Within the limitation of the present study, after the offset cyclic tensile and compressive loading, the amount of microleakage from implant–abutment interface was smaller in conical connection than in internal parallel connection.
In the present study, chronological increase of the amount of microleakage was observed in all three groups. This is in consistent with previous studies [5, 13, 15, 16]. Sigmoid curves of microleakage in all groups meant that the amount of leakage was large at the early stage of loading. This was in agreement with previous reports. Harder et al. reported that bacterial toxin leak occurred within 5...
In the present study, cyclic tensile and compressive loading were applied to cantilever superstructure. In the clinical situation, both compressive and tensile force was exerted to implant-supported prosthesis, but no previous study has discussed the microleakage using model study under this situation. In case of conical connection, compressive force may have promoted a higher penetration of the a...
During the experiment, one (EP) and two (IP) abutment screws out of seven samples were fractured. In this case, abutment screw was changed to new one and experimental procedure was re-run.
After the 2000Â cycles of compressive tensile loadings, RTV of abutment screw was measured. There were no statistical differences in the RTV among three groups. Standard deviation was largest in the RTV of EP a...
Three kinds of Nobel Biocare implants were employed in the present study, namely, Nobel SpeedyGroovy WP 5.0 × 15 mm (EP), Nobel Replace WP 5.0 × 15 mm (IP), and Nobel Parallel CC RP 5.0 × 15 mm (CC) (n = 7 each) (Nobel Biocare, Kloten, Switzerland). Implant–abutment connections are external, internal parallel, and internal and conical connection, respectively. Implant was e...
Although promising outcome of implant therapy has been reported, periimplantitis which is known to be one of the most important factors associated with late failure [1] is a serious complication and expected to overcome to obtain successful outcome. It is known that there are some spaces between abutment and implant body which can be a reservoir of microorganisms and other toxic substance [2], and...
There are some spaces between abutment and implant body which can be a reservoir of toxic substance, and they can penetrate into subgingival space from microgap at the implant–abutment interface. This penetration may cause periimplantitis which is known to be one of the most important factors associated with late failure. In the present study, three kinds of abutment connection system, external ...
