RESISTANCE TO FRACTURE OF ENDODONTICALLY TREATED TEETH, RECONSTRUCTED WITH PREFABRICATED FIBERGLASS PINS

Abstract

Uncovering teeth for endodontic treatment due to loss of coronary structure, mentioned above for reconstruction, using for this purpose intraradicular retainers, being possible from these to recover the lost shape and function. These retainers emerged with the purpose of promoting coronary support when more than half of the remaining tooth is lost, with the aim of improving the retention of the final restoration. Fiberglass Pins were introduced in dentistry in order to replace metallic pins, favoring a more pleasing aesthetic due to their color, better mechanical properties, being similar to the dental structure, unlike the cast core, which has a higher elasticity module. dental structure. In addition, this material offers less wear of intraradicular dentin, also dispensing with a laboratory step. The present work aims to compare the fracture resistance of endodontically treated and reconstructed teeth with intraradicular retainers. This literature review reviews the benefits and practicality of being sensitive to a fiberglass post, taking into account its main features. Fiberglass posts are an ideal choice for the dental element that has lost most of its structure, as they reinforce restorations and support prosthetic crowns on teeth endodontically. In addition to aesthetics, this material also has mechanical properties similar to dental structures, without causing stress and also prevents root fractures due to its modulus of elasticity being similar to dentin.
