Abstract
In the actual times, with so many rehabilitation techniques and endodontic posts in the market, there are many doubts about which one is the best, the most cost-effective, the one that has more resistance among other questions. This work aimed to compare the intraradicular restorative treatments that involve the use of prefabricated posts and posts made with CAD-CAM, through a literature review in order to reinforce these procedures. Articles and other literary sources with interrelation to CAD-CAM and endodontic posts were surveyed through search in Pubmed, Scielo, Scopus, Lilacs and Google Scholar databases. The keywords: endodontic posts, CAD-CAM, prefabricated posts, customizable posts, fiberglass, carbon fiber were used. More than 100 articles were found, and after reading the abstract, 50 were selected. After reading, 26 were selected for the review. After reading, analyzing and interpreting the scientific studies, it was possible to verify that the CAD-CAM endodontic posts have satisfactory results, although there are few specific studies on them compared with the metallic cast posts and prefabricated posts.
Highlights
For many years, the gold standard for endodontically treated teeth with extensive loss of dental structure has been the manufacture of metal-ceramic crowns or total crowns in pure ceramics, with or without endodontic post

Intracanal pins are cylindrical or conical structures, traditionally made of metal fiber or fiber used in the root canal of endodontically treated teeth
Summary
The gold standard for endodontically treated teeth with extensive loss of dental structure has been the manufacture of metal-ceramic crowns or total crowns in pure ceramics, with or without endodontic post. Intraradicular dental posts are used in dentistry to create retention for the restoration (Allan & Foreman, 1989). Some materials are used in the manufacture of intraradicular retainers, including chromium-cobalt and nickel-chromium for cast metal posts, titanium for the prefabricated metallic posts and carbon fiber and glass fibers (Allan & Foreman, 1989). The prefabricated posts have the disadvantage of presenting a large cementation line compared to the cast metal posts (Spazzin et al, 2009; Verissimo et al, 2014). The anatomical post technique presents the advantages of the prefabricated fiberglass post without the disadvantage of the cementation line (Grandini et al, 2003)
