[Masticatory pattern of patients with TMJ clicking]

Area of Science:

• Biomedical Engineering
• Dental Science
• Biomechanics

Context:

• Temporomandibular joint (TMJ) disorders are common.
• Clicking sounds are a frequent symptom of TMJ dysfunction.
• Understanding the biomechanical impact of TMJ clicking is crucial for diagnosis and treatment.

Purpose:

• To investigate the relationship between TMJ clicking sounds during mastication and masticatory performance.
• To identify specific characteristics of chewing movements associated with TMJ clicking.
• To quantify the influence of clicking sounds on the mechanics of chewing.

Summary:

• Electrognathography was used to record chewing movements in the sagittal plane for 36 patients experiencing TMJ clicking.
• A comparison was made between chewing movement patterns and the electronic records of clicking sounds.
• Four distinct features of chewing movements were identified that correlate with the occurrence of TMJ clicking.

Impact:

• This research provides objective biomechanical data on how TMJ clicking affects chewing.
• Findings can inform the development of more targeted diagnostic tools and therapeutic interventions for TMJ disorders.
• Establishes a foundation for further studies exploring the functional consequences of TMJ clicking.
