Table 4. Calculated area of the last instrument used in each group and the difference in relation of the implant body area (without threads) and the external area of the implant with the threads.

Group	Total area	Difference 1	Difference 2
G1	168.5 mm2	8.6 mm2	-6.5 mm2
G2	101.2 mm2	-58.7 mm2	-73.8 mm2
G3	128.2 mm2	-31.7 mm2	-46.8 mm2
G4	131.7 mm2	-28.2 mm2	-43.3 mm2

Difference 1 = total area of the instrument–total area of the implant body; difference 2 = total area of the instrument–total area of the implant with the threads.
