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%.
