3D Square-Jaw Surgery (Mandibular)

3D Square-Jaw Angle Reduction

 

3D Square-Jaw Surgery makes small and slim face line at from every angle including a 45° angle, lateral, front and back. Mandible angle resection not only removes protruded mandible angle, but it forms safe and beautiful facial contouring considering the ratio and harmony of the whole face.

 

The target of 3D Square-Jaw Surgery

  • Typical square jaw
  • Bones protruded from just below the ear even if it’s not square
  • Jaw looks bigger even though smooth face outline
  • The overall big jaw bone
  • Facial contouring problems
  • Mandibular asymmetry

Our Approaches to Jaw Surgery

The approaches to jaw surgery adopted by the Line Clinic are :

  • Surgery-first Approach

The surgery-first approach involves no preoperative treatment because the alignment and position of the patient’s teeth is already ideal for surgery – it is necessary to correct the alignment of the teeth before correct the position of the jaw. The surgery is done to correct the position of the jaw only. The total treatment time is shortened because there is no need to align the teeth through preoperative orthodontic treatment which usually lasts 1 to 2 years.

Following corrective surgery on the jaw, they may require postoperative orthodontic treatment like using retainers.

  • Conventional Method

In the conventional method, the patient’s teeth is not aligned properly thus they are first made to undergo orthodontic preoperative treatment. The preoperative treatment which usually lasts 1-2 years is meant to realign the patient’s teeth in preparation for corrective jaw surgery.

Generally, the conventional method takes longer time than the surgery-first approach. In this method also, the patient may or may not be required to undergo postoperative surgery depending on the outcome of the process.

  • Combined Conventional and Surgery-first Approach

This approach combines the processes of the conventional method and the surgery-first method. The differences being that the preoperative orthodontic treatment is done for a shorter period and postoperative orthodontic treatment is required.

In this method, the patient has only a slight tooth misalignment thus preoperative treatment is done for 3-4 months before corrective jaw surgery and after the surgery, the patient undergoes scheduled postoperative treatment.

Procedures Used In Corrective Jaw Surgery

Lower Jaw Surgery

  • Anterior Segmental Osteotomy (ASO) – in this procedure, the maxillary premolars on either sides of the mouth are removed together with the bone attached. After this, the anterior of the upper and lower mouth is moved backwards and affixed to the jaw using titanium plates. This procedure helps correct bimaxillary protrusion (protruding mouth).
  • Sagittal Split Ramus Osteotomy (SSRO) – cuts are made from 3 different regions of the mandible and at different angles.

A chisel is inserted in the cuts to separate the left mandible and the right mandible. All cuts must be made to extend to the middle of the bone where the bone marrow is. Following attachment of the chisel, the mandible may then be moved anteriorly or posteriorly. If the mandible is to be moved posteriorly, space must be provided for it to move in. The SSRO amends mandibular under-bite and overbite.

  • Vertical Ramus Osteotomy (VRO) – in VRO, the mandible is divided into a large segment made up of the mandibular body & the anterior body and 2 smaller segments with condyles. Unlike Bilateral Sagittal Split Osteotomy, there is lower probability of injury to the canal.

This procedure is used for shortening the posterior ramus, rotate the mandible but does not work for advancing the mandible or lengthening the ramus. In VRO, the osteotomy made to the rami are of full thickness.

Upper Jaw Surgery

  • Le Fort I Osteotomy – this procedure is the most commonly adopted procedure for the correction of the upper jaw. It involves making an incision shaped like the letter ‘U’ through the gums of the teeth of the upper jaw to get to the upper jawbone using specialized tools that permits the control of part of the bone. After this, the gum is lifted off the jawbone and fixed back after the procedure.
  • For this procedure, a general anesthetic is given to the patient to preclude pain while the process – which is done entirely in thw mouth – is on.

In cases where the jawbone is to be made longer, bone may be added to it through a process called bone grafting. However, if the jawbone is to be made shorter, bone may be removed from it. The jawbone is then moved to its new position ad fastened permanently with titanium screws and plates. The final position of the jawbone is decided before the surgery is done. When the bones heal and fuse together, the strength of the jawbone returns to normal.
