There is limited dental literature evaluating the retentive capabilities of luting agents when used between metal components, such as cast metal restorations cemented onto machined metal implant abutments. This study compared the retentive strengths of 5 different classes of luting agents used to cement cast noble metal alloy crowns to 8-degree machined titanium cementable implant abutments fro...

This literature review summarizes the recent research on fiber posts and provides information regarding their bonding to resinous cement or composites, based on the results of original scientific full-papers from peer-reviewed journals listed in Pub Med. The search was conducted evaluating the different materials available for luting fiber posts to radicular dentin. A consistent number of in vi...

This study evaluated the shear bond strengths and etching patterns of seven self-adhesive resin cements to human enamel specimens which were subjected to one of the following surface treatments: (1) Polishing with #600 polishing paper; (2) Phosphoric acid; (3) G-Bond one-step adhesive; or (4) Phosphoric acid and G-Bond. After surface treatment, the human incisor specimens were bonded to a resin...

The purpose of this study was to evaluate hardness (indicator for polymerization) and thickness of two types of resin cement at coronal, middle and apical level of tooth root canal. Ten extracted maxillary incisors were instrumented and post space was prepared for cementation of titanium post. Samples were divided into two groups and each group was cemented either of the two types of resin ceme...

The aim of this study was to evaluate relationship between shrinkage development and early solubility of two commonly used luting materials, a self-adhesive cement (GCem chemical and light cured) and composite resin (Tetric). Linear displacement, shrinkage forces and leaching of UDMA from specimens immersed in 75% ethanol/25% water were measured. The least amount of linear shrinkage (33.0±2.9 µ...

The purpose of this research project was to compare the fit of a retrievable cement-retained implant-supported framework to that of a traditional wax and cast, screw-retained framework and to test the strength of the cemented restoration. Ten telescopic frameworks were luted to gold cylinders with a bis-GMA resin cement. The control group consisted of 10 frameworks fabricated with traditional w...

One important aspect of dental restorations is esthetic. Although ceramic restorations are usually undertaken for esthetic reasons, several factors can affect their results. This study was undertaken to systematically review articles addressing the effect of ceramic thickness and luting cement color on the final restoration color. This systematic review was based on PRISMA (Preferred Reporting ...

The purpose of this study was to evaluate the disintegration of luting agents. An intraoral sample holder was made having four holes of 1.4 mm diameter and 2 mm depth. The holder was soldered onto the buccal surface of an orthodontic band, which was cemented to the first upper molar in 12 patients, average age 26 years. The holes were filled with a zinc phosphate (Phosphate Kulzer), a glass ion...

OBJECTIVES This study aimed to evaluate the vertical discrepancy of implant-supported crown structures constructed with vacuum-casting and Direct Metal Laser Sintering (DMLS) technologies, and luted with different cement types. STUDY DESIGN Crown copings were fabricated using: (1) direct metal laser sintered Co-Cr (LS); (2) vacuum-cast Co-Cr (CC); and (3) vacuum-cast Ti (CT). Frameworks were ...

Background and Purpose: The aim of this study was to evaluate the flexural strength values five luting cements that are commonly used in dental restorations after exposed hyperbaric pressure.
 Methods: Five (polycarboxylate cement, glass ionomer manual-mixed resin two auto-mixed cement) were prepared. (25 x 2 mm3) (n=16 for each) specimens divided into subgroups (n=8) pressure (3 ATM) 20 t...
