Full Denture Scan (ENG)

Introduction

This tutorial provides a comprehensive guide on scanning strategies for full dentures, as demonstrated in the Medit Academy video. Effective scanning is crucial for creating accurate dental prosthetics. By following these steps, you will learn the proper order and techniques for scanning maxillary and mandibular dentures.

Step 1: Scan the Maxillary Arch

• Position the patient comfortably and ensure a clear view of the maxillary arch.
• Use a dental scanner to capture the anatomy of the maxillary arch.
• Ensure to include key features such as:
  • The gingival margin
  • Palate contour
  • Any existing teeth if applicable
• Check the scan for completeness and clarity before moving on.

Step 2: Scan the Maxillary Denture

• With the maxillary denture ready, place it firmly in the patient's mouth.
• Begin scanning the denture, ensuring to capture:
  • The internal surface of the denture
  • The external surface, including the borders
• Confirm that the scan shows no missing areas or distortion.

Step 3: Scan the Mandibular Arch

• Adjust the patient’s position for easy access to the mandibular arch.
• Use the scanner to capture the anatomy of the mandibular arch thoroughly.
• Focus on:
  • The gingival contour
  • The ridge areas
• Review the scan for accuracy before proceeding.

Step 4: Scan the Mandibular Denture

• Insert the mandibular denture into the patient’s mouth.
• Scan both the internal and external surfaces of the mandibular denture.
• Make sure to capture:
  • The borders of the denture
  • Any unique features or adjustments
• Verify the quality of the scan to ensure it is free from errors.

Step 5: Perform an Occlusal Scan Using the Denture

• Position the patient to allow for an optimal occlusal view.
• With both dentures in place, conduct the occlusal scan.
• Focus on:
  • The relationship between the maxillary and mandibular dentures
  • Any occlusal interferences
• Ensure a clear representation of the occlusal surfaces.

Conclusion

In this tutorial, we covered the essential steps for scanning full dentures, including the order of operations and practical tips to ensure accurate scans. By following these steps—maxillary scan, maxillary denture scan, mandibular scan, mandibular denture scan, and occlusal scan—you will enhance your denture scanning proficiency. For next steps, consider practicing these techniques with various patients to gain confidence and accuracy in your scanning approach.
