While a single tooth can be replaced with a removable appliance, the looks, function and convenience of a “permanent” replacement are far superior. In the past this could only be accomplished with a bridge, where the teeth on either side of the missing tooth are crowned, with the replacement tooth connected to the crowns.
This is an excellent restoration, but many people would prefer not to have to “prepare” or cut down, the adjacent teeth. Today, dental implants have become so predictable they are now the standard of care to replace single missing teeth instead of a bridge.
The advantages of implants over bridges include:
● It is not necessary to drill down the adjacent natural teeth to make crowns
● The teeth remain separate, making cleaning and flossing easier
● If a bridge fails, the entire bridge must be removed, Implants are stand-alone
Multiple tooth implants are used to replace several teeth that are missing. This can be done by either placing implants side-by-side or by placing implants at each end of a gap and placing a crown and bridge restoration on top. Once placed, a multiple tooth implant will feel and perform like natural teeth.
Full arch implants are used to replace an entire upper or lower arch of teeth. This is done by strategically placing implants along the upper or lower jaw and attaching a denture-like attachment over abutments on the implant posts. Once placed, a full arch of teeth using the implants as support will feel and perform like natural teeth.
The advantages of implant supported removable appliance include:
● More secure retention and fit of appliance, improving function and comfort
● Less stress on any remaining natural teeth holding the appliance
● Reduction or elimination of bone shrinkage where implants placed
● Eliminated the need to “cut down” the neighboring teeth to make a bridge
● Maintains the jawbone structure
● Feels and functions like natural teeth
● Does not rely on other teeth for support
● Replaces partial plates and may be used to secure loose dentures
● Cleaned and flossed like a natural tooth
There are actually two phases to implant dentistry.
Phase 1: Using very accurate surgical techniques, an incision is made in the gum tissues and implants are placed into dimensionally controlled sites (depth and width) in the jawbone. First, the gum tissue is opened and the jaw bone is tapped with a small drill and then drilled with a wider drill. The implant is inserted into place. The gum tissues are then closed and the healing phase begins. This may take anywhere from 3-6 months to ensure a strong foundation to support a tooth.
Phase 2: An abutment is secured o the top of the implant. Finally, the restorative dentist will place a new crown onto the implant abutment. Implants can replace a single tooth, several teeth or secure your dentures.
As an alternative to wearing a full denture (if there is adequate bone or bone augmentation procedures can be performed to grow sufficient bone)
multiple implants can be placed across the jawbone to provide support for a fixed bridge. This procedure is similar to those described for single
or multiple implants but requires careful diagnosis, planning and coordination before treatment begins. This attention to detail will ensure that
an appropriate number of implants can safely be placed in positions that will allow your dentist to fabricate a bridge which will meet your needs
The number of implants necessary for a full-arch fixed bridge varies depending on your particular anatomy, the opposing teeth, the type of bridge you want to have placed and the number of teeth you want or need to replace with the prosthesis. A full arch of implants can be placed when you are already missing all teeth in one of your jaws. If you have teeth remaining, they may need to be removed as a first step before implant surgery can proceed, or sometimes the teeth may be extracted and implants placed immediately after the teeth have been removed. If there are teeth remaining, you may be able to have a temporary fixed-bridge made by your dentist to help transition from your own teeth to implants. In this scenario (while the implants are healing), the temporary bridge stays in place which allows chewing, speaking and smiling - all without having to wear a removable denture. If it is not possible to retain enough teeth to support a fixed bridge while the implants are healing, then you may need to wear a removable denture temporarily.
Usually, you will be advised by your dentist to refrain from wearing the denture for a period of time (customarily two weeks) after the implants have been placed. This allows the gums to heal without being disturbed. In recent years, we have learned that it is often possible to place a full arch of implants and connect them to a fixed bridge (usually temporary) in what is known as immediate loading - which means the implants are receiving “load” from chewing forces as soon as they are placed.
This newer procedure is highly successful but there are certain requirements for its success. This technique requires careful planning and coordination by your dentist and surgeon and as with all treatment, you should discuss all of your options and alternatives with your dentist and decide together which may be the best and most appropriate for you.
An implant overdenture fits over a dental implant with various types of attachments that provide you with excellent stability and retention
of your complete dentures. The implant overdenture is a full denture used to replace the teeth in a full-arch where all the teeth are missing.
In essence, it is a larger version of the implant assisted removable partial denture (IRPD). The denture can "snap" into place to afford you
more comfort, and improved chewing ability. Implant overdentures are held in place by various dental attachments selected by your restorative
doctor to provide maximum retention, and increased chewing ability. The implant overdenture is removable to facilitate cleaning of the implant
supporting structure. Implant overdentures can be made to look extremely natural and feel comfortable.
Pre-surgical prosthodontic planning for implant overdentures begins with diagnostic impressions for recording jaw relation and diagnosing possible dentures. These impressions help to determine the correct positioning of the teeth on the new dentures as well as to confirm the optimal location for each implant. They are also used to assure correct appearance and bite. Frequently, a template is produced from the diagnostic impression that is provided to the surgeon for guidance during implant placement surgery.
Most often, an upper overdenture will require placement of more implants than a lower overdenture due to the different nature of the anatomy of the upper and lower jaws. It may also be possible to fabricate an upper denture without a palate (roof of the mouth), which may be a more comfortable option for some patients.
The specific need for an implant overdenture can vary and the decision for this treatment option should be made with your restorative dentist. Many patients can benefit from the facial support provided by the extensions of the complete denture design. The number and type of implants should be decided upon following a detailed discussion between you and your dentist(s), a thorough examination, and careful consideration of your personal experiences with your current dentures.
