A: A dentist can use Uveneer:
- for all composite veneer applications, for one or multiple teeth, and also for the creation of temporary veneers and crown shape between appointments while porcelain veneers are being made in the lab
- for direct chairside mock-ups before conducting the procedure to show the patient how the results can look.
- for communication with lab technicians and orthodontists.
Q: How does Uveneer work?
A: A translucent template is pressed over the composite that has been laid on the tooth after etching and bonding. The template is removed after the material has cured. The template is easy to handle and has a non-stick surface.
Q: What prompted this innovation?
A: Whilst composite materials continued to develop and improve, the method of direct composite veneer application remained unchanged. Dr Sigal was frustrated that she couldn’t achieve perfect results each time and that the process was so time consuming. She decided to do something about it.
Q: Can Uveneer increase practice profitability?
A: Yes, dentists who use Uveneer report that they are performing many more composite veneer procedures than before because they find the process so easy, quick, predictable, and affordable for their patients, with high case acceptance.
Q: Is there a learning curve when first using Uveneer? How do I start using it ?
A: Uveneer is easy to use. Like all new tools it can take a little practice to become proficient at it, but that’s half the fun. The strength of the Uveneer system is that if you aren’t 100% satisfied with your initial result, you can just remove a little layer with a bur and again press the Uveneer template, with more composite or flowable composite in it, onto the tooth. You will quickly learn, after one or two trials, how much pressure or how much composite to apply to the template. For beginners we suggest doing a mock-up on the patient, creating a composite veneer with Uveneer, without etching and bonding – this way you can evaluate color and shape without committing to the result. We also recommend, when first starting out, that you work on single-teeth rather than multiple-teeth cases. After gaining some experience and confidence with our easy-to-use template, you will skillfully manage bigger cases.
Q: Dear Dr Sigal,
I was at your hands-on course and start useing Uveneer and I am very happy with the results, but I have a problem- the Veneers changed colours after a month and half. The patient is smoking. Can you recommend what do I need to do?
A: Dear Dr,
Typically composite will pick up stain from smoking, red wine, coffee, tea and certain foods especially if the composite is under-cured. In addition, if a layer of flowable composite is used as the top surface layer, keep in mind that flowables have a low amount of filler hence they can stain and/or change color. If a flowable is used onto Uveneer, as the top surface layer, it should at least be a heavy flow with more filler particles, for example GC Genial Heavy flow or Premise by Kerr.
You can under cure composite but cannot over cure it.
Using a strong curing light is vital. I like to use Valo by Ultradent. This is an excellent curing light and gets the job done. Otherwise, check the output of your curing light.
Moving forward for this patient: Use a bur to remove the top layer of stained composite. Etch, rinse, bond, cure and add a new layer of composite with Uveneer and cure through the template. I like to use Vit-l-escence composite as it has excellent color stability, shine and is micro hybrid composite hence no additional flowable is necessary.
Q: What are the main advantages of using Uveneer?
A: The main advantages of Uveneer are that the dentist can use any preferred composite material; the results are consistent and predictable with regard to final tooth shape, shine and smile design; and it is very easy to use. It saves valuable time because there is no need to spend time carving and minimal tooth preparation is needed. It is also cost effective for both patients and dentists.
Q: Will the shine from Uveneer last?
A: The shine from Uveneer lasts and continues to look like a natural tooth because the template is used as an oxygen barrier, preventing the air-inhibited layer.
Q: How does this system compare with the prefabrication of composite veneers?
A: Unlike prefabricated veneer systems, with Uveneer dentists use their own composite and can also use layering techniques if needed. The Uveneer process removes several shortcomings of prefabricated systems such as thickness, sizing and shade restrictions, cost, and stock holding.
Q: What sizes are the templates?
A: The Uveneer template set consists of 32 templates: 16 medium templates and 16 large templates.
Both medium and large templates provide two central incisors, two lateral incisors, two canines and two premolar templates for both the upper and lower arches.
Q: How to utilize Uveneer when there is a Class III or Class IV?
A: For a large class III, class IV or to extend the length of the tooth you will apply the composite (don’t use flowable composite) directly on the tooth, fill the missing areas of the class III and IV free hand (always use matrix for separation) with composite then press the Uveneer template onto the composite from the facial side as usual, apply pressure from the palatal side with back of your fingers towards the Uveneer template. The Uveneer acts like your pre -made “silicon key “ but this time from the facial side instead of the lingual side.
Before the composite applied on to the tooth I would clean all the decay, slightly prepare the facial side of the tooth so that the template have a passive fit and then etch, bond, apply composite (high value-Dentin, body shades) and include the facial side as well. in this way you will prevent the “patchy look “in the future due to minor staining.
I use Vit-a-lescence in those cases due to the perfect glossy finish and minimal colour changes.
Q: How can you use it for a peg lateral on the lingual side?
A: There are few kind of peg laterals .One with diastemas (gaps) on distal and mesial side and one with no gaps,palatally intruded or facially protruded .Each case is different .
But I will assume that you are referring to the one with the gaps.
In this case you want to close the gaps and build the facial side at the same time.
1-Place separating matrix .(I recomend to use plumber’s tape)
2-Etch, bond and cure
3-Apply the matching shade composite on the tooth in the same manner as if you want to finish the case free hand, make sure that you close the gaps and apply composite on the facial side as well.
4-Press the Uveneer template that matches the size and tooth number onto the composite that laid on the tooth and with your fingers apply pressure from the palatal side on the composite and press it flat and nice with the palatal side of the tooth, the Uveneer template acts like your silicon key but this time is from the facial side.
5-Remove excess with a probe,(spot curing for 1-2 seconds will help with the cleaning process).
7-Remove any excess material from the periphery with a fine bur and polishing discs at the incisopalatal area. Do not touch the facial glossy surface at the process.
Q: How do you avoid “ledging” in the emergent zone so floss doesn’t catch or make a ledge that can cause gingivitis?
A: Perfect finish of a composite veneer is important step for the health of the surrounding tissue and gums and aids with cleaning.
Before pressing the Uveneer over the composite make sure not to overload the tooth with composite resin, if you apply more then needed you will end up with too much excess to clean .Apply enough quantity of resin as you would to finish the case without Uveneer and even less as second layer can be laid later.
Next to the gingival areas apply minimal to no composite at all as by pressing the Uveneer template you will spread the composite to those areas. Then just before curing, use a fine probe and remove the majority of the excess ( apply finger pressure directly on the template while doing it).
A quick spot cure can also help with removing excess of resin .
After the final curing use extra fine diamond flame shape bur for the final flash removal. For finishing at the inter-proximal areas use a proximal saw and polishing diamond strips.
Another way I would recommend is to use a anatomically curved cellulose strips. I recommend those invented by Dr Paul Belvedere and called ” Marginal Perfect Matrix ” this is a great way to get the perfect margins and once establishing good seal the Uveneer is pressed as a final stage. It blocks the oxygen inhibition layer and creates prefect margins around the gingival area.

Regarding class 4 and fractured teeth: Apply composite to the tooth and at the sam time cover the missing broken area ,then press the Uveneer template and apply finger pressure at the lingual side . Use the Uveneer template like your silicon key from the buccal side, then cure.
Q: Can Uveneer be used with children?
A: Uveneer is very popular with paediatric dentists as they are quick to perform especially in those cases of fracture tooth. Children don’t have the patience to sit for long at the dental chair.
Q: How do we know that the kit is designed to fit up to 90-95% of patients?
Also, a patient who has a wider tooth (or longer) than the template, what you recommend to do?
A: From studies about smile design rules and proportions most of the patients will fit into those sizes as they are the ideal sizes.
Many patients grind off their teeth or will have gum recessions ,in this cases the dentist can adjust the veneer to the desire length with a bur or disc. Or in case of gum recession add some composite next to the gums same as doing class 5 .
In cases of large or wider teeth (5%-10% of our patients) dentists can still finish off the case by pressing the template and blending the excess of composite the periphery after pressing on the template. Please remember those are templates and some small finishing adjustments may require.

Q: What cases are you recommending to use a flowable composite for?
A: The cases that I use it are those cases when the nanohybrid composite will not shiny enough, but if the dentist use microfill composites like
Vita-l-escence ( which is micro-hybrid) it will be shiny without the need to put any final flowable. In case that you want to add flowable composite I would advice to use only heavy filled flowable as it will not stain as much as regular flow.
I use Genial universal flow by GC, beautiful by Shofu and Grandio flowable by Voco.
This is for the final glaze and is added as a last layer only over nano hybrid composite.
Dentist cannot use just flowable composite from the reason that it is too runny and pressing the uveneer will be hard to control and can create air bubbles.
