Abstract

ABSTRACT Bulk Fill Composite resins are restorative materials that present low tension and polymerization shrinkage, allowing them to be inserted in a single increment of up to 4 mm of thickness, in a restorative cavity. This paper aims to report a clinical case of restorations done on posterior teeth with Bulk Fill restorative system, using selective acid-etching with self-etch adhesive system. Patient, male, 24 years old, presented a carious lesion on the occlusal surface of dental element 37 and an occlusal unsatisfactory amalgam restoration, on element 36. A restorative treatment with Universal Bond 3M / ESPE and bulk fill composite resin (3M / ESPE) was done. According to the case described, it was possible to observe that the materials and techniques used restored the form and function of the teeth involved, preserving pulp vitality with a satisfactory aesthetic result. The bulk fill resins employed offer practicality and decrease clinical time, with satisfactory clinical applicability in the aesthetic and functional rehabilitation of posterior teeth.

Highlights

Composite resin can be considered as the most studied restorative material in the last decade
As a way of avoiding the clinical consequences of polymerization shrinkage, incremental filling techniques normally are preferred over the single increment method
The incremental technique can be important for adequate light penetration, some limitations are reported, such as the possibility of creating gaps or adhesive failures between layers, and increase of clinical time due to the necessity of light curing each increment [5]

Summary

Introduction

Composite resin can be considered as the most studied restorative material in the last decade. With the purpose of improving its mechanical and aesthetic properties, the quantity of filler particles, and its format, composition and organic matrix distribution, suffered alterations optimizing aesthetic, biological and functional results [1]. Some disadvantages, such as polymerization shrinkage, can still be observed and contribute to the decrease in longevity of the restorations, leading post-operative sensitivity and compromising marginal integrity [2,3] Polymerization shrinkage is a result of the movement and approach of the monomers amongst each other during the formation of the polymer chain. The incremental technique can be important for adequate light penetration, some limitations are reported, such as the possibility of creating gaps or adhesive failures between layers, and increase of clinical time due to the necessity of light curing each increment [5]
