Introduction: Dental decays remain the most common and rampant biofilm-dependent oral disorders. Influencing the delicate dynamic between demineralization and remineralization is a big challenge in clinical practice, and nanotechnology is considered a viable solution. The therapeutic management of caries, which includes nanotechnology, has two big approaches, an antibacterial one and a remineralizing one. Silver is recognized to display a powerful toxicity to a large variety of micro-organisms, thus silver-based composites have been widely used in several bactericidal applications.

Digital imprint and computer-aided design/computer-aided manufacture (CAD/CAM) systems offer several benefits compared to traditional techniques. The use of a CAD/CAM system to scan preparations and generate restorations in-office, removes a second appointment for the patient. The existence of precision benefits in using complete systems and chairside scanning systems, has been proven. CAD/CAM restorations have a good longevity and meet the accepted clinical parameters. New digital impression methods are presently accessible, and before long, the long-awaited goal of sparing patients of one the most unpleasant practices in clinical dentistry, acquiring dental impressions, will be exchanged by intraoral digital scanning. CAD/CAM systems existing nowadays, can feed data through accurate digital scans created from plaster models, straight to manufacturing systems that can shape ceramic or resin restorations with no requirement of a physical copy of the prepared, adjacent, and antagonist teeth.

Three-dimensional (3D) printing is an additive manufacturing method in which a 3D item is formed by laying down successive layers of material. 3D printers are machines that produce representations of objects either planned with a CAD program or scanned with a 3D scanner. Printing is a method for replicating text and pictures, typically with ink on paper. We can print different dental pieces using different methods such as selective laser sintering (SLS), stereolithography, fused deposition modeling, and laminated object manufacturing. The materials are certified for printing individual impression trays, orthodontic models, gingiva mask, and different prosthetic objects. The material can reach a flexural strength of more than 80 MPa. 3D printing takes the effectiveness of digital projects to the production phase. Dental laboratories are able to produce crowns, bridges, stone models, and various orthodontic appliances by methods that combine oral scanning, 3D printing, and CAD/CAM design. Modern 3D printing has been used for the development of prototypes for several years, and it has begun to find its use in the world of manufacturing. Digital technology and 3D printing have significantly elevated the rate of success in dental implantology using custom surgical guides and improving the quality and accuracy of dental work.

This article from the Romanian Journal of Oral Rehabilitation explores the impact of sintering temperatures on the assessment of dental ceramics. The study reveals that deviations in sintering temperatures can lead to changes in the density, mechanical properties, and color of the ceramic. The article also discusses the use of IPS Dentcisal powders and a spectrophotometer for shade matching and ceramic layering in dental restorations. However, the study found that despite these tools, the registered shades did not always align with the expected shade or shade guide. The findings highlight the importance of precise control over sintering temperatures and a comprehensive understanding of their effects on dental ceramics. [Extracted from the article]

This article, published in the Romanian Journal of Oral Rehabilitation, compares the time efficiency of conventional and digital impression methods for prosthodontic restorations. The study found that digital impressions were faster than conventional methods, especially for fewer teeth. However, conventional impressions provided better fidelity in the cervical area. The study emphasizes the importance of choosing impression methods based on time efficiency and patient needs. Other studies mentioned in the article also provide insights into different techniques used in dentistry. [Extracted from the article]

This article, published in the Romanian Journal of Oral Rehabilitation, examines the benefits of using digital flow in the management of dental prostheses restorations. The study compares traditional impressions to intraoral and extraoral scanning, as well as plaster models to virtual and printed models, in terms of time and accuracy. The findings indicate that digital impressions require less time than traditional ones, but traditional impressions are still necessary for certain cases. The accuracy of the prosthodontic field reproduction also affects the fit of the restorations. The article also discusses the time required for different dental impression techniques, including traditional impressions and digital intraoral scanning. The study found that the duration of the impression procedure is influenced by the dentist's efficiency and the patient's cooperation. The time required for traditional impressions varied depending on factors such as the type of material, technique, and purpose of the impression. Impressions for pediatric or orthodontic cases using alginate materials were completed in a significantly shorter time. The article also explores the time investment for intraoral scanning and model casting. Overall, the study emphasizes the importance of material selection and technique application in dental procedures and highlights the variability in time requirements. [Extracted from the article]
