Influência do tipo de retentor intracanal direto naresistência de dentes unirradiculares com canais amplos: uma revisão sistemática

Abstract

The use of posts is a viable alternative for the restoration of endotically treated teeth with structural structural loss, in order to increase and increase the radicular. Different types of treatment are considered in order to maintain an aesthetic and functional standard. The aim of the study was to perform a systematic review to determine an influence of the type of direct intraradicular retention on the strength of single-rooted teeth with endodontically treated permanent wide canals. The present study follows the PRISMA criteria for reporting reviews and meta- analyses. Our research question was formulated using the P.I.C.O. The study selection process was carried out by two reviewers independently, using the same previously trained eligibility criteria. The selection was carried out in four stages: by title, abstracts, full study and quality analysis. Data were organized and analyzed in Stata11.0 software. Among treatments for single-rooted teeth with wide or weakened canals, such as restorations with fiberglass posts in conjunction with composites, with fiber accessory posts and anatomical posts demonstrated greater resin strength and bond strength than those treatments without seams, that use posts with resin cements, fluid resins or resin reinforcing tapes, not unlike the original cast metallic controls. In most cases, the most common fractures were repairable or non-catastrophic. Metal groups Cast posts have the highest strength results and the groups with the broadest instrument controls and the best bond strengths and with the highest strength results to large teeth. The use of refurbished or fiber-reinforced glass treatment posts refurbished or supplemented with accessories such as a root-joined restorative with treated wide canals and post-bonded and favorable fracture resistance pattern.
