How to Use Intraoral Scanner

Intraoral scanners have revolutionized the field of dentistry by replacing traditional impression methods with digital scans. An intraoral scanner is a device used by dental professionals to capture direct optical impressions—a mouthful, quite literally! The scanner allows for a precise and comfortable way to create digital models of teeth. This guide is intended for dentists, orthodontists, prosthodontists, and dental hygienists who want to understand the operational details of intraoral scanners. We'll explore the steps for using this technology effectively and consider tips and reminders along the way.

Terms Explanation

Intraoral Scanner: This is a device used in dentistry to capture 3D images of the inside of a patient's mouth. These images are used for designing crowns, bridges, braces, implants, and other dental restorations.

CAD/CAM: Computer-Aided Design/Computer-Aided Manufacturing. These technologies work in tandem with intraoral scanners to create precise dental restorations.

Task Step Guide

1. Setting Up the Scanner

Before using the intraoral scanner, ensure it is properly set up.

• Check Hardware: Ensure that the scanner and its computer are connected and powered up.

• Software Configuration: Open the scanning software and ensure it is up-to-date.

• Calibrate: Some scanners need to be calibrated before use to ensure accuracy.

2. Preparing the Patient

Proper preparation of the patient is crucial for an accurate and comfortable scan.

• Explain the Procedure: Inform the patient about the process and why it's being done.

• Positioning: Place the patient in a comfortable yet accessible position.

• Dryness: Ensure the scanning area is dry. Use air or suction to remove any saliva.

3. Scanning Procedure

This is the core activity where the scanner captures the digital impression.

• Start with Occlusal Surfaces: Begin with the biting surfaces as they provide a stable base.

• Move to Other Surfaces: Gradually scan the buccal (cheek) side and lingual (tongue) side.

• Steady Hands: Keep a steady hand to avoid blurry scans.

• Use Markers: Use natural markers like existing fillings to ensure alignment.

4. Reviewing the Scan

After scanning, review the digital impression to ensure it is accurate and free from errors.

• Detailed View: Use the software's zoom and rotate features to inspect the digital model closely.

• Identify Errors: Look for missing data, holes, or distortions.

• Rescan: If necessary, rescan questionable areas to capture missing details.

5. Post-Scanning

Once you have a satisfactory scan, the next steps are essential for making the scanned data useful.

• Save and Export: Save the scan and export it to the desired format compatible with CAD/CAM systems.

• Send to Lab: If a physical model is needed, send the scan to a dental lab.

• Patient Records: Keep a backup for patient records and future reference.

Tips and Reminders

• Maintenance: Regularly clean and maintain the scanner to ensure longevity and accuracy.

• Training: Stay updated with the latest advancements and periodic training sessions.

• Patient Comfort: Always keep patient comfort in mind to reduce anxiety and movement during the scan.

Intraoral scanners are a transformative technology in the field of dental medicine. Understanding how to efficiently use them ensures accurate, fast, and comfortable dental impressions. By following the step-by-step guide, dental professionals can leverage the full potential of this innovative technology, ultimately enhancing patient care and streamlining workflows. Remember to stay informed about your device's specifics and regularly update both software and skills for optimal performance.
