Are occlusal factors related to TMD?
Proper occlusion of the dentition occurs in a dynamicrelationship with the oral and facial musculature, periodontium, supporting osseous framework, temporomandibular joints, and the enveloping
neuromuscular system.

TM Joint:Affects of Reduced Loading
• Improved mesenchymal cell reprogramming
• Facilitation of pseudodisc formation
• Facilitation of condylar remodeling
• Reduction in amount of cellular debris
• Decreased synovial irritation

Pseudodisc Hypothesis
When subjected to constant repetitive compressive forces and loading, the retrodiscal tissue may transform
into a disc‐like tissueinto a disc‐like tissue.

Pseudodisc Hypothesis
Many TM joints display an adaptive capacity to remodel themselves and continue to function without ideal discthemselves and continue to function without ideal disc
position.

Disc DisplacementWithout Reduction (Chronic)
• Sudden onset of limited mouth opening that occurred at some time in the past
• History of clicking that ceased with sudden onset of y glocking
• Soft tissue imaging reveals displaced disc without reduction
• Condylar remodeling• May be painful or painless• Gradual resolution of limited mouth opening
Disc Displacement Without Reduction (Chronic)Degenerative Joint Disease
A chronic inflammatory or non-inflammatory disease resulting in joint deformity caused by degenerative
changes in the articular cartilage fibrous connectivechanges in the articular cartilage, fibrous connective tissue, and/or the articular disc within the
temporomandibular joint.

Degenerative temporomandibular jointdisease is the result of maladaptation
to increased joint loading.

52 year old female
Chief concern: bilateral pre-auricular pain (severe) with swelling
Clinical Findings
• TM joint– Severe pain at lateral and posterolateral aspects on palpation bilaterally
– Severe pain on loading bilaterally
– Maximum painless opening 15mm
– Course crepitus
• Masticatory musculature– Generalized moderate pain on palpation

TMD:
Masticatory and CervicalMuscle Pathology
Patient: M.M.
Primary concerns:
-bi-temporal headaches-facial swelling-jaw pain when awakenjaw pain when awaken-sore/sensitive teeth-non-restorative sleep-fatigue
Myositis
Inflammation of a muscle, usually due to local causes such as infection or injury.
• Increased pain with mandibular movement
• Onset following prolonged or unaccustomed use
• May be localized or generalized
• Limited range of motion due to pain and swelling
Myositis
• Patient education
• Eliminate / minimize cause
Management Considerations:
– Avoid exercise, stretching, muscle injections
• Restrict masticatory function
• Pharmacotherapy– Analgesic / anti‐inflammatory
– Antibiotic(?)
• Physical therapy
• Control parafunctional behavior(s)
Patient: D. B.
Chief concerns:-painful limited opening of sudden onset-left side pre-auricular swelling
3838
Protective Muscle Splinting
Restricted or guarded mandibular movement due to a co-contraction of muscles as a means of avoiding pain caused
by movement.
• Severe pain with function, but not at rest
• Marked limited range of motion without significant increase on passive stretch
Protective Muscle Splinting
• Patient education• Eliminate / reduce etiologic factor(s)
Management Considerations:
• Stabilization orthotic• Pharmacotherapy
– Analgesic / anti‐inflammatory– Muscle relaxant
• Control parafunctional behavior(s)• Physical therapy
Myospasm(Acute Trismus, Cramp)
An involuntary, sudden tonic contraction of a muscle.
• Acute pain
• Continuous muscle contraction (fasciculation)
• Increased EMG activity even at rest
Myospasm(Acute Trismus, Cramp)
• Patient education
• Eliminate cause
Management Considerations:
• Restrict function to within painless limits
• Pharmacotherapy– Muscle relaxant
– Analgesic
• Behavior modification
• Physical therapy
• Stabilization orthotic

• 28 year old Caucasian male
• Medical history:– non-contributory
Patient: MarcusChief pain concern:
“I have a toothache in my lower right molar area”
Radiographic and clinical findings (intraoral assessment)were non-contributory to determination of a diagnosis.
Patient: Marcus
• Aggravating factors:– chewing
– clenching
• Alleviating/relieving factors:– analgesics (NSAIDs, opioids)
Patient: MarcusChief pain concern:
“constant toothache, even where I don’t have teeth any more”

• Greater awareness does not come in a single blinding flash of enlightenment.
The Future
• It comes slowly piece by piece, and each piece must be worked for by the patient effort of study and observation of everything, including ourselves.
