<prompt> Malocclusionrepresentinga transverse deficiency is often referred to as:Open biteClosed biteCrossbiteDeep bite  <response>: ACKERMAN-PROFITT SYSTEM OF CLASSIFICATIONCHARACTERISTIC 1 ALIGNMENTIntra arch alignment and symmetry are assessed as when seen in the occlusal view.A dental arch is classified as ideal crowded spaced.CHARACTERISTIC 2 PROFILEThe profile can be convex straight concave.This also includes the assessment of facial divergence, i.e. anterior or posterior divergence.CHARACTERISTIC 3 TRANSVERSE RELATIONSHIPSThey include transverse skeletal and dental relationships.Buccal and palatal crossbites are noted. These are further subclassified as unilateral or bilateral.Distinction is made between skeletal and dental crossbites.CHARACTERISTIC 4 CLASSHere, the sagittal relationship of the teeth is assessed using the Angle classification as Class I Class II Class III.A distinction is made between skeletal and dental malocclusions.CHARACTERISTIC 5 OVERBITEMalocclusions are assessed in the vertical plane.They are described as anterior open bite posterior open bite anterior deep bite posterior collapsed bite.Here, again a distinction is made as to whether the malocclusion is skeletal or dental.
