Augmentation of a retrognathic chin. I. Use of HTR-polymer implants in a long-term prospective clinical and radiographic study.
A total of 37 patients have had chin augmentation procedures with HTR-polymer implants. Indications were mandibular retrognathia in connection with dentofacial deformities in 13 and the remaining 24 had a normal occlusion. Three patients with micrognathia also had juvenile rheumatoid arthritis. The patients have been followed for at least one year and in 17 cases up to five years both clinically and radiographically. Cephalometric measurements of the effects and stability of augmentation showed that chin augmentation has highly predictable results, and few side-effects.
