Additive manufacturing of provisional dental restorations proves to be an alternative to create restorations with accuracy and precision. With a low cost and manufacturing time, compared to CAD CAM technology.

Aim: Conduct a literature review to review the main characteristics that influence color stability in 3D printed provisional restorations, analyzing information on additive manufacturing, types of printers, or any other factor that influences the manufacturing of 3D printed restorations. 3D.

Methodology: An electronic search was conducted through PubMed, SCOPUS and Google Scholar using the keywords: “3D provisionals” OR “digital dentistry”, “3D printing” OR “additive manufacturing” OR “PMMA”.Only full text articles in English have been considered. Complete articles in English were considered. We identified 103 results and used 39.

Results: Among the main factors that affect color stability, agents such as coffee and red wine were identified, which can affect the original appearance of the restorations.

Discussion: The research highlights the importance of surface treatment and the degree of curing of materials to ensure long-lasting aesthetic results. Manufacturing orientation parameters on color stability have a lot of impact.

Conclusion: It is important to highlight that there are few scientific articles related to the effects of manufacturing orientation parameters on color stability.
