case report pre-treatment A video of this cAse cAn be found on our website: http://www.pcsortho.org How would you treat this malocclusion? Patient J.H. 61 years T his 61-year-old male presents with two chief complaints: "I am having trouble chewing" and "my bite seems to be getting worse." The patient is also motivated by a daughter who works in the dental field and has concerns that he could experience tooth loss if his malocclusion is not addressed. His medical history is non-contributory. He has a history of routine dental visits, but only recently started seeing a new dentist, who recommended an orthodontic consultation. A clinical TMJ evaluation displays normal range of movement without any pain, popping, or clicking. The patient is very motivated to improve his occlusion. PROFILE The patient presents in the permanent dentition with significant maxillary and mandibular incisal wear. His maxillary midline is coincident with his facial midline, and the mandibular midline is deviated 3 mm to the left of the maxillary midline. His maxillary arch is relatively U-shaped. There is 2 to 3 mm of maxillary arch length discrepancy. His mandibular arch is significantly omega-shaped, with lingually displaced mandibular premolars. There is 13 mm of mandibular arch length discrepancy and an exaggerated curve of 2015 * PCSO BULLETIN On the frontal facial photograph, the patient appears symmetric, with thin lips and 0 to 2 mm interlabial gap at rest. When smiling, the patient displays 90% of his maxillary incisors and has lingually inclined maxillary premolars, creating prominent buccal corridors. His smile is symmetric, and wear is evident on the maxillary incisors and canines. He has a convex profile and a strong chin button. FRONTAL INTRAORAL FINDINGS SPRING EXTRAORAL FINDINGS SMILING Spee. He presents with complete buccal crossbites of the mandibular premolars and an impinging deep bite. He has Class I molars on both sides, with severely worn mandibular incisors and moderately worn mandibular canines. His mandibular premolars have erupted lingually and he has 2 to 3 mm of exposed root surfaces. Due to the position of the mandibular premolars, his maxillary first premolars have supererupted 2 to 3 mm, and his second premolars have supererupted 1 to 2 mm. His maxillary and mandibular molars display very little wear. 27 http://www.pcsortho.org
