The iCam Imetric scan is a chairside, non-contact impression technique that utilizes digital photogrammetry to capture a detailed 3D image of the patient’s oral cavity, including the position of dental implants. This scan is particularly beneficial for full-arch implant restorations, as it eliminates the need for traditional impressions, which can be uncomfortable and time-consuming for patients.
Step 1: Preparation
- Cleaning and Drying: The patient’s mouth is thoroughly cleaned and dried to ensure optimal image capture.
- Placement of ICam4D Scan Bodies: Small, standardized ICam4D scan bodies are placed on the implants multi unit abutments. These scan bodies serve as reference points for the photogrammetry process.
Step 2: Scanning
- Handheld Scanner: The iCam4D handheld scanner is used to capture multiple images of the patient’s oral cavity, including the scan bodies and surrounding structures. The scanner emits a structured light pattern that reflects off the scan bodies and creates a series of overlapping images.
- Automatic Image Processing: The images captured by the scanner are automatically processed using advanced computer algorithms. The algorithms extract depth information from the images, resulting in a 3D point cloud representation of the oral cavity.
Step 3: 3D Data Creation
- Mesh Generation: The 3D point cloud is converted into a triangular mesh, which provides a more structured representation of the oral cavity.
- Surface Reconstruction: The mesh is further processed to create a smooth, continuous surface.
Step 4: Digital Model
- Registration: The 3D data from the intra oral scanner is registered to the patient’s existing dental records. This ensures that the 3D model is accurately aligned with the patient’s anatomy.
- Full-Arch Implant Model: The 3D model is manipulated to create a full-arch implant model, including the position of the implants, gingival contours, and surrounding anatomy.
Step 5: Delivery
- Digital Transfer: The digital implant model is transferred to the dental laboratory, where it serves as the foundation for fabricating the final restoration.
- Design and manufacturing: Following receipt of the data the prosthesis will be designed as your specification.
Overall, the iCam Imetric scan is a valuable tool for full-arch implant restorations, providing a comfortable, efficient, and accurate alternative to traditional impression techniques.
