It is fair to say the economic landscape is changing both nationally and globally; changes which are essentially the advent of progress, if you will. This progress is taking place ultimately to maximize efficiencies and lower production costs, with the pursuit of providing better value and higher quality, in this advancing economy.
With respect to maximizing efficiencies, we as dental technicians, dental laboratories and dental manufacturers continue to consider new materials, plus the processes by which the materials are handled or "finished". The obvious progress with restorative materials has been with the demand, economics, science and esthetics of monolithic restorative choices. These materials are primarily designed with CAD/CAM in mind. Why CAD/CAM? The evidence shows that it eliminates many or most of the laborious, or non-productive, steps to producing a restoration. That being said, the milled outcome still requires proper finishing in order to be a saleable, final restoration. This is where efficiencies are also important. The parallel advancement of finishing instruments, like the ones offered by Wagner Rotary, provides efficiencies for laboratory finishing procedures.
Looking at this full mouth lithium disilicate case for example (Fig.1,2), it’s important to consider efficiencies with respect to finishing. For this type of case it is very important to utilize precision instruments, which ultimately make our job as dental technicians predictable. For this, Wagner has developed a variety of finishing instruments, including: hand piece diamonds, diamond infused rubber based abrasives, and diamond infused stones which avert the heating of the restorative material. My particular preference, however, are their “Diacool”, "Berry" and Hand Piece Diamonds.
Diacool diamondinfused stones are available in both medium and coarse grit varieties and simply work well. They contour with ease, precision, minimal vibration, and do so aggressively, whilst adding very little heat. This is especially important, as the restoration can easily fracture when too much heat is generated. Especially when the luxury of time is minimal. One trick I discovered is that the Diacool can contour even more aggressively when you slightly wet the restoration as you contour, and without additional pressure. (Fig. 3)
The RedBerryis surprisingly vigorous yet gentle, when finishing harder restorative all ceramics. In addition, it requires only very subtle pressure to achieve this (Fig. 4). The BlueBerryis less aggressive and is also ideal for finishing margins on zirconia and the lithium class of materials. For the polishing stage of zirconia and the lithium class of materials, the GoldenBerry works superbly. It high shine polishes predictably and with very little heat. (Fig 5, 6).
In summary, at Aurum Ceramic Dental Labs, we have found that the various Wagner instruments discussed, provide efficiency with respect to saving time, maintaining precision and provide predictability in finishing – three key factors necessary for comprehensive case finishing.
