In addition to physical and technical preparations, mental preparation is equally important. Visualize the scanning sequence and anticipate potential challenges. Plan your scanning strategy to ensure comprehensive coverage of all relevant areas. Keep in mind the specific anatomical landmarks that need to be captured accurately, such as the gingival margins, occlusal surfaces, and interproximal contacts. A well-thought-out plan not only saves time but also reduces the likelihood of needing to rescan areas. By meticulously preparing both the patient and the equipment, you set the stage for a successful and efficient Cerec Omnicam scanning procedure, leading to more accurate and predictable outcomes.

Mastering the Scanning Technique

The core of using the Cerec Omnicam lies in the scanning technique. Start with the occlusal surface. Hold the Omnicam steady and move it smoothly along the occlusal plane, ensuring you capture all the cusps and grooves. Maintain a consistent distance from the teeth, usually a few millimeters, to keep the image in focus. Next, move to the buccal and lingual surfaces. Angle the Omnicam to capture the facial and lingual aspects of the teeth, overlapping each pass to ensure complete coverage. Pay special attention to the gingival margins, as these are crucial for accurate restoration fit. Don't rush! A slow, steady pace allows the Omnicam to capture more data points, resulting in a more detailed and accurate model.

Effective scanning technique also involves adapting to different clinical scenarios. For example, when scanning edentulous areas, focus on capturing the soft tissue landmarks and ridge contours accurately.
