All Teeth on 4 (or more) Implants
What are All Teeth on 4 (or more) Implants?
Four implants are placed (and in some dental indications five or six implants) in either the top or bottom jaw and a denture or bridge is placed onto the implants. When a denture is used, the denture is made so that it snaps onto the four implants so the patient can take it on and off for cleaning. When a bridge is used, the bridge can be attached to the implants so that it is permanent (where only the dentist can remove it for maintenance) or it can be made removable. The key component of the fixed All Teeth on 4 (or more) Implants system is that the denture is made prior to the surgical day and placed onto the implants the same day the implants are surgically placed.
This denture will be exchanged into a final bridge once the healing of bone and soft tissue is finished and the new three dimensions of oral functions have been successfully established.
Benefits of an implant supported denture:
Denture stays firmly in place while eating, talking or smiling
Enjoy all those foods given up by denture wearers
There are no more embarrassing moments when a denture becomes loose at an inopportune time
No more trips to the restroom to remove food under your denture while at a restaurant
Upper dentures can be made without covering the roof of the mouth which alters speech or gags patients
Bone levels are preserved with the implants which reduces the need for relines
Feeling of confidence renewed
Better aesthetic results as no need for denture components under lip
It is usually the only way to regain a full restoration of facial dimensions, also known as the "oral facelift".
Process of removable style All Teeth on 4 (or more) Implants:
CBCT scan to determine optimum location of implant sites or the need for grafting when insufficient bone present
Impressions taken to have dentures fabricated
Implants are placed in very favourable conditions and the dentures affixed to implants
Healing of implants before making final denture which will have metal reinforcing for 4-9 months
Impressions taken again and discuss any modifications required from initial denture, such as teeth arrangement, colour or flange design
Possible to try in new dentures for confirmation of tooth colour and arrangement prior to processing
Deliver new denture that is removable with locator components.
Process of permanent bridge (zirconium)
The benefit of the zirconium bridge option of All Teeth on 4 (or more) Implants is aesthetics and durability and, most of all, an immediate way to restore an edentulous condition. This may also be done at the same appointment as the last teeth have to be extracted.
The zirconium bridge feels more like real teeth than the acrylic used to make the denture. It is considerably more expensive but worth every penny for those who want the best.
The permanent bridge option of All Teeth on 4 (or more) Implants starts with the same initial steps but the initial restoration will be a fixed and stable metal supported acrylic bridge. The second, permanent bridge can be made from Zirconium or a metal reinforced acrylic base. Both fabrication methods will have a space between the gum tissue and the underside of the bridge for access to cleaning. Some patients with a very high upper lip may not be candidates for the permanent bridge option made from Zirconium as a flange of some sort is required.
The permanent bridge fabrication would start after the six month healing phase and would take about a month to complete.
All of these restorations may also be fabricated as hybrid solutions, meaning that they can be altered from fixed to removable, if any medical condition requires this step to maintain an easier handling.
Please note: ‘All on 4’ is a trademarked term that is used to describe the dental procedure for placing all teeth on four implants, hence the name. Since the name is trademarked, we will use the term All Teeth On 4 (or more) Implants.
What is the cost of the denture style All Teeth on 4 (or more) Implants?
A basic All Teeth on 4 (or more) Implants denture costs about $10,000. This would be applicable if adequate bone is present for the placement of the four required implants. If bone grafting is required to add bone to an area for implant placement, there would be an additional fee of up to $2,000. This fee would be less for a single grafting site.
The basic All Teeth on 4 (or more) Implants denture includes:
• Upper or lower primary denture
• Four implants placed into the bone
• Four abutments (attachment devices to hold the denture)
• Upper or lower secondary denture after initial healing time of six months
What is the cost of the permanent bridge style All Teeth on 4 (or more) Implants?
A basic All Teeth on 4 (or more) Implants permanent bridge costs about $24,000. This would be applicable if adequate bone is present for the placement of the four required implants. If bone grafting is required to add bone to an area for implant placement, there would be an additional fee of up to $2,000. This fee would be less for a single grafting site.
In the case of more implants needed (five and six implants) the costs may rise up to approximately $28,000.
The basic All Teeth on 4 (or more) Implants permanent bridge includes:
• Upper or lower primary denture
• Four implants placed into the bone
• Four transitional abutments (attachment devices to hold the denture)
• Upper or lower permanent zirconium bridge after initial healing time of six months
• Four permanent style abutments to hold bridge to implants.
How long will my All Teeth on 4 (or more) Implants denture last?
The implants supporting your denture will last for 10-20 years. The acrylic denture made to fit over the implants will last 8-12 years. However, most people find the denture will last more than 12 years, but there are some people who will require replacement at the 8 year mark.
What is the cost of a replacement denture for my All Teeth on 4 (or more) Implants?
A replacement denture would cost about $2,000 as long as all abutments and implants are in good order.
In the case of a hybrid denture, where a fixed bridge has to be altered and changed into a removable solution the price may vary between $4,000-$8,000.
How long will my All Teeth on 4 (or more) Implants Permanent Bridge last?
The implants supporting your denture will last for 10-40 years. The zirconium bridge made to fit over the implants will last 10-18 years. However, most people find the bridge will last a lifetime, but there are some people who will require replacement at the 10 year mark.
Zirconium is extremely durable and made to last indefinitely. The case for replacement need is usually abuse, such as using your teeth as tools. Unfortunately, there is no way to repair a zirconium bridge and a new one will be required if a single tooth is broken.
What is the cost of a replacement zirconium bridge for my All Teeth on 4 (or more) Implants?
A replacement bridge would cost about $8,000-$10,000 all long as all implants are in good order. Some restorative parts may be still usable, but a few of these parts will have to be changed.
Can my existing denture be used for All Teeth on 4 (or more) Implants?
The existing denture may be used for the immediate restoration, even if a relining/alteration has to be considered.
Can I decide to get a permanent bridge after getting the removable denture option?
This is possible since the four implants are universal. However, the abutments would have to be changed. Again, the individual case and costs would have to be considered and quoted.
What guarantees are there for my All Teeth on 4 (or more) Implants and denture?
There is a guarantee for five years on the prosthetic parts - If an implant fails during the healing period it will be replaced with no other costs other than the material costs (implant and sometimes the bone graft material).
We offer a free replacement of any implant that fails within the first six months of placement. Once the permanent bridge or secondary denture is made, it is very difficult to place an implant under those appliances.
If the denture or bridge breaks due to a fault in the fabrication, we will replace it at no charge. However, if the denture or bridge breaks due to abuse, trauma or accident, the replacement cost is borne by the wearer.
What is the success rate of the All Teeth on 4 (or more) Implants system?
This procedure is a very safe way to restore edentulous jaws and offers an incredibly high success rate of nearly 99%.
