Zygomatic implants are a technique for the rehabilitation of the atrophic maxilla , that is, the maxilla in which there is very little bone, with insufficient height or width. They are an excellent alternative in the treatment of edentulous patients.
Possible causes of atrophy of the maxillary bone
Edentulous bone that does not receive a charge signal (through the tooth or implant), is reabsorbed continuously over time.
Long -standing edentulism , the use of dentures , complex tooth extractions and periodontitis (a disease of the gums) can cause this loss of the maxillary bone.
Periodontitis leads to the loss of the gum and the supporting bone of the teeth, which therefore move to fall and generate this maxillary atrophy.
On the other hand, removable dentures traumatize the bone, which also does not work and ends up disappearing.
Difference with conventional implants
Unlike conventional implants, zygomatic implants are longer and more robust, to be anchored in the malar bone (zygomatic). As this is a very hard and cortical bone, the placement of bone grafts from other parts of the body is not necessary.
This surgery is performed in the operating room, either under sedation or general anesthesia. Of course, they must be performed by a maxillofacial surgeon.
Advantages of zygomatic implants
The main advantage of zygomatic implants is that we obviate graft surgeries, and the treatment time is radically shortened. In case of absence of maxillary bone, we place the zygomatic implants and, after about a week, the crowns can be fixed in them to recover the chewing and aesthetic function of the lost teeth.
All this results in comfort for the patient , because we save surgeries and shorten the time, even in the postoperative period. In turn, we save the economic expense that is derived from all these procedures.
