Why it matters for dental

Longer closed-lock duration in temporomandibular joint disorders correlates with higher rates of disc perforation and degenerative changes visible on arthroscopy; oral surgeons and TMD-focused practices should consider earlier arthroscopic evaluation in patients with prolonged locking to limit irreversible joint damage.

Key points

  • Study published online 18 September 2026 in Journal of Oral and Maxillofacial Surgery links longer closed-lock duration to increased prevalence of disc perforation and degenerative arthroscopic findings.
  • Findings apply to oral and maxillofacial surgeons and specialists managing TMD cases where conservative treatment fails.
  • Results suggest that prolonged locking may drive structural joint damage, influencing timing of surgical referral decisions.
