INTERMEDIÁRIOS PARA PRÓTESES PARAFUSADAS: PILARES QUE UTILIZAM DOIS PARAFUSOS.

Introduction: implantology has established itself as a reality thanks to the longevity of the treatments and the functional results obtained. However, certain clinical situations made it difficult to apply due to the limitations of certain components, sometimes aesthetic, sometimes mechanical. Objective: to evaluate the indications, contraindications, advantages, disadvantages and applicability between the main types of intermediate screw bolts using two screws, in fixed and partial implants on implants. Methods: a systematized literature review was performed in the electronic databases, Bireme, Pubmed, Medline, and in the capes portal. Conclusion: the selection of prosthetic components is a prerequisite for the success of oral rehabilitation, and is closely related to the prosthetic modality to be used in oral implant restorations. Therefore, for an adequate selection, it is important to know not only the different options of components available in the market, but also to be familiar with the clinical picture of the patient, in order to obtain favorable results.
