Intraoral Scanning by Oral Scanner

• Accuracy and Precision: Intraoral scanners produce highly accurate and detailed 3D images of the dental structures, which can improve the fit and function of dental restorations like crowns, bridges, and aligners.
• Comfort and Convenience: Compared to traditional impression methods that involve dental putty, intraoral scanning is more comfortable for patients, particularly those who might experience gag reflex or discomfort with traditional impressions.
• Time Efficiency: The digital workflow reduces the time required for impression taking and allows for faster turnaround times from dental laboratories since digital models can be sent electronically.
• Visualization and Education: The immediate visualization of the digital impression on a screen allows dentists to discuss dental issues and treatment plans more effectively with patients.
• Reduced Environmental Impact: Digital impressions eliminate the need for disposable impression materials and plastic trays, contributing to environmentally friendly dental practices.

How It Works

• Preparation: The dentist prepares the patient’s mouth by removing any debris or obstructions and may apply a powder or spray in some cases to optimize the optical properties of the teeth and soft tissues for scanning.
• Scanning Process: The dentist or dental hygienist moves the intraoral scanner’s wand around the patient’s mouth. The wand emits a light (often laser or structured light) to capture the surfaces of the teeth and gums from various angles. The process is painless and typically takes a few minutes to complete, depending on the area being scanned.
• Data Processing: As the scanner captures the images, software processes the data in real-time, stitching the images together to create a detailed 3D model of the mouth. This model is displayed on a computer screen for immediate review.
• Digital Impression Use: The digital model can be used for various diagnostic and treatment planning purposes, including the design and fabrication of orthodontic appliances, dental restorations (e.g., inlays, onlays, crowns, bridges), and surgical guides for implant placement.

Types of Intraoral Scanners

There are several brands and models of intraoral scanners available, each with unique features and capabilities. While some are standalone devices, others are part of a larger digital dentistry ecosystem, integrating with software for CAD (Computer-Aided Design) and CAM (Computer-Aided Manufacturing), 3D printers, and milling machines for a complete in-office fabrication workflow.

Considerations

• Cost and Investment: The initial investment in intraoral scanning technology can be significant, but the efficiency, accuracy, and patient satisfaction can offset the costs over time.
• Learning Curve: There is a learning curve associated with mastering the use of intraoral scanners and integrating them into the dental practice’s workflow.
• Compatibility: It’s important to ensure that the intraoral scanner is compatible with other digital dentistry systems and workflows, including laboratory processes and software applications used for restorative or orthodontic work.
