All Implants
After good surgical exposure of the bony surface the position for the implant should be determined and a guide hole should be made using our round head burr taken down into the cortical bone to the level of the neck beneath the burr head. Do not attempt to drill deeper with the round burr. Using the guide hole for position, the color-coded drill bits will be utilized to drill the hole to the desired depth. The color-coding on the bits indicates the diameter of the bit.
Almost all drilling (excluding all I6 implants, I5-3.75 & I7-3.75) should commence using the 2.0 mm bit. The bits are used in graduating order to slowly increase the diameter of the implant hole until the desired diameter is reached. This will allow a safe progression and decrease trauma to the surrounding bony structures. The accurate depth of the hole is determined by the length of each particular implant and is indicated by the depth lines around each bit, in order to allow good position of the implant in the bone so that its end is flush with the alveolar ridge.

I2 Protocol
The final diameter of the hole should be one half millimeter smaller than the implant diameter (e.g. for an implant with a diameter of 3.75 mm, the final bit size would be 3.2 mm). Tables 1 & 2 below summarize the final color-coded drill for each implant.

The most efficient method of drilling has been found to be achieved through the use of conical drilling bits.  We highly recommend that our customers acquire the conical drilling bits. The conical drilling bit for each diameter is suitable for every implant length in that diameter.
Where the conical drilling bits are not available, it is possible to achieve the desired tapering of the hole by redrilling with two slighter larger bits taken down to only a partial depth. The first bit, slightly larger than the bit used to reach the desired depth of the implant hole, drills only ~2/3 of the total depth and the second, slightly larger than the first, drills only ~1/3 of depth, thus creating a staged or conical tapered hole. The drilling protocols of tapered holes for different implants are presented in Table 3a.

Where the 2.4 mm conical drill bit is not available, it is possible to use the regular 2.0 mm drill bit instead, but it should be inserted only till the depth line below the nominal one reaches the alveolar ridge. Table 4a summarizes the final color-coded drill for each implant when not using the conical drill bit.
