COLAGEM DE FRAGMENTOS: UMA ALTERNATIVA DE REPARO PARA FRATURAS DENTÁRIAS - REVISÃO DE LITERATURA.

Introduction: coronary fractures of anterior teeth are frequently observed in both children and adolescents because the position of these elements in the oral cavity is quite vulnerable. Because of that, the collage of fragments appears as a viable alternative of repair of the dental elements once they have suffered some type of trauma. Objective: this study aims to present, through a bibliographic review, the fundamentals, advantages, disadvantages and applications of this surgical technique. Materials and Methods: we conducted a survey in the scientific literature, using review articles found in PubMED / Medline, Lilacs and Scielo databases. Articles were selected according to the inclusion criteria: availability of the full text of the study and clarity in the methodological detail used. The descriptors used were "tooth fragment" and "reattachment". Results: fragment collage can be applied to vital and non-vital teeth, depending on the size of the fracture, periodontal conditions, the biological width of the invasion, among other factors. It is a simpler procedure and has a higher durability than composite resin restorations. On the other hand, if the fragment is not well hydrated, color changes may occur, in addition to the possibility of fragment displacement. Conclusion: due to the advances and improvements of this technique, dental bonding fragments is an excellent clinical option for the functional and esthetic reestablishment of the compromised dental structure.
