An implant-supported denture is a type of overdenture that is supported by and attached to implants.
Implant-supported Denture Meaning
A regular denture rests on the gums, and is not supported by implants.
An implant-supported denture is used when a person doesn’t have any teeth in the jaw, but has enough bone in the jaw to support implants. An implant-supported denture has unique attachments that snap onto attachments on the implants.
Implant-supported dentures generally are made for the lower jaw due to the fact that routine dentures tend to be less stable there. Normally, a routine denture made to fit an upper jaw is rather stable by itself and does not need the additional assistance offered by implants. However, you can receive an implant-supported denture in either the upper or lower jaw.
You must get rid of an implant-supported denture day-to-day to clean up the denture and gum area. Simply as with routine dentures, you should not sleep with the implant-supported dentures during the night. Some individuals prefer to have actually repaired (permanent) crown and bridgework in their mouths that cannot be eliminated. Your dental practitioner will consider your specific requirements and preferences when suggesting repaired or detachable choices.
How Does Implant-supported Denture Work?
There are two types of implant-supported dentures: bar-retained and ball-retained. In both cases, the denture will be made of an acrylic base that will appear like gums. Porcelain or acrylic teeth that appear like natural teeth are attached to the base. Both types of dentures need a minimum of two implants for assistance.
Bar-retained dentures– A thin metal bar that follows the curve of your jaw is connected to two to five implants that have actually been placed in your jawbone. Clips or other types of attachments are fitted to the bar, the denture or both. The denture fits over the bar and is securely clipped into place by the attachments.
Ball-retained dentures (stud-attachment dentures)– Each implant in the jawbone holds a metal attachment that fits into another attachment on the denture. Most of the times, the accessories on the implants are ball-shaped (” male” attachments), and they suit sockets (” female” attachments) on the denture. In some cases, the denture holds the male attachments and the implants hold the female ones.
The Implant Process
The implants normally are put in the jawbone at the front of your mouth since there tends to be more bone in the front of the jaw than in the back. This generally holds true even if teeth have been missing for some time. As soon as you lose teeth, you begin to lose bone in the area. Likewise, the front jaw doesn’t have numerous nerves or other structures that could disrupt the positioning of implants.
The time frame to finish the implant depends upon lots of aspects. The quickest time frame has to do with 5 months in the lower jaw and 7 months in the upper jaw. This includes surgical treatments and the positioning of the denture. Nevertheless, the procedure can last a year or more, particularly if you need bone grafting or other initial treatments.
Two surgical treatments normally are needed. The first one places the implants in the jawbone under your gums. The 2nd surgery exposes the tops of the implants. The 2nd procedure comes three to 6 months after the first.
A one-stage procedure is now used sometimes. In this procedure, your dental expert can place the implants and the supporting bar in one step. The success rate of this procedure is high.
Prior to any work is done, you will visit either a dental specialist called a prosthodontist or a basic dental practitioner who has advanced training in the positioning and remediation of implants.
During the test, the dentist will evaluate your medical and dental histories, take X-rays and develop impressions of your teeth and gums so that designs can be made. In some cases, the dental professional might buy a computed tomography (CT) scan of your mouth. This shows where your sinuses (situated above your upper teeth) and nerves are. It enables the dental expert to make sure they will not be impacted by the implant placement. A CT scan also may be done to see how much bone is readily available and to identify the best areas for the implants.
If you are not already wearing a complete denture to replace your missing teeth, your dental professional will make you one. You will use this temporary denture till the implant-supported denture is placed. It will take about 4 check outs, covering a number of weeks, to finish this denture. By making this temporary denture, your dentist has the ability to identify the best position for the teeth in the final denture. The temporary denture likewise can be used as a backup if something happens to the final implant-supported denture. The temporary denture can also be used as the last denture to minimize total expenses. Accessories will need to be included so it can fit firmly to the implants.
As soon as the temporary denture is completed, the cosmetic surgeon will use a copy of it as an overview of assist position the implants in the proper positions. Holes will be drilled in the copy of the denture so that the surgeon can see where the implants must be put.
- Month 1 (if no denture has to be made).
- Month 2 (if denture needs to be made).
The first surgery involves putting the implants in the jawbone. During the first surgery, an incision is made in the gum where the implant will be placed. A hole is drilled in the bone, the implant is positioned into the hole, and the cut is sewn closed.
After this surgery, you need to prevent putting pressure on the implants. The temporary denture can be made so that direct pressure is put on other areas, not on the implants. It may likewise be provided a soft reline (new lining beside your gums) to help to decrease the pressure on your gums.
After the first surgery, the dental professional will wait three or four months if implants were positioned in the lower jaw, and 5 or six months if they were positioned in the upper jaw, before arranging the 2nd surgery. During this time, the bone and the implants integrate (connect and fuse).
- Month 4 or 5 (no denture needed to be made).
- Month 5 or 6 (denture needed to be made).
Once the implants have become fused with the bone, the second surgery can be scheduled. Your dentist will confirm whether the implant is ready for the second surgery by taking an X-ray. This surgery is easier than the first. A little cut is made in your gum to expose the tops (heads) of the implants.
A recovery cap (collar) is put on the head of each implant after it is exposed. This guides the gum tissue to recover properly. The collar is a round piece of metal that holds the gums far from the head of the implant. The collar will be in location for 10 to 2 Week. The dentists will change your temporary denture again and it might be provided another soft reline. The reline material will secure the denture to the healing abutments.
About two weeks after the second surgery, the healing caps will be replaced with routine abutments. Your gums need to now be recovered enough for your dentist to make an impression of your gum tissue and abutments. The impression is used to make a working model of your abutments and jaw. This design is used to make the denture framework and teeth.
Denture Try-In and Insertion
- Month 5 or 6 (no denture needed to be made).
- Month 6 or 7 (denture needed to be made).
At this point, the metal bar is put on the abutments. You will have the first try-in of your brand-new denture structure to see if it fits correctly.
When the metal bar and the denture framework have been meshed correctly, the teeth are temporarily put on the structure in wax. The whole denture is then attempted in your mouth. If everything works well, the teeth are secured in the denture structure completely. The bar or ball accessories also will be protected.
You will need to return to your dental expert for another check out to have the completed denture placed. When the denture is inserted, the denture is clipped onto the bar or snapped onto the ball accessories.
At this moment, your temporary denture will be offered a new reline. This will enable it to be used as a backup denture in case you lose or break your new overdenture. If you are utilizing the “temporary” denture as an irreversible denture, the bar or ball accessories are positioned in that denture.
Caring for Your Implant-Supported Denture
You will have to remove the denture at during the night and for cleaning. You also should carefully clean up around the accessories.
Your dental expert will test all the parts of your brand-new denture to see if they are protected. Despite the fact that your denture is stable, it still can move slightly when you chew. This slight motion can cause the denture to rub versus your gums, which can cause sore spots. Your dental expert will inspect your gums as well as will inspect the method your top and bottom teeth come together (your bite) after insertion of the denture.
The clip or other attachments on the bar-retained denture usually will have to be replaced every 6 to 12 months. They are made from a plastic material (nylon) and will use after continued use.
What Will X-Rays Show?
An X-ray will show the implants in the jaw and any accessories to them. Your dental practitioner will take X-rays a few times during the procedure. They help the dental practitioner to see that the implants, abutments and accessories remain in the right locations.
In addition to the risks of surgery and of the implants stopping working, a bar-retained denture carries certain risks of its own.
A bar-retained denture requires space on the denture framework for the special accessories that are fitted to the bar. This implies that there is less space offered on the denture framework for the teeth to be fitted. Due to the fact that of this, the teeth in some cases can come loose from the base. This issue is easily repaired.
Likewise, when the bar is connected to the implants it is essential that the bar is evenly balanced on each implant. Dentists call this a “passive fit.” If the fit is not passive, the extra strain on the bar can cause the screws to loosen. If you grind or clench your teeth, it’s more likely that parts of the denture will break or that your implants will come loose.
What Can You Expect From Your Implant-Supported Denture?
Your implant-supported denture will be more stable than a regular denture. You will discover it much easier to speak and you won’t need to worry about the denture ending up being loose or falling out of your mouth. You generally will be able to eat foods you could not eat before. Nevertheless, you will not have the ability to chew tough or sticky foods since they can damage the denture.
If you have an implant-supported denture in your upper jaw, it can be made to cover less of your palate (roof of your mouth) than a regular denture. That’s since the implants are holding it in place instead of the suction created between the full denture and your palate.
Denture Try-In and Insertion
- Month 5 or 6 (no denture needed to be made)
- Month 6 or 7 (denture needed to be made)
At this point, the metal bar is placed on the abutments. You will have the first try-in of your new denture framework to see if it fits properly.
