Orthognathic surgery is a type of procedure within maxillofacial surgery that is responsible for correcting deformities and abnormalities in the maxillary bones and mandible. Our team of surgeons has performed more than 500 orthognathic surgeries over 15 years. This maxillofacial operation is performed under general anesthesia in a hospital. Next, we present a complete guide on this surgical intervention and its benefits, the price of an orthognathic surgery in Chile and before and after an orthognathic surgery.

Orthognathic surgery is a surgical procedure that is performed to correct dental malocclusions, that is, the incorrect alignment of the teeth and the position of the maxillary and mandibular bones. this surgery maxillofacialIt allows to improve both the functionality and the facial aesthetics of the patient.

An orthognathic surgery is the treatment for a class II or a class III. They usually call themorthognathic class 2ororthognathic class 3

Classification of anomalies

Before carrying out orthognathic surgery, the patient must be evaluated by a multidisciplinary team made up of a maxillofacial surgeon, an orthodontist and an anesthesiologist. The evaluation includes:

  • Anamnesis and clinical examination.

  • Analysis of dental models and radiographs.

  • Orthodontic treatment planning before and after surgery.

Evaluation process prior to surgery

Orthognathic surgery is indicated for those patients who present:

  1. Dental malocclusions: when the upper and lower teeth do not fit properly when closing the mouth.

  2. Skeletal deformities: such as prognathism (prominent jaw), retrognathism (retracted jaw) or facial asymmetry.

  3. Functional problems: Difficulties chewing, speaking or breathing due to the position of the jawbones and jaw.

The goals of orthognathic surgery include:

  • Correct dental malocclusion and improve occlusion.

  • Improve the facial aesthetics of the patient.

  • Solve functional problems, such as chewing and phonation.

Indications and objectives of orthognathic surgery: 

After orthognathic surgery, it is normal to experience some swelling and discomfort in the operated area. The maxillofacial surgeon will provide detailed instructions on postoperative care, including:

  • Use of analgesic and anti-inflammatory drugs.

  • Liquid or soft diet for the first few weeks.

  • Oral hygiene care with rinsing and soft brushing.

  • Avoid intense physical activities and sun exposure.

  • Go to regular reviews with the surgeon and orthodontist.

  • Oral hygiene care with rinsing and soft brushing.

Types of orthognathic surgery

The types of orthognathic surgery are many:

  • Maxilla

  • Jaw

  • Condyles and asymmetries

  • Mentoplasties

  • Combined surgeries

Another way to classify them is according to the diagnosis:

  • Class II surgeries: those performed for patients with small jaws, many times with apnea.

  • Class III surgeries: those performed for patients with prominent jaws, undershot jaws, prognathisms, or large jaws

Class II orthognathic surgery

Class II is a type of malocclusion that generally involves an excess projection of the upper jaw relative to the lower jaw, known as an overbite. This condition can be associated with problems with sleep apnea and bruxism, due to the position of the jaw and the misalignment of the teeth. In some cases, orthognathic surgery may be necessary to correct the overbite and improve respiratory function and overall oral health. The surgery involves an advancement of the upper jaw to align it with the lower jaw and improve dental alignment.

Class III orthognathic surgery

Class III is another type of malocclusion that involves excessive protrusion of the lower jaw relative to the upper jaw, known as mandibular prognathism. This condition can also be associated with sleep apnea and bruxism problems, as well as a sunken facial appearance and crossbite. In some cases, orthognathic surgery may be necessary to correct jaw prognathism and improve dental and facial alignment. The surgery involves a setback of the lower jaw to align it with the upper jaw and improve facial aesthetics and masticatory function.

Before and after orthognathic surgery

Orthognathic and orthodontic surgery

Orthognathic surgery is usually accompanied by orthodontic treatment before and after the intervention. The objective of orthodontic treatment is to align the teeth and prepare the maxillary and mandible bones for surgery, as well as to maintain the results obtained after the maxillofacial operation..

In general, orthodontic treatment prior to surgery lasts between 12 and 18 months, while orthodontic treatment after surgery can last from 6 to 12 months.

We operate in different clinics, currently most of the surgeries are performed in clíncia redsalud Providencia ex avansalud.

Then there is a slow recovery that can last months.
  • What is the modern technology available for this treatment?
    Simplant OMS, Nemoceph 3d and Dolphin Imaging 3d are the main tools available in Europe and the United States: With these systems we carry out a detailed diagnosis, three-dimensional treatment planning and the preparation of all the necessary guides for the moment of the operation Dolphin Imaging 3d is the most powerful tool available in the world, it is used in implantology to plan complex surgeries and in Maxillofacial Surgery to plan and predict the results of our surgeries. It is within the reach of our patients, we have 8 years of experience and close to 200 cases operated and planned digitally. Within reach of our patients. With a dental maxillofacial tomography, the complete image of our patient is acquired. In Chile, radiological centers have the necessary equipment and the exams have similar values to conventional studies. Then, with the CD loaded with the tomography, we process the image and plan our surgery. We evaluate the case, perform the surgery and obtain the 3d printed guides. We have four 3d printers and two intraoral scanners to register the dental models of our patients. that way we can register and transfer an exact copy of the patient to his mouth.
