To do this, this instrument is inserted into the space previously left by the syndesmostoma (between the root cementum and the alveolar bone), and acts as a lever. Thus, the luxating elevator will allow to break all the desmodontal fibers in order to completely dislodge the tooth. The elevator will use the alveolar bone for support and not the neighbouring teeth to avoid damaging them. When the tooth is mobilised, an audible sign called "sucking sound" or "singing tooth", which the air makes as it passes between the tooth and the alveolus, means that the action of the elevator is complete. All that remains is to grasp the tooth and remove it completely from the mouth.
Seldin root elevator have the following characteristics:
- Seldin's standard root elevator are non-removable and feature a thick, rounded and fairly heavy handle that provides a solid grip for safe and efficient operations.
- The handle is followed by a long shaft and a very thin, rounded, slightly hollow tip that is angled backwards to fit the roots perfectly.
- The spoon-shaped tip has a convex outer surface that contacts the alveolar bone, and a concave inner surface that contacts the tooth, allowing for easy extraction. The Seldin root elevator will distend the ligaments surrounding the neck, allowing the tooth to be released easily.
- Very sharp tip: softer than the Bernard root elevator, these round elevator of increasing size are also sharp at the tip to act effectively, but as atraumatically as possible when dislocating the tooth or root.
