Dental impression making is the process of creating a negative form of the teeth and oral tissues, into which gypsum or other die materials can be processed to create working analogues. Contemporary dentistry generates new information every year and digital dentistry is becoming established and influential. Although dentists should stay abreast of new technologies, some of the conventional materials and time-tested techniques remain widely used. It is important to review the impression-making process to ensure that practitioners have up-to-date information about how to safely and effectively capture the exact form of the oral tissues to provide optimal patient management...

Digital dentistry has influenced many dental procedures, such as three-dimensional (3D) diagnosis and treatment planning, surgical splints, and prosthetic treatments. Patient-specific protective appliances (PSPAs) prevent dental injury during endotracheal intubation. However, the required laboratory work takes time, and there is the possibility of tooth extraction while obtaining the dental impression. In this technical report, we utilized new digital technology for creating PSPAs, using direct intraoral scanners and 3D printers for dental cast fabrication...

The increasing use of dental implants rather than fixed cantilever bridges for standard dental restorations has led to the development of multiple materials in this field. The goal in modern dentistry in recent years has been to achieve results in implantology that match the natural dentition in esthetics and function. Constant efforts have been made to achieve a perfect emergence profile, and to individualize the surrounding periimplant soft tissue. Powder-free digital scanning is now possible, which allows for the computer-assisted design/computer-assisted manufacturing (CAD/CAM) of ready-to-fit customized immediate implant abutments in various appropriate materials...

The final outcome of dental treatment needs to be not only clinically sufficient, but also esthetically pleasing. Bilateral symmetry in the maxillary incisor teeth is of significant importance in esthetic dentistry. In restorative dentistry, symmetry refers to the appearance of balance around the dental midline. The purpose of this study was to measure and compare the maxillary incisor teeth dimensions from both sides of the dental midline, in order to asses if this symmetry occurs naturally. From the student community population at Tel Aviv University, 66 students between the ages of 20-35 (35 males, 31 females) were enrolled and gave consent...

REVIEW
Markus Zaruba, Albert Mehl
Since Cerec (Chairside Economical Restoration of Esthetic Ceramics) was introduced as the first dental chairside computer-aided design/computer-aided manufacturing (CAD/CAM) system in the mid-1980s, this technology has enjoyed growing popularity, particularly in the recent past. There has been a considerable increase in the number of available chairside systems in only the last few years. One of the main reasons for this is that intraoral scanners have become increasingly better, smaller, and faster, while the design software has become more and more user-friendly...
