What is 3D square jaw reduction?

3D square jaw reduction of IWELL not only cut the broad region of mandibular angle, but also performs cortex osteotomy to effectively reduce the thickness of chin, completing the slender facial type.

Not just square jaw excise, but also the
“square jaw region beneath molar”!

3D square jaw reduction of IWELL not only cut the square region, but also the square jaw region beneath molar to create small and slender facial line. If this part isn’t excised, the broad bone part next to mentum resides, decreasing the distinctive effectiveness of the surgery.

Patented “Retractor for square jaw surgery to
prevent damage to vessel and nerve”

In IWELL, we developed the “retractor for square jaw surgery to prevent damage to vessel and nerve” based on persistent research and clinical experience and received patents from independent technology as well as stability.


  • By identification the location of neural pass way and chin bone through 3DCT, we understand the surgical area as well as vessel and face bone tissue
  • By osteotom in long curve from beneath the ear to frontal chin, we remove unnecessary muscle and fat.
  • Minimal dissection of mouth and minute incision method of soft-tissue
  • By lifting soft-tissue and fixation, sagging is not a worry

3D square jaw points

Depending on the thickness of bone, size of square jaw, and degree of muscle development, this surgery reduces overall volume of the face; even with same surgery, individual diagnosis must be performed to consider individual differences. 3D square jaw reduction of IWELL completes beautiful facial line by applying appropriate surgery method.
