The implant was first inserted into the osteotomy until it reached the end ofthe prepared site. The implant was then slowly ad- vanced until the sinus floor was penetrated for approximately1mm.Aperiapicalradiographwas performed in orderto determinewhetherthe im- plant had penetrated the sinus floor. A saline sy- ringe with 2–3 cm3 of a 0.9% sterile saline solu- tion was connected to the implant through the tubing port.Withthis system,thetube connector iseasilyassembledontheimplant,allowinginjec- tion offluidswith a standard Luerlock connector.
