Zygomatic implants: an alternative when there is a lack of maxilla bone

Zygomatic implants were introduced by Branemark in 1988 and have been designed to restore the superior maxilla in those patients that have important lack of bone. Their use had made possible to reduce the procedures of bony graft, and have become in such a good alternative in patients with a really weak superior maxilla where the minimum chirurgical procedure and the less time as possible.

In these patients, the collocation of implants for the oral rehabilitation is very limited, because of the quantity and also because of the quality of the bone, especially when the maxillary sinus is filled with high quantities of air.

In these cases when pre-prosthetic is required, by means of the realization of bone grafts or procedures such as the elevation of the maxillary sinus. In many occasions, the patients reject these treatments because of the numerous numbers of surgeries and because of the time of healing that the tissues require.

Zygomatic implants are an alternative way to those procedures, reducing the number of surgeries needed and reducing the time of oral rehabilitation. The Zygomatic implants offer very good results due to the fact that are placed in a zone where sufficient bone exists, such as cheekbone, and moreover are larger implants than the conventional implants what gives a greater union zone with the bone, remaining in a wider zone where the bone, being anchorage strongly, making possible the placement of the dentition 24 hours after the surgery. It could be combined with conventional implants if the bones atrophy is moderate, however, when there is lack of bone is total there could be placed two zygomatic implants on each side, what allows the rehabilitation of the patient completely. The required surgery for these treatments is done with conscious sedation and hospitalization is not needed.
