Digital Onlays and Inlays

Onlays and inlays are types of dental restorations used to repair damaged or decayed teeth. In exocad software, these procedures can be performed efficiently and precisely. Here is a step-by-step guide on how onlays and inlays are digitally designed in exocad:

1. Model Scanning:
   Intraoral Scanning: First, the patient's teeth are scanned using an intraoral scanner to create a 3D digital model of the mouth.
   Scanning of Plaster Models: Alternatively, if physical plaster models are available, they can be scanned using a tabletop scanner.

2. Importing Scanned Files:
   The scanned files are imported into exocad. The software accepts common scan file formats such as STL, PLY, or OBJ.

3. Model Preparation:
   Trimming and Alignment: The digitized models are correctly aligned in the software, and any unwanted areas are trimmed.
   Margin Definition: Margins and boundaries of the areas to be restored are defined with precision.

4. Planning and Design:
   Cavity Definition: The area of the cavity to be restored is identified and marked on the digital model.
   Tooth Library: Using exocad's tooth library, the appropriate shape and size for the restoration are selected.
   Positioning: The restoration (onlay or inlay) is positioned on the digital model, adjusting height, inclination, and other anatomical features to suit the patient's case.
   Fine Adjustments: Fine adjustments are made to ensure correct occlusion, aesthetics, and functionality. Exocad provides tools to adjust proximal and occlusal contacts.

5. Analysis and Approval:
   3D Visualization: The digital onlay or inlay can be viewed in 3D, allowing the dentist and the patient to see how the final result will look.
   Occlusion Simulation: The software allows occlusion simulation to check for interferences or undesirable contacts.
   Final Adjustments: Any necessary adjustments can be made at this stage to perfect the design.

6. Generating Production Files:
   Export: Once the design is approved, the final model is exported in STL or another compatible format for production.
   Manufacturing: The exported files can be used for milling or 3D printing the restoration, using materials such as ceramic or composite resin.

Benefits of Digital Onlays and Inlays in exocad:
Precision and Efficiency: Using exocad ensures precision and saves time in planning and executing restorations.
Visualization and Communication: It facilitates communication between the lab, dentist, and patient, allowing for adjustments and approvals before final production.
Customization: It allows the customization of each case, considering the patient's individual anatomy and needs.

Conclusion:
The digital design of onlays and inlays in exocad is a modern approach that provides precise aesthetic and functional results, ensuring patient satisfaction and efficiency in the dental restoration process.
