An Interactive Guide for Young Dentists
As a young dentist entering the world of digital dentistry, you're embarking on an exciting journey that's transforming the profession. 3D scanning and printing technologies have revolutionized dental workflows, improving precision, efficiency, and patient experience.
Digital workflows offer unprecedented accuracy in dental procedures, reducing errors and improving outcomes.
Digital technologies streamline workflows, saving time for both practitioners and patients.
Digital impressions eliminate the discomfort of traditional impression materials, improving patient satisfaction.
3D scanning is the process of analyzing real-world objects to collect data on their shape and appearance. This data is then used to construct digital 3D models. In dentistry, this technology allows for highly accurate digital impressions that can replace traditional physical impressions.
The basic principle involves projecting light patterns or laser beams onto an object and measuring how they're reflected back. Different technologies use various methods to capture this information, but all aim to create precise digital representations of physical structures.
Key scanning technologies include:
Intraoral scanners are handheld devices that capture direct optical impressions of the oral cavity. They've become increasingly popular due to their accuracy, efficiency, and patient comfort compared to conventional impression materials.
Modern intraoral scanners use technologies like confocal microscopy, optical coherence tomography, or triangulation to capture thousands of images per second, creating detailed 3D models of teeth and surrounding tissues. These digital impressions can be immediately assessed for quality and used for various applications including restorations, orthodontics, and implant planning.
Popular intraoral scanning systems include:
Extraoral scanning includes technologies like cone beam computed tomography (CBCT) and facial scanning. CBCT provides detailed 3D images of bone structures, teeth, nerve pathways, and soft tissues, which are invaluable for implant planning, orthodontic assessments, and diagnosing complex conditions.
Facial scanning captures the external features of a patient's face, allowing for aesthetic planning and helping patients visualize potential outcomes of dental treatments. This technology is particularly useful in prosthodontics and orthodontics where facial aesthetics play a crucial role.
Key applications of extraoral scanning include:

Once you have digital models from 3D scanning, 3D printing allows you to create physical objects from these digital files. In dentistry, this technology is used to produce surgical guides, models, temporary restorations, clear aligners, and even permanent prosthetics.
Uses a laser to cure liquid resin layer by layer. Offers high precision for detailed models and surgical guides.
Similar to SLA but uses a digital projector screen. Faster than SLA but may have slightly lower resolution.
Uses a laser to sinter powdered material. Can create metal frameworks and restorations.
Deposits droplets of material that are then cured. Can produce multi-material and multi-color objects.
3D printed surgical guides provide precise positioning for dental implants, ensuring optimal placement based on the digital treatment plan. These guides incorporate information from CBCT scans about bone density, nerve locations, and ideal prosthetic positioning.
Benefits include:
3D printed models serve various purposes in dental practice, from treatment planning to appliance fabrication. They can be printed with different materials depending on the application.
Types of dental models include:
The clear aligner workflow combines 3D scanning and printing technologies. After capturing digital impressions, a series of models representing progressive tooth movements are printed. These models are then used to thermoform clear aligners.
The process typically involves:
Advances in 3D printing materials have enabled the production of both temporary and permanent dental restorations. These range from single crowns to full dentures.
