Clinical Alternatives for the Use of Compactable and Flowable Bulk-Fill Composites: A Step-by-Step Case Report

Abstract

The use of Bulk-Fill composite resins to perform posterior restorations has been massified in recent years in the different clinical disciplines of Dentistry. This may be due mainly to the simplicity in the application technique of this material as it requires its insertion into the cavity preparation in 4-5mm of composite resin thickness, achieving a considerable reduction of clinical working time. Given the existence of different viscosities of this type of composite resins, certain difficulties have been identified before the selection of each Bulk-Fill material related to the possible combinations that can be made between the different brands available in the market, even when they are used with conventional composite resins. The purpose of the following case report, is to present two step-by-step clinical possibilities using initially, compactable Bulk-Fill composite resin in a single increment for the restoration of a second upper molar, and later, through the combination of Bulk-Fill flowable composite resin together with compactable Bulk-Fill composite resin and a high-refractive-index enamel-like conventional composite resin, for a first upper molar.

Estudio comparativo de los diferentes tipos de resinas compuestas y sus usos de acuerdo a su composición. Revisión de literatura

“…Cuentan con partículas de un tamaño entre 10 y 50 μm debido a esta característica poseen una resistencia a las fracturas junto con una mayor carga de relleno aumentando también su durabilidad sin embargo existen ciertas desventajas como la dificultad para pulirlas lo cual nos va a generar una superficie más rugosa y molesta para el paciente así como una mayor acumulación de placa, además posee una menor radiopacidad volviéndola radiolúcida [26]. Estas resinas tienen la presencia de quarzo y vidrio de estroncio en su componente inorgánico [27].…”

Influence of compressive forces and aging through thermocycling on the strength of mono incremental dental composite resins

“…A comparison between compactable and flowable bulk-fill composite resins revealed that compactable resins exhibit superior physical-mechanical properties, including conversion value, elastic modulus, flexural strength, and surface hardness 24 . The distinct advantages of these resins have propelled their widespread global use, allowing for increased thickness in restorations.…”

“…The distinct advantages of these resins have propelled their widespread global use, allowing for increased thickness in restorations. This capacity is attributed to the dynamic interaction between photoinitiators and the high transparency inherent in these materials 24 . Moreover, in vitro studies examining the compressive strength of conventional and bulk-fill resins have consistently underscored the enhanced strength of bulk-fill composite resin 25 .…”
