“…However, utilizing the following proposed technique, one can quickly and predictably make repairs not only to defective margins but also to contours and insufficient interproximal contacts as well. Additionally, this protocol can be used to make corrections to acrylic materials, as it has been shown that composite resin can be used with success in the repair of freshly prepared provisional restorations fabricated from PMMA 19 . The use of flowable resins offers several advantages that include availability in numerous shades and viscosities, ease of use, increased working time, ability to polymerize on demand, low cost, minimal material waste, and accuracy 16 .…”

The importance of provisional restorations is often downplayed, as they are thought of by some as only "temporaries." As a result, a less-than-ideal provisional is sometimes fabricated, in part because of the additional chair time required to make provisional modifications when using traditional techniques. Additionally, in many dental practices, these provisional restorations are often fabricated by auxillary personnel who may not be as well trained in the fabrication process. Because provisionals play an important role in achieving the desired final functional and esthetic result, a high-quality provisional restoration is essential to fabricating a successful definitive restoration. This article describes a method for efficiently and predictably repairing both methacrylate and bis-acryl provisional restorations using flowable composite resin. By use of this relatively simple technique, provisional restorations can now be modified or repaired in a timely and productive manner to yield an exceptional result.CLINICAL SIGNIFICANCE Successful execution of esthetic and restorative dentistry requires attention to detail in every aspect of the case. Fabrication of high-quality provisional restorations can, at times, be challenging and time consuming. The techniques for optimizing resin provisional restorations as described in this paper are pragmatic and will enhance the delivery of dental treatment.(J Esthet Restor

“…Fox 12 used composites as an interproximal contact and marginal repair material for acrylic resin provisional restorations. Solow 13 incorporated a composite veneer into an acrylic resin provisional restoration to combine the esthetics of a microfill composite with the contour and marginal adaptation of an acrylic resin. Moreover, Dumbrigue 14 described a method for fabricating multiple-unit provisional restorations using a light-cured composite for the shell, a self-cured bis-acryl composite as the relining material and a flowable light-cured composite for improving marginal adaptation.…”

SUMMARYThis study evaluated the repair bond strengths of light-cured resins to provisional restoration materials with different chemical compositions and polymerization techniques. Fifty discs (10 mm in diameter and 1.5 mm thick) were fabricated for each provisional resin base material, including a self-cured methacrylate (Alike), selfcured bis-acrylate (Protemp 3 Garant), lightcured bis-acrylate (Revotek LC) and a heat-cured methacrylate (Namilon). All specimens were stored in distilled water at 37°C for seven days before undergoing repair with one of four lightcured resins, including AddOn, Revotek LC, Dyractflow and Unifast LC and a self-cured resin (Alike), according to the manufacturers' instructions, for a total of 200 specimens. After 24 hours of storage in 37°C water, the shear bond strengths were measured with a universal testing machine and fracture surfaces were examined under a stereomicroscope. Two-way ANOVA revealed that provisional resin-base material (p<0.001), repair material (p<0.001) and their interactions (p<0.001) significantly affected the repair strength. Tukey's multiple comparisons showed that the lowest bonding strengths were found in specimens of heat-cured methacrylate resin materials repaired with bis-acryl resins, with their failure modes primarily being of the adhe- Clinical RelevanceSpecific repair resins should be chosen for certain provisional materials, since optimal bond strength can be achieved only when the repair resin has similar chemical components to those of the resin matrix (either methacrylate or bis-acryl) for the provisional restoration.sive type. The highest bond strengths were recorded when the provisional resin-base materials and repairing resins had similar chemical components and the failure modes tended to be of the cohesive type.
