Dental Implant Retained Dentures


The main reason patients come to us for implants is because they can't tolerate their dentures.

Patients then have two main options

1. To replace the denture altogether
with Implant retained crowns and/or bridges.

2. To make their denture more useable.

For many patients, specially with either no teeth or very few, the first option is either unaffordable or unattainable.

The vast majority of patients fit into the second group and we can offer them options that are good and affordable.

Full removable dentures can be an everyday pain in the neck. It makes normal chewing impossible, you cannot enjoy the taste of food due to its palatal plate.

Heat and cold sensations also get worse, moreover, it keeps moving which is really annoying. You can never get used to these inconveniences.

Neither denture adhesives work out: it is a real chore to clean that sticky material and it does not last too long...

More importantly, gum recession makes its yearly reline necessary, to keep its position in the mouth.

Modern Solution:

Over-Dentures Combined With Dental Implants

Denture Stabilisation with Dental Implants

You would not believe how much better you could use your dentures if they were stabilised with implants, even two or four of them.

This totally puts an end to denture movements. No need to use denture adhesives, no need for palatal plate, like in case of conventional dentures.

Thus, your taste, heat and cold sensations will improve. You wil be able to chew just as before losing your own teeth.

You are recommended this solution if you would like a good, yet economic solution for stabilising your conventional removable dentures.

There are two main options Implant Retained Dentures. The Removable dentures maybe supported by 2 or 4 implants.

1. Dentures with ball (push-button) and locator attachments

2. Bar-retained overdentures: with the insertion of 4 implants

Push-Button-retained overdentures

These are done with the insertion of 2 implants.

The Locators

Lower denture with ball attachment (push-button)

. Upper denture with locator attachment

This solution is suited for patients who have some residual ridge and the looseness of the denture is minimal

Where there is less ridge then the Bar Retained Denture is advised

But the choice will be made based on the extent of the improvement required and the patients budget

Bar-retained overdentures

These are done with the insertion of 4 implants.

Bar-retained denture, lower

What are Same Day Teeth with Dental Implants (All on 4)?

All On 4

Same day teeth with dental implants (or All on 4) is a technique that uses four dental implants in restoring a full arch of teeth (either the lower or the upper arch).

This method of placing the implants is less-invasive compared to a traditional dental implant treatment, making it possible for the treatment to be completed without the need for complicated procedures – such as bone grafting – even if there if the jawbone structure is considered inadequate.

Also called same day teeth or same day implants, the all on 4 method enables you to enjoy a brand new smile in just a single dental appointment.

You can enjoy the benefits of an implant treatment (with a fixed bridge or dentures) after just one visit to the dentist, with all on four dental implants.

What does the All-on-4 procedure entail?

After your consultation with the dentist, a whole jaw OPG Xray and possibly a CT scan will be taken to examine the anatomy and location of bone in your jaw.

This will allow your dentist to diagnose if there is enough bone length, width and density to securely place All On 4 Dental Implants

A thorough examination will also be performed to check that there are no problems present in the mouth before commencing with your treatment.

Placement of the four implants is the same as normal implant procedures. Treatment is carried out in a near sterile environment similar to a hospital, with the surfaces and surgeons scrubbed and covered.

The operation is carried out under local anaesthesia and is pain-free. We also offer sedation by a medically qualified doctor. The implant fuses with the natural bone over time. This process is called osseointegration or osteointegration and gives the replacement teeth maximum stability.

Two of the All On 4 Dental Implants are placed at the front of the mouth, taking advantage of the dense jaw bone existing there.

The two implants at the posterior of the mouth are fitted at slopping angles to allow maximum stability and take full advantage of the stronger bone in front of the jaw and avoid the maxillary sinus’s in the upper jaw.

There is no need to wait for the mouth to heal before placing bridges or dentures on the implants with All-on-4 implants, so the patient leaves the surgery with a full set of functional and beautiful teeth.

The treatment remains popular and is generally successful when performed by an experienced Implant Surgeon.

How are All on 4 implants different to normal dental implants?

All on 4 dental implants are unlike traditional implants because 4 implants are used to sustain a whole arch, when usually between 6 and 10 implants are needed to maintain an arch.

All on 4 dental implants are able to sustain an arch because of the angles the implants are positioned at, with the back implants positioned at a 45 degree angle rather than a 90 degree angle, which helps to lock the implants together.

As only 4 implants are needed the procedure is quicker and less invasive.

What are the benefits of All-on-4 Dental Implants?

Only requires 4 implants instead of the usual 6 – 10

All on 4 Dental Implants are carried out far quicker than traditional methods with less surgery

Less costs involved than standard placement of 6-8 implants

Bone graft unlikely to be required, which also reduces the cost

Permanent set of teeth can be fitted in the same appointment as the implants

All on 4 Dental Implants are a great way of preventing the inconvenience of denture looseness, slippage and wear, which helps when eating and talking, and allow the new teeth to be treated just like regular teeth.

Those who have All-on-4 dental implants experience the same ability to eat as people with a full set of natural teeth and will experience no difference in taste, i.e. the ability to eat hard and sticky foods which are normally challenging to denture wearers.

The teeth of All-on-4 do not rub against the gums (thus no ulceration with denture wear) as they are securely anchored into the dental implants.

All-on-4 replacement teeth are fixed permanently in the mouth and can be cleaned just like natural teeth. In time you will not think about the fact that you have implants.

High implant survival rate.
Short term: 97.5%-100%,
Medium term: 96.7-100%,
Long term: 94.8%
(Faculty Dental Journal Jan 2012, Vol 3 Issue 1 page 25).

Am I suitable for All-on-4?

Before beginning treatment the dentist will perform a thorough assessment to ensure suitability of treatment.

Dental Implants have the highest success rate when performed on suitable candidates. Factors posing as risks to success are if the patient is diabetic or smokes heavily.

Smokers must note they are two and a half times more likely to experience failure than non-smokers. However, this does not preclude smokers from having implants.

Those who suffer from gum disease will need to have the condition dealt with prior to proceeding with implants. Treatment may be a professional clean by the dentist (to decrease bacterial count) and a continuation of good oral hygiene regimes at home.

For severe cases of gum disease a more intense gum treatment performed by a periodontist may be necessary. It is important the patient understands the importance of good oral hygiene and is able to undertake daily brushing and flossing using correct techniques prior to the placement of implants.

You should discuss your suitability with your dentist before contemplating undergoing the All-on-4 treatment.

What are the risks of All on 4 Dental Implants?

As with most dental treatments, there are risks involved when placing All-on-4 implants.

Although unlikely, you may experience some pain and swelling in the implant area after the All-on-4 implants are placed. Over the counter pain killers should help with the discomfort until it resolves. However, the procedure itself will be pain-free.

Your dentist will use x-rays or CT scans to determine the exact position of the many nerves which are in your lower jaw. These nerves supply your tongue, chin and lower lip and teeth; if they are disturbed or damaged during the implant procedure, you might experience tingling or numbness. Every effort will be taken by your dentist to avoid this happening.

As you can imagine, the amount of stress and force when biting and chewing can put great strain on the jaw bones. It is therefore important the quality of the bone is good enough to cope with the pressure. Otherwise this can lead to the implant not fusing with the bone properly, and possible failure.

It is important you weigh up all of the pros and cons when deciding if All-on-4 is the right approach for you.

Can both upper and lower teeth be restored by the All-on-4 treatment?

Yes, both can be.

Will final restoration be natural-looking?

Yes, it will be natural-looking, indeed. Our Implant Dentists personalize the treatments, therefore their high level of expertise and their cooperation with patients will result in a smile you have always dreamed of.

Is it going to be painful?

All on four surgical procedure is painless due to local anesthetics given by the oral surgeon. However after the procedure minimal amount of swelling and pain may occur on the face.

How long does it take to recover after the procedure?

Although All on four surgery is painless, after the operation when anesthetics is gone you will feel pain, swelling inside the mouth or even on the face. In case of strong pain it is indicated to take some regular painkillers because they might help you handle the first days after the surgery.

Most of our patients can return to work within 2-3 days, but there are many who start working the next day after surgery.

Since our surgeons use resolvable stitches, you do not have to come back for the removal of the stitches so you can spare an extra journey.

The dental implants placed in your jawbone need four months of healing before the All on four fixed denture can be placed in your mouth.
