With the popularisation of upcoming digital technologies and the exposure of defects in traditional technology, computer-aided design and computer-aided manufacturing (CAD/CAM) have become widely used in the field of dentistry. An oral digital scanning system determines the ultimate accuracy of the prosthesis, which is an essential part of CAD/CAM. Numerous factors influence data collection for tooth scanning. Recent research shows that different scanning strategies can affect the accuracy of results. It has also been reported that different systems of intraoral scanners exhibit different experimental outcomes.

Nevertheless, there is a numerical difference in the influencing factors on account of the difference in scanning methods between oral scanners and intraoral scanners. Furthermore, these techniques can be used in tandem with additional complex scanning tools, including CBCT and MRI scans, aiding dentists with accurate treatment planning, improved communication with laboratories, and reduced treatment time. On the other hand, a wide range of materials are used in dentistry and a detailed microscopic examination is mandatory to evaluate their effect on biological systems. Techniques like scanning electron microscopy can play a key role for in depth study of clinical aspects of dentistry.

In this Special Issue, we aim to discuss the latest findings analysing scanning technology and their applications in dental science. We also want to discuss scanning analysis methodology and related issues in the fields of biology, physics, chemistry, material science, and advanced technologies. This Special Issue serves as a platform for researchers to publish their latest research and clinical findings, reviews and mini-reviews, and analyse evaluations to solve problems in medical applications.

Potential topics include but are not limited to the following:

• Intraoral and extraoral scanning of patients
• 3D modelling, imaging, and analysis of materials, cells, microorganisms, and chemical structure
• Advancements in 3D printing methods and technologies
• Precision and accuracy evaluation of virtual and physical models
• CAD/CAM research
• Micro/nano-scale characterisation of the materials
• Finite element analysis
