Abstract：
Condylar resorption of temporomandibular joint findings in the panoramic radiographs is an indication of bone resorption suggesting possible degenerative joint disease that warrants early screen and subsequent referral to a dedicated specialist. This case series reports three patients that underwent the active orthodontic treatment for the duration of approximately 24-36 months. The patients were asymptomatic at the initial examination. The clinical examination was negative for clicking; the range of motion on opening, lateral excursion, and protrusion was normal. Neither of these patients had a history of rheumatic disease or bruxism. During the later stages of orthodontic treatment, two of the three patients reported mild pain and clicking during mastication, which was also confirmed chairside on clinical evaluation. Patients were referred to the orofacial pain specialist, were they were prescribed specific medication for the symptoms, along with cognitive behavioral therapy, and were further evaluated for splint therapy. Panoramic radiographs taken before the start of the treatment, during the treatment and at the completion of the orthodontic treatments indicate the progression in the resorption of mandibular condyle in all three patients suggesting possible degeneration that warrants further investigation and therapy.
摘要：
全景X射线照片中颞下颌关节的髁突吸收表明骨吸收，提示可能的退行性关节疾病需要早期筛查并随后转诊给专门的专家。该病例系列报告了3例接受了大约24-36个月的积极正畸治疗的患者。患者在初次检查时无症状。临床检查对点击是否定的；打开时的运动范围，横向偏移,突出是正常的。这些患者均无风湿性疾病或磨牙症病史。在正畸治疗的后期，三名患者中有两名报告在咀嚼过程中轻度疼痛和咔嗒声，这也得到了临床评估主席的确认。患者被转诊到口面部疼痛专家，他们是否为症状开了特定的药物，以及认知行为疗法，并进一步评估夹板治疗。在治疗开始前拍摄的全景X光片，在治疗期间和正畸治疗完成后,3例患者下颌髁突吸收均有进展,提示可能发生退变,需要进一步研究和治疗.
