business54 IDS 2013 – 13. März 13 March Durch speziell abgestimmte Mikrofüller bieten die neuen licht- härtendenPastenopakerdesUniver- sal Opaque Systems von SHOFU exzellente Deckeigenschaften und einen herausragenden Verbund zu allen gängigen Dentallegierungen. Nach Angaben des Herstellers sind die Pasten dank verbesserter thixo- tropen Eigenschaf- ten jetzt wesentlich softer und fließfähi- ger und lassen sich äußerst leicht und schnell auftragen. Das gebrauchs- fertige Opaker-Kon- zept, bestehend aus einem Pre-Opaque und 31 Einzelmas- sen, kann als Basis für die Anfertigung aller Farben der Ce- ramage und Solidex Komposit-Systeme sowie anderer Ver- blendkomposite an- gewendet werden, so die Firma. Owing to its specially adjusted mi- cro fillers, the new light curing paste opaquesoftheUniversalOpaqueSys- tem from SHOFU offer excellent masking properties and adhesion to all common dental alloys. According to the company, enhanced thixotrope properties make the pastes much softerandmoreflowable. Inaddition, the can be applied more easily and quickly. Thereadytouseopaqueconceptof one Pre-Opaque and 31 individual compounds can be used as the basis forallcoloursoftheCeramageandthe Solidex systems as well as other ve- neering composites, the company said. SHOFU DENTAL www.shofu.de Hall 4.1 Booth A040 In an effort to increase the indica- tionsforBruxZirSolidZirconiacrowns, theR&DdepartmentatGlidewellLabo- ratories is constantly working towards increasing the translucency of this monolithiczirconiamaterial.Whilethe dental laboratory is not yet to the point of being able to do veneers, anterior BruxZir crowns are starting to come intotheirown.InPart2ofthisphotoes- say provided by Dr Michael C. DiTolla, NewportBeach,Calif,USA,theReverse Preparation Technique is used to prep tooth #8 (a natural, endodontically treatedtooth)and#9(afailingPFM)for BruxZir crowns. This case is also available as a video demonstration on Glidewell’s website. The 801-021 round diamond bur from the Reverse Preparation Set is used to cut a half-circle into the gingi- val third of the tooth (Fig. 1), which is the formation for the perfect margin. Another depth cut is made to ensure adequateincisalreduction(Fig.2)and aMADC-020burisusedtoplace2mm depth cuts in the incisal edge of #8, which will give the technician a good opportunity to build an aesthetic, strongincisaledge.Thepreparationse- quence is then completed by using the MADC-015, 856-025 and Alpen 379- 023 burs. The next step of the Reverse Prepa- ration Technique is to place the #2E Ultrapaktopcord(Fig.3).Packingthis second cord can be difficult; you can’t floss it into place interproximally like you can with the first cord because do- ing so would disrupt the bottom cord, whichwewanttostayfirmlyplantedat the base of the sulcus. Once the top cord is in place, you get one last look at your margin. One cannot be entirely happy with the result because the shapeofthemargindoesnotmatchthe contour of the gingiva. The margin was prepped with a su- per coarse 856-025 bur, which left lit- tlechips,soafinegrit856-025burwas used to get rid of that choppiness (Fig.4).AfterplacingtwoROEKOCom- precap Anatomic compression caps for 8–10 minutes, the top cord can be removed and the impressions can be taken. After five days, the patient re- turned for temp removal and final BruxZir crown try-in. The BruxZir crowns fit well, so it was time to start the cementation procedure. Zirconia crownsaresusceptibletosalivarycon- tamination when they are tried in the mouth. Fortunately, Ivoclean was re- leasedearlierthisyear,specificallyfor the purpose of cleaning out restora- tions prior to bonding or cementation. A couple drops were placed in both of the crowns that will stay in place for 20 seconds before being rinsed away (Fig. 5). Ceramir which contains the same phosphate groups that bond to zirconia, was then used to cement the BruxZir crowns (Fig. 6). It is not suggested that dentists switch to this material for all of their anterior crowns. Unless patients pres- ent with other broken restorations or show higher-than-average wear, clini- cians may be better off sticking with IPS e.max for this type of situation.
