Spider K1 - K2 Placement

If a Spider Screw is to be inserted in an edentulous area where there is bone availability, references from a ppanoramic radiograph can be sufficient.

1. In areas close to delicate anatomical structures, such as interadicular spaces, a long cone radiograph is recommended.
2. A surgical splint can be made with orthodontic wire, fixing it to the teeth with acrylic or thermoplastic resin. The orthodontic wire is inserted in the acrylic resin and is appropriately bent so that its tip corresponds to the point of insertion of the Spider Screw. 3
3. Use a periapical radiograph (by using the long-cone parallel technique) to verify the correct placement of the orthodontic wire.
4. The insertion site can be marked with a pressure point or methylene blue dot on the soft tissue. In mobile mucosa it is recommended to leave the surgical guide in place during the drilling phase and/or the screw insertion.
5. After site disinfection (chlorhexidine) insert the Spider K1 or K2 using the manual pick-up driver DSX-1690-S+DSP-5052-S. It is also possible to use the contra-angle pick-up driver DPQ-2820 at low speed (25/30 rpm). In order to avoid excessive torque stress during insertion, (which could cause bone compression and consequent recession or cause the screw to break) it is recommended to use a technique of alternating between screwing and unscrewing to gradually ease the screw into position. Final placement is achieved by using the handle driver DSQ- 2824 to complete the insertion as this provides the most controlled tac- tile method.
6. In the case of very compact bone use a spiral drill (FSC-1108 for K1 or FSC-1309 for K2) to make a pilot hole which makes screw insertion easy to perform.
