The main questions it aims to answer are:\n\n* Does the surgical outcome recorded at the earlier 6-month follow up persist at the long-term follow up approximately 10 years postoperatively?\n* How does the radiologically determined degree of joint degeneration change with time in patients that have had joint surgery? Researchers will compare the six-month surgical outcome to the ten-year outcome to see if temporomandibular joint surgery results are stable over time.\n\nParticipants with an earlier performed joint surgery will:\n\n* Have a clinical examination approximately ten years postoperatively.\n* Have a temporomandibular joint x-ray scan performed (cone-beam computed tomography).",[71,72,73],"Temporomandibular Disorders (TMD)","Temporomandibular Joint Disc Displacement, With Reduction","Temporomandibular Joint Disc Displacement, Without Reduction","2025-12-09",{"date":76,"type":77},"2025-12-17","ACTUAL",{"date":79,"type":77},"2025-04-01",{"date":81,"type":66},"2026-05",{"name":5,"class":6},1]
