3D Dental Scanner & CAD/CAM Software Change the Game in Dentistry

CAD/CAM dentistry was a game-changer in the field of dentistry. Restorations, models, abutments, and other oral devices may now be correctly scanned and manufactured, as well as implant and orthodontic designing using CAD/CAM. CAD/CAM systems’ precision, adaptability, and reliability, as well as their ease of use, portability, and affordability, are all factors to consider. Furthermore, different types of scanners, as well as the programs that support digital impressions and CAD/CAM, have varied characteristics. In aesthetic dentistry, CAD/CAM has been shown to provide aesthetic and long-lasting treatments.

For laboratories and dental offices, CAD/CAM has significantly changed the game by improving revenue, lowering treatment times, and providing better care. However, incorporating digital technology into a dentist’s daily routine necessitates the dentist’s dedication to mastering imaging equipment and software.

Process of CAD/CAM Technology

An intraoral impression scanner is typically used to begin the CAD/CAM process at a dental clinic. The majority of them work in the same way, with a little piece of imaging gear attached to the end of a wand that can be easily passed through the mouth. For a more thorough examination, the information acquired by the scanner can be magnified and shown on an LED monitor. This technique outperforms standard x-rays by allowing the dentist to record the intricacies of the jaw, gingiva, and teeth to an unprecedented degree.

Motion adjustment systems in intraoral scanners can take three-dimensional scans of the dentition, estimate a motion trajectory from one scan to the next, and then generate a corrected scan by balancing for the motion tracking. Assessing the motion route often includes one or more of the following:

  • Recording a scan to another scan and determining whether the mobility between the scans is within a registration limit.
  • Evaluating an optical flow based on local motion between subsequent two-dimensional images taken during the scan, estimating and improving a motion trajectory of a point in the scan using the optical flow.
  • And measuring a motion trajectory of a point in the scan using the optical flow. The data is usually generated in STL or DCM format by most scanners.
  •  

While accuracy is paramount, intraoral scanning technology is evolving in ways that make it more practical and acceptable for dental use.

  • CAD/CAM systems are becoming smaller and more practical in design, with some weighing less than half of a pound, making it easier for dentists to capture some of the most difficult portions of the mouth without requiring patients to open their mouths too wide. Intraoral imaging will probably become more interesting to more dentists as the scanners become closer in size to the hand equipment dentists use regularly. Scanners that are both flexible and wireless have also been developed.
  • Some scanners can capture a full arch in under a minute, and others can provide a CAD models file in seconds. The digital procedure becomes easier for both the dentist and the patient since faster scans become possible with time.
  • For a variety of purposes, impression scanning has become more popular. Even scanners that generate exclusive files have STL export modules, which can be imported into implant planning software and used with DICOM soft wares from CBCT scanners to design and construct implant guides.
  • The ability to trace the patient’s orthodontic records with high precision from the initial scan through the life of the case enables easy visualization of what changed, where it shifted, and how it shifted, for laboratories that build orthodontic appliances. The bubbles that are common on models are not a problem with the scan file.

Conclusion

Dental technology is continually evolving, and it will only be a matter of time before speed, precision, and size are adjusted to better fit the needs of the profession. The global market for digital impression scanners is expected to increase, indicating that this technology is expected to become more common in dental offices. Finally, these advancements are transforming dentistry; accepting them will enable dentists to deliver the finest treatment possible to the patients.
