3D Digital Impression Systems Compared with Traditional Techniques in Dentistry: A Recent Data Systematic Review

Abstract

The advent of new technologies in the field of medicine and dentistry is giving improvements that lead the clinicians to have materials and procedures able to improve patients’ quality of life. In dentistry, the last digital techniques offer a fully digital computerized workflow that does not include the standard multiple traditional phases. The purpose of this study is to evaluate all clinical trials and clinical randomized trials related to the digital or dental impression technique in prosthetic dentistry trying to give the readers global information about advantages and disadvantages of each procedure. Data collection was conducted in the main scientific search engines, including articles from the last 10 years, in order to obtain results that do not concern obsolete impression techniques. Elsevier, Pubmed and Embase have been screened as sources for performing the research. The results data demonstrated how the working time appears to be improved with digital workflow, but without a significant result (P = 0.72596). The papers have been selected following the Population Intervention Comparison Outcome (PICO) question, which is related to the progress on dental impression materials and technique. The comparison between dentists or practitioners with respect to classic impression procedures, and students open to new device and digital techniques seem to be the key factor on the final impression technique choice. Surely, digital techniques will end up supplanting the analogical ones altogether, improving the quality of oral rehabilitations, the economics of dental practice and also the perception by our patients.

Worldwide 3D Printers against the New Coronavirus

“…Three-dimensional printers and millers are now widely used in the world; both in the medical field and in other areas such as electronics, engineering, construction, and military fields [1]. Technological development has made it possible to print (or mill) different materials, with multiple characteristics, and with good resolutions and reliability compared to analogue techniques [2][3][4]. 3D (3 dimensional) printing (or additive manufacturing) allows the creation, starting from a digital model, of three-dimensional physical objects, by depositing, layer by layer, of overlying materials.…”

Bone Density Micro-CT Assessment during Embedding of the Innovative Multi-Spiked Connecting Scaffold in Periarticular Bone to Elaborate a Validated Numerical Model for Designing Biomimetic Fixation of Resurfacing Endoprostheses

“…Similar to the study by Cicciù et al [ 43 , 44 ], micro-CT imaging data were used to adjust and justify the 3D geometrical model and the properties of the FE model for computational simulation. FE analysis has been widely applied for simulating mechanical stress distribution in an implant and the surrounding bone [ 45 , 46 , 47 , 48 ].…”

The Effect of Perioral Scan and Artificial Skin Markers on the Accuracy of Virtual Dentofacial Integration: Stereophotogrammetry Versus Smartphone Three-Dimensional Face-Scanning

“…However, for large featureless surface, difficulties arise in the stitching process because of the lack of reference image landmarks. The scanning accuracy of the intraoral scanners is considerably influenced by the distinguishability of the objects and the size of the scanning area [ 36 , 37 , 38 ]. It could be problematic for the intraoral scanners to correctly digitize the lip, philtrum, and nose because the structures do not have small and characteristic anatomic features in shape.…”
