The Vac-Wedge ™ is indicated for interproximal placement between teeth to facilitate evacuation of fluids during direct placement of restorative materials.
Wedge body: Polyethylene
To avoid inadvertent swallowing or aspiration of the wedge, always grasp the plastic wedge body with cotton pliers. Do not tug on the tubing as this will cause the wedge to disconnect.
The Vac-Wedge™ is non-sterile.
The Vac-Wedge™ is for single use only. Discard after use to prevent cross-contamination. Any use of this product inconsistent with the instructions is at the discretion and sole responsibility of the practitioner.
DO NOT sterilize as this will cause permanent deformation of the wedge making it inoperable.
- Connect silicone tubing to the wedge body at a 45-degree angle. Ensure the silicone tubing is completely seated over the barb connector. Caution: incomplete seating will result in a weak connection, leading to a potential hazard for aspiration or ingestion of the wedge body.
- Select appropriate size wedge. If unable to completely insert into interproximal space, modify wedge with dental bur using light pressure. A white stone is ideal. If modification is minor, cotton pliers can be used to burnish the wedge to a thinner configuration.
- Fully seat vac wedge. The wedge suction ports on side walls must be inside the line angles for proper function.
- While the doctor performs steps 2 and 3, the dental assistant must expand the soft saliva ejector tip by inserting a cotton plier into the center ring of the saliva ejector, breaking open the center ring.
- Pull the newly opened saliva ejector tip apart and insert the tubing. Manually compress the ejector tip until some resistance is felt when tugging on the tubing. Lack of tug back may cause the wedge to fall inside the saliva ejector tip. Adjust the length of the tubing by sliding tubing in or out of the saliva ejector tip.
- A second wedge may be added if required.
- Bend saliva ejector tip and secure by placing inside the floor of the mouth. The saliva ejector tip remains fully functional.
- Activate suction. If wedge is not suctioning, check for kinked tubing inside saliva ejector tip or excessive bending of the saliva ejector tip. Rinse and dry preparation. Confirm dry field. Finish restoration.
- Three suction zones are active in the mandible when the wedge is lingually placed with a full tofflemire band: 1. The floor of the mouth with the saliva ejector tip; 2. The zone lingual to the matrix band to assist in fluids pooling from the submandibular salivary glands; 3. The interproximal space between two teeth.
- Always grasp the plastic wedge body with cotton pliers when removing wedge from interproximal spaces. DO NOT tug on the tubing as this will cause the wedge body to disconnect.
