A dental implant screw for holding an abutment on a dental implant includes a head and a shaft. A proximal end of the shaft is coupled to the head. The shaft includes a threaded section, an outwardly tapered section leading into a recessed section, and a stop section directly between the outwardly tapered section and the recessed section. The recessed section is directly between the head and the stop section. The threaded section is directly adjacent a distal end of the shaft and is configured to engage threads of an internally threaded bore in the dental implant to hold the abutment on the dental implant.
