“…The cemented crowns were pulled off along the path of insertion with a crosshead speed of 0.5 mm/ minute. The forces required for dislodgment of the crowns were recorded in N. (16) Retention of crowns constructed over dies with 12˚ convergence angle showed significantly higher retention than those over 20˚. This could be attributed to the increased friction and increased surface area for less taper prepared dies.…”

Purpose. The purpose of this study was to evaluate the retention of cubic zirconia crowns with two occlusal convergence preparations and cementation with two resin cements. Materials and methods. 28 dies were divided according to the convergence angles into two main groups. Group (1): 20° (n=14) Group (2): 12° (n=14) Each group was subdivided according to resin cement used into two subgroups. Subgroup A: RelyX Unicem (3M/ESPE, USA) (n=7) Subgroup B: Panavia v5 with clearfil primer plus (Kurary, Japan) (n=7) Two stainless steel master dies were prepared by a milling machine to simulate all ceramic full coverage crown preparation of a maxillary premolar. Each Steel die was machined with height 5.5 mm and two planes occlusal reduction with palatal cusp bevel. The external diameter of the cylinder was 7.5 mm. one die was prepared with 12˚ and the other with 20˚ occlusal convergence angle. Impressions of the main master dies were taken and poured using a non-shrink epoxy resin material. The crowns were cemented. Instron universal testing machine was used to test the retention. The cemented crowns were pulled off along the path of insertion with a crosshead speed of 0.5 mm/minute. The forces required for dislodgment of the crowns were recorded in N. Data were statistically analyzed using one-way ANOVA and many comparisons were made using .Tukey's test at p<0.05. Results. Retention of the zirconia crowns was significantly affected by the occlusal convergence and by the type of resin cement. Self-etching resin cement showed a higher significant result in comparison to self-adhesive. Retention values with occlusal convergence 12° was highly significant with both cements Conclusions. The Retention of cubic zirconia ceramics varied significantly depending on the type of resin cement and degree of occlusal convergence of the preparation.

“…The frictional resistance between the prepared tooth and crown is also an important factor, compared to pronounced taper of approximately 10°, using a low taper angle of approximately 6° might have resulted in frictional retention of crown regardless of the type of luting cement used. [1825] Another major factor to be considered is the flat occlusal reduction carried out in the current study, in oppose to the normal anatomical preparation. The bond strength values were significantly higher when a tooth was prepared anatomically as compared to a flat occlusal surface.…”

Aim:The aim of this study was to evaluate and compare the tensile bond strength of zirconia copings subjected to three different surface treatment methods and cemented with three different luting agents.Materials and Methods:Seventy-two extracted maxillary premolar teeth were prepared to receive zirconia copings milled using computer-aided design/computer-aided manufacturing technology, which were divided into 9 groups of 8 specimens each. Three surface treatment protocols such as hydrofluoric acid etch treatment, air abrasion with 110-μm aluminum oxide (Al2O3), and tribochemical silica coating (Rocatec) treatment were carried out, and copings were cemented with three luting agents such as resin-modified glass ionomer cement (RelyX luting 2), 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP) resin cement (Panavia F 2.0) and 4-methacryloxyethyl trimellitic acid (4-META) resin cement (G-Cem). Tensile bond strength of the copings was tested in a universal testing machine. Zirconia copings fabricated on the prepared extracted tooth. After the three surface treatments and cementing the zirconia crowns with three luting agents tensile bond strength is tested. The mean and standard deviations (SD) were calculated for the nine groups using one-way ANOVA, followed by Tukey–Kramer post hoc using the SPSS software.Results:The ANOVA test showed that the measured mean bond strength values were 4.22 MPa (tribochemicalsilica coating and MDP resin), 2.71 MPa (air abrasion and MDP resin), 2.61 MPa (tribochemical treatment with META), and 0.66 MPa (RelyX with air abrasion). According to the pairwise comparison of Tukey's honestly significant difference test, significant differences were exhibited among all the groups (P < 0.05).Conclusion:Tribochemical silica coating in combination with 10-MDP and 4-META adhesive resins provided the maximum bonding for zirconia copings.

“…Shear, tensile, microtensile or retention tests, are commonly employed to determine the bonding performance of a luting cement [ 37 , 38 , 39 , 40 , 41 ]. The retention test was employed by many researches, where the cemented restoration is subjected to axial dislodging forces till failure [ 39 , 42 , 43 ]. The purpose of this in-vitro investigation was to evaluate the influence of hot acids chemical pre-treatment and the cement type (Panavia SA cement (Kuraray Noritake Dental Inc., Okayama, Japan) plus and G-CEM LinkForce cement (GC America Inc., Chicago, IL, USA) on the retention of monolithic zirconia restoration.…”

Background: The aim of this study was to test the impact of hot acids etching and two types of adhesive cement on the retention of zirconia crowns. Methods: Forty maxillary premolars were prepared, and zirconia crowns were designed and fabricated with proximal extensions, then divided into 4 groups (n = 10). Group AP; the crowns were air-abraded and cemented using Panavia SA Cement. Group AL; the crowns were air- abraded and cemented using GC LinkForce. Group AHP; the crowns were air-abraded, etched with the hot acids (48% hydrofluoric acid and 69% nitric acid), and cemented using Panavia SA Cement. Group AHL; the crowns were air-abraded, etched with the hot acids, and cemented using GC LinkForce. Each zirconia crown was pre-treated and bonded to its corresponding tooth. After thermocycling (5–55 °C/10,000), the retention test was performed and the load required to dislodge the crown was reported in Newton (N), and mode of failure was recorded. The retention strength (MPa) was calculated for each tested variable and statistically analyzed. Results: Group AHP showed the highest mean value of the retention strength, followed by group AP then group AHL. Group AL showed the lowest value. A statistically significant effect (p = 0.001) of the hot acids etching on the retention of zirconia crown was found. Also, there was a significant effect (p = 0.000) of the cement type. The interaction between surface treatment and the cement type has no significant impact (p = 0.882). The main mode of failure for Panavia SA Cement is mixed mode of failure, while for G-CEM LinkForce is adhesive failure. Conclusions: Hot acid etching pre-treatment improved the retention of zirconia crown. Usage of Panavia SA Cement with hot acids etching is effective can be used for adhesive cementation of zirconia crown.
