Occlusal Sweeps

Occlusal Sweeps (Hydraulic VPS Spreader)

When applying impression material to the prepared and adjacent teeth, it is of primary importance to ensure that all areas, including undercuts, are effectively covered. If the impression material does not closely adapt to all occlusal and proximal dental surfaces, bubbles and gaps will cause inaccuracies that compromise the accurate fit of the crown (or bridge). Even a small discrepancy can result in the practitioner spending uncomfortable sessions adjusting the crown (or bridge) to fit the patient’s prepared teeth. Danville Materials has introduced the Occlusal Sweeps positioning tube to accurately place impression materials where required. It fits onto the tip of automix impression material dispenser tips and helps to force the impression material into nooks and crannies around the preparation. The Occlusal Sweeps is split into 3 leaves: buccal, lingual, and trailing occlusal. This splays the tip as it passes over the teeth, spreading the impression material more effectively. First seal the distal of the tray with DAMit! membrane (Danville Materials) to prevent the material from flowing out inadvertently (also prevents gagging). Then, load the tray with regular/heavy-body impression material. Finally, adapt the light-body impression material to the preparation and the adjacent teeth with the Occlusal Sweeps. It will push moisture and air ahead of the impression material, allowing no bubbles to form. Once the light-body impression material has been spread over the prepared area by the Occlusal Sweeps, the filled impression tray is inserted over the light-body material and is held in place until the impression material has polymerized. The combination of truly hydrophilic impression materials, a good tray technique, and the Occlusal Sweeps make impression-taking a simple and predictable procedure.  For more information, visit danvillematerials.com.
