Skeletal Occlusion Abnormalities
Mandibular distoclusion occurs when the mandible is caudal to its normal relationship with the maxilla.
Mandibular mesiocclusion occurs when the maxillary incisors occlude caudal to the mandibular incisors.
Mandibular gingival ulceration from maxillary incisors
Other Skeletal Occlusion Abnormalities
Canine level bite
Canine open bite
Canine caudal crossbite
Wry Bite (MAL/WRY)
Wry bite is a condition where one or more of the jaw quadrants are out of proportion to the other three, causing a deviation from the midline.
Normal Canine Position
Some orthodontic abnormalities are genetic. Others are not. Normally the mandibular canine should be positioned perfectly between the maxillary third incisor and canine.
Normal cheek teeth position
Normal interdigitation of check teeth
Excessive freeway space – genetic defect
Abnormal interdigitation genetic malocclusion and posterior crossbite
