Several years ago the Vector system was introduced to the 
European market for ultrasonic periodontal treatment. The manufacturer claimed that the system removed root cementum and periodontal soft tissues less aggressively than hand instruments. Furthermore, the treatment with the Vector system was claimed to be less painful than treatment with conventional systems, as vibrations applied horizontally to the root surface were avoided by a specific oscillation pattern. In addition, by changing the different insert tips of the handpiece, it is possible to use the device not only for periodontal treatment but also in restorative dentistry (i.e. minimal invasive preparation). Several studies assessed the properties of the device, and evaluated its possible benefits especially for periodontal debridement and supportive periodontal care.

Dürr Vector System
- Periodontal Treatment Breakthrough
More than 60% of all adults in the industrial world suffer from Periodontitis. With the Dürr Vector System you gain control of this disease. The Dürr Vector removes biofilm, plaque, calculus, endotoxins and eliminates the causal bacteria quickly and reliably. With Vector you work ergonomically and with a sensitive touch right into the last corner, even in pockets more than 5, 9 or 11 mm deep.
Many dentists tend to view the use of sonic and ultrasonic equipment sceptically, especially when working in subgingival areas. There is too great a danger that instruments, whatever their shape, that are oscillating or swaying in an undifferentiated manner, do more harm than good in the pocket. This is not the case with Vector.
Vector converts the ultrasonic dynamics of 25,000 Hz in such a way that you as a dentist can work in a completely relaxed and non-traumatic manner. Quickly and effectively.
The actively oscillating ring of the Vector functions in a similar way to a hula-hoop. If it is pressed into the horizontal position it moves with exactly 90° deflection vertically.
It is a question of allowing the instruments to oscillate exactly linearly, parallel to the surface of the tooth, without circling, swaying or knocking. With the Vector method you can do practically nothing wrong.
Available soon.

Clinical Experience by Perio:
1. More precice to contact root surface,
2. Straight working to the deep pocket,
3. More power to remove the deposit of root,
4. Insert tips too long to approach posterior area,
5. Irrigator liquid too expensive...
