MANAGEMENT OF TMD Clinical A/P Chua Ee Kiam PRINCIPLES OF TREATMENT Treatment should be based on specific diagnosis Treatment should address the cause of symptoms Treatment should reflect relative urgency of the symptoms TREATMENT GENERAL PRINCIPLES Reduce pain Reduce functional overload Provide stabilization Improve function Prevent progression of problem TREATMENT EMERGENCY TREATMENT PATIENT EDUCATION MEDICATION APPLIANCE THERAPY JAW MANIPULATION ARTHROCENTESIS ARTHROSCOPY PHYSIOTHERAPY COUNSELLING JAW SURGERY OCCLUSAL REHABILITATION OTHERS (INCLUDING RE-TREATMENTS) TREATMENT EMERGENCY TREATMENT (following acute trauma) Ice pack moist heat reduce function anterior appliance anti-inflammatory medication TREATMENT EMERGENCY TREATMENT (following acute trauma) Ice pack moist heat reduce function anterior appliance anti-inflammatory medication ACUTE PAINS & PROBLEMS 1. First episode of pain & difficulty of mouth opening 2. Traumatic trismus 3. Locked 4. Chronic problem becoming acute 5. Trauma 6. Problems with appliance 7. Worried parents, friends and lovers 8. Emotional crisis 9. Dislocation 10.Flare-up of rheumatoid arthritis or systemic problems 11. Effects from unconventional treatments 12. Flare-up from disc surgery TREATMENT PATIENT EDUCATION Limited function protocol Reduce trauma Exercises TREATMENT MEDICATION NSAIDS Muscle relaxants (x) Low dose antidepressants (x) Steroids (x) TREATMENT The arachidonic acid pathway constitutes one of the main mechanisms for the production of pain and inflammation, as well as controlling homeostatic function. The pathway produces prostaglandins (from cyclooxygenase metabolism) leukotrienes ( from lipoxygenase metabolism) PROSTAGLANDIN PATHWAY Stimulus Phospholipids Phospholipase A2 Arachidonic Acid Enzyme - Lipoxgensaes ( Leukotrienes ) . Enzyme- Cyclooxygenases (COX 1 & 2) (Prostaglandins) important mediators of inflammation TREATMENT The COX-1 is related to the toxicity and COX 2 is specific to inflammation. Traditional NSAIDs are considered "nonselective" because they inhibit both COX-1 and COX-2. The inhibition of COX-2 by traditional NSAIDs accounts for the anti-inflammatory effect of the drugs while the inhibition of COX-1 can lead to NSAID toxicity and associated side effects (ulcers, prolonged bleeding time, kidney problems). COX-2 is usually specific to inflamed tissue, there is much less gastric irritation associated with COX-2 inhibitors Inhibition of COX-1 undesirable while inhibition of COX-2 is considered desirable. MEDICATION Muscle relaxants behavioural addiction effects high for significant acute pain never in chronic pain eg. Valium 5mg 1 nightly MEDICATION NSAIDS weaker anti-inflammatory than steroids inhibits the metabolism of arachinodic acid to prostaglandin require 5 days to reach peak blood levels eg Ponstan 250mg Naprosyn 375mg tid Ibuprofen 600mg tid Feldene 10mg bid MEDICATION Ultracet (1 tab = tramadol 37.5mg + 325mg paracetamol) 1-2 tab qds x 5/7 Arcoxia (etoricoxib 120mg) I tab a day x 5/7 Celebrex (celecoxib 200mg) I tab a day x 5/7 MEDICATION Tri-cyclic antidepressants (TCAD) prevent re-uptake of (NA & 5HT) into presynaptic nerve endings increases post synaptic receptor sensitivity in low dose - useful in pain management Amitriptyline MEDICATION Steroids used to suppress inflammation Kopp & Wenneberg, 1981 reported significant benefits Poswillo, 1970 found erosions of condyles of monkeys after multiple intra-articular injections MEDICATION b) Steroids eg.

I recently got one and it seems to be making things worse. The muscles in my eyes/ face have totally seized up and it feels like the same with my jaw (even though I am not able to clench anymore). I'm totally upset, this cost me $850 and it's making it worse. I wear it all day/ night and only take it out to eat. When I eat it feels like my mouth and bite is all out of wack. Is it common to get worse before better???? *NTI-tss (Nociceptive Trigeminal Inhibition-tension suppression system) TREATMENT JAW MANIPULATION determine site stabilize the patient guide condyle medially and anteriorly engage the disc maintain open position ultrasound therapy TREATMENT PHYSIOTHERAPY CRYOTHERAPY MOIST HEAT ULTRASOUND INTERFERENTIAL THERAPY TENS JAW EXERCISES STRETCHING EXERCISES TREATMENT PHYSIOTHERAPY CRYOTHERAPY CRYOGEL PACKS (POLYVINYL ALCOHOL GEL IN POLYTHELENE-VINYL ACETATE BAG) TREATMENT PHYSIOTHERAPY CRYOTHERAPY Cold impulses negate pain impulses; breaking the cycle of pain metabolites - muscle spasms - pain At lower temperature muscle activity is sustained for longer periods without fatigue PHYSIOTHERAPY MOIST HEAT silica gel in canvas heated to 65-82 deg C for 1/2 hour used to increase blood flow and relax muscles PHYSIOTHERAPY ULTRASOUND (0.75 -3 mHz) acoustic vibrations propagated in the form of longitudinal mechanical waves these cause alternate compressions and rarefactions depolymerizes proteins (decreasing viscosity of hyaluronic acid higher the frequency, shorter the wavelength, greater the absorption has thermal and mechanical effects ULTRASOUND CONTRAINDICATIONS Brain, Spinal Cord, Eyes, Reproductive organs Acute Infections DXT Haemophiliacs Deep Vein Thrombosis PHYSIOTHERAPY TENS sensory pathways are affected large fibres are stimulated blocks small activity and stop pain signals being transmitted PHYSIOTHERAPY INTERFERENTIAL CURRENT THERAPY The high frequency carrier waveform penetrates the skin more deeply than a regular TENS unit, with less user discomfort for a given level of stimulation. Stimulation is characterized by the crossing of two electrical medium, independent frequencies that work together to effectively stimulate large impulse fibers. When two differing unmodulated medium frequency (around 4000 Hz) alternating currents are applied to tissues, a vibration (interference currents between 1 & 100 Hz) is generated Facilitating ionic movement of cells (increased cellular activity & active hyperaemia) Useful for pain relief swelling control Relaxes muscle spasm PHYSIOTHERAPY JAW EXERCISES Keeping teeth apart in clenching Limiting jaw opening in hyper-mobile joints Jaw strengthening exercises To encourage active movement of “sticky” displaced disc PHYSIOTHERAPY STRETCHING EXERCISES SYSTEMATIC REVIEWS ON TMDS - TREATMENT PHYSICAL THERAPY 1.
