Comprehensive study of temporomandibular joint reconstruction1) Animal experiment with 5 joints of japanese monkeys-Reconstruction of temporomandibular joint (TMJ) with an artificial TMJ head and articular fossa and time-lapse observation of postoperative course ; Tissue samples showed the clinically useful finding that the interspace between titanium artificial joint and bone tissue was filled with new bone in the mandibular condylar cap.2) Artificial TMJ replacement ; Our research team has developed artificial TMJ replacement.The practical application of the system underwent in combination with articular disc-capsule sutural fixation under TMJ arthroscopy. The study of artificial TMJ replacement methods to be useful.3) Total evaluation of the artificial TMJ system ;Our reconstruction method was indicated in patients suffering from severe TMJ disturbance comlpicated by degenerative diseases including rheumatoid changesis, those who underwent this surgical procedure showed signifcantly good prognose, except two of fifteen cases applied this system. However, the optimum shape and size of the artificial TMJ and an adequate fixation method remain to be evaluated by further studies.

颞下颌关节重建的综合研究1)日本猴5个关节的动物实验——人工颞下颌关节头及关节窝重建颞下颌关节（TMJ）及术后病程的延时观察组织标本显示临床有用的发现，钛人工关节与骨组织的间隙在下颌髁帽内被新骨填充。2)人工TMJ置换术；我们的研究团队已经开发出人工颞下颌关节置换术。该系统的实际应用是在TMJ关节镜下结合关节盘-关节囊缝合固定。对研究人工TMJ置换方法有一定的参考价值。3)人工颞下颌关节系统总体评价；我们的重建方法适用于严重TMJ障碍合并退行性疾病（包括类风湿变性）的患者，除15例中有2例应用该系统外，接受该手术的患者预后显著良好。然而，人工TMJ的最佳形状和大小以及适当的固定方法仍有待进一步研究评估。
