Slide Implants for patients with bone loss

Lack of teeth can lead
to the loss of the lower jaw

Zygomatic Implants

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, in the Zygomatic bone. It is usually a treatment that is used in patients who have lost or will lose all the teeth of the upper jaw.

When is it advisable to use zygomatic implants?

  • Severe bone resorption of the maxilla.
  • In patients who have not had teeth for many years.
  • Patients who have suffered aggressive periodontal disease.
  • To prevent bone grafts from other donor sites.
  • When recovery and treatment time is important.

There are two types of treatments:

  1. 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.
  2. Patient suffering total resorption of the maxilla superior: 4 zygomatic implants in the posterior area.

This intervention is done with local anesthesia and conscious sedation, with an attending anesthesiologist. The patient is awake and relaxed. A temporary fixed prosthesis is always anchored on the newly placed implants within 24 hours of surgery.

Short Implants

What are they? As we have said before, an implant is a prefabricated titanium root, which is placed in the place where there is absence of teeth. It replaces the natural root of the tooth. We consider short implants to those equal to or less than 8 mm.

When are they used? We consider short implants to be those equal to or less than 8mm. We place them in areas where there is a lack of bone. Its use is conditioned to the anatomy of the patient, when due to bone resorption, we cannot place implants of a regular size (10 mm or more). We can, therefore, avoid grafts and possible complications, mainly damage of sensitive anatomical structures (nerves, sinuses, etc. …).

Advantages:

  • Surgical technique of low morbidity
  • Rapid bone healing as with regular-sized implants.
  • It reduces the time and cost of treatment by avoiding bone grafts.

Bone graft

In some cases, the bone available for implant placement is insufficienteither because it has been a long time since the loss of the teeth or because previous infections in the area have destroyed the bone. In such cases we resort to guided bone regeneration. To do this we resort to xeno grafts with collagen membranes that act as a barrier to allow bone regeneration, or to autografts, taking bone from other areas of the mouth. In this way you can recover part of the lost bone to allow the placement of dental implants.

In these cases the time required for the treatment is extended by a further 6 months compared to the conventional treatment period.
