CAD/CAM in Dentistry: Get Precision Restorations in One Visit

CAD/CAM in dentistry uses computer-aided design and manufacturing to create high-precision dental restorations like crowns, veneers, and bridges. By utilizing digital scanning and on-site milling, dentists can often complete complex restorative procedures in a single appointment, offering a faster and more comfortable alternative to traditional laboratory methods through cerec dentistry.

Understanding the CAD/CAM Workflow

The digital dentistry process replaces manual impressions and external lab work with a streamlined digital sequence:

1. Tooth Preparation: The dentist removes decay or damaged tooth structure to prepare the site for the restoration.
2. Intraoral Scanning: A specialized optical scanner captures a 3D digital impression of the prepared tooth and surrounding anatomy.
3. Restoration Design: CAD software allows the dentist to design the final restoration with precise anatomical detail.
4. Milling: An in-office milling machine carves the restoration from a high-strength ceramic block based on the digital design.
5. Sintering and Polishing: The restoration is stained, glazed, and polished to match the natural appearance of your teeth.
6. Cementation: The finished piece is permanently bonded to the tooth.

Depending on the complexity of the case, this process typically takes between 45 minutes and two hours.

Key Advantages of CAD/CAM Technology

• Single-Visit Convenience: Eliminates the need for temporary crowns and multiple office visits.
• Improved Comfort: Replaces traditional, uncomfortable alginate impression trays with quick, non-invasive digital scanning.
• Enhanced Precision: Digital workflows reduce the potential for human error associated with manual impressions.
• Cost-Effectiveness: By reducing outsourcing to external laboratories, some practices can offer more competitive pricing.

Is CAD/CAM Right for You?

While CAD/CAM is highly effective for many patients, it may not be suitable for every situation. For certain complex fabrications, a practitioner might still recommend traditional laboratory methods to ensure the best possible fit and structural integrity. Consult with your dentist to determine if your specific dental crowns and bridges needs can be addressed with this technology.

Frequently Asked Questions

Is CAD/CAM dentistry more accurate than traditional methods?

Yes, digital scanning minimizes the distortion risks inherent in traditional impression teeth materials, often leading to a more precise fit for your restoration.

How long does a CAD/CAM restoration last?

With proper oral hygiene and regular dental checkups, CAD/CAM restorations are as durable and long-lasting as those created in a traditional dental laboratory.

Are all dental restorations made with CAD/CAM?

Not necessarily. While versatile, some complex cases or specific bridge designs may require traditional laboratory fabrication. Your dentist will evaluate your unique clinical needs to recommend the best approach.

Does CAD/CAM cost more?

Costs vary by practice. Because CAD/CAM technology can reduce outsourcing expenses, some of these savings may be passed on to the patient. It is best to discuss your treatment options and associated costs during your next crown appointment with your dental provider.
