A Comparative Study Using Two 3D Printed Occlusal Splints for Patients With Tempromandibular Disorder

A Comparative Study Using Two 3D Printed Occlusal Splints for Patients With Tempromandibular Disorder (A Randomized Cross Over Clinical Trial)

• to compare the relief of pain for patients with anterior disc displacement with reduction between two groups; in the first group a digitally formed stabilizing splint followed by an anterior repositioning splint (ARS) and the second group a digitally fabricated (ARS) splints followed by a stabilizing splints

Inclusion Criteria:

• • TMDs according to the research diagnostic criteria (RDC)8 which include: i. Painful TMJ audible and palpable click unilateral or bilateral ii. Presence of clicking during opening. iii. TMJ tenderness.

  • Fully dentate patients without any malocclusion (natural or restored by fixed prothesis) and good oral hygiene.
  • Co-operative patient that should show motivation to follow up.

Exclusion Criteria:

• • Patients with systemic diseases which could affect TMJ, e.g., rheumatoid arthritis, osteoarthrosis, Myasthenia Gravis and fibromyalgia.

  • Patients taking analgesic, muscle relaxant, or anti-inflammatory drugs were excluded because such drugs could influence the results.
  • Patients with removable dental prosthesis
