“…It was concluded that changes in FS may be multifactorial. The change in FS can be influenced by parameters of the resin composite for provisional restorations, such as the types of filler along with its content, the composition of the monomer in the resin matrix, and even the addition of plasticizer [27].…”

Direct restorations are currently the most popular restorations used in dental prosthodontics. Due to the increased requirements for materials used in the fabrication of fixed restorations, there is a need for evaluation of strength parameters of these materials, including dental cements. The present study investigated the change in selected strength parameters of four dual-cured composite cements as a function of storage temperature. The following were investigated: three-point flexural strength (FS), flexural modulus in bending (FM), diametral tensile strength (DTS) and Vickers hardness (HV). Four dual-cured composite cements were tested, i.e., Multilink Automix (Ivoclar Vivadent), seT PP (SDI), MaxCem (Kerr), and Bifix Hybrid Abutment (VOCO). Each of the tested cements was stored for 7 days at one of the selected temperatures: 8 °C, 15 °C, 25 °C, or 35 °C, before the samples were made. Strength properties (DTS, FS) are not strongly dependent on the storage temperature in the range of 8–35 °C. Some statistical differences were observed between the hardness of MaxCem and Multilink Automix storage in various temperatures. FS and FM were lowest for Bifix Hybrid Abutment, MaxCem and Multilink Automix storage at 25 °C, and highest for Bifix Hybrid Abutment, MaxCem, and seT PP stored in 35 °C. The cement with the highest filler content (70% by weight) showed the highest FS and HV.

“…Their filler amount resembles that of flowable composites rather than conventional restorative composites, which are more viscous to facilitate sculpting [8]. The filler content of provisional composite materials is lower [9]. The main difference between conventional restorative composites and provisional composite materials is their polymerization systems.…”

Although extraoral fabrication of temporary restorations has many benefits and is easy owing to CAD/CAM evolution, dentists often make provisional crowns and bridges intraorally [1,2]. Various provisional materials are available for direct fabrication. Although unfilled poly(methyl)methacrylate (PMMA) resins have been conventionally used, there has been a clear trend toward the use of composite materials for temporary purposes in the past five years [3]. As composites for provisional use represent a specific category of dental composites, with specific indications, handling properties, mechanical and esthetic characteristics, this group of materials will be referred to in this research article as "provisional composite materials" [4,5].Provisional composite materials were first introduced to the market over 30 years ago; however, they were expensive because they required an automated dual-paste delivery system [4]. Their current popularity can be attributed to their ease of use, reduced cost, superior esthetic properties, and extended indications [6]. In addition to the fabrication of provisional crowns, these composites are often used for diagnostic mock-ups, as a tool for communication with patients and dental laboratories [7].In the past, this group of composites has also been called J Prosthodont Res. 2024; **(**):
