Comparison of Internal Adaptation of Bulk-fill and Increment-fill Resin Composite Materials

Abstract: The incrementally placed material FSU had the highest internal adaptation to the cavity surface, while the four bulk-fill materials showed varied results. Thermocycling influenced the existing gap area magnitudes. The findings suggest that the incremental-fill technique produces better internal adaptation than the bulk-fill technique.

“…The impact of at home and in-office bleaching agents on the color stability of bulk-fill composite resins INTRoDuCTIoN C omposite resins have been favored as restorative material over the years because they have advantageous properties for use in clinical practice, such as the coefficient of thermal-linear expansion, which is highly compatible with dental structure, higher compressive strength values, acceptable modulus of elasticity and hardness, as well as an excellent aesthetic result. [1] For the use of composite resins, the insertion was carried out in increments of 2mm at most, respecting cavity configuration factors, following the so-called incremental technique [2]. The main reasons for using this technique are to allow light penetration of the photopolymerizer throughout the depth of the layers, as well as to decrease polymerization contraction and associated stress [3].…”

“…The main reasons for using this technique are to allow light penetration of the photopolymerizer throughout the depth of the layers, as well as to decrease polymerization contraction and associated stress [3]. In this way, the possibilities of any failure in marginal sealing, cusp deflection, microleakage and consequent appearance of secondary caries are reduced [2].…”

“…[6][7][8][9] Entretanto a inserção de vários incrementos na restauração de cavidades extensas e profundas em dentes posteriores, além de consumir mais tempo clínico, aumenta a probabilidade de contaminação durante o procedimento, [10][11] de incorporação de bolhas no interior da RC 12 e de detritos entre as camadas de RC. 13 Assim, para simplificar a técnica restauradora e diminuir o tempo clínico, surgiram as RC do tipo bulk fill (BF) ou de preenchimento único. [14][15][16] Maior profundidade de polimerização, menor contração e menor tensão na interface dente-restauração 17,18 sustentam a inserção das RCBF em incremento único de 4 a 5 mm de espessura para a restauração de dentes posteriores.…”

“…The polymerization shrinkage is an inherent characteristic of the resin composites (Braga et al, 2005;Rizzante et al, 2019), which depends on a number of factors including the material composition, the degree of conversion, the volume, and the elastic modulus (Braga et al, 2005;Braga et al, 2012;Benetti et al, 2014;Kim and Park, 2014;Van Dijken and Lindberg, 2015;Ferracane and Hilton, 2016;Han et al, 2019). The fact is that stress cannot be considered an isolated factor when it comes to the marginal adaptation of resin composite restorations; other factors, such as thermal changes and occlusal loads (Kim and Park, 2014;Van Dijken and Lindberg, 2015), placement of resin composite (Furness et al, 2014;Yoshimine et al, 2015;Correia et al, 2018;Alqudaihi et al, 2019), curing technique (dos Santos et al, 2007;Gamarra et al, 2018), cavity size and geometry (Braga et al, 2006;Borges et al, 2014;Han et al, 2016;Han et al, 2019) also may have a significant effect.…”

“…There are several reports on marginal gap formation and factors affecting its development (Versluis et al, 1996;Peutzfeldt and Asmussen, 2004;Braga et al, 2006;dos Santos et al, 2007;Furness et al, 2014;Benetti et al, 2015;Alqudaihi et al, 2019;Han et al, 2019). Different techniques and introducing of new polymeric systems have not been effective in eliminating the shrinkage stress and, thus, in reducing the gap formation (Versluis et al, 1996;Yoshimine et al, 2015;Correia et al, 2018;Gamarra et al, 2018;Han et al, 2019;Alqudaihi et al, 2019;He et al, 2019). However, studies suggest that marginal bevels can reduce or eliminate the microleakage and gaps associated with resin composite restorations (Opdam et al, 1998;Coelho-de-Souza et al, 2008;Coelho-de-Souza et al, 2010;Borges et al, 2014).…”
