Avaliação do desempenho clínico de restaurações clase II com resina bulk-fill: uma comparação entre o uso de unimatrix r e cunha elástica

Abstract

Composite resins have reached an increasing space in restorative dentistry, as they are able to precisely resemble the optical characteristics of the tooth, offering optimal esthetics. New technologies allied to new materials appear in order to facilitate the daily clinic, reducing the number of steps, and taking less clinical time to obtain good results, being an example the Bulk Fill resin - the material that allows the manufacture of single increments of up to 4mm. Current dentistry allows the fabrication of perfect restorations from an esthetic point of view, however, as for the proximal area, greater attention must be given to obtaining the interproximal contact point. Achieving a perfect interproximal relationship is important forthe maintenance, function and balance of teeth in the arch, protection of the periodontium andothers, which is directly related to the type of matrix used. Thereby, the matrix systems, such as the elastic wedge and unimatrix R, emerged to help create an ideal contact point.The aim of this clinical case it is report compared the Bulk-fill resin and matrix systems [sectioned metallic matrix (unimatrix) and elastic wedge] will be used, comparing through clinical evaluation and radiographs which of the materials presented better results with reference to the quality of the interproximal contact point made. Bulk fill resin restorations were placed in the patient using different matrix systems. After a 6-month clinical evaluation, it was possible to observe that, regardless of the matrix used, all restorations presented a good clinical performance, especially with regard to the quality of the contact point.
