Sleeve sizes can be ordered depending on the size of the implant. The sleeve sizes are 3.5 mm, 5.0 mm, and 6.5 mm in diameter: narrow, regular, and wide respectively.
The fixture diameter of 3.5 mm has an extra 0.5 mm due to the widest thread length, while fixture diameter of 4.0 ~ 8.0 mm has an extra 0.4 mm due to the widest thread length. This means 4.5 diameter implant is the widest for the regular drill core as 4.5 mm + 0.4 mm = 4.9 mm.
