If it is a slight chin retraction, it can be treated by chin augmentation. For example, fat it here, or silica gel and detumescence can make the chin longer, warped and pointed. If the chin is severely retracted and accompanied by skeletal deformity, it must be surgically corrected.
Dentofacial malformation refers to the abnormal jaw size and morphology caused by abnormal jaw development, abnormal relationship between upper and lower jaws and other craniofacial bones, and accompanying abnormal jaw-tooth relationship, oral and maxillofacial system function and facial morphology.
The purpose of orthognathic surgery is to correct the dislocated teeth, adjust the disharmony between the dental arch and the dental jaw, eliminate the interference of the dental jaw, arrange the dentition, eliminate the compensatory inclination of the teeth, make the bone cutting segment move smoothly to the designed correction position during the operation, and establish a good dental jaw relationship.
Early career:
As early as 1928, Fauchard tried to correct individual tooth dislocation with dental forceps at one time, but the surgical correction of skeletal dentofacial deformity was created by Hullihen in 1848 and first reported in 1849.
Since then, although many scholars have made efforts to explore and improve, but limited by the level of science and technology and medicine at that time, the treatment effect is not ideal, so that in the next nearly 100 years, the treatment of dentofacial deformities has made slow progress.
Until the end of 1950s, with the application of anesthesiology, surgical basis, applied anatomy and special surgical instruments, the surgical correction of dentofacial deformities made rapid progress.
