Chairside fabrication of provisional crowns on FDM 3D-printed PVA model
Journal of Prosthodontic Research, 2020The purpose of this study was to evaluate the dimensional accuracy of crowns fabricated using a polyvinyl alcohol (PVA) dental model.An intraoral scanner (LAVA TDS) was used to scan a prepared molar abutment as a master model. The STL file obtained from the scanning process was transferred into the FDM 3D printer (Value 3D Magix MF-1000) and then ...

PULPAL RESPONSE AFTER COMPLETE CROWN PREPARATION, DENTINAL SEALING, AND PROVISIONAL RESTORATION
Journal of Esthetic and Restorative Dentistry, 1995This study evaluated the acute pulpal healing response following preparation, etching, and sealing of the prepared vital dentin with a 4-methacryloxyethyl trimellitate anhydride (4-META) bonding system. Adult monkey teeth received crown preparations with chamfer margins, prepared with a diamond used at ultra high speed with water cooling.

Composite veneered acrylic resin provisional restorations for complete veneer crowns
The Journal of Prosthetic Dentistry, 1999Restorations that are remade to improve esthetics, teeth with pronounced gingival-to-incisal color contrast, or high-value translucent teeth can limit the capability of shaded acrylic resin provisional restorations to satisfy the esthetic demands of certain patients.

Temperature rise in the pulp chamber during fabrication of provisional crowns
The Journal of Prosthetic Dentistry, 1989This study measured and compared thermal changes in the pulp chamber during the fabrication of provisional crowns by direct method using various brands of autopolymerizing resin systems. The effect of curing the crowns in condensation and addition-reaction silicone putty matrices was also evaluated.

Temperature rise in pulpal chamber during fabrication of provisional resinous crowns
The Journal of Prosthetic Dentistry, 1997The heat generated during the exothermic polymerization reaction of autopolymerizing resinous materials and the heat generated by ultraviolet lamps during irradiation of photopolymerizing resinous materials could cause pulpal damage when a direct technique is used to fabricate provisional restorations.

Evaluating the fracture strength of three different provisional crowns
2014With the advent of new provisional crown materials, it has become imperative to evaluate their strength in order to select the appropriate crown material. This study examined the fracture resistance of three different provisional materials. To simulate oral conditions, the specimens were fabricated in brass molds, ensuring their similarity to premolars.

Relative Clinical Success of Bis-Acryl Composite Provisional Crowns.
Compendium of continuing education in dentistry (Jamesburg, N.J. : 1995), 2018The high demands on the clinical performance of a single-tooth provisional restoration necessitate that said performance be examined. The authors evaluated 24 teeth evaluated. Two test groups received bis-acrylic composite for provisional crowns (n = 12) and a single-unit, self-supporting, malleable, light-curing composite crown (n = 12). Final crowns (
