CORRECTING YOUR JAW ALIGNMENT (Understanding Orthognathic Surgery In Singapore)

Orthognathic Surgery

Orthognathic also known as corrective jaw surgery in Singapore is an oral and maxillofacial surgery. It comprises a joint orthodontic and surgical approach in aligning dental and jaw disharmonies. 

What is Orthognathic Surgery?


What is Orthognathic Surgery?

Orthognathic surgery also known as corrective jaw surgery, is performed to improve your jaw functionally and aesthetically.


You may need this surgery if one or both of your jaws are in disharmony, for example, having your upper teeth too far forwards or too far backwards.

Benefits of Orthognathic Surgery

For patients with jaw disharmony, orthognathic surgery offers numerous benefits including: 

Enhance Bite Alignment

Realigning your jaws would correct the way your jaws come together, resolving issues of an open bite, where the upper set of teeth and lower set of teeth do not touch. 

Enhanced Eating Ability

With an aligned bite, the ability to chew and eat is now enhanced.  

Enhanced Speaking Ability

With an aligned bite, the ability enunciate and pronounce words is now enhanced, improving speech ability. 

Enhanced Quality of Life

Patients will notice enhanced breathing ability, sleep patterns and sleep quality. 


It has the potential to resolve temporomandibular joint (TMJ) disorders and other jaw problems, relieving pain.


It may also work as a solution to resolve obstructive sleep apnea, allowing for non-interrupted sleep, and for you to feel rested during the day. 

Enhanced Aesthetic Look

Jaw surgeries correct issues of underbites, overbites and crossbites, giving you an enhanced smile and facial appearance.


This may boost your confidence, allowing you to feel good in your own skin. 

Do I Need Orthognathic Surgery?

You may need orthognathic surgery if your jaws are in disharmony. This disharmony can be indicated if:
  • You have severely crooked teeth;
  • You have an increased risk of many dental diseases (e.g. gum disease, tooth wear and tooth fracture, etc.) and dental abnormalities;
  • You may experience severe consequences on your dental and facial tissues if there is a physical trauma on the jawbones or have a jaw deformity;
  • You have difficulty chewing, speaking or sleeping due to breathing abnormalities;
  • The aesthetics of your face compromised (for example through excessive exposure of your gums, facial asymmetry and elongation of your face);
  • You are experiencing obstructive sleep apnea;
  • You have an open bite where the upper and lower jaws cannot be fully closed.

What Does the Procedure Involve?

Stage 1: Consultation

  • Before the surgery, X-rays and CT scans will be taken of your teeth and face.

  • A general treatment plan will include fixing teeth straightening tools to align your teeth and jaw bone as much as possible before doing this surgery for the best results. The duration of this will be advised by the dentist and will depend on the severity of your dental condition and the progress of your tooth movement, which can last from 12 to 18 months.

Stage 3: Post-Operative Care 

  • After the surgery, you will remain in our medical facility for 2-3 days until your condition is stabilised. You will be given detailed post-operative care instructions. 


  • After your whole treatment course has been completed, you will be provided retainers and instructions for their wear. This will involve a lifelong wear period to secure a sustainable result. 

Stage 2: Orthognathic Surgery

  • Before the surgery commences, you will be placed under prior general anesthesia due to the complex nature of the procedure. The surgery will take 2 to 3 hours if one of the jawa need to be repositioned, or 4 to 5 hours if both jaws are to be moved.
  • The Dentist will engage in an “orthognathic workup” where 2-dimensional and 3-dimensional facial photographs, digital impressions of the teeth and a 3-dimensional facial x-ray (CBCT) will be taken to predict the direction the jaw alignment should be corrected exactly. 
  • The surgery varies depending on your current jaw structure. 
  • Once the teeth are appropriately aligned, jaw surgery can occur. Special hooks are applied onto the braces to ensure good bite alignment. These hooks are typically removed by your orthodontist 4-6 weeks after the operation.

What Are the Risks Involved?

Every surgery comes with its risks, as such you should be aware of some minor risks associated with this:
  • Infection;
  • Bleeding;
  • A permanent change in sensation, although usually rare.
