Journal of Dental Research, 1980
A rheometer has been developed to simulate the extrusion of luting cement from beneath a full crown during seating using clinically realistic shear rates. Five luting cements were studied, and differences in rheological behavior were illustrated. These measurements demonstrate the importance of consideration of the effects of shear rate on viscosity ...

The properties of polymerizable luting cements
Journal of Oral Rehabilitation, 1999The properties of a polyacid‐modified composite resin and two resin‐modified luting cements have been studied. The polyacid‐modified composite resin had the slowest setting reaction and, in this respect, it did not conform to the current international standard for luting cements.

In vivo disintegration of luting cements
The Journal of the American Dental Association, 1987The in vivo disintegration of luting cements was determined at 6- and 12-month intervals in two test series of 20 participants each. Four cements were inserted in the wells located in the mesial and distal surfaces of cast crowns. Glass ionomer, silicophosphate, polycarboxylate, and zinc phosphate cements prepared with recommended powder/liquid ratios ...

Mechanical properties of dental luting cements
The Journal of Prosthetic Dentistry, 1999Dental luting cements fail by microcrack formation and bacterial ingress or by gross failure and crown dislodgment. Both of these failure modes are related to mechanical properties and deformation.This study evaluated those mechanical properties of cements. METHODS AND MATERIAL.

Film thickness of dental luting cements
Dental Materials, 1986Abstract The film thickness as a function of time after start of mixing was measured for several dental luting cements (one zinc phosphate, 2 polycarboxylate and 3 glass ionomer cements) with 2 different methods, i.e., between 2 plane plates as used to control film thickness in several specifications/standards (Method 1), and in a crown-tooth model ...

Dental luting cements have in general been exclusively designed for the natural tooth, with features that allow for reduction in caries, adhesion to natural tooth tissues, and radiographic appearance often related to dentine. Although many of these properties are redundant when considering restoring dental implants, studies show clinicians frequently ...

Conversion of dual cure luting cements
Journal of Oral Rehabilitation, 1995summary This investigation determined the efficiency and rate of cure of polymeric luting agents when cured under manufacturers' instructions with the appropriate visible light source, and under conditions where light was excluded and curing was reliant on the chemical reaction only.

Destructive Stresses in Adhesive Luting Cements
Journal of Dental Research, 1991In this study, curing shrinkage stress development was monitored in a glass-ionomer and a BisGMA composite luting cement adhesively placed at film thicknesses ranging from 30 to 200 μm. The nature and magnitude of the stress development depended greatly on the formulation and film thicknesses of the lute.

The influence of temporary cements on dental adhesive systems for luting cementation
Journal of Dentistry, 2011This study tested the hypothesis that bond strength of total- and self-etching adhesive systems to dentine is not affected by the presence of remnants from either eugenol-containing (EC) or eugenol-free (EF) temporary cements after standardized cleaning procedures.Thirty non-carious human third molars were polished flat to expose dentine surfaces ...

Fracture toughness of resin-based luting cements
The Journal of Prosthetic Dentistry, 2000The introduction of resin-modified glass ionomer cements has expanded the choices of luting cements available to the clinician; however, few independent studies are available on the fracture toughness of the currently available resin-modified glass ionomer luting agents compared with the composite cements.This investigation evaluated the relative ...
