Introduction
Temporomandibular disorders (TMD) are frequently managed through irreversible prosthodontic or pharmacologic pathways without adequately addressing functional occlusion. This case highlights occlusal disequilibrium as a primary etiological driver, demonstrating rapid symptom resolution through selective occlusal correction, avoiding prosthetic replacement.

Case Presentation
A 33-year-old male presented with:

·         Right-sided temporomandibular joint pain

·         Ipsilateral masseteric tenderness

·         Functional discomfort during mandibular closure

 

Relevant Dental History

·         Immediate implant placement (lower left posterior region) ~3–4 years prior

·         Extraction followed by all-ceramic fixed partial denture (~2 years prior)

·         Persistent pain onset post-restorative phase

·         Inconsistent follow-up due to international travel

The patient had previously been advised prosthesis removal and replacement.

 

Clinical Examination

·         Initial occlusal contact on left posterior segment

·         Mandibular shift into maximum intercuspal position (MIP)

·         Evidence of premature contact with slide-induced occlusal instability

·         Right-sided muscular hyperactivity consistent with protective co-contraction

 

Diagnosis

Occlusal interference–induced temporomandibular dysfunction
with secondary myofascial pain involving the ipsilateral masseter.

Treatment Protocol
A minimally invasive, function-first approach was adopted:

·         Selective occlusal adjustment targeting premature contacts

·         Establishment of simultaneous bilateral posterior contact in MIP

·         Elimination of deflective occlusal pathways

·         No modification or replacement of existing prosthesis was performed.

Outcome
Within approximately 30 minutes:

·         Significant reduction in TMJ pain

·         Improved mandibular range of motion

·         Palpable decrease in ipsilateral muscle tenderness

Follow-Up (1 Week)

·         Symptom stability maintained

·         No recurrence of pain

·         Adjunctive physiotherapy advised for neuromuscular conditioning

Discussion
This case reinforces a critical but often overlooked principle:- Occlusion is not merely structural—it is neuromuscularly determinant.

 

Key Clinical Insights

·         Premature contacts can induce mandibular deflection, leading to asymmetric muscle loading

·         Chronic adaptation results in myofascial pain and TMJ overload

·         Prosthetic replacement without correcting occlusal dynamics risks persistent or recurrent symptoms.

 

Why This Matters

·         Over-treatment via prosthetic replacement is common

·         Functional occlusal correction remains underutilized

·         Immediate symptom resolution suggests reversible neuromuscular pathology, not structural degeneration

 

Clinical Implications for Practice

·         Always evaluate initial point of contact vs MIP

·         Identify and eliminate deflective contacts before considering prosthetic revision

·         Integrate occlusion–muscle–joint relationship into TMD management protocols

 

Referral Perspective
This case underscores the value of interdisciplinary awareness:

·         Prosthodontists → Functional occlusal diagnostics

·         Physiotherapists → Muscle reconditioning

·         TMD specialists → Long-term joint stability

Early referral for occlusal evaluation can prevent unnecessary restorative interventions.

Conclusion
Selective occlusal correction can provide rapid, non-invasive resolution of TMJ symptoms in cases driven by occlusal interference. Recognizing functional discrepancies before structural intervention is critical for predictable outcomes.
