PURPOSE This study investigated the effects of luting cement type and thickness on the stress distribution within all-ceramic crowns using finite element analysis. MATERIALS AND METHODS An all-ceramic crown restoration of the mandibular right first molar was prepared according to standard dental processes and scanned using micro-computed tomography. Eight 3D FE models were then developed that...

A variety of luting cements are available for use with orthodontic bands. This in vitro study was conducted to evaluate the force required to cause debanding when zinc phosphate, polycarboxylate and glass ionomer cements are used as the luting agents; and to determine whether sandblasting the inner surface of orthodontic bands affects the force required to deband. The data were obtained by deba...

This study investigated the effects of the cement type and the water storage time on the push-out bond strength of a glass fiber post. Glass fiber posts (Fibrekor, Jeneric Pentron) were luted to post spaces using a self-cured resin cement (C&B Cement [CB]), a glass ionomer cement (Ketac Cem [KC]) or a resin-modified glass ionomer cement (GC FujiCEM [FC]) according to the manufacturers' instruct...

The selection of an appropriate luting agent for final cementation of fixed restorations is no longer an easy decision. The numerous materials from which restorations can be fabricated demand a thorough knowledge of not only the material(s) they are made of but also knowledge of the properties of luting agents. No longer can zinc phosphate cement be used for all fixed restorations that need cem...

To evaluate the interactive influence of adhesive materials and surface treatments on bond strength of zirconium oxide ceramics, six types of adhesive resin cements (RelyX ARC (RA), Super-Bond C & B (SB), Linkmax (LM), Panavia Fluoro Cement (PF), Bistite II (BT), and Imperva Dual (ID)), three types of resin-reinforced glass ionomer cements (Xeno Cem Plus (XC), Vitremer Luting (VR), and Fuji Lut...

Abstract Aim The purpose of this study was to compare and evaluate the flexural strength modulus elasticity three adhesive luting cements as a function specimen age, effect storage media, curing through porcelain. Materials Methods Twenty samples fabricated for self-cure resin-modified glass ionomer cement (GIC; RelyX Luting 2, 3M ESPE, United States) were classified group 1, whereas 40 two dua...

Aim: The aim of this study was to compare by means Push-Out test the difference in bond strength two different luting agents with fibre post, and effect anatomical root levels on each cement. Materials Methods: A total 40 freshly extracted maxillary central incisor canine teeth were included study. divided into groups twenty each, assigned Groups B according agent (light cure, dual cure) used c...

PURPOSE To evaluate the degree of conversion (DC) of dual-curing materials used to lute glass-fiber posts in a simulated root canal polymerized by two different modalities. METHODS Artificial root canals were used to simulate a clinical condition to lute 45 posts by three different dual curing luting cements (Calibra, Multilink Automix and Variolink II). Two light cure modalities were chosen ...

OBJECTIVES The aims of this investigation were to clarify the effects of finishing-time and 24 h water-storage on mechanical properties and marginal adaptation to dentin of seven modern luting cements, representing three chemical types. METHODS Bistite II, Chemiace II, Compolute, XenoCem, PermaCem, Fuji Cem and Fuji Plus were investigated with specimen sub-groups (N=10) for each property meas...

OBJECTIVES Based on a maxillary premolar restored with laminate veneer and using the 3-D finite element analysis (FEA) and μCT data, the aim of this study was to evaluate the influence of different types of buccal cusp reduction on the stress distribution in the porcelain laminate veneer and in the resin luting cement layer. METHODS Two 3-D FEA models (M) of a maxillary premolar were built fr...
