An Implant-Supported Dentures Overview
An implant-supported denture is a kind of overdenture that is sustained with and connected to the implants.
The arrangement can be comprehended this way- dentures are worked with implants to provide the perfectly fitted appliance that lasts longer.
Traditionally, implants are applied when there are no teeth left in the jaw but otherwise, have sufficient bone to sustain implants. On the other hand, conventional dentures are supported by gums and do not demand implants.
However, implant supported dentures employ special attachments that can be placed onto the implant attachments.
Notably, implant supported dentures are more or less utilized for the lower jaw, providing stability to the denture (as many times conventional dentures feel unsteady in the lower jaw region).
However, there is no fixed pattern for getting particular dentures for upper or lower jaw and you can receive implant supported dentures in the upper jaw as well.
Types of Implant Supported Dentures
Conventionally, there are two kinds of implant supported dentures- Bar retained and ball-retained.
- Both these dentures are construed with the acrylic base and made to resemble gums.
- Both these dentures are fabricated with teeth made from porcelain or acrylic and made identical to natural teeth.
- Both types of implant supported dentures require the support of minimum two implants.

- Following the curve of your jaw, a thin metal bar is placed.
- This metal bar is attached to two to five implants in the patient’s jawbone
- The bar, the denture or both are fitted with clips or other sorts of attachments.
- The denture is placed over the bar and is securely clipped into the place with the help of the attachments.

It further enables dentists to identify if the sinuses or nerves are not harmed by the implant placement. A CT scan moreover helps in determining how much bone is left and ascertain best locations for the implants.
Positioning your Denture Implants
The front of your jawbone has more bone than the back area. The implants are deposited in the front of the mouth for the same reason. More than often this happens as the teeth’s are missing for a greater period of time.
In addition, the front jaw does not hold any nerves or any such structures which should possibly interfere with the position of the implants.
Determining the Time Period
There could be a number of factors that could determine the time period to complete the denture implant process. On average the minimum time frame suggested is 5 months for lower jaw and seven months for the upper jaw.

Aftercare: The aftercare involves avoiding pressure on the implants. The dentist may give you temporary denture so that direct pressure is evaded on the implants. Temporary dentures give soft reline, a new lining subsequent to your gums) to support you and abate the pressure on your gums.
After completing a successful first surgery, the dentist will ask you to pause for three to four months if implants were fitted for the lower jaw. While the average waiting time for upper jaw is five or six months before scheduling the second surgery. Throughout this time, the bone and the implants blend and fuse together.
Depending on the requirement of dentures, the dentist will wait for 4 or 5 months if you don’t need to make a new one or 5/6 months for the vice versa.
Procedure: The second surgery is scheduled at once if the implants seem to have been fused properly. The dentist approves for the surgery after taking an X-ray, which reports if the implant is fit for the surgery or not.
- The second surgery is modest than the first one and requires a small incision in your gums. This reveals the roofs of the implants, where a healing cap or collar is also placed on each.
- The collar is a rounded piece of metal that checks the gums are away from the head of the implant and helps your gum tissues to heal correctly.
- The standard waiting time for sustaining with a collar is 10 to 14 days. Now again the dentists will fit your temporary denture for another soft reline. The reline substance will fasten the denture to the healing abutments.
- Two weeks after the second surgery, the healing caps are substituted by regular abutments. The dentists make sure that your gums are healed suitably to making an impression of your gum tissue and abutments.
- These impressions are then used to make the model of your abutments and jaw. Further, it makes the denture framework and teeth.

The next waiting time is 5 or 6 months if no dentures need to be made. Further, if you require dentures then it will be- 6 or 7 months.

Nonetheless, you may have to pay another visit to your dentist for insertions. During insertion of the denture, it is snipped onto the bar or closed on the balls for attachments.
