Comparative Study of Continuous Polyethylene Fibers Reinforced with Composite Resins: An in Vitro Study

Abstract

Polyethylene continuous fiber is noted for its excellent mechanical properties, being used as reinforcement in dental restorations. When combined with composite resins, it offers high tensile strength, which allows it to withstand high forces without fracturing due to its flexibility. This material is also resistant to corrosion and chemicals, and comes in various forms, such as sheets, tubes or wires, which broadens its applications. The objective of the study was to evaluate which experimental group presents the best mechanical properties under compression. A mixed descriptive, cross-sectional and experimental methodology was used. The results showed that group 2, composed of R+S ribbond and silane, presented the highest values of compressive strength. The use of appropriate protocols, together with materials such as silane and everX in composite resins, significantly improves compressive strength
