AD Glidewell Laboratories continues to test what the dental laboratory can do with BruxZir Solid Zirconia crowns & bridges as it works to improve the aes- theticnatureofthiszirconiamaterial.As BruxZir crowns now account for 15 per centoftheanteriorcrownsfabricatedat thelab,thelab’sR&Ddepartmentiscom- mitted to working to increase the mater- ial’s ability to be predictably prescribed inanteriorsituations,thecompanysaid. This first part of a photo essay provided byDrMichaelC.DiTolla,NewportBeach, Calif, USA, illustrates a recent case where a patient’s tooth #8 and #9 were prepped for BruxZir crowns. The patient presented with a PFM crown on #9 that he wanted replaced and #8 had a fractured incisal edge with a failing composite and recurrent decay (Fig. 1). It was decided to place BruxZir crowns on #8 and #9, taking advantage of this high-strength, ce- mentable all-ceramic material while avoiding possible metal margins. Before moving on, the shade was taken to keep the teeth from dehydrat- ingandappearinghigherinvaluethan theyactuallyare.TheVITAEasyshade Compact was used to determine the shades of the adjacent teeth (Fig. 2). The tip of the device was tried to posi- tion in the middle third of the tooth, avoiding the increased chroma in the gingival third and the increased translucency in the incisal third. Then the PFG gel was place, an im- portant first step in giving a pain-free injection (Fig. 3). Placing the gel with an Ultradent syringe makes it easier to “sneak” some of the anaesthetic intothesulcus,sothatthepatientdoes not feel the insertion of the needle through the attachment. After 60 sec- onds, the PFG gel was washed from #8 and #9 for the purpose of starting the injection. The STA Single Tooth Anesthesia System device (Milestone Scientific) allows to predictably get pulpal anes- thesia with a pain-free PDL injection (Fig. 4). An 30 gauge extra short nee- dle was slid into the sulcus without going through the attachment. A few drops of Septocaine were continu- ously given into the sulcus prior to going through the attachment until the needle tip reached the crest of the bone. After removing the existing PFM crown using the Razor Carbide bur and a Christensen Crown Remover, the prepping of #8 began. Because this tooth has not yet been prepared, it was possible to take advantage of the Reverse Preparation Technique. The mesial contact was already broken from when the adjacent crown was re- moved,sothedistalcontactwasbroken witha#55bur(Fig.5),asthistechnique requires the first retraction cord to be placed immediately. The first cord used is an Ultrapak cord#00whichisaplaincordthathas not been soaked in any medicaments. It was flossed into place on the mesial and distal (Fig. 6). With the two inter- proximal portions of the cord locked into place, the facial segment was packed subgingivally. This bottom cord provides about 0.5 mm of vertical re- traction of the tissue, which will allow toprepthegingivalmarginrightatthe free margin of the gingiva. Continued in tomorrow’s paper.
