The predictability of dental implants has introduced a significant change in treatment planning and treatment of fully and partially edentulous patients over the past three decades. Even though there are studies investigating the different drilling protocols, little or no data is available regarding the effect of drilling on malposition of the first molar implant placement. In this poster, surgical and restorative considerations such as implant length and drill length, drill length and diameter, straight implant vs. tapered implant, profile drill/twist drill/self-tapping feature, are discussed. A novel surgical drill set to efficiently place implants is introduced. 
A preliminary study done on 11 patients in New York dental University on implant angulation of posterior mandibular implants (#30, 19) shows the following results: • 63% of cases of implants were distally placed .
• 12% of cases of implants were in middle. 
• 25% of cases of implants were is mesially placed. 
Conventional drill systems in the mandibular first molar area cause implant tilting and malposition of implant due to too short shank or too long shank. 
• New set of drills allow guide and profiling, does not need drill extender.
