• The round shape of the drill prevents damages to the mandibular nerve
• Safe drilling is possible despite insufficient bone height
• Less chair time thanks to simple drilling sequence
·The tip of 485 drills are round, therefore not damaging the inferior alveolar nerve
·Safe drilling for short implants is possible thanks to the stoppers (1 mm extra room minimizes interference of surrounding bone)
·No damages to nerves despite insufficient bone height of less than 6mm
·2 time drilling is enough in normal bone and hard bone
