The Process

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

  1. Cleaning and Drying: The patient’s mouth is thoroughly cleaned and dried to ensure optimal image capture.
  2. 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

  1. 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.
  2. 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

  1. Mesh Generation: The 3D point cloud is converted into a triangular mesh, which provides a more structured representation of the oral cavity.
  2. Surface Reconstruction: The mesh is further processed to create a smooth, continuous surface.

Step 4: Digital Model

  1. 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.
  2. 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

  1. Digital Transfer: The digital implant model is transferred to the dental laboratory, where it serves as the foundation for fabricating the final restoration.
  2. 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.
