Atraumatic Extraction Kit [KAE001]

Used for the immediate and effortless extraction
of the root of the tooth with simple procedures.

1. Diversity
  • A root extraction can be done regardless of whether
    residual amount of root is large or small.
2. Safety
  • A tooth extraction without the risk of Damaging adjacent
    teeth is possible using the Rest Plate, Elevator, etc.
3. Convenience
  • A very simple and convenient tooth extraction is possible,
    as compared to the existing extraction method.
4. Reduced Procedure Time
  • The procedure time is reduced due to the simple procedure.

Composition
1. Extraction Drill
  • The Extraction Drill is composed of three types of drills (Ø1.3 / Ø1.7 / Ø2.1) that can be selected according to the case.
2. Extraction Screw
  • The Extraction Screw is fastened into the hole that was created by the Extraction Drill via the screw method, and it is stably fixed
    to the remaining tooth. It is composed of the Ø1.8 / Ø2.2 / Ø2.6 Screws that can be selected according to the Extraction Drill.
  • Ø1.8 Screw is used for vital root of which canal is not treated, after using Ø1.7 Drill.
3. Post Driver
  • After connecting the Post Driver to the Extraction Screw, turn the Torque Wrench in a clockwise direction in order to fix it to the
    hole that was created by the Extraction Drill (recommended torque : 30 N.cm or more).
4. Rest Plate
  • The Rest Plate is connected between the Extraction Screw and the Torque Head.
    It protects the part with silicone that comes into direct contact with the adjacent teeth in order to prevent teeth damage.
    It also serves as a support for the elevator and torque wrench.
5. Torque Head
  • The Torque Head is connected to the Extraction Screw that is fixed in the tooth to be extracted.
    It fixes the gap of the Rest Plate and it can be used with the Elevator.
  • If the root to be extracted has both distal and mesial adjacent teeth,
    it will be extracted with a Torque Wrench (recommended torque: 100 N.cm or less).
6. Elevator
  • The Elevator is used by connecting it with the Torque Head and extracting the root by applying force toward a distal or mesial direction.

How to Use

1. Extraction Drill

Create a hole on the tooth to be extracted using an Extraction Drill.

Caution A
  • The Extraction Drill must follow the neural root canal during drilling.
  • Drill down to at least 10mm because extraction is possible even if the drill
    and screw penetrate the dental root.
2. Extraction Screw

Connect the Extraction Screw to the Post Driver
and fix it to the hole created by rotating it clockwise (recommended torque: Min. 20 N.cm ~ Max. 25 N.cm).

Caution B
  • Drill to a depth of 10~12 mm and insert the Extraction Screw at a depth of 10 mm.
  • Fix the screw with 20~25 N.cm.
* Drilling Sequence

Root Canal Preparation

Caution C
  • Fix the screw with a torque of 20 ~ 25 N.cm. If it is not applied, use a thicker screw.
  • The low torque force causes the screw to fall out during the extraction, and the overtorque force fractures the root.
3. Rest Place

After removing the Post Driver, connect a Rest Plate to the Extraction Screw by taking into account the adjacent teeth.

4. Torque Head

Connect the Torque Head to the Extraction Screw projected above the Rest Plate by rotating it clockwise.

5. Torque Wrench

Extract the tooth by rotating the Torque Head clockwise using a Torque Wrench.

Caution D
  • Extraction using the Torque Wrench is possible in a root with mesiodistal root.
Caution E
  • If there are adjacent teeth with 2 or higher swaying degrees, upward pulling or
    downward pressing should be applied using an Elevator so that the teeth
    will not receive force during extraction.

Caution F
  • If there is an adjacent tooth projected to the mesiodistal root,
    it must be extracted using the Elevator.
