Abstract (English):	Contemporary Dentistry has been progressively integrating digital technologies, notably the CAD/ CAM (Computer-Aided Design/ Computer-Aided Manufacturing) system, which is replacing traditional analog methods in the fabrication of intraradicular posts. In this context, customized fiberglass posts have emerged as a promising alternative to prefabricated models, offering better root canal adaptation, thinner cement layers, enhanced adhesive strength, and reduced fracture risk. This literature review aimed to investigate the main fabrication techniques, available luting agents, and their influence on the retention and strength of restorations. The findings indicate that CAD/CAM posts outperform conventional ones, particularly regarding marginal adaptation and adhesion. In contrast, cast metal cores, although widely used in the past, present significant drawbacks such as lack of adhesion, corrosion potential, and high stress transmission to root structures. Despite the limited number of studies on CAD/CAM-customized posts, preliminary data suggest notable clinical advantages, including improved marginal fit, higher retention, and reduced chair time. However, restorative success remains dependent on the strict adherence to clinical protocols, from material selection to precise cementation within the root canal [ABSTRACT FROM AUTHOR]
Abstract (Portuguese):	A Odontologia contemporânea tem incorporado avanços tecnológicos significativos, sobretudo com a consolidação do sistema CAD/CAM (Computer-Aided Design/ Computer-Aided Manufacturing), que vem progressivamente substituindo métodos analógicos na confecção de retentores intrarradiculares. Nesse cenário, os pinos de fibra de vidro personalizados surgem como alternativa promissora aos modelos pré-fabricados, oferecendo melhor adaptação ao canal radicular, menor espessura de cimento, maior resistência adesiva e redução do risco de fraturas. O presente estudo, por meio de uma revisão da literatura, teve como objetivo investigar as técnicas de confecção desses retentores, os materiais de cimentação empregados e os impactos dessas variáveis na resistência e retenção da restauração. Observou-se que os pinos CAD/CAM apresentam desempenho superior aos convencionais, especialmente no que tange à adesividade e à adaptação marginal. Em contraposição, os núcleos metálicos fundidos, embora historicamente utilizados, demonstram limitações expressivas, como ausência de adesividade, risco de corrosão e transmissão excessiva de tensões à raiz dentária. Ainda que os estudos sobre pinos customizados por CAD/CAM sejam incipientes, as evidências apontam para benefícios clínicos relevantes, incluindo maior previsibilidade restauradora e diminuição do tempo clínico. Ressalta-se, contudo, que a longevidade do tratamento depende da aplicação rigorosa do protocolo clínico, contemplando desde a escolha adequada dos materiais até a cimentação criteriosa no conduto radicular [ABSTRACT FROM AUTHOR]
