FRCs (Fiber-Reinforced Composites) are materials that are being used increasingly more often in dentistry as an alternative to traditional restorations made of ceramics or metals. The aim of this study was to carry out a comparative analysis of the strength parameters of a light-curable dental composite reinforced with one single band and two single bands of artificial fibers. The specimens for the strength tests were prepared in accordance with the guidelines of the PN-EN ISO 4049:2019-07 international standard. The test material covered specimens of composite reinforced with single (one or two) bands of fibers. The following bands of fibers were used: carbon (WGL), aramid (AMD) and hybrid carbon–aramid (WGL-AMD). The presence of one single band of aramid fibers caused a three-fold increase in deflection, with a simultaneous increase in the Young’s modulus of over 140%. The flexural strength of specimens reinforced with one single band of aramid fibers was higher by 280% than that control group specimens (KONT). To summarize the performed tests, the incorporation of carbon, aramid and hybrid carbon–aramid fibers into organic matrix has a significant impact on the values of the mechanical parameters of dental composites. The results indicate that particular attention should be paid to aramid fibers, which have rarely been used in dentistry so far.

Introduction: It is estimated that masticatory system disorders occur in even 40-90% of the society, which classifies them as the most common dental problems. Postural disorders occurring in professional musicians, caused by frequently repeated non-physiological movements and the need to...

Acrylic resin remains the primary material used in the fabrication of removable prostheses, despite the continuous development of prosthetic materials science. The nature of the material’s composition requires frequent hygienic procedures and occasional disinfection, typically employing...

Background: Playing on the wind instruments can cause injuries in the stomatognathic system. For this reason, dentists are observing an increasing number of patients experiencing facial cranial problems arising from playing wind instrument. Regular dental visits alows to prevent these health...
