When it comes to chairside adjusting or in lab final adjustments, every case is treated differently, as each restoration is in fact different in size, shape, and what and how much material needs to be removed / adjusted. There is also personal preference for what instruments work best. Our guide should be helpful in determining when to use each instrument.
When A Greater Amount Of Restorative Material Needs To Be Removed
When a greater amount of zirconia or lithium disilicate needs to be removed from the restoration, it is recommended that a Diacool™ is utilized first. Diacools will safely and effortlessly remove material. If the restoration is wetted slightly, the Diacool™ will be slightly more aggressive. Diacools, like our other instruments, will stay cool and will not introduce micro fractures into the restoration. Diacools are for lab use only.
After Using A Diacool™ OR When A Smaller Amount Of Restorative Material Needs To Be Removed
After a Diacool™ is utilized or if only a minor amount of material needs to be removed, the “Berry” instruments are recommended. The Berrys are available for both lab use and chair side use. Berry instruments designed for lab use begin with the prefix “B.” Berry instruments designed for chairside use begin with the prefix “D.” Lab instruments marked with a “B,” must never be used intraorally. The Berry instruments are comprised of 4 different grits. Each Berry instrument is available for both lab use “B” Prefix and “D” chairside use. Instruments marked with a “B” prefix may not be used intraorally, and instruments with a “D” prefix cannot be used in the lab environment.
UltraBerry™ Coarse Plus RedBerry® Coarse BlueBerry ®Medium GoldenBerry® Fine / Super High Shine
Each of these instruments is industry unique. Each will reduce the restorative material as needed, but they also leave a smooth pre polish finish. This is like accomplishing 2 steps in 1. This smoother surface finish is particularly helpful in the margin areas where at times it can be difficult to control placement of the stains. By eliminating the scratches that other instruments leave, the capillary effect is eliminated, thereby keeping the stain in the area it was applied to.
Personal Preference Sequence For Berrys
Ceramists and dentists have their own preferred method for contouring, shaping and making final adjustments. There is really no correct method to follow, only our basic guidelines. Ceramists and dentists should feel free to use the instruments according to their own personal preferences. However, as a general guide, here are some basic suggestions.
Handpiece Instruments— In The Lab
We suggest using a Diacool®, (when a greater amount of material needs to be removed) followed by an UltraBerry™, RedBerry®, BlueBerry® and GoldenBerry®.
Please note that most ceramists prefer the RedBerry® for contouring zirconia and the BlueBerry® for contouring lithium disilicate.
