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.

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.

Ron Duffin - (12/11/2009 11:38 AM)

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?

Surgical Veneer Grafting - Compensation for Natural Labial Plate Remodeling After Immediate Implant Placement

Surgical Veneer Grafting - Compensation for Natural Labial Plate Remodeling After Immediate Implant Placement
Contemporary implant therapy aims to provide highly esthetic and predictable treatment outcomes while decreasing treatment duration and complexity. The clinician must therefore be cognizant of circumstances with a predisposition toward esthetic outcomes and treatment plan accordingly. Preservation of the surrounding hard and soft tissues associated with an immediate postextraction socket implant to replace a nonrestorable tooth in the esthetic zone is one of the greatest challenges facing the dental team. A case report of a hopeless maxillary left central incisor in a patient with a thin periodontal phenotype illustrates this new surgical and prosthetic approach. Clinical, radiological, and esthetic parameters were recorded to evaluate primary treatment outcomes.

The "Hybrid Abutment": A New Design for Implant Cemented Restorations in the Esthetic Zones

The "Hybrid Abutment": A New Design for Implant Cemented Restorations in the Esthetic Zones
Cemented implant restorations are widely used by many dentists. The traditional abutment design resembles a natural tooth prepared for a crown with a similar taper and a chamfer finish line. A frequent complication associated with implant restorations in the esthetic zones is the recession of buccal gingiva over time. Abutment morphology, among several other prosthetic factors, may play an important role in the stability of gingival margin in esthetically sensitive areas, but this has never been thoroughly analyzed. With many considerations in mind and recent techniques released, this article proposes the "hybrid abutment: design (HAD), a new design that includes a combination of the two types of features - a feather edge on the buccal side, and a chamfer finish line on the lingual side. This article also presents a rationale for the use of different abutment designs for different situations.
