Tooth loss can lead to loss of volume in the facial profile giving an aged appearance.
These implants are longer than usually used in the mouth (about 45-55 mm versus 10-15 mm in conventional ones) and are placed exactly like conventional implants but anchored a little higher, into the Zygomatic bone. It is usually a treatment used with patients who have lost or will lose all the teeth of the upper jaw.
When are zygomatic implants advisable?
- Severe bone resorption of the maxilla.
- In patients who have not had teeth for many years or have suffered aggressive periodontal disease.
- To prevent bone grafts from other donor sites.
Two types of treatments:
- Patient who still has some bone in the front of the maxillary bone:
4 implants are placed in the anterior maxillary area and 2 zygomatic implants in the posterior area.
- Patient suffering total resorption of the maxilla superior:
4 zygomatic implants in the posterior area.
The patient is awake and relaxed during the surgery thanks to the local anesthesia and conscious sedation, with an attending anesthesiologist, without hospitalization needed.
A temporary fixed prosthesis is anchored on the newly placed implants 24 hours after the surgery.
Custom Titanium Mesh
Using a Computerized Tomography (CT) and an intraoral exploration, we build a custom titanium mesh anchored to the patient’s bone, allowing the teeth to be fixed the same day of the surgery.
Also called subperiosteal implants, the mesh is unique and totally tailored to fit the surface of the maxilla/mandible and guarantee a good hold of the micro fixations of 5mm.
This treatment is the best alternative to zygomatic implants when the structure of the maxillary sinus is not intended to be compromised or it is ccupied by infections in the respiratory tract.
It is recommended to avoid long periods of recovery time, as it happens with bone grafts where the bone needs to regenerate before another intervention.
- Safer and less invasive option for patients with severe bone loss.
- Solution with fixed teeth even when the zygomatic bone is diminished.
- Fast treatment as no bone grafts or sinus movements is required.
Custom mesh can be fixed 2 weeks after the CT scan (manufacturing time). Temporary teeth are placed in the same surgery as the custom mesh fixation, so the patient gets a quick solution.
Three months later, once the custom mesh has been properly adjusted, the temporary teeth are replaced by the definitive ones.
In the absence of teeth, the natura root of the tooth is replaced by a short prefabricated titanium implant (8 mm or less).
When are they used?
Short implants are placed regular size implants (10 mm or more) are not advisable due to bone resorption. We can, therefore, avoid grafts and possible complications, mainly damage of sensitive anatomical structures: nerves, sinuses, etc..
- Rapid bone healing as with regular-sized implants.
- It reduces the time and cost of treatment by avoiding bone grafts.
- Surgical technique of low morbidity
Guided bone regeneration treatment is used when the bone available for implant placement is insufficient.
The latter can occur either because it has been a long time since the loss of the teeth or because previous infections in the area have destroyed the bone.
To recover part of the lost bone, we resort to autografts, taking bone from other areas of the mouth, or to xenografts, with collagen membranes that allow bone regeneration.
In these cases, the time required for the treatment is extended by a further 6 months compared to the conventional treatment period.
