Will CAD/CAM Technology Increase the Effectiveness of Clinicians?

Abstract

OBJECTIVES

CAD/CAM stands for computer-aided design/computer-aided manufacturing. It is a digital system that employs CAM to translate designs from CAD into tangible goods. CAD/CAM intraoral scanners aim to make practitioners more effective in dentistry.

METHODS

The criteria selection is based on a study conducted with research articles. These articles were included and/or excluded based on the following criteria: articles should be peer reviewed, not published before 2018 and not literature reviews or meta-analysis. The database used to conduct this literature review was PubMed through Augusta University's online library database. The keywords used to find relevant articles were CAD/CAM, computer-aided design, computer-aided manufacturing, computer-assisted manufacturing, accuracy, intraoral scanner, high resolution, anxiety, stress, fear, nervousness, dental phobia, time distribution, time administration, effective planning, and time management.

RESULTS

To demonstrate that CAD/CAM improves clinician accuracy and efficacy, three separate studies were carried out. In the first study, an intraoral scanner is used to examine the accuracy of digital impressions at the edge of crown preparation using different scanning methodologies. A mandibular first molar was created entirely of ceramic on a typodont. Three settings—high solution, ordinary resolution, and combination resolution—were used to get the desired impression. Study two was carried out. Five skilled doctors and five less skilled clinicians were randomly allocated to build interim single crowns using digital sextant imaging. Research 3 found that using CAD/CAM would improve implant placement when comparing free-hand surgery to using the s-CAIS surgical guide for insertion.

CONCLUSIONS

Any intraoral scanner's accuracy is entirely dependent on the machine's hardware and is tuned for default scans. Compared to a traditional workflow, a single crown made with CAD/CAM needed less fabrication time and produced a better fit. competent to materialize dental implants, removable prosthodontics, veneers, crowns, inlays, onlays, and full mouth rehabilitation.

IMPLICATIONS

This stage of the scanning process is undesired because it requires more time to digitally trim away the preparation margin and set up a High-resolution mode in the program. Additionally, the increasing volume of computer data required to create scans makes this step necessary. Research II In a traditional workflow, less experienced Clinicians took longer to make temporary crowns. Study 3: To avoid errors resulting from provider omission, clinicians need to be trained in the proper use of CAD/CAM.
