6 Common Mistakes To Avoid When Using Icam Photogrammetry

As dental practices continue to adopt digital technologies, dental photogrammetry has emerged as a groundbreaking tool, especially for implantology and full-arch restorations. Among the leading systems is iCAM photogrammetry, known for its precision, speed, and radiation-free imaging capabilities.

However, like any advanced technology, success with dental photogrammetry depends not just on the hardware, but on how well it's used. Improper technique or workflow errors can compromise data quality, leading to poor outcomes and patient dissatisfaction. To help dental professionals get the most from their investment, here are six common mistakes to avoid when using iCAM dental photogrammetry.

1. Incorrect Positioning of Scan Bodies

One of the most frequent mistakes when using iCAM dental photogrammetry is incorrect placement or seating of scan bodies. Scan bodies are temporary markers attached to implants that allow the photogrammetry system to detect and record their exact spatial position.

If scan bodies are not fully seated, are cross-threaded, or not tightened according to manufacturer specifications, the resulting data will be inaccurate. Even minor misalignments can lead to prosthetic fit issues and occlusal imbalances.

Tip: Always verify scan body fit visually and tactilely. Use a torque wrench if required and follow the system’s instructions for handling different implant platforms.

2. Poor Lighting and Environmental Conditions

iCAM dental photogrammetry relies on capturing high-resolution images under controlled lighting. If the room is too bright, has shadows, or contains reflective surfaces, it can interfere with the cameras’ ability to capture clean, accurate images.

Poor lighting can also create image distortion, especially around metallic components, leading to errors in 3D model construction.

Tip: Use the photogrammetry system in a dedicated space with consistent, diffuse lighting. Avoid strong overhead lights or sunlight near the scanner.

3. Improper Camera Calibration or Setup

Before capturing data, iCAM systems require calibration to ensure optimal performance. Failing to perform this calibration, or incorrectly setting up the cameras and tripod, can result in skewed or incomplete data. This often happens when clinics rush through the setup process or reuse previous settings without checking.

Misaligned cameras can distort spatial relationships between scan bodies, reducing the accuracy of the final 3D model.

Tip: Follow the calibration protocol every time the system is moved, or at least daily, to maintain optimal imaging quality. Ensure the tripod is stable, and all cameras are aimed correctly.

4. Insufficient Image Capture or Poor Angulation

A successful photogrammetric scan relies on capturing enough images from multiple angles. Some users mistakenly take too few images or fail to follow the correct image capture pattern, which can result in incomplete or inaccurate models.

In particular, skipping required image angles (such as top-down or lateral views) may cause the software to miscalculate distances or fail to align the scan bodies correctly.

Tip: Follow the recommended scanning sequence. iCAM typically suggests capturing 10–12 images from specified angles to ensure a comprehensive and accurate 3D reconstruction.

5. Ignoring Software Verification Warnings

Once the images are captured, iCAM’s software performs data processing and validation. If the software flags warnings or errors—such as unrecognized scan bodies, poor image quality, or alignment issues—ignoring these prompts can lead to major problems down the line.

Some users proceed despite these alerts, assuming the issue won’t affect the final result, only to discover that the restoration doesn’t fit properly.

Tip: Always review software notifications carefully. If a scan body is flagged or data seems inconsistent, re-capture the required images rather than risking a failed prosthetic fit.

6. Failing to Train the Dental Team Properly

Dental photogrammetry systems like iCAM require precision and consistency in use. Delegating scans to untrained staff or skipping formal training sessions can increase the risk of errors. Mistakes in data capture, scan body handling, or software usage can compromise clinical results—even when the equipment is functioning perfectly.

Tip: Invest in thorough, hands-on training for all team members involved in the digital workflow. Many iCAM providers offer onboarding support, videos, and refresher courses—take advantage of these resources.

Bonus: Skipping Quality Control Before Sending to the Lab

Once a scan is complete, many clinics rush to export the file to the lab. However, skipping final checks for data integrity, scan body visibility, or file compatibility can lead to costly delays and remakes.

Tip: Before exporting or submitting the file, inspect the 3D model closely for anomalies, missing data, or artifacts. Communicate clearly with your dental lab to ensure file formats and expectations align.

Final Thoughts

iCAM dental photogrammetry offers remarkable advantages—exceptional accuracy, radiation-free imaging, and seamless integration with CAD/CAM systems. However, the precision it promises depends on proper usage. By avoiding the six common mistakes listed above, dental professionals can significantly enhance the quality of their digital impressions and ensure better prosthetic outcomes for their patients.

Like any powerful tool, success with dental photogrammetry comes down to consistency, attention to detail, and continuous learning. When used correctly, iCAM photogrammetry doesn’t just match traditional methods—it surpasses them, setting a new standard for digital dentistry.
