Introduction Effective provisional restorations often lead to higher-quality final restorations, making the next appointment more convenient and time-efficient. Temporary restorations are necessary as they guarantee aesthetics, comfort and vitality of the teeth, oral function, maintenance of gum health and contour, as well as occlusion and positional stability. Temporary restorations also play an important role in diagnostic procedures, for example, in evaluating the impact of aesthetic and occlusal changes [1]. In many cases involving complex prosthetic rehabilitations, long-term temporary restorations with survival periods of approximately 6-9 months are required. Such measures are taken to help the patient adapt and adapt to, for example, changes in the occlusal vertical dimension (OVD) and functional alterations. Therefore, there is a need for a dental restorative material that is appropriate for the production of laboratory-made temporary restorations with adequate service life. Dental composites are resin-based restorative materials, that is, three-dimensional combinations of at least 2 constituent chemically disparate materials with a distinct interface. They are the most commonly used dental material for making temporary restorations. Contemporary dental composites possess good workability properties, color stability and are durable. However, composite restorations do not survive long in the mouth as their longevity is mainly hindered by fracture [2]. This is a significant issue since a major concern in prosthetic dentistry is the survival rate of temporary restorations for the expected duration of clinical service [3].
