Six hundred consecutively debonded patients were retrospectively examined for the development of any temporomandibular joint signs or symptoms that developed during orthopedic/orthodontic treatment. Sixteen (2.6%) patients were found to have developed unexpected temporomandibular joint findings during treatment. Considering such a small sample, no conclusive results could be found, but several tendencies seemed to be apparent. Those types of patients who seemed to be most predisposed to developing temporomandibular joint problems included female Class II patients with excessive overjet and overbite and moderate to severe crowding of the lower arch. Ninety-three percent of the patients experienced posterior net condylar change in spite of using several different treatment mechanics. The types of treatments used included FJO appliances, headgear, Class II and Class III elastics, no elastics of any kind, extraction and nonextraction. This small study seems to suggest that temporomandibular joint signs and symptoms are changing, inconsistent, and ephemeral in many orthodontic patients regardless of the treatment mechanics.
对600例连续解除矫治器的患者进行回顾性检查，以了解在正畸/正颌治疗期间出现的任何颞下颌关节体征或症状。发现16例（2.6%）患者在治疗期间出现了意外的颞下颌关节问题。考虑到样本量较小，未得出确凿结果，但似乎有几种趋势较为明显。那些似乎最易患颞下颌关节问题的患者类型包括伴有过度覆盖、深覆合以及下颌牙弓中度至重度拥挤的女性安氏II类患者。尽管采用了几种不同的治疗方法，93%的患者仍出现了髁突后份净改变。所采用的治疗方法包括功能性矫治器、头帽、II类和III类牵引、不使用任何牵引、拔牙和不拔牙矫治。这项小型研究似乎表明，在许多正畸患者中，无论采用何种治疗方法，颞下颌关节的体征和症状都是变化的、不一致的且短暂的。
