INTRODUCTION
Adult mandibular prognathia is treated with orthodontics and sagittal split ramus osteotomy (SSRO). Mandibular proximal segment stability in SSRO is important the prognosis Temporomandibular joint (TMJ) dysfunction. Therefore, magnetic resonance imaging (MRI) is gold standard. This case report, intraoral, extraoral and TMJ MRI results orthodontic and SSRO treatment of mandibular prognathia are presented.
CASE DESCRIPTION
Female patient (22 years old), student A.U. Faculty of Dentistry, complained about her face being long and having prominent lower jaw. There is asymmetric and flat profile, crowding dental arches, Class III molar-canine, anterior tet-a-tet relationship. He was asymptomatic in terms maximum mouth opening, amount lateral-protrusive movement, TMJ pain and sound during mouth open-close. Treatment goal was achieve facial aesthetics with dental class relationship.
Mandibular set-back with SSRO was planned treat negative overjet and prognathia inferior that occurred with decompensation during twelve-month orthodontic treatment. During surgery, proximal segment position was checked by ear canal examination for condyle displacement. TMJ was normal clinical examination and bilateral sagittal TMJ MRIs 45 days after surgery. 6-month postoperative orthodontic treatment was provide for interdigitation. End of the treatment, occlusion with aesthetic appearance and ideal maxillo-mandibular relationship was achieved.
DISCUSSION
Maintaining condylar position in SSRO is risky. In practice, method is check condyle by palpating external auditory canal during surgery. Risk of TMD is high as this is associated with clinical experience and skill. Postoperative TMJ MRI evaluation provides diagnostic accuracy.
CONCLUSION/CLINICAL SIGNIFICANCE
It has been determined MRI that subjective determination the condyle position during SSRO doesn't have negative contribution condyle and disc position.
