To evaluate the three-dimensional adaptation of prefabricated Bio-Root inlays fabricated from impressions of simulated immature permanent root canals using four techniques: direct intraoral scanning (A), a light-body rubber impression digitized with an intraoral scanner (B), cone-beam computed tomography (CBCT)-based design (C), and a conventional indirect technique (D). Methodology.

Abstract This randomized controlled clinical trial evaluated the effectiveness of guided endodontic microsurgery (GEMS) compared to conventional endodontic microsurgery (EMS) in critical anatomy regions. Twenty-eight patients (ages 19–58 years) requiring endodontic microsurgery in critical anatomical regions were randomly allocated to guided surgery (n = 14) using 3D-printed surgical guides with trephine burs or conventional microsurgery (n = 14). Primary outcomes included surgical procedure time.

You are already at the latest version Background. Pulp necrosis in immature permanent teeth arrests root development, leaving an open apex, thin, divergent dentinal walls, and an unfavorable crown-to-root ratio that predisposes the tooth to fracture and complicate endodontic management. Apical barrier with hydraulic calcium silicate cements has become the first-line orthograde approach for these teeth when regenerative procedures are not indicated or feasible. Aim.
