A full-arch implant prosthesis replaces all missing teeth in a jaw. It is supported by dental implants, which are artificial titanium roots inserted into the jawbone. Unlike removable dentures, this solution is fixed, thus offering more stable and comfortable retention.
Opting for an implant prosthesis offers several advantages. It improves quality of life by facilitating chewing and stabilizing the prosthesis. You will no longer need denture adhesive to secure your teeth. Furthermore, this treatment limits bone loss, which is common with traditional dentures, and helps preserve the natural contours of the face. Finally, this option is more aesthetic and provides a sensation of natural teeth.
A 3D cone beam radiograph assesses bone volume and critical structures to plan the placement of implants (4 or 6) for full-arch rehabilitation, optimizing the stability of the future implant-supported bridge.
Depending on the bone anatomy, 4 or 6 implants (straight anterior, angled posterior) are placed to stabilize the fixed prosthesis without bone grafting. This configuration provides a solid base for the full bridge.
An optical impression is taken after surgery with an intraoral scanner to precisely capture the implant positions. A temporary resin prosthesis is placed within 24 hours for immediate comfort.
After 3 to 6 months, a definitive zirconia ceramic prosthesis, manufactured in France, is placed for optimal aesthetics and durability. Designed by CAD/CAM, it is screw-retained to ensure maximum stability.
Regular check-ups (biannual or annual) are performed to monitor osseointegration and ensure optimal hygiene. The zirconia bridge facilitates maintenance and ensures the longevity of the rehabilitation.
The placement of an implant prosthesis is recommended when all teeth in a jaw are missing or need to be removed. It is feasible if you have lost your teeth due to cavities, trauma, or periodontal disease. This treatment is particularly suitable if you are looking for a fixed solution that is more comfortable than conventional removable dentures.
To consider this option, it is essential to check the condition of your jaw. If the bone quality is sufficient to accommodate the implants, the procedure can be performed. If bone resorption has occurred, bone grafting may be considered before implant placement.
This technique uses four dental implants to support a fixed prosthesis. Two implants are placed vertically at the front of the jaw, and two others are placed at the back, often angled to maximize the use of available bone.
As its name suggests, this technique uses six implants to support a fixed prosthesis. The implantation is done similarly, but with two additional implants for greater stability.
There are contraindications to the placement of an implant prosthesis. If you suffer from uncontrolled chronic diseases such as diabetes, the risks of complications increase. Smokers are also more prone to implant failures, as bone healing is slower.
Heavy medical treatments, such as radiotherapy in the head and neck region, can also compromise the success of implantation. If you have coagulation problems or bone pathologies, the decision must be made with caution. Finally, poor oral hygiene and an inability to maintain regular care can make this solution unsuitable.
Before placing an implant prosthesis, precise examinations must be carried out. A general health check is necessary to ensure the absence of contraindications. A CT scan or panoramic radiograph allows evaluation of bone density and determination of the position of anatomical structures to avoid, such as nerves.
A complete oral examination must also be performed to assess gum health and identify any infections. These examinations allow the practitioner to decide on the number of implants needed and their precise placement.
Care for implant prosthesis placement begins with a detailed consultation. You will be informed of the different steps and the cost of the treatment. If you are eligible, a personalized treatment plan will be developed, taking into account your needs and the examination results.
The dental surgeon will then plan the procedure. They may prescribe medication to prepare your mouth and reduce the risk of infection.
Before the procedure, be sure to follow preoperative recommendations. Avoid smoking and take prescribed medications to prevent infections. On the day of placement, the procedure is performed under local anesthesia or light sedation.
During the procedure, implants are inserted into the jawbone. The number of implants may vary, but it is often necessary to place four to six to ensure good stability of the prosthesis. A healing period, called osseointegration, is necessary for the implants to fuse with the bone.
A temporary prosthesis may be fixed during this phase so that you can continue to chew and speak normally. The duration of osseointegration varies, but it generally takes between three and six months. Once this period has elapsed, the definitive prosthesis is installed. It is custom-designed to fit your mouth perfectly.
After implant prosthesis placement, regular follow-up is essential to ensure the success of the treatment. In the first few weeks after the procedure, it is crucial to follow your dentist’s recommendations. Avoid eating hard foods during the first few days to allow the implants to stabilize properly.
Regular check-ups every six months are necessary to ensure that the implants and prosthesis are in good condition. During these visits, the dentist will check the stability of the implants, the condition of your gums, and perform a professional cleaning if necessary.
If you experience persistent pain, prosthesis mobility, or gum inflammation, contact your dentist immediately.
