Lifting, Moving Over-Denture…Leading Burbank Dental Implant Dentist Reviews Reasons Why. (3 min Video)

dental implant denture burbank Dentures lift and move and dental implant overdentures can too!  In this video shot in my Burbank office, I review some of the common problems that can lead to a denture supported with dental implants to lift up when you chew.  Your anatomy can also contribute to a denture that moves.

Careful planning and an understanding of your unique situation can help reduce or eliminate your denture or overdenture from lifting.

Dental implants are the best denture adhesive!

Snap In Dentures on Dental Implants – Burbank Dental Implant Specialist

Snap in dentures is a term some patients use when they come to see me for dental implant dentures in Burbank.  There is a product called the "snap on smile" that is not related to implant dentistry. 

Snap in dentures are dental implant overdentures.  That means they go over dental implants.  The more implants you have the more stable the dentures.  Just as important to the number of implants is the spacing between the implants.  The more space between the implants, the better. Overdentures are not fixed bridges.

Snap in denture burbankSnap in/on implants are dentures!  It is important to remember that.  They are dentures that snap in, they are not porcelain or "real" teeth.  You must remove them and clean under them. 

I performed the surgery and made the teeth for the examples below.

Snap in dentures are wonderful!!!  They are best for the patient that has been wearing dentures for many years. Someone who is already used to dentures is the best candidate. 

They are NOT wonderful for someone who is just about to lose all their teeth.  If you are about to lose all of your teeth or all the teeth on one arch, you are more used to SMALL natural teeth, not an acrylic denture that has the pink plastic covering the roof of your mouth and check areas. A fixed bridge is a better option for this situation, but sometimes a snap in denture can work well.

IMG_8757 How many implants do you need? Snap in dentures typically use 2 -4 implants on the bottom and 4-8 implants on the top.   The overdenture can be made to look extremely life like if a very high end dental lab is used…very similar to natural teeth. The denture will feel stable and secure.

Lower dentures are more challenging than upper dentures because there is no suction to hold them in. This lack of suction, along with jaw and tongue movement during chewing and speaking can cause a lower denture to be very uncomfortable and sometimes painful. The lower denture simply floats on the ridge where the teeth used to be and does not stay in by using suction like the upper. Because lower dentures slip and slide, and as a result cause continuous gum pain when eating, the snap on denture option is a must for lower dentures. For many patients, it is the minimum standard of care for a satisfactory quality of life.

Most of the time I see new overdentures that are made very cheaply using "economy" teeth.

If your current dentures fit well and look good, I can usually reline them to convert them to snap in over dentures.

Keep in mind that the surgery is much more advanced than replacing a single tooth.  This is because you will have bone loss if your teeth have been missing more than 3 months.  Placing implants in areas of thin and deficient bone requires substantial skill and experience.

Mini implants used for snap on dentures are often only a temporary solution but are often marketed as a "permanent" solution.

I have treated patients as old as 91 with dental implants. A healthy 91 year old can have implants while an unhealthy 50 year old may not be able to.

Can I Replace My Dentures With Dental Implants? Burbank’s Ramsey Amin DDS explains

"When should a denture be replaced?" “Can I replace my dentures with dental implants or an implant overdenture?” These are two questions that patients in my Burbank, California office ask on a routine basis.

There are instances where your dentures may have been replaced after 1 year or less, and on the opposite side of the spectrum, there are people who have worn the same dentures for 25 or more years. These ranges obviously are extremes.

Between four to eight years is the ideal. This would seem to imply that the average denture fabricated from contemporary materials will wear out and deteriorate within that time and/or the average denture patient's jaws have changed so much that a new denture must be redone. Each individual's denture needs are different. There are many factors that I take into consideration when evaluating the need to replace dentures.

Denture Longevity Considerations
Lost vertical dimension: The proper linear distance relationship between the upper and lower jaws is called vertical dimension. This is unique for each individual.

IMG_5612 
As one's jaw changes and the ridges upon which dentures rest shrink, a denture becomes loose and vertical dimension begins to change. Additional plastic (acrylic resin) is added to the inside of a loosening denture (called relining a denture) to stabilize it by reducing looseness caused from jaw shrinkage.

The current position held by most dentists is that when vertical dimension has been lost by three millimeters or more, a new denture should be fabricated in order to restore vertical dimension and maintain functional health.

You may have worn the same denture for extended periods with considerable loss of vertical dimension over time. Since vertical dimension loss is a slow, but nevertheless progressive, process, you may have gradually adapted to a continually increasing closed bite position. These individuals often have a sunken facial

Permanent Dentures and Teeth – Is it Possible With Dental Implants?

You may hear a radio ad that talks about "permanent" teeth or "permanent" dentures.

Permanent is a very strong word and may not be completely true. It may be a marketing tactic only.

A major implant manufacturer even says it!

Dental implants are fantastic, and they are the closest thing to being "permanent."  Dental implants are the best tooth replacement option available. The implant is the part that goes in the bone, but either porcelain teeth or dentures have to be attached to them.

Permanent dentures do not exist.  The overdenture that is made on top of the implants will wear out just like any other denture will.  The teeth on dentures are plastic, so they do wear out every few years and need to be replaced. Porcelain teeth whether they are made as a crown on your natural tooth or on an implant can chip or break necessitating its replacement.

Don't get me wrong…dental implants are the best, but don't let someone tell you that the teeth are the last ones you will ever have.  I would be very leary of a dentist in Burbank, Glendale or South Africa for that fact who said dentures or implant teeth are "permanent."

You should be aware of the real and honest facts that implant teeth may need to be replaced…especially dentures.

Bottom line: The implants in the bone are not replaced often, but the teeth on top of the implants can require maintenance, repair and even replacement. 

Here are some related articles that I wrote:

Partial Removable Denture vs. Dental Implant -An Example

Look at these pictures I took just the other day:

IMG_3514
IMG_3520 
These are pictures of my patient's partial removable denture to just replace one front upper tooth and one side tooth…wow that is a lot of metal!

It takes all those hooks and clamps to secure his two missing teeth! 

Partial dentures damage the teeth they hold onto over time.  Most commonly they break off or decay at the gum line causing the partial to get bigger and bigger and eventually become a full denture. Even teeth with crowns that touch the partial get recurrent cavities and decay. Your palate is either fully or partially covered if it for your upper jaw.

IMG_3515 
He is considering an implant for the front tooth because he now notices that his other front center tooth is now loosening.

Partial removable dentures speed up the process of tooth loss.

The bone in the area of the missing teeth continues to shrink from disuse atrophy.

All of this can be replaced with just two simple dental implants.

Zinc Poisoning from Denture Adhesive? Burbank Dental Implant Dentist Review

This is very new information that is yet another reason to have dental implants rather than using messy pastes and liners to hold in loose dentures.

Zinc is a component used to make denture adhesive.  When you use excessive denture adhesive paste, you ingest zinc.

Excessive zinc intake may cause problems in the blood and nerves of your body.

There is no need for denture adhesive if you have an implant overdenture or have fixed dental implant bridges.

Below is the actual letter sent out to all dentists. If you wear loose dentures and use these products, I suggest you read this carefully. I have highlighted the important parts.

Please ask any questions in the comments section below.

Dear Doctor,

This communication is to alert you of the potential health risk from long-term excessive use of GSK's zinc-containing denture adhesives Super Poligrip 'Original', Super Poligrip 'Ultra Fresh', and Super Poligrip 'Extra Care.' As patient safety is our foremost concern, as a precautionary measure GSK has voluntarily stopped the manufacture, distribution and advertising of these products. GSK has discussed this situation with the FDA and no further action is required.

GSK continuously monitors published scientific literature and the adverse events we receive in relation to all our products. There is a variety of sources of zinc and it is an essential part of a healthy diet. However, in 2009 we received an increased number of adverse event reports. Together with the published literature", these suggest that excessive use of these products, typically for several years, may lead to the development of excessive levels of zinc in the blood (associated with copper deficiency). The reports describe the development of myeloneuropathy and blood dyscrasias. Neurological symptoms may include sensory disturbance, limb weakness and difficulty walking. These reports are very rare, given that several million people are users of the products.

It is important to note that zinc is not absorbed through the mouth, remaining bound to the adhesive and is only absorbed when swallowed. A small amount of adhesive is swallowed during normal use. This is not considered to be harmful.

Patients who have used Super Poligrip 'Original', Super Poligrip 'Ultra Fresh', and Super Poligrip 'Extra Care' in accordance with the instructions may continue to do so safely. While the majority of patients do use these products safely, some patients apply more adhesive than directed and use it more than once per day, usually due to ill-fitting dentures. These patients have been advised to consult their dentist for advice.

We have instructed denture wearers who have used GSK zinc-containing denture adhesives Super Poligrip 'Original', Super Poligrip 'Ultra Fresh', and Super Poligrip 'Extra Care' in excess of the product directions for several years or are concerned about their health to discontinue use, consult with their Doctor and use a zinc free alternative (e.g., Super Poligrip 'Free', Super Poligrip 'Comfort Seal Strips', Super Poligrip 'Powder'). A typical 2.4oz (68g) tube should last 8-10 weeks.

If you have any patients who describe neurological symptoms associated with long-term excessive denture adhesive use, you should refer your patient to their Doctor for assessment. We also ask that you report the case to us toll free (866)640-1017.

How Many Dental Implants Do I Need Under My Denture?

In this post I am specifically talking about overdentures, not fixed implant bridges.

Most commonly, a lower denture is supported with two to four implants underneath it.  The more implants you have the more stable the denture is.

If I gave you a stool with two legs, could your sit on it?  Yes you could!  It would take some balance on your part, but you could sit on it.  An overdenture with two implants, works like that.  The denture is held in very strongly, but it can still move in the back.

In a two-implant overdenture, the implants are purposely placed in the front part of the jaw.

125_2565

If you added a third leg to the stool, would that make it more stable?

3 implants ramsey amin

Of course! Especially if the three legs were equally spaced away form each other.

The average denture has fourteen teeth on it.  So the more implants, the better.  Four implants are the best option for stability.  It is a four-legged stool.  The implants make the overdenture even more stable when a bar connects all the implants.  This “splints” them together and creates strength in numbers.

Implant attachment mechanisms IMG_8216

IMG_8212

Even two or three implants and be splinted together with a bar for added stability.

Image16 IMG_1505

Five or more implants in the lower jaw is usually strong enough to replace the denture all together!  Meaning the teeth would no longer come out.  They can be fixed in place.

The upper jaw generally requires six implants to have a non-removable fixed bridge.

The basic theme is: the more stability you want, then the more implants are needed.  Also, the more bone you have missing, requires more implants to be stable over time and avoid bone loss on the new implants.

This concept is sometimes confusing.  Please comment below if you have a question!

Dental Implant “Overdenture” Basics – Dr. Ramsey Amin, Burbank, CA

Is your denture loose?

A traditional denture can be supported with implants.  Dental implants will allow you to once again speak and eat with comfort and confidence! They are secure and offer freedom from the irksome clicks and wobbles of dentures. They'll allow you to say goodbye to worries about misplaced dentures and messy pastes and glues.

A removable full denture is connected to a bar attachment, which in turn is anchored on two to six implants in the jaw. The implants help keep the denture securely in place and provide better function and comfort. It actually snaps and locks into place. With four to six implants and the connector bar, this option is extremely stable and almost feels like natural teeth. Overdentures also replace lost gum and bone and can vastly improve facial appearance. Cost is usually the reason why this solution is chosen over a fixed bridge.

A fixed bridge is not removable.  A removable overdenture has implants under the denture.  An overdenture is a great solution for someone that already has dentures. Many times I can use your existing dentures and just attach implants to them!

An upper denture usually needs more implants than a lower one.  This is due to the soft bone of the upper jaw.  The worst thing you can do is "under-engineer" any overdenture.  They endure a tremendous amount of force and will fail in a few years if they are poorly designed or have to few implants.  It would be like constructing a building and skimping on the foundation.
