Zygomatic implants are implants designed to replace the lost tooth or teeth with a good anchorage to the bone, allowing us to create one or several multiple teeth to replace the aesthetics and functionality of our patients simultaneously with the extraction of the teeth.
It is necessary to differentiate between the immediate implant (which is placed at the same time as the extraction of the tooth) and immediate loading on implants, which consists of placing the teeth immediately after the insertion of the implants in the mouth without the need to wait for the time of integration of the implant in the bone.
Immediate load implants technique
The technique consists of extracting one or more teeth and, in the same act, replacing the lost roots by means of implants in order to build the lost teeth on them. In this way the tissues are preserved and the esthetics and functionality of the patient are preserved.
If the conditions are appropriate (basically good retention and anchorage of the implant in the bone), the tooth can also be placed at that moment, that is, immediate loading.
The time of the process depends on the number of teeth to rehabilitate and the technique used by the dentist. If we are going to rehabilitate one or several teeth, we can have the patient rehabilitated in less than an hour. On the other hand, if we are going to rehabilitate complete jaws, we will use digital impression techniques, in which the laboratory makes prostheses designed to measure for our patients, and they can be placed in the mouth in less than 24 hours.
The loading order for the definitive prosthesis will depend on the type of implant to be used; there are special implants that allow loading in a month and a half, and traditional implants in 3 or 4-6 months.
Advantages and disadvantages of immediate loading
The main advantage of immediate loading implants is immediate esthetics and preservation of peri-implant tissues. On the other hand, the main disadvantage is the risk of early implant loss due to excessive loading, but this is easily solvable.
In any case, the success rates are similar to those of deferred (conventional) implants.
