Use of Vitremer Core Buildup/Restorative Cement (3M Dental Products Division) as a luting cement for orthodontic bands and space maintainers was described in 1994. For use as a luting agent, the restorative cement is mixed with a slightly lower powder liquid ratio so the blend is more fluid than one used for a dental restoration. A chief advantage of using Vitremer Restorative Cement for luting...

The purpose of this study was to evaluate the effects of both marginal fit and cementing with different luting agents on the microleakage of all-ceramic crown systems. Thirty-six extracted upper central incisors were prepared for full-coverage crowns and were divided into three groups. Group 1: CAD/CAM-fabricated ZrO2, Group 2: Heat-pressed lithium-disilicate, and Group 3: Cast Cr-Co copings as...

Background and Aim: Changing the color of resin luting cements could affect the aesthetic appearance of thin porcelain veneer. The aim of this in vitro study was to evaluate the effect of artificially accelerated aging on color stability of light-cured resin cement and flowable composite as a luting agent through the porcelain veneer. Materials and Methods: This experimental study was carried ...

OBJECTIVES Besides the fixation of the restoration, an important function of dental luting cements is to seal the gap between tooth and restoration. However, as a result of adhesion, curing contraction is hindered, creating stresses. To maintain the seal these stresses neither exceed the bond nor the cohesive strength of the cement. The aim of this study was to evaluate a rather simple model, w...

AIM The objective of this study is to investigate the effect of different luting agents on the fracture strength of Turkom-Cera all-ceramic copings. METHODS AND MATERIALS Standardized metal dies were duplicated from a prepared maxillary first premolar tooth using non-precious metal alloy (Wiron 99). Thirty Turkom-Cera copings of 0.6 mm thickness were then fabricated. Three types of luting age...

No studies are available that evaluate the retention of disilicate crowns according to different cementation procedures. The purpose of this study was to measure the retention of lithium disilicate crowns cemented using two different cementation systems. Twenty extracted mandibular premolars were prepared. Anatomic crowns were waxed and hot pressed using lithium disilicate ceramic. Teeth were d...

PURPOSE This study compared the influence of two luting cements on the clinical performance of single crowns. MATERIALS AND METHODS Twenty patients received 39 pairs of metal-ceramic and Procera crowns cemented with zinc phosphate and resin-modified glass-ionomer luting cement (Vitremer) in a split-mouth randomized pattern blinded to the recipient. The crowns were examined immediately after c...

Aim: Mechanical characteristics of tooth preparation along with luting agents are significant entities on the maintenance of fixed dental prostheses. This study aimed at assessing the retention of complete metal crowns luted with two different luting agents using two different preparation height. Methods: Forty human maxillary premolars were selected and prepared to receive complete metal crown...

AIMS To assess and compare the retentive strength of two dual-polymerized self-adhesive resin cements (RelyX U200, 3M ESPE & SmartCem2, Dentsply Caulk) and a resin-modified glass ionomer cement (RMGIC; RelyX Luting 2, 3M ESPE) on stainless steel crown (SSC). MATERIALS AND METHODS Thirty extracted teeth were mounted on cold cured acrylic resin blocks exposing the crown till the cemento-enamel ...

BACKGROUND Moisture sensitivity and dissolution has been a known drawback of glass ionomer cement (GIC). When used as a luting agent for cementation of casted indirect restoration, the exposed cement at the margins is often a primary factor for marginal leakage and consequent failure of the restoration. The following in vitro study was planned to evaluate the effect of a marginal sealant on GIC...
