“…The present study is the first reporting the bonding effectiveness between PV5 and Y-TZP ceramic after NTP treatment. Although luting resins containing 10-MDP have demonstrated good bonding performance in vitro studies [34,40,41], studies demonstrated that this monomer appeared hydrolytically unstable in water [42], and an acidic monomer causes a low degree of conversion and weak bonding compared to Panavia V5, which does not contain 10-MDP in the cement [28]. Analysis of fractured interfacial zone shows a predominance of mixed failures for all experimental groups, which might be related to efficient bond strength.…”

Objective: This study investigated the influence of different surface treatments on zirconia surface energy, roughness and microshear bond strength. Material and Methods: Forty eight slices of Yttria-stabilized tetragonal zirconia polycrystal (Y-TZP- VITA In-Ceram® YZ for inLab®) (6.4 x 3.2 x 1.6 mm) were divided into 3 groups according to the surface treatment (n = 16): YTZP_control -untreated; YTZP_plasma -surface treatment with non-thermal oxygen plasma; YTZP_primer - coating with ceramic primer. Surface energy (n = 6) was measured with a goniometer; and surface roughness (n = 10) was analyzed with a 3D profilometer were performed over zirconia surface. On the same specimens of surface roughness, on the treated zirconia's surface, resin cement (PANAVIA V5 - Kuraray Noritake Dental) was built up by inserting the resin cement into Tygon tubes (1 mm of internal diameter X 1 mm length). After 24 h storage, microshear test was assessed. Data were analyzed by one-way ANOVA and Tukey post-hoc test (p < 0.05). Results: Non-thermal oxygen plasma treated specimens exhibited higher statistically significant surface energy (p = 0.00) and bond strength (p = 0.00) when compared to control and primer groups. Roughness test (p = 0.897) could not detect statistical difference among the tested groups. Conclusion: Non-thermal oxygen plasma should be a suitable alternative for zirconia surface treatment prior to luting hence it improved microshear bond strength and provided higher surface energy without affecting surface roughness. Keywords Adhesion; Non-thermal plasma; Surface treatment.

“…For RUN results were inverse, which might be explained by a higher amount of unreacted phosphoric acid ester groups, resulting in a higher degree of water up-take and thus an increased CS. Higher sorption was previously recorded for RUN for autopolymerized specimens [ 9 ]. Aging of autopolymerized specimens significantly decreased CS for MLA and PV5 due to a degradation of the material that might be due to a lower degree of polymerization than for the light-cured specimens.…”

“…Values of RUN and RUL were increased after aging. RUL and RUN previously presented high sorption that might have been responsible for increasing their strength after thermal cycling [ 9 ]. Light-cured specimens correlated linearly before and after aging and were therefore less susceptible to aging than autoplymerized specimens.…”

“…Resin composite cements consist of three components: a polymer matrix, fillers and silanes that connect organic and inorganic phase [ 5 – 8 ]. These single components and their respective microstructure define the properties of the resin composite cement such as elasticity, hardness, strength and thermal as well as chemical stability [ 6 , 9 , 10 ]. To bond to the tooth substance, adhesive resin composite cements require the application of an acidic agent plus a priming system.…”

BackgroundResin composite cements are used in dentistry to bond ceramic restorations to the tooth structure. In the oral cavity these cements are subjected to aging induced by masticatory and thermal stresses. Thermal cycling between 5 and 55 °C simulates the effect of varying temperatures in vitro. Purpose of this study was to compare indirect tensile to compressive strength of different cements before and after thermal cycling. The effect of the curing mode was additionally assessed.MethodsIndirect tensile strength and compressive strength of 7 dual-curing resin composite cements (Multilink Automix, Multilink SpeedCem, RelyX Ultimate, RelyX Unicem 2 Automix, Panavia V5, Panavia SA Plus, Harvard Implant semi-permanent) was measured. The specimens were either autopolymerized or light-cured (n = 10). The mechanical properties were assessed after 24 h water storage at 37 °C and after aging (20,000 thermo cycles) with previous 24 h water storage at 37 °C.ResultsIndirect tensile strength ranged from 5.2 ± 0.8 to 55.3 ± 4.2 MPa, compressive strength from 35.8 ± 1.8 MPa to 343.8 ± 19.6 MPa.ConclusionsThermocyclic aging of 20,000 cycles can be considered a suitable method to simulate the degradation of indirect tensile strength but not compressive strength of resin composite cements. The effect of thermocycling and the curing mode on the resin composite cements is material dependent and cannot be generalized.

“…Ich zaletą jest uproszczona procedura kliniczna oraz skrócenie czasu zabiegu. 15 Chociaż potencjał adhezyjny cementów żywicznych wraz z hydrofilowością i sorpcją są krytycznymi parametrami, i większość badań skupia się właśnie na nich, 8,[15][16][17] to również właściwości mechaniczne są ważne dla klinicznej trwałości uzupełnienia protetycznego.…”

Wstęp. Wybór określonego cementu protetycznego powinien być dokonywany w oparciu o warunki kliniczne, rodzaj wykonanego uzupełnienia protetycznego, jak również poprzez znajomość właściwości cementów protetycznych. Pojawienie się w ostatnich latach nowych cementów na bazie żywic (samoadhezyjnych, samotrawiących) o odmiennym składzie i mechanizmie wiązania skłania do porównania właściwości mechanicznych ww. cementów. Cel pracy. Porównanie właściwości mechanicznych wybranych cementów żywiczych.
