Proper tooth preparation and bonding are important in the process of composite restorations, but what can truly make or break them is the finishing and polishing step. In order to ensure longevity as well as achieve optimal aesthetics, proper tools must be implemented. 2.731 BR Coarse Polishing Discs are incredibly flexible which leads to enhanced adaptation (since they are more likely to conform to irregular surfaces of teeth and restorations). This quality also allows for improved access, seeing as flexible discs are more easily maneuvered into tight spaces and around restorations.
It is equally as important to consider the diameter of the disc as it can significantly impact the quality as well as the efficiency of the tooth polishing. The larger discs (12,7 mm) are best utilised for the initial reduction as they are less likely to dig into the tooth and can run with the grit on either the front or the back of the tooth. While the smaller discs (9,5 mm) are better suited for refining and smoothing the restoration since they allow for more control.
These discs will provide the most efficiency if used in a proper polishing protocol:
1) It is important to start with the facial plane for anterior polishing and not move on until it is done correctly as this step is crucial for directing the tooth to its desired shape.
2) Next, the incisal edge must be worked on – this is best done when the patient is sitting up and looking straight at you. It is important to note that removing too much, and too quickly from the incisal corners can ruin the look of the tooth. Hence, discs which allow for greater control (such as the 2.731 BR 9,5 mm diameter discs) are recommended during this step.
3) Polishing proximal surfaces with polishing strips is the next step. This can be helped with firm wedging which prevents losing the contact point.
4) The palatal surface must be worked on next. This step can be done by using a rugby ball or a torpedo.
5) Checking line angles would follow the work on the palatal surfaces. At this stage, you would use the side of a propelling pencil to mark the line angles to match the ones on the adjacent tooth. Once marked, the angles can be effectively pushed out towards the edge of the tooth or wrapped from the more distal side to be brought in the other way. Regardless of the goal, this contouring can be done with the polishing discs. Once rechecking of line angles is completed, the secondary anatomy can be worked on, after which softening the grooves entails the final polishing step.
If you’re looking for flexibility, durability, ease of use as well as guaranteed patient comfort – the 2.731 BR coarse discs for gross reductions are what will provide you with all of the above. They are available in packs containing 50 pieces each and are proven to provide greater stability than the 2.731 discs. In essence, they are precisely the tools which will transform your restorations from great to flawless, so make sure to give them a try.
