Special Section CBCT Cone-Beam Computed Tomography Patient J.G. 8 years, 2 months Case Report Pre-Treatment How would you treat this malocclusion? This 8-year, 2-month-old Hispanic male has no chief complaint; however, his father is concerned about his lower front teeth sticking out (he points to the mandibular right central and lateral incisors). J.G. is extremely positive, happy, and easygoing. Cooperation is expected, although his mental development is delayed for his age. His history does not indicate significant medical or dental contraindications for orthodontic and craniofacial orthopedic therapy. He is generally healthy, with right-sided hemifacial microsomia and no history of trauma to the face or teeth. Regular dental care is provided in a safety net clinic. He has no caries and no restorative experience. Findings Analysis of the patient's relaxed frontal facial photograph reveals severely asymmetric upper, middle, and lower third facial development, with a decreased lower facial height. His relaxed profile photograph shows a concave lower facial pat- tern with an obtuse nasolabial angle, deep mentolabial fold with an everted lower lip, and a maxillary lip position that lies 1 mm behind the E-line. His smile reveals maxillary incisors undergoing eruption, and his lower right incisors and deciduous canines are prominent when he smiles. His maxillary dental midline is 1 mm to the right of the facial midline, while his mandibular dental midline is 7 mm to the right of the facial midline. Moreover, he has a moderate cant of the occlusal plane, with the right side more superior. He also displays a muscle imbalance: the masseter muscle is larger on the left side, and he has left-sided facial fullness. He has no parafunctional habits, and the results of a temporomandibular joint (TMJ) exam are within normal limits, but he does have a significant facial asymmetry. When his smile is evaluated from the profile, it can be seen that the upper incisor position is 3 mm behind the soft tissue glabella.
