Planning of orthognathic surgery through the primary mandibular reconstruction according to the postnik protocol

Orthognathic surgery is understood as a group of surgical procedures intended to achieve correct position and relation of the maxillaries, and the rest of the cranium and the cervical unit. It requires great analysis and previous work.

According to the conventional planning of the orthognathic surgery, it is very important to achieve correct positioning of the superior maxillary, fundamental factor of the nasal-labial-dental position and of the profile. The classic technique starts with surgery, placing the superior maxillary into position.

A fundamental part in carrying out the Maxillary Repositioning Le Fort Osteotomy is having the correct maxillary hinge axis; the splint that goes above the jaw allows me to take the maxillary to the desired position.

Many patients do not have mandibular stability, for example, those who suffer hemifacial microsomia. In order to solve the maxillary positioning problem without a stable jaw it is suggested that the procedure start with jaw surgery in primary form, and based on this new, stable mandibular position, the maxillary can be placed correctly.

Postnik does this without giving up the philosophy of the importance of the maxillary position and the lip tooth relationship, and in order to do so in model surgery, the double assembly of the superior model technique is implemented.

In this report this technique will be analyzed, along with the clinical cases of four patients, their results, and their stability through time.
