Post-cementation sensitivity of bridges cemented with different adhesive resin cements

Journal of Clinical and Experimental Dentistry
Post-cementation sensitivity remains a common clinical concern in fixed partial dentures (FPDs), with variations in adhesive resin cement formulations influencing patient discomfort and long-term success. This study aimed to compare post-cementation sensitivity in FPDs cemented with three different resin cements: self-adhesive resin cements, resin ...

Effect on mechanical properties and stress strain characteristics of normal and high strength concrete at elevated temperature

Journal of Building Materials and Structures, 2020
High strength concrete (HSC) has some disadvantages such as brittleness and poor resistance to fire. Fire exposure affects the concrete in way that the disintegration of concrete starts and a severe surface spalling occurs at very high temperatures ...

CEMENT TLA

, 2019
Da bi se na nekoj podlozi nešto sagradilo potrebno je da podloga ima određena svojstva primjerena gradnji. Danas se za pripremu neadekvatne podloge za gradnju koriste dva načina. Jedan podrazumijeva da se podloga za izgradnju u potpunosti promjeni, a drugi je da se postojećoj podlozi poboljšaju svojstva.

Adhesive cements and cementation.

Journal of the California Dental Association, 1993
Luting cements are a critical, but weak, link between fixed prostheses and their supporting tooth structures. Luting cements have relatively poor physical properties compared to bulk restorative filling materials, but they must fulfill an additional series of requirements such as low film thickness.
