Overdentures are replacement teeth retained by dental implants. A denture supported by implant is a type of over denture that attached and supported to the jaw bones. Overdentures dental implants are a long term solution for stabilizing dentures.
Need for Implant Overdentures:
- It promotes better digestion and Poor fitting dentures are often held in by using adhesives.
- Overdentures utilize dental implants, so they are more stable than adhesives.
Treatment & Procedure of Implant Overdentures:
Placement of two conventional dental implants in the lower anterior (front/chin) jaw, and attaching solitary anchor systems (ball-abutments). Consequently, bone continues to melt away over time behind the implants. As bone melts away, the overdenture procedure will no longer adapt/fit the tissues.
A brief explanation of the stages involved in placing implant-supported dentures.
The Initial Consultation
At your initial exam, you will see a prosthodontist or a dentist experienced in implant placement. Impressions and x-rays are taken so that models can be created. Some dentists also order a CT scan to locate your sinus cavities and nerves, and determine how much bone is available. Over the next few visits, a temporary denture will be made for you.
The First Surgery
During your first surgery, implants will be placed into your jawbone. After making a small incision, your dentist will drill a hole in the exposed bone, place an implant, and close the incision with stitches. The process is repeated for each implant. You’ll be required to wait three to six months before you can have the second surgery; this period of time allows the implants to fuse to your jawbone.
The Second Surgery
The second surgery exposes the tops of your implants. Once exposed, a healing cap or collar is placed on each head to help guide healing. You’ll need to wear the collar for 10 to 14 days. Next, healing caps are replaced with regular abutments. Your dentist will make another impression to help create your denture framework and artificial teeth.
Insertion: The Final Step
Finally, a metal bar is placed on the abutments, and you will try on your denture framework and artificial teeth. If everything fits, your new teeth are permanently secured in place, and bar or ball attachments are added to keep the frame fastened to your implants. Your dentist will show you how to care for your new implant-supported dentures, and schedule follow-up appointments to check your oral health.
