Mastoid augmentation (chin augmentation) artificial bone

Artificial bone (Biopex) is inserted at the tip of the chin to form a beautiful impression of the jawline.
A clean jawline tightens the mouth and gives a balanced impression to the entire face.

Recommended for this type of person

Those with small, receding chins.
Short jaw
For those who want to have a sharp chin
Those who wish to have a face line.

Features of this hospital

In the surgery, a 3 cm incision is made in the oral cavity and an artificial bone is inserted under the periosteum.
The artificial bone is firmly fixed to prevent postoperative movement, and the wound is sutured neatly.
*The clinic uses the 3D simulation software "vectra" before surgery to provide a 3D image of the post-operative result, and the ideal size of the artificial bone prosthesis is decided together with the patient during the consultation.

-Hydroxyapatite Artificial bone (hydroxyapatite preparation)

A 3D printer is used to create a facial bone model from CT data of the patient's facial bone, and an artificial bone prosthesis is created before surgery.
It takes a little more preparation time, 2-3 weeks from CT scan to surgery, but not only anterior protrusion of the mussel but also downward protrusion is possible.
In addition, since it fits perfectly with your own bone, the risk of postoperative misalignment is greatly minimized.

Postoperative risks and side effects

-Philadelphia infection
If there is prolonged "heat," "redness," "severe pain," or "severe swelling" in the treated area after surgery, infection is suspected.
If left untreated, the skin may break, pus may appear, or the prosthesis may pop out, so treatment is always necessary.
-Hematoma hematoma
If blood accumulates due to postoperative bleeding, the jaw and neck may swell to a purple color. If the blood is left to pool, it may become infected or form a lump, so it must be treated as soon as possible.
-Dr. Numbness in the jaw
When a pocket is made for the prosthesis, it is stripped near the sensory nerve and the nerve is pulled, which may cause a loss of sensation from the jaw to the gums of the jaw. It varies from person to person, but in most cases it resolves within a year. In rare cases, sensation may never completely return to normal.
-Dr. Bent or misaligned prosthesis
Although the inserted prosthesis is immobilized in a cast for 3 days after surgery to prevent it from moving, bending or misalignment may occur due to pressure from the jaw muscles. If the patient is concerned about the postoperative bending, the position of the prosthesis will need to be corrected between one and three months after the surgery, depending on the situation.
