Condylar and mandibular morphological criteria in the 2D and 3D MSCT imaging for patients with Class II division 1 subdivision malocclusion

摘要: UNLABELLED The condyle has a special multidirectional capacity for the growth and adaptive remodeling of temporomandibular joint (TMJ). Being part TMJ structure, it plays an important role in stability long-term treatment results orthodontic orthognatic patients with Class II division 1 subdivision malocclusions. Several computed tomography (CT) investigation modes have been used to evaluate craniofacial morphology particularly, TMJ. Dimensional images, acquired using new generation multislice CT (MSCT) cone beam scanning data, are becoming increasingly popular clinical work research. aim study was develop protocol quantification morphological structures skeletal landmarks condyle, procesus condylaris mandible. For this purpose we created two dimensional (2D) three (3D) reconstruction images from primary axial MSCT scans IAC review Transparent bone programms accordant measurements condylar mandibular structures. This technic allowed get truly volumetric reflexion components its real anatomical size avoided bony superimpositions. Our material included 12 malocclusion who had indications combined treatment. examination performed before start statistical analysis paired Student t-tests were applied test diferences mean values correlation coefficients calculated assess possible interrelations between measurements. preliminary showed weak corrrelation More significant observed It difference right left side height without clinicaly relevant facial asymetry which could be considered individual planning CONCLUSION developed 2D 3D provides precise demonstrative quantitative relationships., qualified as informative criteria malocclusion.
