Indicação, técnicas e materiais dos pinos de fibra de vidro: revisão de literatura

Abstract

This study aimed to analyze each type of core, noting the advantages, disadvantages, indications and contraindications for its use in dentistry through a revision of the literature. Thus, this one can elucidate the professionals to the best and most suitable material to be used for each clinical situation. There are several situations where the dentist surgeon faces big losses coronary structure resulting from caries, fracture, a previous restoration, endodontic treatment. Planning for these cases should include the replacement of the lost crown clinic to ensure the successful achievement of the final restoration. Furthermore, it must be analyzed and the internal anatomy of the tooth, the remainder coronary occlusion and type of prosthetic reconstruction to be performed, such that the maximum structure is preserved, without compromising retention of the core and the resistance of the tooth. The use of pins and cores cemented inside root canals of endodontically treated teeth constitutes a valuable tool for dentists. The replacement structure with coronary lost dental materials through direct or indirect techniques may be required, and the anchoring of these materials in root canals and call intraradicular retention. The systems of prefabricated fiber glass have the following advantages: to provide refraction and transmission colors through the internal tooth structure, porcelain or resin, without the necessity of using opaque or modifiers and chemical adhesion to resins for dental use, require no treatment of its surface. By observing the aforementioned factors, one should be the criterion to indicate which material to be used, hence the relevance of a proper planning before initiating the treatment of the patients.
