The Damon system is an effective, less-invasive treatment that provides orthodontic dentists with an adequate biomechanical process, offering a reduction in treatment time; patients with temporomandibular dysfunction present even greater complexity in their clinical picture, relying on clinical and radiographic differential diagnoses to facilitate a good prognosis. The objective was to apply the orthodontic treatment (Damon technique) to stabilize patients with temporomandibular dysfunction. The patient with premature loss of the first lower molars (36 and 46) experienced pathological alterations in the temporomandibular joints (TMJs) (bilaterally). The diagnosis was reached using the clinical history of temporomandibular joint disorders (diagnostic criteria) axis II: moderate pain (VAS) in muscles, moderate stress (Hamilton 51/60), lateral and panoramic cephalic radiographs, magnetic resonance imaging of bilateral TMJ, cephalometry, photographs, and models. Treatment with the Damon system is recommended to recover optimal functional occlusion in a short period, followed by referral for oral rehabilitation as an adjunct to the treatment plan. The verticalization of the second molars, maximum optimal intercuspidation, appropriate overbite and overjet, and pain control in the TMJ were evaluated. Stabilization of the disc condyle complex by eliminating interference and premature points of contact providing cervical/cranio/mandibular balance.
戴蒙系统是一种有效、侵入性较小的治疗方法,为正畸牙医提供了充分的生物力学过程,可缩短治疗时间;颞下颌关节功能紊乱患者的临床表现更为复杂,需依靠临床和影像学鉴别诊断以获得良好预后。目的是应用正畸治疗(戴蒙技术)来稳定颞下颌关节功能紊乱患者的病情。该患者双侧第一恒下磨牙(36和46)过早缺失,颞下颌关节出现了病理改变。通过颞下颌关节紊乱的临床病史(诊断标准)轴II:肌肉中度疼痛(视觉模拟评分法)、中度应激(汉密尔顿51/60)、侧位和全景头颅X线片、双侧颞下颌关节磁共振成像、头影测量、照片及模型做出诊断。建议采用戴蒙系统进行治疗,以在短时间内恢复最佳功能咬合,随后转诊进行口腔修复,作为治疗计划的辅助手段。评估了第二磨牙的直立、最大最佳牙尖交错、适当的覆合覆盖以及颞下颌关节的疼痛控制情况。通过消除干扰和早接触点来稳定盘髁复合体,实现颈/颅/下颌平衡。
