بررسی ارتباط رادیوگرافیک شکل کندیل با الگوی رشدی صورت در بیماران دارای مال اکلوژن کلاس II اسکلتال

Mandibular shape is an important determinant in facial morphology, consequently, it should be paid special attention while investigating facial morphology changes. The aim of this study was to determine the relationship between condylar radiographic shape and facial growth pattern in patients with CI II skeletal malocclusion. The present retrospective study is of cross-sectional type, performed in Yazd dental faculty, on lateral cephalometric and panoramic radiographs of 40 patients. Cases, under study, had skeletal CI II malocclusion, with an age range of 9-12 years for females and 10-13 years for males. Condylar properties, including shape, neck width and inclination were investigated. To study theresults, X" test and pierson correlation coefficient were used. The findings showed that there is a significant relationship between condylar anterior angle and facial growth pattern. (PO.0001). This angle is increased in facial vertical growth pattern. Condylar flattening was observed in 57.5% cases, which didnot have any significant relationship with facial growth pattern. No significant relationship was found between facial growth pattern and condylar width.
