Finishing and Polishing of Restorative Materials

The well-finished and polished restorations are not only esthetically pleasing but are also conducive to the oral environment. Finishing and polishing of both the occlusal and proximal areas is important, since the proper marginal adaptability of the restoration, by and large, saves an individual from periodontal problems thereby achieving better clinical success of the treatment.Finishing and polishing techniques are important in preparing clinically successful restorations. Untoward surface irregularities resulting from poor finishing and polishing may lead to the accumulation of plaque, recurrent decay, chronic gingival inflammation, and staining by chromagenic foods and beverages- all of which shorten the efficacy and durability of even the most meticulously placed restoration. Hence, it is important for a dental clinician to have appropriate knowledge regarding finishing and polishing procedures for restorations.The process of abrasion is affected by properties of the abrasive and the material being abraded. Finishing and polishing begin with coarse abrasives and end with fine abrasives.Clinically it is easier to control the rate of abrasion by speed rather than the pressure.
