Temperature rise in pulpal chamber during fabrication of provisional resinous crowns

The Journal of Prosthetic Dentistry, 1997
The 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.

Evaluation of vertical marginal adaptation of provisional crowns by digital microscope

Nigerian Journal of Clinical Practice, 2017
To investigate and compare the degree of vertical marginal discrepancy of four provisional crown materials by digital microscope.A total of 100 provisional crowns were fabricated on standardized resin dies by direct technique of provisional fabrication, using four different provisional materials (n = 25): Provisionals Fabricated by Systemp® c and b II,

Evaluating the fracture strength of three different provisional crowns

2014
With 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), 2018
The 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 (
