Digitalización aplicada en prótesis dental: revisión sistemática de la literatura”

CAD / CAM systems is the acronym of computer aided design / computer aided manufacturing, whose translation into Spanish means computer-aided design / computer-aided manufacturing, was introduced in dentistry with the aim of automating production and standardizing the quality of dental restorations; Intraoral scanners began to be used in the field of prosthodontics in the early 1980s through the concept of intraoral digital impressions. This got the integral attention of the dentists and has been used for the manufacture of dental prostheses in several cases. It is expected that the use of these scanners in the digital printing technique will generate an absolute digitalization in prosthodontics. Furthermore, some published articles have indicated that dental prostheses made from intraoral digital impressions have shown remarkable advantages over conventional impressions in several aspects. Methodology: This systematic review used the PRISMA (Preferred Reporting Items of Systematic reviews and Meta-analysis) guide to ensure the quality of the information included. To do this, the checklist of items included in said guide was handled. The PICO system was also used. Conclusions: the optical impressions reduce the patient's discomfort; they are efficient over time and simplify clinical procedures, allow better communication with the dental technician and with patients; however, with IOS, it can be difficult to detect deep margin lines on prepared teeth or in case of gingival bleeding.
