Microleakage of different sealing materials in access holes of internal connection implant systems

Comparison of three in vitro implant leakage testing methods

“…), spectrophotometric determination of dye penetration (Park et al. ) and the gas permeability test (Torres et al. ).…”

Different sealing materials preventing the microbial leakage into the screw‐retained implant restorations: anin vitroanalysis byDNA checkerboard hybridization

“…It has been reported that various materials have been used filling the screw access channels of the abutments of screw‐retained implant‐supported restorations (Moráguez & Belser ; Park et al. ; Cakan et al. ; Cavalcanti et al.…”

“…Park et al. () investigated the occurrence of fluids leakage through this pathway testing different sealing materials, including cotton pellet and gutta‐percha. They evaluated the penetration of basic fuchsin into the internal part of the implants after loading simulation.…”

“…Recently, Park et al. () evaluated the levels of fluids leakage through the access holes of screw‐retained implant prostheses sealed with cotton, silicone, vinyl polysiloxane, or gutta‐percha. Vinyl polysiloxane and gutta‐percha showed the lower levels of leakage.…”

Partially Biodegradable Distraction Implant to Replace Conventional Implants in Alveolar Bone of Insufficient Height: A Preliminary Study in Dogs

“…Obvious apical bone infection was not observed in this study. An abutment with high fitting accuracy and sealing material will be needed after the removal of the distraction screw …”
