Dr. T. asks:
I have seen advertisements for Flex Star V (Nobilium/Ticonium) for fabricating flexible removable partial dentures. It looks similar to Valplast (Valpalst International) which I have used with great success. Patients like these a lot better than their old metal framework removable partial dentures. Far more comfortable and much better aesthetics. I am thinking of trying a few flexible removable partial dentures using this material instead of Valplast. Any comments? Have any of you tried it?

I would love to hear about your success with Valplast because I have not had great results. Unless I put rests on the teeth, I have had periodontal issues.
Also…impossible to repair.
When you incorporate metal rests into the removable partial denture framework, how much of a metal framework do you need to support the rests? Do you also need metal major connectors? Do you need metal minor connectors to connect to the metal rests? Is it possible to have the metal rests without using much metal?
You need enough metal to imbed in the Valplast material. You may use metal frameworks with Valplast processing for esthetic clasps. Repairing Valplast is not necessary. It does not break. If teeth have to be added it is not problem for a Valplast lab. If a lab tell you it can’t be added to means they can’t. A good accurate alginate impression in an oversized stock tray is actually best to get a good passive tissue impression. Impinged tissues during impressing can mean a nightmare of adjustments–which is not as easy as adjusting acrylic–but your lab can help with that.
the problem with all these material is you can’t add any tooth or flange with the conventional self-cure acrylic by the chairside, and it can be difficult to explain to the patient who doesn’t want to wait a few working days.
Can you use the Valplast dentures for Kennedy Class I and II situations where you have distal extension saddles?
Do you have to use metal rests on the terminal abutments for these kinds of cases?
Are those flexible materials biocompatible ? is there any research made on them? I did not use them before, if you can help me.
hello friends, valplast is one of the greatest dental appliances in our time. there is no teeth prepping.no shots. the valplast partial just disapears.
Can you use Valplast for a long edentulous span replacing several teeth?
I have used Valplast extensively and have made enough mistakes to feel better about using it in the future (case selection is very important). A couple of issues:
1. Patients love it because it does not show clasps and it is thinner than a regular acrylic provisional.
2. It is great as an interim prosthesis (see “Boomer bridge- Kellar Labs) if you are not directly loading an implant.
3. Best used in Kennedy Type III (”tooth borne”) situations. Trident can add some nice acrylic occlusal rests if you prepare sufficient space. Distal extension situations longer than one tooth tend to flex off the ridge under function, leading to a feeling of instability, decreased function and sore spots. Glidewell does a nice job of hybridizing Valplast partials with a metal major connector to provide needed stability.
4. Watch out for soft tissue undercuts in areas of retention. These lead to extreme sore spots (since the Valplast is not often tooth borne it tends to flex around the retention in function). Also, I have seen some severe gingival recession occur from all this extra trauma. Periodontally, the clasp position (at the gingival crest) is potentially damaging to gingiva. Adjusting the clasp areas to relieve this can result in loss of retention.
5. In general, I don’t recommend these for anything other than provisional situations. However, I have had several patients who have successfully worn their “provisional” for at least 3 years.
Dr. T as for Flexstar and Valplast as a technician I get the same question from all my clients is how do I adjust this material? So I have researched and switched my clients to Duraflex which can be adjusted with a cross cut bur a very natural color and it allows the tissue to show through and blend into the mouth very nicely. As per your question both Flexstar and Valplast are quality materials however the adjustablity in your office is difficult with out the right tools. Flexstar is pretty much Valplast but a bit more ridgid. Which all this means is less sore spots under clasp for the patients. However Duraflex you can make really thin and it is still rigid enough to keep the partial stable enough to keep down the sore spots. All of the flexible materials on the market today can be added to and relined. Some of the comments listed I get all the time doctors you are correct on distal extentions causing sore spots this is a failure by the lab there is no need for metal reinforcement. The lingual of the partial should be thicker to stablize the appliace to reduce lateral movements of the partial. On uppers the design should be a ap bar since you do not have as much ridge as the lower. As for occlusial rest I do them however it is not necessary this is a tissue bourne partial so it is a fee that your paying for and it is not needed. These materials have been around since the fifties and have been modified and profected by various companies. Using this on a cast framework is fine to obtain the esthetics. If you or anyone have any questions on flexible materials I would be more than happy to share everything I know. Thanks for the chance and I hope this has helped with your questions.
my valplast(upper) has 8 teeth now,recently lost crown and tooth that was used to secure,so now that side floats ,can avalplast be anchored withan implant,whats my option, please help
Yes Does a Flexible Partial have to flex from saddle to saddle What would happen if a company would come out with a light cured flrexible Partial and eliminate all the stone and remakes and repairable. But not indestructable. What would you guys think of that ?
I have a question for you techs and Dr’s What are the negatives about constructing a Flexible Valplast Partial and what are the positives. Do the saddles have to touch to be a good Flexible partial Or is it that the patient likes it because its light and feels like there is nothing in the mouth. What if you could construct a Flex partial and not have to use stone or heat up the material and not have to knock out the case and find stone enbedded into the plastic. What if you could wax up a Flex partial using a light cured material and get out what u see your putting into the light. Does the Flex partial have to be durable like the Heat cured ones . What if you could repair Flex partials? Here are some questions fopr you to answer for me?
I don’t think many know the bad side of flexibles.As self cured acrylics,they stink.Properly cured heat cure acrylics don’t stink.Try rubbing a using flexible denture with stone bar and you can get that bad smell.I hate that smell and may be some patients feel the same.
Case selection is the key. Valplast is indeed a great material, patients love them for esthetics but I still limit my use of valplast material to cases which are short span and tooth bounded. I wouldn’t recommend it for long span cases specially in free-end cases because the load will be concentrated on the residual ridge. Valplast is flexible, if you use it on a free-end case… you can imagine it will have a “diving board” effect.
For prevention of fracture of full denture,is flexite useful?
I have Valplast partial denture. The product smells plasticky in my mouth and mouth retains that oodor even when the denture is out. It never goes away. Can you tell me why and what I can do?
For Darena: I am contemplating getting a valplast partial & am bothered by what you report. I assume you are aware of the product the company makes for cleaning your partial, and have been on the valplast website for their instructions. Is this not so?
And have you gotten any help from your dentist regarding the offensive smell? Thanks.
Also interested in more honest reviews.
To Freyda, I did not know about the cleanser but have used Scope to soak it in (per my dentist) as well as over the counter cleansers. The real issue is my mouth smells of it after I take it out-even if I leave it out a day or two. My dentist said he never heard of this and he would call the company. I will keep you posted.
I have worn a valphast partial (seven teeth/upper front) for three years. It wears very well and has never caused an odor in my mouth. I do get sore spots occasionally. I can tighten the partial by running it under hot water for a minute or so and push in where loose. I soak in efferdent nightly or a minimum of 15 minutes. I recommend using Arm & Hammer baking soda and hydrogen peroxide tooth paste or mix your own. You can also mix hydrogen peroxide in water for use instead of regular mouth wash.
I requested specifically to have cu-sil partials. I now find I have a mouth full of metal. I signed a release before my first visit. Is it routine practice for a dentist to make the final decision regardless od the patient’s wishes?
Do I have any recourse to get what I asked the doctor for?
My dentist has recommended a 2 tooth Valplast denture for me. Can anyone give me an idea what that should cost?
Thanks,
question for the technicians..
is valplast the best material for flexible dentures out there? if not witch is the best option? open to any opinions. thanks
Am missing the top back left teeth (3 back molars) due to failed bridge, root canals, abscesses and crowns that eventually killed these three teeth.
I seem to be a bad candidate for implants (probable infections).
Valplast sounds like a good alternative to avoid sacrificing any more teeth by attaching metal wires to the partials for me?
BTW, 3 of my grandparents had full dentures by 45 years of age. One parent has two bridges and the other multiple partials on top and bottom. Sigh.
Thoughts?
Thnx!
I had emergency extractions early this year (3 on the bottom and 2 on the top). One of the extractions on the top was my left front upper tooth.
The dentist gave me a metal partial on the bottom to compensate for my extracted molars. I’ve not had a problem with that.
However, he gave me a Valplast partial on the top. I hate it. It’s uncomfortable and interrupts my speech. I am a vocalist and this has caused me so many problems. I also spend a lot of time on the phone at work and people have trouble understanding me.
Also, it starts feeling “soggy” after a few hours and no amount of washing or rinsing seems to be able to fix that.
I went to a different dentist to get a metal partial on the top. I’ve done research on the internet and found that other vocalists with Valplast partials have had problems, even after months of speech therapy, so they switch to metal and things are fine after that.
The dentist is recommending instead an implant in the front and then a metal partial to cover the 2 missing back molars on the top. So, more money. *sigh*
But, I suppose it’s worth it just to be able to pronounce words properly again.
I’ve read that some people love their Valplast partials. Do some more research on them. For me, it’s really caused me problems.
Thank you.
Can you tell me about ultraflex denture and how long it is warranted for. I am thinking of getting this type of denture. Thank You. Mrs. Hoeppner
Hi, I am considering a valplast partial. I am really afraid and I really can’t afford the $2000 that the dentist is asking for so I really hoped this would make me feel less ashamed of my appearance once he takes out 6 teeth. Can some one help me with the decision to get valplast or some other flexible partial.
signed,
Totally Confused
CAN I GET AN OPINION ON THE COST OF THIS FLEX STYLE BRIDGE, I AM LOOKING FOR AN UPPER NEED TWO TEETH EACH SIDE.
WILL IT BE RELIABLE OR NOT LAST TO LONG,
PLEASE ADVISE.
