Description
A dental treatment using a custom-fitted acrylic appliance worn over teeth to manage bruxism and temporomandibular disorders by reducing muscle activity, protecting dentition, and stabilizing jaw joint function.
Main Uses
Primary clinical uses include: (1) reducing nocturnal tooth wear and enamel damage in diagnosed sleep bruxism; (2) alleviating myofascial pain, joint loading, and disc displacement symptoms in temporomandibular disorders (TMD); (3) serving as a diagnostic tool to differentiate muscular vs. articular TMD components via symptom response; (4) stabilizing occlusion during acute TMD flare-ups; and (5) acting as an interim measure prior to definitive occlusal rehabilitation or surgical evaluation.
Normal Range
Occlusal splint therapy (for bruxism/TMD) is a non-invasive clinical intervention, not a laboratory or imaging test with numerical values; therefore, there is no 'normal range' of quantitative metrics. Clinical success is assessed qualitatively via symptom reduction (e.g., ≥50% decrease in jaw pain, headache frequency, or tooth wear progression over 4–12 weeks), stable occlusion on articulating paper marks, and absence of splint-induced discomfort or occlusal interference.
Low Values - Possible Causes
Inadequate splint design (e.g., improper thickness or material hardness), poor patient compliance (inconsistent nightly wear), incorrect diagnosis (e.g., treating central sensitization or sleep apnea as primary bruxism), insufficient follow-up adjustments, or underlying untreated psychiatric comorbidities (e.g., unmanaged anxiety or depression).
High Values - Possible Causes
Overly aggressive splint design (e.g., excessive anterior guidance or premature contacts causing iatrogenic occlusal instability), excessive splint wear duration beyond therapeutic need (>6–12 months without reassessment), concurrent untreated systemic conditions (e.g., Parkinson’s disease or GERD exacerbating parafunction), inappropriate splint type selection (e.g., full-coverage stabilization splint used for sleep bruxism without polysomnography confirmation), or patient-related factors like chronic clenching habits reinforced by splint feedback.
