CONTEXT Resin luting of all-ceramic restorations results in increased performance; however, the strengthening mechanism and the role of the mechanical properties of the resin are not fully understood. OBJECTIVE The aim of this study was to investigate the effect of filler content on the flexural properties of resin luting agents and thereby selecting an appropriate resin luting cement. MATE...

The purpose of this paper was to compare the bond strengths of the self-adhesive luting cements between ceramics and resin cores and examine their relation to the cement thickness. Three self-adhesive luting cements (Smartcem, Maxcem, and G-CEM) and a resin cement (Panavia F 2.0) for control were used in the paper. The thickness of the cements was controlled in approximately 25, 50, 100, or 200...

The major disadvantage of cement-retained implant-supported fixed partial dentures (FPDs) is difficulty in retrievability. The retentive strengths of the provisional luting agents usually employed in these cases are therefore an important consideration. This study evaluated the cement failure loads of 4 provisional luting agents used for the cementation of FPDs supported by 2 implants or 4 impl...

OBJECTIVES The aim of this study was to assess the influence of various ceramic thicknesses and luting agents on color variation in five ceramic systems. METHODS Fifteen disc-shaped ceramic specimens (11 mm diameter; shade A3) were fabricated with each of the six veneering ceramics tested, with 1, 1.5, or 2 mm thickness (n=5). Resin composite discs (Z-250, shade C4) were used as bases to simu...

The choice of luting agents contributes a significant role in retention of cement retained implant restorations and their precise tensile behaviour needs to be investigated further. The aim of present study is to estimate and compare the difference in tensile bond strength between implant abutments and all ceramic restorations luted with four luting agents. An experimental, single blinded, in-v...

Background and Aim: To investigate the radiopacity of different luting, lining and filling dental cements used in prosthetic dentistry in comparison with human and bovine dental hard tissues. Material and methods: Eight cylindrical samples of each material (6 x 1 mm) were prepared from Aqualox (APC), Durelon (DE) and Adhesor Carbofine (ACF) zinc polycarboxylate cements, Cavex zinc oxide eugenol...

The aim of the current study was to evaluate the influence of polycarboxylate temporary cement remaining on the dentin surface on the bond strength of a composite luting system. An acrylic resin plate was luted to bovine dentin with a polycarboxylate temporary cement (HY-Bond Temporary Cement Hard, HYB). The temporary cement was not used for the control groups. After removing the temporary ceme...

OBJECTIVE The aim of the present clinical longitudinal study was to observe, over 10 years, the prognosis of abutment teeth restored with fixed prostheses retained by glass ionomer luting cements and one conventional zinc phosphate cement. METHODS Three dentists prepared 135 abutment teeth in 61 patients to retain 81 fixed prostheses. The prostheses were retained by two glass ionomer luting c...

OBJECTIVE The purpose of this study was to assess the push-out bond strength of glass fiber posts to root dentin after cementation with glass ionomer (GICs) and resinmodified glass ionomer cements (RMGICs). MATERIAL AND METHODS Fifty human maxillary canines were transversally sectioned at 15 mm from the apex. Canals were prepared with a step back technique until the application of a #55 K-fil...

Objectives: To evaluate the microleakage and marginal gap of various luting materials after cementing ceramic crowns. Methods: Cervical margins of human molars were designed as circular chamfers. Cementation of full-contour ceramic crowns was conducted with zinc-phosphate cement (Harvard cement), resin cement (Panavia F 2.0) and self-adhesive resin cements (RelyX Unicem, BifixSE, MaxCem Elite, ...
