This study has been carried out in order to measure the thickness of soft-tissue on
lateral cephalograhphs based on body mass index(BMI) and the change in soft-tissue
thickness after surgical correction of mandibular protrusion. The control material in
cephalometric study comprised students at The Dental College, 38 persons, aged 21¡­24
years and the patient material comprised 20 women and 12men, aged 19¡­28 years with
mandibular protrusion. The thickness of the soft-tissue based on BMI in control and
study groups, the comparison between them, immediate postoperative change in the
thickness, 6 months after surgery, ratio of soft-tissue response and correlation was
established through various statistical methods.
The result were as follows :
1. The groups based on BMI showed significant differences each other as regards the
linear measurements.
The thickest soft-tissue was measured 13.6§®, 15.47§®, 16.76§® at Ss, the thinnest at
G' 6.0§®, 6.7§®, 7.26§® respectively
2. The differences between control and experimental groups based on BMI showed to
be significant. There were no differences at G'. The sort-tissue in prognathic patients
was thicker at Ss, Ls and thinner at Li, Ls, Pg', Gn', Me'. Differences gap was greater
in overweight groups.
3. The immediate soft-tissue change after surgery showed the increase at Li, Ls, Pg',
Gn', Me' except G' Ls in all groups.
4. The postoperative soft-tissue change 6 months after surgery was similar with
immediate change. The soft-tissue shows the increase in the thickness at Li, Pg', Gn',
Me' and the greatest difference occurred at Li, 1.1§®, 0.98§®, 1.2§® respectively.
5. The patients with lower BMI index showed higher soft-tissue response to bony
movement at Pg' The immediate response ratio was 91%, 87%, 81% in A, B, C groups
respectively, the response 6 months after surgery showed 96%, 91%, 84%.
