for downstream CAD/CAM processing.

Aident's published workflow documentation describes the AI-30 as supporting high-accuracy scanning and compatibility with major dental software platforms such as 3Shape and exocad.

The basic scanning workflow is:

Prepare the patient's mouth.

Start the intraoral scanning software.

Scan the teeth systematically.

Capture the full arch.

Record the opposing arch.

Capture the buccal bite relationship.

Check the scan for missing areas and artifacts.

Complete the digital impression.

Export the required digital file.

Recommended scanning check

Before moving to CAD design, always check:

Are all required teeth captured?

Are the preparation margins visible?

Is the occlusion complete?

Are there holes or missing areas?

Is there excessive soft-tissue data?

Is the scan free from obvious distortion?

Is the bite relationship correct?

A good CAD/CAM workflow starts with good digital data.

If the scan is incomplete or inaccurate, CAD software cannot completely correct the problem later.

4. Step 2: Export the Scan Data

Once scanning is completed, export the digital case into a format supported by your CAD/CAM workflow.

Common dental digital formats include:

STL

PLY

OBJ

STL is particularly common for CAD and 3D printing because it represents the surface geometry of the scanned object.

Aident's published integration guidance identifies STL as one of the most widely used formats for transferring intraoral scan data into CAD/CAM and 3D printing workflows.

Depending on your scanner software and CAD system, additional formats may be available.

Practical recommendation

Before purchasing equipment, confirm:

Scanner → File Format → CAD Software → CAM/Printer

The most important factor is not simply whether two devices have the same brand.

The key is whether the digital data can move smoothly between them.

5. Step 3: Import Aident Scan Data into CAD Software

After exporting the scan, open your preferred dental CAD software.

Aident's digital workflow is designed around an open workflow rather than requiring users to remain inside a proprietary ecosystem.

Aident documentation references compatibility with platforms including:

3Shape

exocad

Other CAD/CAM applications supporting standard dental file formats

The general workflow is:

Open CAD Software → Create New Case → Import Scan → Define Patient/Case Data → Start Design

Depending on the application, you may need to import:

Upper arch

Lower arch

Bite scan

Preparation scan

Implant scan

Gingiva data

Additional reference data

6. Step 4: Design the Dental Restoration or Model

After importing the scan, the CAD software becomes the main design environment.

For example, a crown workflow may include:

Define the preparation.

Mark the margin.

Select the restoration type.

Set insertion direction.

Adjust the restoration parameters.

Design the anatomy.

Check proximal contacts.

Check occlusion.

Inspect minimum thickness.

Complete the final design.

For orthodontic applications, the workflow can be different.

The technician may instead:

Import the digital model.

Segment the teeth.

Define the treatment plan.

Generate individual stages.

Create the corresponding dental models.

Export the models for 3D printing.

The same digital scanning infrastructure can therefore support multiple clinical and laboratory applications.

7. Step 5: Prepare the CAD File for 3D Printing

After the CAD design is completed, export the final model.

A typical workflow is:

CAD Design → Export STL → Import into Slicing Software → Orient Model → Add Supports → Slice → Send to Printer

Before printing, review the model carefully.

Check the following:

Model orientation

Choose an orientation that balances surface quality, support requirements, printing time, and material consumption.

Support placement

Avoid unnecessary supports on critical surfaces whenever possible.

Wall thickness

Make sure the designed structure meets the requirements of the selected application and material.

Print area

Check whether multiple models can be arranged efficiently on the build platform.

File integrity

Make sure the STL or other digital file is complete and free from obvious mesh errors.

8. Step 6: Print with an Aident Dental 3D Printer

Once the digital file is prepared, it can be transferred to an Aident dental 3D printer.

Aident provides dental 3D printing systems designed for applications including:

Dental models

Surgical guides

Clear aligner models

Denture-related applications

Temporary restorations

Diagnostic models

Other dental applications

Aident's current product and workflow materials position models such as the Ai-C60 and Ai220 within its digital dental production ecosystem.

The general manufacturing workflow is:

STL → Slicer → Printer → Wash → Cure → Finish

The correct printer and resin should be selected according to the intended application.

9. Step 7: Choose the Right Dental Resin

CAD/CAM integration does not end with the printer.

Material selection is equally important.

Different dental applications require different materials.

For example:

Aident provides dedicated dental resins intended to work with dental 3D printing workflows.

The correct combination should always be selected according to the intended clinical or laboratory application and the manufacturer's validated workflow.

10. Complete Aident CAD/CAM Workflow

The complete digital workflow can therefore be summarized as follows:

Clinic Workflow

Patient

↓

Aident AI-30 Intraoral Scanner

↓

Digital Scan Data

↓

3Shape / exocad / Compatible CAD Software

↓

Digital Design

↓

STL Export

↓

Aident Dental 3D Printer

↓

Dental Resin

↓

Post-Processing

↓

Finished Dental Model or Appliance

This workflow removes many physical steps from the traditional process.

Instead of:

Physical Impression → Shipping → Plaster Model → Manual Processing → Production

the digital workflow becomes:

Scan → Design → Print

Aident itself describes its digital solution using the Scan → Design → Print concept.

11. Aident + 3Shape Workflow

For dental laboratories already using 3Shape, the workflow can be structured as:

Aident AI-30 / Lab Scanner

→

3Shape

→

Dental CAD Design

→

Export STL

→

Aident 3D Printer

→

Post-Processing

The major advantage is that the scanner does not have to be replaced simply because the laboratory uses another CAD platform.

The open digital workflow allows the data to move between different parts of the production chain.

12. Aident + exocad Workflow

The same concept can be applied to exocad.

Workflow

Aident Scanner

→

Scan Data

→

exocad

→

CAD Design

→

STL

→

Aident Slicing / Printing Workflow

→

Dental 3D Printer

This can be particularly useful for laboratories that already have an established exocad workflow.

The goal is not to change the entire digital ecosystem.

Instead, Aident equipment can become part of the existing workflow.

13. How to Reduce CAD/CAM Workflow Errors

One of the biggest benefits of digital dentistry is repeatability.

However, a digital workflow can still produce errors if each stage is not checked.

A simple quality-control system should include four checkpoints.

Checkpoint 1: Scan

Confirm:

Complete anatomy

Clear margins

Correct occlusion

No obvious holes

No unnecessary artifacts

Checkpoint 2: CAD

Confirm:

Correct restoration type

Correct margins

Proper contacts

Proper occlusion

Adequate thickness

Checkpoint 3: Print Preparation

Confirm:

Correct orientation

Appropriate supports

Correct printer profile

Correct resin

Correct layer settings

Checkpoint 4: Post-Processing

Confirm:

Complete washing

Correct curing

No visible deformation

Proper surface quality

Dimensional accuracy appropriate for the application

The most effective digital workflow is not simply the fastest workflow.

It is the workflow that minimizes rework and remakes.

14. How CAD/CAM Integration Can Improve Dental Laboratory Efficiency

A well-integrated CAD/CAM workflow can provide several operational advantages.

Faster Data Transfer

Digital scan files can be transferred immediately instead of physically shipping impressions.

Easier Case Storage

Digital patient cases can be stored electronically and accessed when needed.

Easier Communication

Dentists and laboratories can share digital cases without repeatedly transporting physical models.

Faster Design Changes

CAD designs can be modified before manufacturing.

More Flexible Production

The same digital design can potentially be manufactured again when required, subject to the applicable clinical and technical requirements.

Better Production Planning

Dental laboratories can organize multiple digital cases and send them to production according to priority.

Aident's published digital workflow emphasizes the combination of scanning, CAD design, 3D printing, and post-processing as a connected production chain.

15. Common CAD/CAM Integration Problems

Even when every device works correctly, integration problems can occur.

Problem 1: The CAD Software Cannot Open the File

Possible reasons include:

Unsupported file format

Incorrect export settings

Damaged mesh

Software compatibility issues

Solution

Check the scanner's available export formats and confirm that the CAD software supports the selected format.

Problem 2: The CAD Design Looks Correct but the Printed Model Does Not

Possible causes include:

Incorrect print orientation

Incorrect scaling

Poor support placement

Incorrect printer parameters

Resin or post-processing problems

Always verify the digital model and print preparation before production.

Problem 3: The Occlusion Is Incorrect

This may originate from the bite scan rather than the printer.

Check:

Buccal scan

Upper/lower alignment

Bite registration

Missing scan areas

The printer cannot correct incorrect digital occlusion data.

Problem 4: The Workflow Is Too Slow

If the entire process is slow, don't look only at printer speed.

Analyze the complete chain:

Scanning Time + Design Time + Preparation Time + Printing Time + Post-Processing Time

A faster printer does not necessarily create a faster overall workflow if scanning, CAD design, or post-processing remains inefficient.

16. How to Build an Aident Digital Dental Workflow

17. What Should You Check Before Buying a CAD/CAM System?

Before purchasing a digital dental system, evaluate the entire workflow instead of comparing only individual specifications.

1. Scanner Compatibility

Can the scanner export files required by your CAD software?

2. CAD Compatibility

Does your existing CAD software support the scanner's data?

3. Printer Compatibility

Can your printer workflow accept the CAD output?

4. Material Compatibility

Is the required resin available for the intended application?

5. Software Workflow

How many manual steps are required between scanning and printing?

6. Training

Can technicians and dental assistants learn the workflow quickly?

7. Technical Support

Is technical assistance available when workflow problems occur?

8. Total Cost of Ownership

Do not evaluate only the purchase price.

Consider:

Equipment + Software + Materials + Maintenance + Consumables + Labor + Remakes

This gives a much more realistic picture of the cost of digital dentistry.
