Conservative Therapies for TMJ Closed Lock: A Randomized Controlled Trial.

Area of Science:

• Dentistry
• Orthodontics
• Temporomandibular Joint Disorders

Background:

• Acute anterior disc displacement without reduction (ADDWoR) causes TMJ disc displacement, pain, and limited function.
• Occlusal appliances (OA) are a primary treatment for ADDWoR.
• This study compares two OA types for ADDWoR treatment efficacy.

Purpose of the Study:

• To compare the therapeutic success of RA.DI.CA splints versus stabilization splints in patients with ADDWoR.
• To evaluate the impact of splint therapy on temporomandibular pain, headache, neck pain, and jaw function.

Main Methods:

• A single-blind randomized controlled trial involving 30 patients with ADDWoR.
• Group I (n=15) received RA.DI.CA splint therapy; Group II (n=15) received stabilization splint therapy.
• Outcomes assessed at baseline, 4 weeks, and 6 months, including pain levels and functional jaw movements.

Main Results:

• Both splint types improved maximum jaw opening and reduced pain (p < 0.05), except for neck pain in Group II.
• Significant improvements were observed in both groups over time, with Group I showing a greater positive trend.
• RA.DI.CA splints demonstrated superior efficacy in improving functional movements and managing associated pain.

Conclusions:

• RA.DI.CA splints appear more effective for treating ADDWoR in this patient sample.
• The enhanced orthopedic action and joint mobilization of RA.DI.CA splints may contribute to their superior outcomes.
• RA.DI.CA splints show promise for improving function and treating comorbidities associated with ADDWoR.
