Crown retention and flexural strength of eight provisional cements
The Journal of Prosthetic Dentistry, 2007Few studies have compared the retention of resin-based and zinc-oxide noneugenol provisional cements. Crown retention testing is difficult and variable; therefore, a simpler method of testing by using flexural strength is indicated.The purpose of this study was to measure the retention of base metal alloy castings to dentin provided by 8 provisional ...

Colour stability of provisional crown and bridge restoration materials
British Dental Journal, 1998In an in vitro study to determine the colour stability of provisional restoration materials, the PMMA synthetics Trimm and Cronsin and the bis-acrylic composites Protemp Garant, Protemp Garant NF, Protemp II and Provipont DC were investigated.The colour changes of the cylindrical untreated samples were measured in comparison with samples after 24 and ...

Chairside provisional implant crown construction: a clinical technique
Dental Update, 2022Provisional restorations provide numerous advantages during dental implant treatment including manipulation of the peri-implant soft tissue contour to optimise the aesthetic outcome. Chairside construction expedites this stage of the treatment to a single visit for the benefit and convenience of both the dental practitioner and patient.

The Journal of Prosthetic Dentistry, 2006
In immediate implant loading, it is important to keep provisional restorations in place during early-phase healing. Current luting agents for provisional restorations may provide inadequate retention, creating a clinical challenge.This study compared the retention of provisional autopolymerizing acrylic resin implant-supported single restorations with ...

Micro-CT analysis of 3D printed provisional crowns fitting
Technology and Health Care, 2023BACKGROUND: The provisional crowns (PR) play an important role during the course of fixed prosthesis treatment. The fitting of PR varies and depends on various factors. OBJECTIVE: The aim of the study was to evaluate the marginal and internal fit of PR produced by three-dimensional (3D) printing technique and to compare those with PR made by the ...

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

Effects of relining on long-term marginal stability of provisional crowns
The Journal of Prosthetic Dentistry, 1995Provisional resins crowns are commonly placed to protect prepared teeth, but the marginal adaptation of interim crowns has always been a problem. These experiments examined the effects of thermocycling and occlusal loading on relined and unrelined polymethyl methacrylate resin transitional crowns.

Use of a Novel Resin Composite Crown as a Long-Term Provisional
Dental Update, 2009Crowns may be indicated to restore teeth where there is substantial tooth substance loss from caries or trauma, but it is not always appropriate to place the substantive restoration without reviewing the prognosis of the tooth under treatment for a time. In such cases, the placement of a long-term provisional restoration may be indicated.

Fabrication of a New Crown and Provisional to an Existing Removable Partial Denture
Journal of Prosthodontics, 1995A method of fabricating a new crown to an existing removable partial denture is described. A press‐form plastic shell made from the diagnostic cast provides the outer contours for the abutment tooth, while an acrylic resin coping is fabricated on a die to provide accurate internal adaptation. The acrylic resin coping is seated on the prepared abutment.

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 ...
