“…This has also been identified in previous studies. It is a well-documented phenomenon that aluminum particles are left over from blasting, despite the cleaning procedure with water rinsing and steam blasting 4,12,18,21) .

Considering previous studies that analyzed the bond between titanium and porcelain, SEM and EDS was used to enable an analysis of the chemical composition and to define the oxide layer 1,18,19) .

Cast, milled and EBM-manufactured titanium, differences in porcelain shear bond strength

The objectives were to analyze the oxide layer generated between titanium and porcelain during firing and compare it in different manufacturing techniques: cast, milled and EBM-technique. Seventy two specimens were manufactured, subdivided according to surface treatment: time of passivation (P) and no time of passivation (NP) before porcelain firing. Specimens from each group were analyzed with scanning electron microscopy: one only fired once, and one subjected to six firings. Remaining specimens were subjected to shear bond strength test. The EBM-produced NP-group had highest mean value (25.0 MPa) and the milled P-group showed lowest mean value (18.5 MPa) when all factors were compared. No significant difference was detected according to time of passivation. SEM showed consistent and well-defined boundary between the different layers. Time of passivation and impact on oxide growth was not detected. The bond strength of porcelain to milled titanium is lower when compared to cast titanium and EBM-produced titanium.

“…The clinical performance of metal-porcelain restorations is usually estimated using mechanical strength tests, which largely focus on the bonding performance between the veneering porcelain and the metal surface 19) . For example, in an SBS test, two materials are loaded in shear until separation occurs; upon failure, bond strength is calculated by dividing the maximum applied force by the cross-sectional area of the bonding surface 20) .…”

Shear bond strengths of veneering porcelain to cast, machined and laser-sintered titanium

The aim of this study was to compare the shear bond strengths (SBS) of cast, machined, and laser-sintered titanium to dental porcelain. Two kinds of dental porcelains (Titankeramik and Triceram) were applied on cast (Tritan), machined (DC-Titan), and laser-sintered (EOSINT) titanium specimens (n=10). SBS test was conducted, and fracture surface analysis was also performed to determine the failure modes. Two-way ANOVA, Student's t-test, and post hoc test were used to analyze the data (p<0.05). Among the titanium specimens, the SBS values of laser-sintered titanium specimens were significantly higher than the machined and cast titanium specimens (p<0.01). Comparison of Triceram and Titankeramik veneering porcelains showed no statistically significant differences in SBS when they were applied on laser-sintered and cast titanium specimens (p>0.05). Specimens in all the test groups exhibited adhesive or combined failure, with the Titankeramik-machined titanium group exhibiting the highest adhesive failure rate (40%). Results showed that porcelain-titanium bond strengths could be improved by using the new laser sintering technique to produce titanium for prosthodontic applications.

“…1,2 Different metal compositions can be used to manufacture their frameworks, such as NiCr, NiCrTi, AgPd, CoCrMo, and Ti, with clinically satisfactory results. However, fracture or chipping of the ceramic veneer is a potential problem for these restorations, 3 with these occurrences reported as the second most likely cause for their replacement, after dental caries.…”

Among the repair systems evaluated, those which use the tribochemical silica-coating procedure can be considered good options for repairing exposed titanium surfaces. Furthermore, the Cojet system's failure mode and stable behavior after water storage seems to indicate its use for a titanium surface repair technique. SUMMARYThis study evaluated the shear bond strength (SBS) and stability of commercially pure titanium (CP Ti)/repair material interfaces promoted by different repair systems. One hundred CP Ti cast discs were divided into five repair system groups: 1) Epricord (EP); 2) Bistite II DC (BT); 3) Cojet (CJ); 4) Scotchbond Multi-Purpose Plus (SB) (control group); and 5) Cojet Sand plus Scotchbond Multi-Purpose Plus (CJSB). The specimens were stored in distilled water for 24 hours at 378C, thermal cycled (5000 cycles, 58-558C) and stored under the same conditions for either 24 hours or six months (n=10). SBS was tested and the data were analyzed by two-way analysis of variance (ANOVA) and Tukey test (a=.05). Failure mode was determined with a stereomicroscope (203). The repair system, storage time, and their interaction significantly affected the SBS (p,0.001). At 24 hours, CJSB exhibited the highest SBS value, followed by CJ. At six months, these two groups had similar mean SBS (p.0.05) and higher means in comparison to the other groups. For both storage times, BT , 2012, 37-3, 253-262 presented the lowest SBS, while the EP and SB groups did not differ significantly from one another (p.0.05). There were no significant differences in SBS between the storage times for the groups EP and CJ (p.0.05). The groups BT, SB, and CJSB showed 100% adhesive failure, irrespective of storage time. The CJSB group showed the highest SBS at both storage times. At six months, the CJ group exhibited a similar SBS mean value when compared to the CJSB group. Water storage adversely affected the groups BT, SB (control group), and CJSB.Considering SBS values, stability, and the failure mode simultaneously, the CJ group showed the best CP Ti repair performance.
