8. Just like diamonds and carbides, finishing and polishing instruments come in a range of shapes that are suited for certain materials, procedures, or restoration areas. grit Mopper KW. These polishers come in a variety of shapes suitable for these materials. There are many different types of finishing and polishing instruments, and many instruments have overlapping capa- bilities, which can make it very difficult to choose. Discs can be used for the contouring of all tooth surfaces as well as bulk reduction of excess material. Nanohybrids or nanofills can also be used to replace the enamel layer in composite restorations. When used with pressure, the coarse disc makes it easy to blend the composite into the tooth surface, eliminating the white line and raised margins. Would you like email updates of new search results? The ability to achieve a good finish and polish on anterior composites is determined by two very important factorsaccess to the right materials and the artistic ability of the dentist. 2004;23(5):74-79. Polishing the surface is completed with fine and then superfine polishing discs. 1. View cart for details. Bookshelf Significant differences (p<0.05) were detected among both the resins and the finishing/polishing techniques. An official website of the United States government. A larger-grit (45-m strip) should be used for interproximal stripping of natural teeth or for gross removal of material, and smaller grits (15 m and 30 m) should be used to start interproximal polishing. Jefferies SR. Abrasive finishing and polishing in restorative dentistry: a state-of-the-art review. Bethesda, MD 20894, Web Policies To provide maximum control for the operator, composite finishing should be done under low-speed/high-torque (speed from 0 rpm to 30,000 rpms). Diamond abrasives are more expensive, last longer, have a faster working time, and provide a mirror finish. 2020 Jun 24;8(2):60. doi: 10.3390/dj8020060. A high-speed handpiece may be used to pre-contour, but using anything over 30,000 rpm during finishing and polishing is too high. One- or two-step polishers can certainly be used when polishing composite restorations quickly. Overall, the smoothest surfaces were obtained with the use the complete sequence of Sof-Lex discs. Adherence of Streptococcus mutans to uncoated and saliva-coated glass-ceramics and composites. A small amount of aluminum-oxide polishing paste is then applied to each surface and polish. So the choice of instrument material and shape will be driven by both the procedure and the dental material to be worked with. MeSH Many practitioners lose the shape of the restoration because of a lack of attention to the material application phase. Both types offer points, cups, and discs to suit all procedures. They are also excellent for contouring and finishing of posterior marginal ridge areas, and for lingual and buccal surfaces. 2020 Jul-Aug;23(4):395-401. doi: 10.4103/JCD.JCD_401_20. Ten specimens of each composite resin were randomly subjected to one of the following finishing/polishing techniques: A -- carbide burs; B -- fine/extrafine diamond burs; C -- Sof-Lex aluminum oxide discs; D -- Super-Snap aluminum oxide discs; E -- rubber polishing points + fine/extrafine polishing pastes; F -- diamond burs + rubber polishing points + fine/extrafine polishing pastes; G -- diamond burs + Sof-Lex system; H -- diamond burs + Super-Snap system. Use of a high-quality strip will remove tenacious stains and create a high polish at the interproximal without damaging the soft tissue. Disclaimer, National Library of Medicine official website and that any information you provide is encrypted Before finishing and polishing, the dentist must conceptualize the desired end result. and transmitted securely. This article outlines the importance of three different phases in the finishing and polishing process.

The coarse disc or contouring bur is used to start contouring and finishing. 95% of patients would recommend Hydration Whitening by TheraSmile. 7. An enamel-like luster rapidly appears. The fine grit helps remove the smallest imperfections while adding a nice luster to the restoration.

Then, the dentist must conceptualize the desired end result, and set up the restoration accordingly. Dent Mater J. Aluminum-oxide points should be used to create labial grooves in veneers, to finish and polish occlusal surfaces of posterior teeth, and on lingual surfaces of anterior teeth. Mosby, St. Louis, 1997,p263. The site is secure. Epub 2021 Mar 20. For the final polish, an aluminum-oxide polishing paste with felt discs and points is used. Over time, however, nanofill composites lose their luster and are less wear-resistant than microfill composites8 Microhybrids are the least polishable of the three main composite types. Silicon carbide is generally the preferred abrasive for porcelain, acrylic, and gold, as it will not cause discoloration. To achieve a beautiful, long-lasting polish, a microfill composite must be used as the final layer. If done properly, any white line or raised margin will completely disappear.

It is desirable to maintain the character and anatomy placed in the facial surface. It is important that the strip is thin and will stay intact as it is drawn through the interproximal contact areas.

The material should be extended well past the long bevel, and the dentist should not come back to the beveled margin.

We have tried to present the trade-offs to give you guidance on choosing the best instrument for the procedure. Oper Dent. Finishing and polishing anterior composite restorations is a sophisticated art form. The coarse and medium discs can be used to complete the contouring of the veneer. Used as an anterior enamel layer, microhybrids rapidly lose polish and are more susceptible to staining. MediumThe medium grit should be used to continue smoothing the restoration surface. A realistic tooth form should be developed before the pre-contouring phase begins. How do composite resins stand the test of time? Either multi-fluted carbides or fine diamonds for gross contouring can be used to begin finishing the restoration. Different types of composites call for different polishing techniques, depending on the type of restoration and the dentists ultimate goals. Now it is time to apply the correct technique during the final phases of the restoration. 5. Although this is a small diameter, the 3/8 disc can be flexed to gain access to hard-to-reach areas. Surface Geometry of Four Conventional Nanohybrid Resin-Based Composites and Four Regular Viscosity Bulk Fill Resin-Based Composites after Two-Step Polishing Procedure. SuperfineThe superfine grit further refines the surface smoothness attainable to create a highly polished restoration. This site needs JavaScript to work properly. Am J Dent. In areas that could not be reached by the aluminum oxide discs, the carbide burs and the association between rubber points and polishing pastes produced satisfactory surface smoothness for the packable and hybrid composite resins, respectively. This study examined the average surface roughness (Ra, microm) of 2 microfilled (Durafill and Perfection), 1 hybrid (Filtek Z250) and 2 packable composite resins (Surefil and Fill Magic), before (baseline) and after eight different finishing and polishing treatments. Grinding and finishing abrasives and cutting discs provide fast contouring and finishing. Excessive staining is removed in the usual fashion. 2009;22(2):102-110. Gen Dent.

The author is an advocate of the four-grit disc sequence, which is designed to gradually reduce the amount of roughness caused by initial abrasion until a smooth glossy tooth surface is achieved. Member and Fellow Effect of Polishing Systems on the Surface Roughness of Nano-Hybrid and Nano-Filling Composite Resins: A Systematic Review. If a part of this process if skipped, the tooth will often be left rough and susceptible to plaque and staining. Single-use items provide convenience, while multi-use instruments are more economical. CoarseThe coarse grit is the stiffest of all the discs. Low-speed, high-torque is preferable, because it gives the operator complete control.
