“…A standardized test for determining the retention strength of crowns to abutments is currently not available. In this study, a cyclic rate of 80 cycles/min was used 21 . Chewing rate differs from one person to another and there is variation in the chewing rate of the same person.…”

These results might suggest TempBond luting agent as the material of choice for provisional cementation because it allows easier removal of the prosthesis and maintains enough retention to prevent loosening of the restoration. The clinical implication is that the effect of cyclic load on the strength of the cements is different, an important factor in selection of a cement. ImProv had the highest retentive value before and after the two cycles, and TempBond had the lowest. UltraTemp had the highest percentage of retentive value lost. TempBond had no significant loss under loading even though initially it was the weakest.

“…Previous studies 8,23,24 included the reuse of paired abutments and castings for tensile testing. Repeated cementation of the dental castings and the surface oxidation were not a concern, because it has been shown that these factors do not significantly affect the tensile bond strengths of luting agents 25,26 …”

“…In this study, these factors were the same for all specimens investigated. Repeated cementation of dental castings has been shown that it did not significantly affect the tensile bond strength of luting agents [15] Breeding et al [2] compared tensile bond strengths of three dental luting agents after cementing casted restorations to both human teeth and machined titanium implant abutments and reported no significant differences between retentive values for the natural abutments and the machined metal implant abutments for any of the luting agents tested.…”

Retrievability of cemented implant-supported fixed prosthesis is desirable.Objectives: Compare retentive force of several provisional luting agents when used with cemented superstructures and one implant system. Methods:Five ITI solid screw implant fixtures and solid conical abutments with 6º taper were used. Five metal ceramic crowns were fabricated and cemented with five different provisional luting agents named Tem Bond, Temp Bond NE, Fynal, TNE, and ImProv. Tensile retentive force necessary to debond each casting was measured 30 minutes after cementation in a dry condition (n=10) and after storing and thermocycling for 72 hours (5-55ºC) in artificial saliva (n=10). Mean and standard deviation of retentive force was calculated for all cements. Data were statistically analyzed using two way analysis of variance at 5% level of significance. Tukey's post hoc test was performed. Statistical software (SPSS, v.16) was used for data analysis.Results: This study provided a rank order of different provisional luting cements according to their ability to retain crowns. Storing and thermocycling of specimens in artificial saliva for 72 hours caused significant reduction in the retentive values of all provisional luting agents investigated. Conclusion:The results may help the clinicians for selecting luting agent, retentive enough to withstand occlusal forces, yet weak enough to allow easy retrieval of cement-retained fixed restorations.

“…7,8 The possibility that ultrasonic instrumentation may cause fragility of the zinc phosphate cement has been widely accepted for intraradicular retainers 9-11 but little is known about its action on crowns and fixed partial dentures. 12,13 Thus, the objective of the present study was to determine the in vitro effect of ultrasonic instrumentation on the bond strength of crowns cemented with a zinc phosphate agent to teeth receiving standardized preparations compared to that observed on teeth not submitted to instrumentation.…”

Several studies have reported the benefits of sonic and/or ultrasonic instrumentation for root debridement, with most of them focusing on changes in periodontal clinical parameters. The present study investigated possible alterations in the tensile bond strength of crowns cemented with zinc phosphate cement to natural teeth after ultrasonic instrumentation. Forty recently extracted intact human third molars were selected, cleaned and stored in physiologic serum at 4°C. They received standard preparations, at a 16º convergence angle, and AgPd alloy crowns. The crowns were cemented with zinc phosphate cement and then divided into four groups of 10 teeth each. Each group was then subdivided into two subgroups, with one of the subgroups being submitted to 5,000 thermal cycles ranging from 55 ± 2 to 5 ± 2°C, while the other was not. Each group was submitted to ultrasonic instrumentation for different periods of time: group 1 -0 min (control), group 2 -5 min, group 3 -10 min, and group 4 -15 min. Tensile bond strength tests were performed with an Instron testing machine (model 4310). Statistical analysis was performed using ANOVA and Tukey's test at the 5% level of significance. A significant reduction in the tensile bond strength of crowns cemented with zinc phosphate and submitted to thermal cycles was observed at 15 min (196.75 N versus 0 min = 452.01 N, 5 min = 444.23 N and 10 min = 470.85 N). Thermal cycling and ultrasonic instrumentation for 15 min caused a significant reduction in tensile bond strength (p < .05).
