Objective: The objectives of this study was to assess the instrument design in comparison to the implant design, compare the initial implant stability obtained using four different osteotomy techniques in low-density synthetic bone, and determine a potential correlation between the insertion torque and initial stability quotient (ISQ). Methodology: According to the osteotomy method employed (n = 10 implants per group), four groups were established: group G1, osteotomy using the suggested drilling sequence; group G2, osteotomy using an undersized compactor drill; group G3, osteotomy using an undersized drill; and group G4, osteotomy using universal osseodensification drills. There were two polyurethane blocks used: block 1, with a medullary portion of 10 pounds per cubic foot (PCF 10), and block 2, pounds per cubic foot (PCF 40). 11 mm in length and 4 mm in diameter tapered implants were employed. Both the ISQ and the insertion torque (IT) were measured. Results: Depending on the method employed for the osteotomy in the two synthetic bone models, differences between the four groups were discovered for IT and ISQ values (p 0.0001). In comparison to block 2, all groups displayed decreased initial stability values in block 1. Conclusion: When compared to beds prepared with universal drills and utilising the drilling sequence prescribed by the manufacturer, undersized osteotomies performed with instruments made specifically for the implant body considerably boosted the initial stability values.
