• Resumen

    Prosthetic dentistry involves functional and esthetic restoration. Some situations require the use of fiber-reinforced composite resin posts that help preserve restorations. This paper demonstrates the usefulness of endodontic guides for the removal of fiber posts. A 36-year-old man consulted for retreatment of a maxillary first molar presenting a periapical pathology. This tooth revealed a composite reconstruction together with a glass-fiber post in the palatal root canal. To assist removal, use of an endodontic 3D-printed guide was indicated. A cone beam computed tomography examination and an optical impression were made to produce a tooth-supported guide by means of implant planning software (Blue Sky Plan, Blue Sky Bio®). The software enabled definition of a drilling pathway, which was transferred clinically using a resin template together with a sleeve and a 0.75-mm drill. The drill was guided as far as the gutta-percha situated in the apical third, limiting any risk of impairment or perforation.
