“…A consistent finding is that the least microleakage and the best marginal adaptation are obtained when using a resin cement [ 50 , 61 – 64 ]. These cements are also the least affected by artificial ageing.…”

Aim. The aim of this comprehensive review is to systematically organize the current knowledge regarding the cementation of glass-ceramic materials and restorations, with an additional focus on the benefits of Immediate Dentin Sealing (IDS). Materials and Methods. An extensive literature search concerning the cementation of single-unit glass-ceramic posterior restorations was conducted in the databases of MEDLINE (Pubmed), CENTRAL (Cochrane Central Register of Controlled Trials), and EMBASE. To be considered for inclusion, in vitro and in vivo studies should compare different cementation regimes involving a “glass-ceramic/cement/human tooth” complex. Results and Conclusions. 88 studies were included in total. The in vitro data were organized according to the following topics: (micro)shear and (micro)tensile bond strength, fracture strength, and marginal gap and integrity. For in vivo studies survival and quality of survival were considered. In vitro studies showed that adhesive systems (3-step, etch-and-rinse) result in the best (micro)shear bond strength values compared to self-adhesive and self-etch systems when luting glass-ceramic substrates to human dentin. The highest fracture strength is obtained with adhesive cements in particular. No marked clinical preference for one specific procedure could be demonstrated on the basis of the reviewed literature. The possible merits of IDS are most convincingly illustrated by the favorable microtensile bond strengths. No clinical studies regarding IDS were found.

“…Jest to klinicznie niedostrzegalny fenomen przepływu płynów, bakterii, cząsteczek i jonów pomiędzy ścianą ubytku a materiałem wypełniającym. 21 W celu długoczasowego użytkowania uzupełnienia protetycznego w jamie ustnej oraz ograniczenia przepływu bakterii do miazgi należy zapewnić jak najlepszą adaptację brzeżną, dlatego dokładność przylegania uzupełnienia do filaru ma tak duże znaczenie kliniczne. 12 Każda z przedstawionych w opisywanych badaniach technik (tłoczenia i CAD/CAM) ma swoje ograniczenia.…”

“…This is a clinically unnoticeable phenomenon where fluids, bacteria, particles, and ions flow between the wall of the defect and the filling material. 21 In order to obtain a long-lasting prosthetic restoration in the oral cavity and to limit the flow of bacteria to the pulp, it is necessary to ensure the best possible marginal integrity, which is why the accuracy of adhesion of the restoration to the crown preparation is of such great clinical significance. 12 w celu wykonania koron.…”

Head: prof. dr hab. n. med. Elżbieta Mierzwińska-Nastalska Summary Constant advances in laboratory technology, along with the development of dental materials, have created new opportunities for prosthetic reconstruction of clinical crowns of teeth. The most important factor affecting the possibility of the long-term functioning of a permanent prosthetic restoration in the oral cavity is the precision of its production, including the accuracy of adhesion of the restoration to the abutment. The aim of the study is to review the latest research results concerning the impact of the technology of ceramic restoration production on the accuracy of their adhesion to the structure of the abutment. Among the articles available in the Medline database, those from the years 2011-2018 were selected for the analysis. All chosen articles present a description of in vitro studies and concern the comparison of marginal adaptation depending on the type and method of preparation of the ceramic material.

“…Cement washout and crown dislodgement has been identified as a complication associated with cement retained ISR, particularly when a soluble or provisional cement is placed 24,25 . In addition to provisional cements being susceptible to cement washout, abutment design, mechanical loading and thermocycling may increase microcracking of the cement and microleakage 26,27 . For provisional cements and, in particular, petroleum jelly admixtures, the effectiveness of the sealed interface may be time dependent.…”

Background: Advantages of cross-pin retained implant supported restorations (ISRs) include predictable retrieval and predictable retention. Unlike direct to fixture (DTF) or cement retained restorations, the prosthetic design of a cross-pinned restoration retains gaps at the interfaces between the crown, abutment and cross-pin screw. These spaces permit leakage into the suprastructure and gasket placement has been recommended to prevent this leakage. Methods: Five different gaskets were assessed for their ability to prevent leakage into a cross-pinned ISR. The gaskets tested were: cement admixture on the cross-pin screw; cement admixture on the inner surface of the coping and the cross-pin screw; cement admixture on the inner surface of the coping only; cement admixture placed 1 mm from the margin of the coping and a filler placed in the abutment chimney. Results: Only gaskets which sealed both the cross-pin screw interface and the abutment-crown interface prevented leakage. A filler placed in the abutment chimney prevented leakage into this space but did not prevent fluid accumulating between the coping and abutment. Conservative placement of cement at the margin of the coping failed to prevent leakage. Conclusions: Cement gaskets may effectively prevent leakage into a cross-pinned ISR. However, the use of a cement as a gasket has to be weighed against the issue of predictable retrieval, cement extrusion and incomplete seating.

In vitro evaluation of microleakage of various types of dental cements

Abstract: The investigated dental cements revealed different sealing abilities. The use of resin cement resulted in the percentage of 0 microleakage scores. Due to this feature, the resin cement is to be recommended in everyday clinical practice.
