Fifteen fully dentated patients with pain and functional impairment due to unilateral temporomandibular joint disc displacements, who had undergone unsuccessful nonsurgical treatment, were treated with discectomies without any disc substitutes and followed for 5 years. Their contralateral temporomandibular joints were without any clinical or radiographic evidence of pathology. Functional pain was reduced and mandible opening ability increased although a full range of motion was not restored. This study verified that discectomies can reduce pain on chewing, however, pain at rest was not significantly changed. At 5 years 87% of the patients fulfilled the criteria for a successful result of TMJ surgery.
15例因单侧颞下颌关节盘移位而出现疼痛和功能障碍且非手术治疗失败的全牙列患者接受了无任何盘替代物的关节盘切除术，并随访5年。他们对侧的颞下颌关节没有任何临床或影像学病理证据。尽管未恢复全范围活动，但功能性疼痛减轻，下颌开口能力增加。本研究证实关节盘切除术可减轻咀嚼时的疼痛，然而静息时的疼痛无明显变化。5年后，87%的患者符合颞下颌关节手术成功结果的标准。
