Orthognathic Surgery Singapore

What Is Orthognathic Surgery?

Orthognathic surgery, also known as corrective jaw surgery, is a surgical procedure performed to correct irregularities or misalignment of the jaws and teeth. It involves repositioning the upper jaw, lower jaw, or both, to achieve proper alignment and balance between the jaws, improve facial aesthetics, and enhance the functionality of the bite.

What Is Orthognathic Surgery

Why Orthognathic Surgery Is Necessary

Orthognathic Surgery - Why Is It Necessary?

Orthognathic surgery is necessary in certain cases to correct significant jaw irregularities and misalignment that cannot be effectively addressed through orthodontic treatment alone. These irregularities can affect both the aesthetic appearance of the face and the functionality of the jaws, teeth, and bite.

Correcting Bite Problems

Orthognathic surgery is often performed to address severe overbites, underbites, open bites, or crossbites that result from skeletal discrepancies between the upper and lower jaws. These bite problems can cause difficulty in chewing, speaking, and even breathing.

Improving Facial Aesthetics

Jaw irregularities can impact the facial profile, causing an unbalanced or asymmetrical appearance. Orthognathic surgery can reposition the jaws to enhance facial harmony, balance the proportions of the face, and improve overall facial aesthetics.

Alleviating Temporomandibular Joint (TMJ) Disorders

TMJ disorders can occur when the jaw joints are not properly aligned, leading to pain, discomfort, and limited jaw movement. Orthognathic surgery can help correct the underlying skeletal issues, providing relief from symptoms and improving jaw function.

Resolving Sleep Apnea And Breathing Difficulties

In some cases, orthognathic surgery may be recommended to address obstructive sleep apnea, a condition characterized by repeated pauses in breathing during sleep. Surgery can help reopen the airway by repositioning the jaws and improving the alignment of the upper airway structures.

Orthognathic Surgery - When Do You Need It?

Orthognathic surgery is typically recommended for individuals who have jaw discrepancies that cannot be corrected through orthodontic treatment alone. These jaw irregularities may include an overbite, underbite, open bite, crossbite, or a combination of these conditions. The surgery aims to improve the overall harmony and balance of the facial structures, enhance chewing and speech function, alleviate breathing problems, and address related issues such as temporomandibular joint (TMJ) disorders or sleep apnea.

Orthognathic Surgery - The Diagnosis

The diagnosis of orthognathic surgery involves a comprehensive assessment and evaluation of the patient's jaw and facial structure, dental occlusion (how the teeth fit together), and related factors. In addition to assessment and evaluation, the diagnostic process typically includes the following steps:

Radiographic Imaging

the jaws, teeth, and facial structures. These images provide valuable information about the underlying skeletal relationships, the position of the teeth, and any abnormalities or irregularities that may require correction.

Three-Dimensional Imaging

Advanced imaging techniques, such as Cone-Beam Computed Tomography (CBCT) scans or Computerized Tomography (CT) scans, can provide three-dimensional images of the jaws and facial structures. These images allow for a more detailed analysis of the skeletal relationships and aid in surgical planning.

Orthodontic Evaluation

You will be referred to an orthodontist who specializes in the alignment of the teeth and bite for joint assessment. The orthodontist will evaluate the dental occlusion, identify any orthodontic issues, and determine the need for orthodontic treatment before and after orthognathic surgery.

Orthognathic Surgery - Potential Risk Factors

Orthognathic surgery, like any surgical procedure, carries certain risks and potential complications. It is essential to be aware of these risk factors before undergoing the surgery. Some potential risk factors associated with orthognathic surgery include:

  • Infection
  • Bleeding
  • Nerve damage
  • Relapse
  • Changes in bite or occlusion
  • Difficulty with jaw movement or function temporarily

Orthognathic Surgical Procedure & Treatment

The procedure will be performed by our oral and maxillofacial surgeon, Dr Ng, in collaboration with an orthodontist. Prior to the surgery, a comprehensive evaluation is conducted.

Initial Consultation

We will review your medical and dental history, including any previous orthodontic treatments. We will also discuss your concerns, symptoms, and desired outcomes.

Physical Examination

We will perform a physical examination of the face, jaws, teeth, and temporomandibular joints (TMJs). We will also assess the facial profile, jaw alignment, bite relationship, and any visible asymmetries or irregularities. Measurements, X-rays, photographs, and possibly 3D imaging scans may be taken to aid in the diagnosis.

Orthodontic Evaluation

You will be referred to an orthodontist who will assess the alignment of the teeth and how they fit together. The orthodontist will evaluate the presence of malocclusion (misalignment of the teeth) and determine if orthodontic treatment is necessary prior to or in conjunction with orthognathic surgery.

Models And Impressions

Dental impressions or scans may be taken to create models of the teeth and jaws. These models allow us to study the current occlusion, simulate the planned surgical movements, and plan the orthodontic treatment required before and after surgery.

 

Treatment Planning

Based on the comprehensive evaluation and diagnostic findings, we will develop a personalized treatment plan. This plan outlines the recommended surgical procedures, anticipated jaw movements, estimated duration of treatment, and expected outcomes.
