Unlocking the Future of Dentistry with Intraoral Scanners

Abstract

Dental medicine is advancing at an exceptionally fast rate, one of its main reasons being the integration of digital technologies.  Intra-oral scanners have now recently gained a lot of importance in the dental field. The existing intraoral scanners use different scanning strategies in order to obtain higher accuracy. Here our aim is to gain knowledge and evaluate the effectiveness of different scanning strategies of intraoral scanners. Different scanning strategies of intraoral scanners are evaluated which include 1) Accordion fringe interferometry 2) Confocal laser scanning microscopy 3) Active wave front sampling 4) Optical coherence Tomography. Also, there are other conventional techniques such as active and passive sterotriangulation. On evaluating the different methodologies, intraoral scanners using confocal laser scanning have the upper hand compared to others due to their elimination of out-of-focus points, and blur-free, high-resolution images. Present Intraoral scanners using these strategies are Trisos (3 shapes), 3D progress and CS3500.
