Correction of Tooth Defects and Discolored Teeth Using Direct Composite Resin - Part 4 of 4
Description:
For the past 50 years dentists have been making instant esthetic transformations using direct composite resin. That technology has been enhanced by the latest nano composite materials. Although the past decade has seen greater use of ceramic materials in esthetic dentistry, direct bonding with these new composites is still a highly valuable procedure. This video will deal with correction of severe tooth discoloration using nano composites. Immediate composite resin bonding can act as either the ideal correction or as an extended trial smile so patients can live with their new smile as long as necessary.

Questions & Comments

Rodolfo, when I bond to existing resin i will generally remove the entire restoration if it is defective but if it is merely a color improvement then I cut off the outer surface with a course diamond AND air abrade the surface giving me a good retentive surface. Then I etch to clean the surface, apply bonding resin and reveneer with new composite resin. The reason I use the course diamond on the adjacent enamel is to be able to nicely blend the new shade of composite resin so the new margin will be invisible. Then the extra application of air abrasion is to be able to create a micro-mechanical surface especially if there is additional resin still in place.

my name is Rodolfo Badilla , several questions , 1)when you are doing the bonding and you drill the resins what is the protocol that you use , do you etch the resin , do you sandblast it ? 2 ) don't you think that if you sandblast the enamel would be more conservative than drill it with a diamond bur ?

Farhan,
My technique for polishing composite resins is as follows:
1. Contour and final finish with ET (Brasseler USA or BUSA ) diamonds and burs with final finishing always with the ETUF burs which are 30 blade carbides in either the ET design or the OS design for lingual or occlusal finishing.
2. Next I usually go to a series of sandpaper disc finishing to polish the contours so there are no hard angles. I always try to match the adjacent or opposing teeth and use a large front surface mirror rotating back and forth to give me a really good 3D look at the entire labial surface. This helps me eliminate and hidden depressions or incorrect line angles not easily seen just by looking at the tooth surface straight on. I generally use only the first 2 discs and wait to use the last 2. I always use a drop water to keep the discs wet...never dry.
3. Next, I use one of the impregnated polishing kits that have both point and cup shaped instruments always using water to keep from polishing dry.
4. Now I use the ET 6 or 9 to place my surface texture if the adjacent teeth have texture or if I feel I want to have more light reflection.
5. I finish with the last 2 discs or with the final impregnated bur or cup finisher just lightly going over the tooth surface but never to eliminate the texture but to highlight the raised areas more.
If you pull up my Xpert page I have my articles on composite finishing there and could give you more about my feelings on the subject.

DEAR DR GOLDSTEIN PLEASE ELABORATE ON POLISHING TECHNIQUES

Ronald Goldstein - (8/25/2011 10:40 AM)
Jack, adding composite to occlusal surfaces has been a very good treatment for class one and two restorations but when you try to build up an entire tooth it does have its limitations. I have done this as an interim step before committing the patient to restoring vertical dimension with ceramic restorations. However, chipping and fracturing of some of these restorations becomes the norm within a short time. Nevertheless, it is a very good way to help determine if your final prosthetic restorations will be successful and the TMJ will respond favorably. So, no, I would not suggest composite resin as a final full mouth restoration.

Dr. Goldstein,
its Jack here from Australia. Im just wondering, what do you think of full mouth build up with composite? with regard to occlusion, how would you open the bite, if you are doing a erosion case, where most of the anterior teeth are all worn down.
thanks

Dental Ceramics: Material Properties and Clinical Applications - Part 2 of 3
This presentation will give viewers a background of the physical and mechanical properties of current dental ceramics. The material properties of the ceramics will be used to explain clinical recommendations for selecting a restorative material and designing the prosthesis. Additionally, laboratory research data will be presented to help the clinician determine the best method to cement or bond an all-ceramic restoration. Finally, an overview of laboratory fabrication of all-ceramic restorations will be presented in order to show clinicians their options when sending out a laboratory prescription.

Color in Esthetics: The Science Behind Beauty
This presentation will be very different from programs in color matching, communication and reproduction of natural teeth that you may have attended in the past. The didactic part will emphasize the nature, principles and fundamentals of color, and tools that are essential to master a plan for successful color matching in both office and dental laboratory, together with step-by-step instructions. Examples and practical suggestions will be provided, including the latest changes recommended by the presenter. Dental Color Matcher, a color education and training program for esthetic dentistry authored by the presenter and used by dental professionals and students in 100+ countries, will be demonstrated.

Immediate Implant Provisionalization: A Critical Aspect in Tissue Care and Esthetics-Part 2
The management of the hopeless tooth or an edentulous span in the Estheitc Zone is amongst the most clinically demanding procedures in tooth replacement do to the demands of tissue preservation and patient management during the healing phase. As important as the implant surgical process in these areas is the role of the immediate provisional restoration. Tissue support, emergence profile and The provisional restoration phase of implant therapy has become one of the most critical steps in immediate or delayed placement for several reasons including the following...

Planning & Finishing Techniques
Longevity and optimal aesthetics are critical aspects to consider when planning for direct composite resin restorations. While strength, wear resistance, and superior micromechanical retention are typically associated with functional durability, during the planning stage clinicians must equally consider aesthetic longevity, which includes retension of the original morphology, color stability, stain resistance, and marginal adaptation. To ensure optimum results for direct composite resin restorations,…

Visagism: The Art of Dental Composition
The aim of this article is to present a novel concept: Visagism. The Visagism concept helps dental clinicians
provide restorations that account not only for esthetics,
but also for the psychosocial features of the created image,
which affect patients’ emotions, sense of identity,
behavior, and self-esteem. These factors, in turn, affect
how observers react to patients following treatment.
