Study Notes
Digital Dentistry
Definition
Digital dentistry refers to the use of digital technologies, such as computer-aided design (CAD) and computer-aided manufacturing (CAM), to create dental restorations and prosthetics.
Advantages
- Increased accuracy and precision
- Reduced laboratory costs and turnaround time
- Improved patient comfort and convenience
- Enhanced communication between dentists, labs, and patients
- Ability to store and retrieve digital data for future reference
Digital Impressions
- Intraoral scanners capture 3D images of teeth and oral structures
- Eliminates need for physical impressions
- Accurate and precise impressions in minutes
- Can be sent to labs for fabrication of restorations
CAD/CAM Systems
- Use software to design and manufacture restorations
- Can create crowns, bridges, dentures, and implants
- Milling machines fabricate restorations from ceramic, metal, and composite materials
- Options for chairside or laboratory-based systems
3D Printing in Dentistry
- Used for creating surgical guides, models, and implant prototypes
- Can print in a variety of materials, including resins and metals
- Rapid prototyping allows for quick iteration and refinement of designs
Digital Smile Design
- Uses digital technology to plan and visualize smile makeovers
- Combines 2D and 3D images to create a digital smile design
- Enhances patient communication and understanding of treatment plans
Limitations and Challenges
- High initial investment in equipment and training
- Limited availability of digital dentistry training and education
- Integration with existing dental practice management systems can be challenging
- Potential for technical difficulties and errors in digital impressions and designs

- Popular CAD software providers include 3Shape, Exocad, and Dental Wings
CAM Fabrication Technologies
Methods and Providers
- Milling machines fabricate restorations from ceramic or composite blocks
- 3D printing uses additive manufacturing technology to fabricate restorations
- Popular CAM machine providers include Sirona Cerec, 3M Lava, and Roland DWX
Indications for CAD/CAM
- Suitable for crowns, bridges, and implant restorations
- Used for inlays, onlays, and veneers
- Applies to dentures and partial dentures
- Used for orthodontic and surgical guides
Limitations of CAD/CAM
- Limited to certain materials and restorations
- Requires training and expertise for operators
- High initial investment in equipment and software
Future of CAD/CAM
- Expected integration with artificial intelligence and machine learning
- Expansion of material options and indications
- Increase in adoption in general dentistry and specialized practices
3D Printing in Digital Dentistry
Definition and Principle
- 3D printing is a type of additive manufacturing that creates physical objects from digital designs
- It is used in digital dentistry to create dental models, surgical guides, and restorations
Types of 3D Printing Technologies
- Stereolithography (SLA) uses a laser to solidify liquid resin
- Digital Light Processing (DLP) uses a light projector to solidify liquid resin
- Fused Deposition Modeling (FDM) uses melted plastic to create objects layer by layer
- Selective Laser Sintering (SLS) uses a laser to fuse together particles of a powdered material
Applications in Digital Dentistry
- Dental models are used for diagnosis, treatment planning, and fabrication of dental restorations
- Surgical guides are used for precise implant placement and oral surgery
- Dental restorations include crowns, bridges, and dentures
- Orthodontic models are used for treatment planning and fabrication of orthodontic appliances
Advantages
- 3D printing allows for high accuracy and precision in dental restorations and models
- It reduces labor time and increases productivity in dental laboratories
- It enables customization of dental restorations and models to individual patient needs
- It reduces material waste and can be more cost-effective than traditional manufacturing methods
Challenges and Limitations
- 3D printed materials may not have the same strength and durability as traditionally manufactured materials
- 3D printed dental restorations and models may require regulatory approval before use in clinical practice
- Dentists and dental technicians may require training and education in 3D printing technology and design software
