[Influence of retainer design on fixation strength of resin-bonded glass fiber reinforced composite fixed cantilever dentures].

Fiber-reinforced composite (FRC) fixed partial dentures (FPD) have become an accepted part of the restorative dentist's armamentarium. The aim of this study was to evaluate in vitro the influence of retainer design on the strength of two-unit cantilever resin-bonded glass FRC-FPDs. Four retainer designs were tested: a dual wing, a dual wing + horizontal groove, a dual wing + occlusal rest and a step-box.

[The impact of ultrasonic dental hygiene procedures on the bonding strength of restorations].

Ultrasonic calculus scaling has become a common oral hygiene procedure in patients with composite restorations, dental veneers, orthodontic brackets. The aim of the study was to evaluate in vitro the influence of the EMS-ultrasonic system scaling on the flowable composite bond strength to the tooth enamel, dentine, and e-max ceramic. The samples were divided into three groups: 1 group (composite bonded to enamel), 2 group (composite bonded to dentine), 3 group (composite bonded to e-max ceramic).

[Review of conservative replacement methods of the included minor defects of dentitions].

The paper reports the review of replacement methods of one absent tooth. The study was an assessment of prosthetic work in 275 patients with similar diagnosis. The aim of the study was to compare the indications for different fixed appliances with adhesive bonding on the example of schematic clinical situations.
