Fracture Resistance of Prosthetic Restored Teeth with Fiberglass Posts versus Metallic Posts

Abstract:

Because of the great amount of hard dental tissues loss, most of non-vital teeth must be prosthetically restored using a post. The anchorage of these posts is based on enlarging the root canal, so the question is what type of endodontic post is more appropriate to use in order to ensure a favorable prognosis of these teeth, avoiding as long as possible their extraction. Loss of teeth is affecting not only the oral cavity and the dento-maxillary system, but also the quality of life of the patients, with both psychological and general health consequences. Even treated, the edentulous state determines major changes in diet and can be a cause of gastrointestinal disorders. This in vitro experiment tested the resistance to fracture of non vital teeth restored with different types of posts, in order to find out which type is best to use for their restoration. From the of this in vitro experiment it has been observed that in the case of teeth restored with metal posts, regardless of the diameter of the post, the failure of the sample was represented by root fracture. In the case of the teeth restored with fiberglass posts, the failure was caused by the fracture of the post or the fracture of the coronary part of the tooth.
