We describe the outcome of 46 patients 12 months after partial or total replacement of the temporomandibular joint (TMJ) using the Christensen implant system (TMJ Implants Inc, Golden, CO, USA). The study group comprised 35 women and 11 men; the women were slightly older than the men at the time of operation. We studied three diagnostic groups in detail: patients who had ankylosis, internal derangement, and osteoarthritis. Those with ankylosis were slightly older than the others. Pain decreased over time in all three groups. There was a significant reduction between preoperative pain and that recorded 1 month postoperatively. After this point the pain decreased slowly, and by year 1 it had decreased significantly with respect to preoperative scores. Women reported worse preoperative pain than men, but not significantly so.
我们描述了46例患者使用克里斯滕森种植系统（美国科罗拉多州戈尔登市的颞下颌关节种植体公司）进行颞下颌关节（TMJ）部分或全置换术后12个月的结果。研究组包括35名女性和11名男性；手术时女性比男性稍年长。我们详细研究了三个诊断组：患有关节强直、内紊乱和骨关节炎的患者。关节强直患者比其他患者稍年长。所有三组的疼痛均随时间减轻。术前疼痛与术后1个月记录的疼痛之间有显著降低。此后疼痛缓慢减轻，到第1年时，与术前评分相比已显著降低。女性报告的术前疼痛比男性更严重，但差异不显著。
