3m Espe Sof-Lex Spiral Wheels-Refills
Sof-Lex Spiral Finishing and Polishing Wheels are a unique two-step, single use finishing and polishing system. The flexible shape of the wheels allows them to adjust to the contours of a tooth surface – even if the tooth surface is irregular, concave or convex in shape. This means you can now polish anterior and posterior restorations with one versatile tool... So why use points, cups, discs and brushes when one shape will do?
Sof-Lex Spiral Wheels…
- Adapt to all tooth surfaces, work from any angle
- Are effective at reaching anterior and posterior restorations
- Quickly achieve a life-like luster
- Resin-modified glass ionomers
- Bisacrylic temporary materials
- Resin nano ceramic – Lava Ultimate CAD/CAM Restorative
- Precious and semi-precious metal
Sof-Lex™ Spiral Finishing and Polishing Wheels are the versatile tools after the initial contouring! Their innovative new product design makes dental finishing and polishing easy and convenient.
- Their unique, flexible shape easily adapts to irregular, convex and concave tooth surfaces.
- Anterior and posterior restorations can be finished and polished with one tool for each step, no need to switch between points, cups discs and brushes.
- All parts of the spiral wheel can be used: side, top, bottom and edge. Therefore, the spiral wheels are effective from any angle.
- The fine finishing wheel (beige) smoothes and removes scratches in restorations that develop during contouring, and prepares the surface for high gloss polishing.
- The superfine polishing wheel (white) creates a very smooth, high-gloss polish.
- Sof-Lex Spiral Finishing and Polishing Wheels are for single use and work without paste and water cooling.
Convincing Performance- Performance for finishing and polishing systems is typically evaluated by measuring surface gloss, surface roughness and heat generation.
Gloss Attainment- Surface gloss or reflectance indicates how polished or shiny the surface can become after treatment. A high gloss attainment indicates a shiny, more reflective surface.The study shows Sof-Lex Spiral Finishing and Polishing Wheels produce a smooth gloss surface better than or equal to the industry’s leading products.
Surface Roughness- Surface roughness actually measures how rough or smooth the surface is before and after treatment. Sof-Lex Spiral Finishing and Polishing Wheels produce a smoother or similar surface roughness compared to the industry-leading products.
- The surface roughness can be quantified using surface profilometers. A profilometer drags a stylus over the surface. In this case, Ra (average surface roughness expressed in units of height) is the parameter reported. The lower the Ra (average surface roughness), the smoother the surface.
- SEMs can be used to observe the actual surface roughness.
- Sof-Lex Spiral Finishing and Polishing Wheels produce a smooth surface better than or equal to other leading products. The left picture shows the unpolished material while the material on the right has been polished using Sof-Lex Spiral Finishing and Polishing Wheels.
Heat Generation- Many finishing and polishing devices generate heat during use. Manufacturers may recommend water cooling or intermittent pressure to ensure excessive heat does not build up.
Sof-Lex Spiral Finishing and Polishing Wheels generate less heat on the surface compared to a leading rubberised system- The surface temperature was measured before and during treatment.
Gross Reduction- The purpose is to remove excess restorative material (including overhangs), to remove air-inhibited layer, and shape anatomy. The tools that are typically used for this process deliver the most aggressive abrasive (e.g., coarse grit) action in this procedure to remove the excess material quickly. The graph on the right depicts the most popular tools for Gross Reduction. Strips are also used for proximal areas.
Final Contour- The purpose of this step is to refine contours (size, shape, grooves, etc.) and margins (generating a smooth transition from tooth to restoration), re-establish contact with adjacent teeth to a normal and functional form, and reduce surface roughness. At the end of this step, the restoration should have its desired form and a smooth, clean surface. The most popular tools used for Final Contour are depicted in the graph on the right. Strips are also used for proximal areas. These tools are not as aggressive as those used for Gross Reduction (e.g., medium grit) because only small amounts of material are being removed from the restoration.
Finish Smooth surface (scratch removal)- This step reduces the scratch depth and/or removes lighter scratches produced during the Gross Reduction and Final Contour steps by the more aggressive tools. This step should leave the surface smoother and sometimes is considered a pre-polish step. The tools used for this step, as depicted in the graph on the right, are less aggressive than the previous step (e.g., a fine grit). Strips are also used for proximal areas. The fine Sof-Lex Spiral Finishing Wheel is designed to remove scratches and smooth the surface.
High Gloss Polish- The objective of this step is to further smooth the surface to produce a high gloss shine on the restoration. The tools used for this step, as depicted in the graph on the right, are the least aggressive (e.g., super or ultra fine grits). Strips are also used for proximal areas. The superfine Sof-Lex Spiral Polishing Wheel produces a high gloss polish.
HOW TO USE ?
- Sof-Lex Spiral Finishing and Polishing Wheels are designed to fit perfectly into the Sof-Lex System.
- They use the same mandrel as the discs – and because the discs and wheels feature easy, pop-on mounting, you can move efficiently through your contouring, finishing and polishing procedure.
- Sof-Lex discs, strips and spiral wheels are colour-coded from dark (coarse) to light (superfine) for an easily followed step-by-step process.
