This year we attended several meetings in Chicago including The American Equilibration Society, American Prosthodontic Society, The American Academy of Fixed Prosthodontics, and The American Academy of Restorative Dentistry. Several themes were repeated which I have highlighted here along with a couple of exciting new products.
Obstructive Sleep Apnea was a topic of significant discussion from many speakers this year. It appears to play a much more significant role in dentistry than we ever realized, with some now reporting a connection between OSA and bite related issues. The team of Robbins and Rouse in Texas has emerged as leaders in the field of Sleep Medicine in Dentistry. We are already working on having Dr. Jeff Rouse here next year to update all our customers on the importance of the condition and proper protocol for diagnosis and treatment of OSA. Bay View Dental Lab plans to host the program at the Mid-Atlantic Center in the fall of 2013 (date to be announced).
Materials were discussed by many, and lithium disilicate (IPS e.max) continues to be recognized as a leading material for restorative dentistry. More and more studies confirmed what we have been experiencing – it is a very robust material. Some studies were reporting no drop-off in strength at 1.2mm of occlusal clearance. While we still recommend full contour zirconia on second molars when occlusal clearance is less than 1.5mm, we continue to see e.max as our first choice restoration for posteriors overall. I am continuing to work with these restorations personally every day and can attest first hand to the strength, impeccable fit, excellent esthetics, and all around versatility of e.max as a restorative material. Coinciding with the rising popularity of e.max was the release of a new material from 3M called RelyX Ultimate Adhesive Resin Cement. RelyX Ultimate has reduced the number of components while maximizing the bond strength. It is a significant improvement in adhesive dentistry.
The trend in implant dentistry continues away from cemented restorations, and back toward screw-retained restorations. Research shows that some of the reason for this edging away from cemented implant restorations is irretrievability when something goes wrong and the number one cause of implant failure – cement in the sulcus. One option for avoiding these situations is to go with screw-retained crowns. Of course, these restorations require a much more precise placement of the implant and tend to be quite a bit more costly. Another highly successful option is to simply use a patient-specific CAD/CAM abutment with proper contouring and support of the tissue around the implant abutment. The patient-specific CAD/CAM abutment has been our recommendation for several years now. We’ve found that the Atlantis Gold Hue option, with a full-contour e.max crown, provides exceptional results. The total bill for this restoration, including implant model, parts, custom abutment, and crown is still just $595.00. We recommend using Ceramir, a new generation of cements created for the specific demands of implant dentistry.
These specific topics are among many that will be discussed at Dr. Bob Faulkner’s course “Current Concepts in Implant Dentistry: Diagnosis and Treatment Planning” here at Bay View Dental Laboratory on November 8-10, 2012. Contact Kim at 757-222-9843 for more information or to register.
