Background/Aim: Mandibular prognathism is a severe form of facial and jaw
deformity. Treatment of this anomaly usually requires combined
orthodontic-surgical therapy. The aim of this study is to determine the
changes in the craniofacial complex after orthodonticsurgical treatment of
patients with mandibular prognathism by analyzing the cephalometric
parameters on teleradiography images before and after treatment. Methods:
The study included a sample of 40 patients (mean age 24.1 ? 4.10) who
underwent orthodonticsurgical treatment of mandibular prognathism. Vertical
and sagittal parameters characterizing mandibular prognathism were measured
on profile teleradiography images before treatment and 12 months after
treatment. Based on the analysis of cephalometric parameters on preoperative
and postoperative teleradiography images, dental and skeletal changes that
occurred after treatment were determined. Results: After the end of the
treatment, all the parameters that characterize mandibular prognathism were
significantly reduced. A drop in parameters was noted like the following:
SNB, SNPg, NS/SpP, NS/MP, SpP/MP (<B), NSAr, ArGoMe, Bjork polygon, NMe,
NSna, SnaMe, SSnp, I/SpP. There was a statistically significant increase in
parameters: SNA, ANB, GoArNS, SGo, and i/MP. No statistically significant
changes in values were recorded on the OP/NS and SArGo parameters.
Conclusion: Orthodontic-surgical treatment leads to changes in the bone and
dental structures of the craniofacial system. As a result of such treatment,
there is a functional improvement and an improvement in the appearance of
the face.
