Drill Sequence for NaturaLLock Implant System (Ø 4.3 mm, L 13 mm)
Drill Sequence for NaturaLLock Implant System (Ø 4.3 mm, L 13 mm)

Diagram of the initial situation. Surgical procedure for minimally invasive implant placement of a 4.3 x 10 mm implant. We recommend preparing at 800 rpm (contra-angle reduction 10:1) with gentle up and down movements until the planned depth is reached. Ensure that there is constant and adequate cooling using sterile saline solution with all drilling procedures.

Fig. 2
In the first drilling procedure a drill guide Ø 4.3 is placed on the planned region to simulate the ideal position of the implant. Great care should be taken to ensure that there is adequate attached gingival all round the drill guide.

... to the 18 mm mark. This corresponds to a drilling depth of 10 mm in the bone, as the drill guide is 5 mm high and we assume an average mucosal thickness of 3 mm.

The pilot drill Ø 3.0 has a noncutting tip. This enables controlled extension of the 2 mm pilot drill hole to 3 mm.

The implant driver Ø 4.3 is placed on the implant and the implant is rotated using 25 rpm and a maximum torque of 40 Ncm.

Fig. 18
The implant driver has markings on the buccal and lingual to ensure that the implant can be positioned to the optimal alignment

If the bone is too hard and the implant cannot be inserted to its final position, it should be unscrewed and temporarily stored in the sterile packaging. The main drill Ø 4.3, L 8 is then drilled 1 mm deeper than planned. This extends the bone in the crestal region. The implant is then re-inserted.

The abutment of the NaturaLLock implant has been designed so that preparation is no longer required with an ideal position. Before the
impression is taken, a transfer screw is screwed on top of the implant.

Fig. 21
The gingival margin contour is different from tooth to tooth and from mesial to distal. The margin of the restoration should follow this contour to ensure that the biological boundary is not damaged.
