Most of the anterior custom implant abutments we create are zirconia, with a metal interface. We typically place the labial margin about 2mm subgingivally to decrease the chance for show-through or exposure. We have recently started to shade the area of zirconia below the margin a subtle pink color to improve the esthetics of the final restoration, and to decrease the prominence of the zirconia color, in the event of thin biotype or recession. We believe you will like this improvement.

ROE wants your photographs, particularly for anterior restorations, ClearMatch processing, smile design, smile imaging, stick bites, denture resets, etc. Photographs turn stone models into patients. Sadly, many offices we serve have digital cameras that output pictures that areless-than-desirable, and camera settings are the usual culprit. We’d like to help you improve your photography. This can be accomplished with an office visit, or an emailed image for evaluation. Call our lab or email a photograph to email@example.com, and we will be happy to offer suggestions to dial in your settings.

DENTSPLY has developed the Aquasil Ultra Cordless Tissue Managing Impression Material and digit power™ Dispenser as a means for dentists to precisely place subgingival material for improved crown and bridge impressions without the need for retraction cord or retraction paste. The dispenser is a pneumatic impression device that is compatible with most dental units. It connects to an air line at the dental chair and allows the dentists to simply step on the rheostat to express material while holding the impression device in a pen-grip. The small diameter intraoral tip on the impression cartridge allows placement directly into the sulcus or around a dental implant. It is designed for use with a single-step dual-viscosity impression technique. For the complete news flash, see our web site blog, linked on our home page.
Don’t be stuck without the correct tools when an implant case is in the schedule. Call Salvin Dental Specialties, a company that manufactures “Tips” (torque driver inserts) that are compatible with rival implant companies. For example, if you have a Zimmer Dental torque wrench, but an Astra implant case presents, rather than purchase the expensive Astra Driver Kit, call Salvin and order their compatible Astra Tip that fits into your Zimmer wrench. Visit www.salvin.com and click on Torque Wrenches on the lower left.

|Monolithic structure with labial veneering|
This year we began offering the TLZ-IB bridge. This 98% monolithic restoration is increasing in popularity as a premium fixed implant-supported solution for the treatment of the edentulous patient. Dentists are choosing this option for several compelling reasons: durability has the potential to exceed traditional hybrids and overdentures; labial veneering is esthetically superior to denture teeth; vertical requirement is only 10mm, and maintenance is much lower than traditional hybrids. As we mentioned in a previous newsletter, the protocol for completing TLZ-IB is very predictable - and unique. Visit our web site to download the Quick Steps Procedure.
By many reports and surveys, Zirconia is now the most popular, indirect restorative material. Despite its wide use, some dentists and laboratories still have questions regarding wear, longevity, hardness, removal, esthetics, etc. We recently consulted with Rella Christensen, PhD, Director of TRAC Research Provo, UT, on zirconia properties. TRAC Research is a 37-year-old, respected dental-materials testing company that, during the past few years, has placed an emphasis on in-vitro and in-vivo zirconia restoration studies, and will publish the three-year-findings in several months. Following our conversation, we became even more convinced that full-contour zirconia is the most viable material for posterior restoration. Monolithic zirconia has it all: high-strength, low-wear, softness, low-heat conductivity, and conservative preparation.
Dr. Christensen will be joining us in Cleveland, OH on April 11, 2014 for a complete materials update seminar. This will include the release of TRAC’s findings on zirconia and emax CAD, as well as announcements of other material options that are currently being tested.
Dr. Christensen did mention a few clinical cautions. Due to the difficulty in removal and endodontic access, she recommends following preparation and occlusal reduction parameters similar to full-cast restorations. Full zirconia should be seated using reinforced glass ionomers, and not bonded. When restorations are adjusted, it is recommended a high-shine polish be completed to ensure natural wear to the opposing teeth. And, if a crown must be removed, it should be addressed with a new, fine diamond, low-to-medium pressure, with lots of water allowing the diamond to do the work.
When asked what she would place in her own mouth, the immediate response was “absolutely full-contour zirconia, and yes I’m speaking about 1st and 2nd molars”.
