Ana, I have had great success with these type repairs but using composite resin I expect them to last as a typical class V restoration with the exception of the bond to porcelain. That bond will be as good as any porcelain repair technique so I estimate the total repair to last from 3 to 7 years and needing refinishing periodically. No doubt the restoration helps protect the tissue and even stops cervical erosion.

Hi Dr. Goldstein, I enjoyed your video very much, I find this is a very practical way to extend the life of restorations that are esthetic failures yet still with great function. My question is: what would be the durability of these restorations? and supposing there was no over-contouring and the restorations are well polished, would you say this treatment HELPS the perio condition or affects it? Thank you for sharing this with us....

Great case Dr. Goldstein! Ricardo Gapski

I generally like to use air abrasion for all repairs to porcelain except when the use at the gingival area might initiate bleeding. So even then I sometimes use altered gingival margin trimmers to protect the tissue. Although hard to apply in these areas if possible I also like to apply a rubber dam or substitute. The benefit is to get micromechanical retention.

Hi sir, thank you for the video. When would you use air abrasion on the porcelain? Maybe for a bigger defect? You would use SiO2 for the abrasion?

I was referring specifically to Venus Diamond but also , Estelite Sigma Quick is technically a "supra-nano" composite. Estelite Sigma Quick's filler is 200 nm (nano meters) in size, which means it is larger than a nano but smaller than a microfil.

I currently use filtek supreme plus which I believe is a nanocomposite that 3M classifies as a nanohybrid, is that the same as the microhybrid you refer to?

Ronald Goldstein - (9/12/2010 7:24 PM)

Pink opaquer can be an excellent way to neutralize the gray coming from the root surface...Have you tried some of the newer microhybrid nano composites?

Biofunctional Dynamic Occlusion
Biofunctional Dynamic Occlusion is a comprehensive approach between occlusion, posture, and function. Overall, this lecture will create an understanding and relationship between the cervical spine and mandibular movements and the trilogy between Joints, Muscles and Occlusion. Most of the patients that we treat for dysfunction, were compromised during the early stages of growth and development. Overtime these created accommodations and compensations in the system induced by the physiology of the airway.

Clinical Excellence in Operative Dentistry: Not Only A Question of Color & Fancy Trends
Nowadays the maintenance of “a nice smiling” represents the main desire of our patients and the request for tooth colored restorations is very high. Predictable and repeatable results can be achieved through materials and clinical practices that, on one hand, preserve the original structure of the compromised tooth and, on the other hand, involve a very low biologic price. New technologies for the enamel-dentinal adhesion and the continuous evolution of more sophisticated esthetic materials as composite and porcelains allow the effective reaching of verifiable and predictable results. This lecture aims to point out the relevant guidelines in both direct and indirect techniques for esthetic restorations through the evaluation of techniques and materials in order to reach correct, standardized and long lasting evidence based clinical results.

Predictable Implant Aesthetics Utilizing A Custom Fabricated Provisional Abutment & Impression Coping Premium Member Content

Predictable Implant Aesthetics Utilizing A Custom Fabricated Provisional Abutment & Impression Coping
Mastering the art of predictable implant aesthetics can be challenging. One of the most stressful areas for most dentists is the process of creating a beautiful provisional that will guide tissue and predictably communicate the aesthetic outcome for the final restoration in the aesthetic zone. Combining the use of a custom fabricated provisional abutment, provisional restoration and a custom fabricated impression coping many of the aesthetics challenges can be addressed. This information can then be communicated to the laboratory to ensure the most predictable aesthetic outcome possible. This program is designed to simplify and streamline the entire process of implant provisionalization and impression. This program will provide a systematic, step by step approach to tissue management, provisionalization and impression of implant cases.
