In collaboration with the dental techni-cian Jan-Holger Bellmann, we have com-piled a handy little instrument set con-taining ail the instruments requiredto work on crown copings and bridgeframeworks made of high-performanceceramics, such as zirconium oxide andaluminium oxide.The coarser grinding instruments con-tained in the set are suitable for elimi-nating stumps, whereas those with anextra long, slim neck are particularlysuited for adjusting the fit - even in thecase of long crown copings and bridgeframeworks, like for example in theanterior area.
The set is completed by grinding tools with long working parts and finer grits which are particularly recommended for finishing surfaces and for carrying out interdental corrections, if necessary.
Helpful hint by Jan-Holger Bellmann:
Generally spoken, grinding in the inter-proximal area is not recommended.
If this cannot be avoided, make sure to use the finest grinding tools possible, in order to keep the notch effect caused by machining to a minimum.
