All you need is Kerr Finishing and Polishing Restorative Procedure Felt wheels are another one-step polishing system, with abrasive diamond particles attached to a felt matrix with the help of wax. Because of the soft matrix, felt wheels can be used on various types of composite surfaces. Due to its nature, felt wheels must be discarded after a single use. The polishing results depend strongly on the kind of pre-treatment [Jung et al., 1997; Jung et al., 2003; Scheibe et al., 2009]. Finally, gels are an alternative for polishing composites. Their application in a single or few steps is possible on all types of surfaces. Polishing gels are used on discs, plastic tips or brushes. A diamond based polishing paste achieved favourable results on a hybrid composite [Jung, 2002]. Polishing pastes based on diamond particles achieved lower roughness compared to aluminium-oxide gels [Kaplan et al., 1996]. The use of gels as a final polishing step is recommended [Turssi et al., 2000; Radlanski and Best, 2007]. For rotary instruments there is only limited access to proximal surfaces. This special situation requires the use of manual finishing and polishing strips, although their polishing efficiency seems to be limited [Whitehead et al., 1990]. Alternatively diamond-coated oscillating finishing files may be used in cases with greater amounts of excess composite material in the proximal-cervical area of composite restorations. Oscillating diamond files caused rough areas after application to cervical margins of composite-inlays. A subsequent use of polishing paste on plastic files achieved a reduction of remaining surface roughness [Small et al., 1992]. The choice of an appropriate system for finishing and polishing of composite restorations depends on a several factors; there is no universal system for all clinical indications. The accessibility and morphology (convex or structured) of surfaces and the need and extent for initial finishing is of great importance. Finally the choice of a certain polishing system should be made with respect to texture and roughness of the surfaces after initial finishing. The success of one-step polishing systems generally strongly depends on the surface condition and its remaining roughness after finishing. Polishing systems with two or more working steps are less sensitive to the kind of pre-treatment. All references are available upon request. 33
