How to Use Intraoral Scanners to Assess Occlusal Contacts Precisely

by

Intraoral scanners have revolutionized the way dental professionals assess occlusal contacts. These advanced devices provide highly accurate, digital impressions of a patient’s teeth, enabling precise evaluation of how the upper and lower teeth come into contact. Proper use of intraoral scanners can improve diagnosis, treatment planning, and patient outcomes.

Understanding Intraoral Scanners

Intraoral scanners are handheld devices that capture detailed 3D images of the dental arches. They replace traditional impression materials, offering a more comfortable experience for patients. The scanners use optical technology to create digital models that can be analyzed for various purposes, including assessing occlusal contacts.

Steps to Assess Occlusal Contacts Using Intraoral Scanners

  • Prepare the patient: Ensure the patient’s mouth is dry and free of debris. Explain the procedure to reduce anxiety.
  • Capture the scans: Slowly move the scanner over the upper and lower arches, ensuring all surfaces are captured accurately. Use the scanner’s software to stitch images into a complete 3D model.
  • Analyze the digital models: Use the software tools to identify contact points. Many scanners allow you to simulate occlusion and highlight areas of contact.
  • Assess occlusal contacts: Check for areas of excessive contact, open contacts, or premature contacts. Adjust the digital model as needed for clarity.
  • Verify with physical or digital adjustments: Use the digital model to guide adjustments in restorations or orthodontic appliances for optimal occlusion.

Tips for Accurate Assessment

  • Ensure the scanner is calibrated regularly for optimal accuracy.
  • Use proper scanning techniques, keeping the scanner steady and at the correct distance from the teeth.
  • Capture multiple angles to avoid missing any critical contact areas.
  • Utilize software features like contact analysis overlays for detailed evaluation.
  • Combine digital assessment with clinical examination for comprehensive diagnosis.

Conclusion

Using intraoral scanners to assess occlusal contacts offers a precise, efficient, and patient-friendly approach. Mastering their use enhances diagnostic accuracy and improves treatment outcomes, making them an invaluable tool in modern dentistry.
