Right panel shows a lower jaw (mandible) diagram with a similar continuous scanning path indicated by arrows. **3Shape scan strategy** Maxilla The recommended scanning path consists of three swipes: occlusal, buccal, and palate. 1. Start the scanner while it rests occlusal on the molar, wait 3-5 clicks. 2. Move towards the centrals, capturing the occlusal surface. 3. Continue slowly during the centrals and again continue along the occlusal surface until you reach the last molar. 4. Turn slowly buccal by rotating the scanner 60-90 degrees at the last molar and complete the buccal swipe taking care of areas where soft tissue may interfere with the scan. 5. Go along the buccal side until reach the last molar on the opposite side. 6. Then roll to the palate side and complete the swipe. If you wish to include the palate in the scan, swipe back to position the scanner behind the incisors and then slowly go from side to side the palate in the distal direction.  #### Maxillary Scanning Path The recommended scanning path for the maxilla consists of three swipes: occlusal, buccal, and palate. 1. Start the scanner while it rests occlusal on the molar; wait 3-5 clicks. 2. Move towards the centrals, capturing the occlusal surface. 3. Continue slowly during the centrals and again continue along the occlusal surface until you reach the last molar. 4. Turn slowly buccal by rotating the scanner 60-90 degrees at the last molar and complete the buccal swipe, taking care of areas where soft tissue may interfere with the scan. 5. Go along the buccal side until you reach the last molar on the opposite side. 6. Roll to the palate side and complete the swipe. #### Palatal Coverage If you wish to include the palate in the scan, swipe back to position the scanner behind the incisors and then slowly go from side to side across the palate in the distal direction. Labeled diagram illustrating the 'Maxilla' scanning path. The visual depicts an upper dental arch with a blue line tracing a specific sequence of movements: starting at the molar (occlusal), moving across centrals, turning buccally to the opposite side, and finally rolling to the palate. --- Click to insert 2026-01-15 # 3Shape scan strategy **Mandible** Lower Scan: The recommended scanning path consists of 3 sweeps: Occlusal, lingual, and buccal. The best scanning method is to start with the molar occlusal surface. 1. Wait 3-5 clicks, then move towards the incisors. 2. Slowly wiggle the scanner when passing centrals. 3. Continue until the last molar. Remember to move the scanner smoothly without jumping around. 4. When you reach the last molar, turn slowly lingual, taking care of areas where soft tissue may interfere with the scan. 5. Roll the scanner 60-90 degrees to the lingual side and use the tip to keep the tongue away. 6. Go along the lingual surface of the whole arch, until reach the last molar on the opposite side. 7. Roll to the buccal side and complete the buccal swipe. 8. Go along the buccal surface of the whole arch. 54  #### Mandibular Scanning Path The recommended scanning path for the lower arch consists of three sweeps: occlusal, lingual, and buccal. The best scanning method is to start with the molar occlusal surface. 1. Wait 3-5 clicks, then move towards the incisors. 2. Slowly wiggle the scanner when passing centrals. 3. Continue until the last molar. Ensure the scanner moves smoothly without jumping around. 4. When you reach the last molar, turn slowly lingual, taking care of areas where soft tissue may interfere with the scan. 5. Roll the scanner 60-90 degrees to the lingual side and use the tip to keep the tongue away. 6. Go along the lingual surface of the whole arch until you reach the last molar on the opposite side. 7. Roll to the buccal side and complete the buccal swipe. 8. Go along the buccal surface of the whole arch. Diagram illustrating the 'Mandible' scanning path for a 3Shape scanner. The image shows a U-shaped mandibular arch with teeth represented as gray ovals. A blue line traces the recommended 3-sweep path: starting at the molar occlusal surface, moving towards incisors, turning lingual to scan the inner surface of the arch, and finally rolling to the buccal side to complete the swipe. An arrow indicates the direction of movement.

The left image displays an upper maxillary denture with pink acrylic base and artificial teeth. The right image shows a lower mandibular denture with similar construction. These images serve to demonstrate or compare complete denture designs.  Clinical close-up photograph of a mucosal surface, likely oral cavity or pharynx.

The image demonstrates the texture and morphology of the internal structure.  Clinical photo: Close-up view of a mucosal surface (likely oral cavity or similar tissue) showing pinkish-red tissue with white patches, possibly indicating candidiasis or another lesion. digital workflow  Digital workflow Composite figure illustrating a 'digital workflow'. The image displays two pieces of medical or dental equipment on a dark background with the title 'digital workflow' in the center. On the left is a machine with an amber/orange translucent top housing a lattice-like internal structure and a control panel at the bottom. On the right is a larger white machine labeled 'ivoclar', featuring a digital display screen showing colorful icons. This visual demonstrates the hardware components involved in the digital process.

The image shows an occlusal view of upper and lower teeth with pink gingival tissue surrounding them. The upper arch features prominent anterior teeth (incisors) that appear slightly translucent or have a distinct surface texture compared to the posterior teeth. The lower arch also displays a full set of teeth with varying degrees of translucency and coloration. The interface includes a blue title bar at the top, a vertical toolbar on the right side, and the '3shape' logo in the bottom right corner. **STL** **Standard Tessellation Language** **PLY** **Polygon File Format** STL | PLY 2026-01-15 63  #### Common Digital File Types - **STL**: Standard Tessellation Language - **PLY**: Polygon File Format Comparative figure displaying two 3D dental models side-by-side against a black background. The left model is rendered in grayscale (white) and labeled 'STL' with the definition 'Standard Tessellation Language' below it. This model shows teeth without soft tissue or color. The right model is rendered in full color, featuring pink gums and colored tooth structures, labeled 'PLY' with the definition 'Polygon File Format' below it. A header bar at the top reads 'STL | PLY'. The visual demonstrates the difference between STL (geometry only) and PLY (geometry plus material/color properties). <strong>Click to insert</strong> 2026-01-15 **Laboratory workflow** **Laboratory workflow** 64   #### Laboratory Workflow Click to insert Photo of a laboratory device with an orange illuminated chamber containing a lattice structure, labeled 'Benchtop X' and featuring a circular logo.
