Clinical Success Rates of Ceramic vs PFM Restorations

Description:
Dr. Rella Christensen, a researcher at Clinical Research Associates (CRA) which publish Clinician’s Report, discusses recent findings of in depth studies comparing Zirconia to PFM to Alumina frameworks in restorative dentistry. Both CAD/CAM and Pressed ceramics are studied relative to their long-term clinical durability when compared to PFM restorations.

What is the current status of these bridges? Do you have a new update on all zirconia bridges that would help us in our decision making?

keeping the anatomy simple for zirconia veneered ceramic is a very clever and gud tip.i appreciate

Good work. Please keep us up to date so that we can see if press ceramics give good reults after 5 and 10 years incorporated.

I would like to hear more from CRA, Rella on all of their research.

Nallesh,
you are correct in that removing Zirconia crowns cemented to etched dentin substrate is extremely difficult and time consuming - - and they seldom if ever don't break during removal as you have to use a high speed and effectively have to grind them off in small pieces
- - - you do have a much better chance with pfm's but again it depends on the cementation

The importance of supporting porcelain on zirconia frameworks cannot be overstated. I'm glad she brought this point to attention as many technicians are starting to hear about his more and more.

Good information... I would love to hear some studies comparing single unit performances of the various ceramic options

[quote=Nailesh Gandhi]I have listened to presentation by Dr. Rella Christensen, a researcher at Clinical Research Associates on topic on which is better - PFM ,Zirconia and Alumina.Lots of doubts have been cleared by her superb clear report.Such reports when presented is similar style gives instant benefits for clinicians.Please do continues with similar clinical presentations.I have to make one observation as regards to PFM and Zirconia.It is easier to remove PFM than Zirconia crowns as they may break during removal.I have not experienced such incidence so far but just an apprehension.If some one with more experience can enlighten us it will be great![/quote]

Somehow I missed your question, Nailesh, and want to give you an accurate answer so please let me have a bit more information: First, do you mean at try-in or after final cementation? and second, if final cementation, what are you cementing your crowns with (both PFM and Zirconia)? And third, how are you trying to remove your crowns?

The Clinical Relevance of Digital Dentistry & 3D Technologies
The implementation of modern digital technologies into the clinical practice requires a step by step process. Photography, optical scanning and stitching of CBCT images allow for Digitally rendered smile designs that then lead to guided procedures and 3D printing of mockups, provisionals and surgical guides. This presentation will highlight the role of digital dentistry in a modern dental office and the steps required to prepare oneself for this evolution.

Digital Workflow for Anterior Implant Aesthetics Premium Member Content

Digital Workflow for Anterior Implant Aesthetics
We have seen excellent results in the aesthetic zone when immediate implant placement techniques have been used. A review of the current literature reveals and confirms the re-education of mid-buccal facial recession is best when an immediate provisional is used. If we can digitize this information and create a crown-root form matrix, we can allow tissue to maintain the exact 3D position of the crown and root of the tooth that is to be replaced. A technique using "dicom" files and "STL" files of the original tooth-root will be demonstrated. This will allow ideal healing of the surrounding hard and soft tissues in for any implants restoration.

A Biometric Approach to Predictable Treatment of Clinical Crown Discrepancies
Dental professionals have long been guided by mathematical principles when interpreting aesthetic and tooth proportions for their patients. While many acknowledge that such principles are merely launch points for a smile design or reconstructive procedure, their existence appears to indicate practitioners’ desire for predictable, objective, and reproducible means of achieving success in aesthetic dentistry. This article introduces innovative aesthetic measurement gauges as a means of objectively quantifying tooth size discrepancies and enabling the clinician to perform aesthetic restorative dentistry with success and predictability.

Surgical Crown Lengthening in a Population With Human Immunodeficiency Virus: A Retrospective Analysis

Surgical Crown Lengthening in a Population With Human Immunodeficiency Virus: A Retrospective Analysis
This report investigates the outcome of CLS procedures performed at an urban dental school in a population of individuals with HIV. Specifically, this retrospective clinical analysis evaluates the healing response after crown lengthening surgery (CLS). Of the 21 patients with HIV examined after CLS, none had postoperative complications, such as delayed healing, infection, or prolonged bleeding. Variations in viral load, CD4 cell count, smoking, platelets, and neutrophils did not impact surgical healing. In addition, variations in medication regimens (highly active anti-retroviral therapy; on pro-tease inhibitors; no medications had an impact. The results of this retrospective analysis show the absence of postoperative complications after CLS in this population with HIV. Additional investigation into this area will help health care practitioners increase the range of surgical services provided to this group of patients.

This has been possible not only because of improved techniques and materials, but also because of the understanding that tooth preparation, regardless of how conservative it may be, is an irreversible procedure
