Useful function of setting a negative V-Factor in the Implastation program

This case is an example of implantation with the help of a surgical guide in a limited bone situation.

The ImplaStation program includes the function of setting negative V-factor, which allows an accurate and non-traumatic preparation of the cortical bone from the maxillary sinus side.

The drill planning manager considers the actual dimensions of the drill and guide sleeve. It allows you to set the drill aperture shift relative to the implant apex (the extreme apical point of the drill is connected with the implant apex).

As a rule, pilot drills have a V-shaped tip, and some implant systems have a flat apical part. For such combinations, drilling have to be done deeper, considering the height of the V-shaped tip (V-factor).

Planning in the positive direction — compensation of the V-factor, in the negative — the drill does not bore the bone to the planned position of the implant apex at a given depth.

In the 16 and 17 areas, subanthral augmentation and implants were performed.

The planning of the operation was made in the ImplaStation program, that you can download for free here.
