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?

Merging Orthodontics & Esthetic Dentistry for the Anterior Zone. A Complete Clinical & Laboratory Perspective - Part 2 of 2
Anterior zone represents a clinical challenge in dentofacial esthetics. This presentation is unique since we will illustrate multidisciplinary treatment for the anterior zone from A to Z. Through the perspective of a Master Dental Ceramist & Restorative Dentist combined with the input of the Orthodontist we will illustrate with clinical cases the management of anterior esthetic challenges. Skeletal & dental problems are treated through orthodontics & orthognatic surgery prior to periodontal plastic surgery & finally high quality restorative dentistry gives the final touch to our cases. Extensive details of the ceramic laboratory work will be explained & illustrated for preserving as much as possible tooth structure. The complete management of anterior veneers & metal free crowns will be explained in detail. Color & shapes are an integral part of this webinar.

CAD/CAM Solutions for Minimally Invasive All-Ceramic Rehabilitation of Extended Erosive Lesions
Dental erosion is a global health problem that can lead to significant functional and esthetic impairments of the affected patients. Treatment of sever cases with augmented loss of the vertical dimension of occlusion (VDO) represents a challenge for both the dental team and the patient. CAD/CAM technology was used in the presented case to analyze the inter-occlusal space. The case report documents a practical, digital approach and discusses the advantages related to treatment time, ease of treatment, and predictability.

Complex Case Rehabilitation in Light of New Technologies
This case report describes a step-by-step full arch restoration (upper and lower), rehabilitated utilizing new technologies in dentistry. CAD/CAM technology has changed not only the technician's working process, but also the clinician's, offering new benefits to clinical workflow.For example the possibility of using zirconia and its characteristics as a restorative material. The clinician's and technician's professional backgrounds and relationships are critical to achieving optimal aesthetic and functional results; while prosthetic success depends upon an in-depth knowledge of the materials and their properties and on carefully performed clinical procedures, which are still of utmost importance to obtain satisfactory results.
