Marginal and internal fit of provisional crowns fabricated using 3D printing technology
Technology and Health Care, 2020BACKGROUND: Clinicians routinely provide provisional crowns following teeth preparation. Three-dimensional (3D) printing technology could be used over conventional methods for better fit as lack of adequate fit would result in plaque accumulation, micro ...

Color stability of provisional crown and fixed partial denture resins
The Journal of Prosthetic Dentistry, 2005Provisional resins are used extensively during fixed prosthodontic treatment and exhibit varying degrees of color change/discoloration over time. Data are needed to help predict color stability of provisional resins.The purpose of this in vitro study was to measure the color change of 12 provisional prosthodontic materials after immersion in artificial

Immediate Maxillary Lateral Incisor Implants with Nonocclusal Loading Provisional Crowns
Journal of Prosthodontics, 2007AbstractThis clinical report series describes a treatment modality involving immediately placed dental implants in maxillary lateral incisor sites using noncemented immediate provisional crowns retained with calcinable copings (prosthetic complement used in preparing the metal for the definitive prosthesis).

Marginal fidelity of crowns fabricated from six proprietary provisional materials
The Journal of Prosthetic Dentistry, 1997The most important requirement for an interim crown is suitable marginal adaptation.This in vitro study compared vertical discrepancies of margins for complete crowns made with six provisional materials (Provipont, Protemp Garant, Unifast LC, Triad VLC, Splintline, and Jet).A direct technique was used to fabricate 60 provisional complete crowns on ...

Flexural strength of provisional crown and fixed partial denture resins
The Journal of Prosthetic Dentistry, 2002Provisional prostheses are subject to flexure under function. Selection of the appropriate material for their fabrication is difficult given the limited evidence-based information on the flexural strength of provisional resins.This study compared the flexural strength of 5 methacrylate-based resins and 8 bis-acryl resins used to fabricate provisional ...

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.
