ORTHOGNATHIC SURGERY

 
 

DEPARTMENT OF ORTHOGNATHIC SURGERY

 
The Orthognathic Surgery Department is dedicated to the diagnosis and surgical treatment of changes in adult facial bone development.

Orthognathic surgery is an intervention that corrects dentofacial asymmetries in order to achieve a perfect balance of the face and teeth. Dentofacial dysmorphias are quite common in the general population.
 
 
 

THE ORTHOGNATHIC SURGERY

 
 
 
 
 
 
 
 
Orthognathic surgery is an intervention that corrects dentofacial asymmetries in order to achieve a perfect balance of the face and teeth.

After a variable period of orthodontic treatment, the intervention is performed on the jaws to achieve a perfect balance between all the patient's facial features, correct occlusion and improve breathing (boosting greater air passage through the upper airway).

As we change the position of the jaws forward, backward, upward or downward, the soft facial tissues also move with them, that is, the chin, lips, cheeks and the tip of the nose, the height of the face changes accordingly. Thus, once the jaw is placed in a correct position, the facial profile becomes correct and produces harmonious new facial features.

Orthognathic surgery is closely related to orthodontics. Normally, treatment begins with wisdom tooth extraction, followed by orthodontic treatment prior to surgery that lasts between 1 and 2 years, in collaboration with the orthodontist. This time may be shorter, depending on the case. Therefore, the correction of dentomaxillofacial deformities always involves teamwork between the orthodontist and the surgeon.

 
 
 
 
 

DENTOFACIAL DEFORMITY

 
Dentofacial dysmorphias are quite common in the general population. Usually, people find that they have difficulty in chewing because their teeth do not fit well or because they notice a change in the size of their chin which negatively influences their self-esteem. The problems where this procedure is indicated are:

  • Mandibular prognathism or "big chin"
  • Retrognathism or "small chin"
  • Gingival smile or "gummy smile"
  • Open bite or "front upper and lower teeth that slant outwards"
  • Cross bites and facial asymmetry or "crooked or deviated face"

These bone changes result in an incorrect position of the teeth, with a negative impact on facial harmony/aesthetics. These can be treated in isolation or associating various aspects, creating an individualized treatment plan to obtain the best functional and aesthetic result in each case of orthognathic surgery.

Treatment with orthognathic surgery is a procedure that always includes associated orthodontic treatment before and after surgery. After orthognathic surgery, intensive rehabilitation treatment is always necessary.

Changes in the length, width or height of the jaw result in difficulty in accommodating the teeth as well as changes in the relationship between the upper and lower teeth. The teeth try to adapt to this lack or excess of bone, adopting positions different from those they would have if the structure were correct. Excessive showing of the gums when smiling, inability to completely bring the lips together effortlessly, not showing the upper teeth when smiling, jaw back, jaw forward, crooked teeth in the jaw, facial asymmetries, chin back, chin forward, are some of the main complaints of our patients. These problems, being of the jaws and teeth, must be treated together with Orthodontics (to decompensate the adopted position) and surgery (to put the jaws in the correct position), otherwise this could give to unsatisfactory final results, indefinite and recurrent orthodontic treatments, with patients often experiencing asymmetries on the face, for example, a deviated chin with important aesthetic implications.
