facial (working BULL)
Location of NON-Working Side interferences– parallel to the _______ groove on the Maxillary 1st molars
distal oblique groove
Location of NON-Working Side interferences– parallel to the _______ groove of mandibular 1st molars
DF developmental groove
Location of WORKING side interferences- lingual inclines of the maxillary posterior ______ cusps.
facial
Location of WORKING side interferences- facial inclines of the mandibular posterior _____ cusps
lingual
Location of Protrusive interferences- ______ marginal ridges of the mandibular posterior teeth.
distal
Location of Protrusive interferences- ______ marginal ridges of the maxillary posterior teeth
mesial
Lateral Displacement of the Mandible, due to Occlusal Prematurities: A and C contacts will display Medial and Lateral Pterygoid contracture on the ________ side.
OPPOSITE
Lateral Displacement of the Mandible, due to Occlusal Prematurities: A and C contacts- The Masseter and Posterior/Middle Temporalis are contracting on the _______ side of the interference.
SAME
Lateral Displacement of the Mandible, due to Occlusal Prematurities: “B” contacts will display Medial & Lateral Pterygoid contracture on the ______ side.
SAME
Lateral Displacement of the Mandible, due to Occlusal Prematurities: “B” contacts-The Masseter and Posterior/Middle Temporalis are contracting on the _______ side of the interference.
opposite
_________= a deviation in position of form of the tissues WITHIN the capsular apparatus of the temporomandibular joint, essentially giving rise to an abnormal relationship of the articular disc to the condyle, mandibular fossa and/or articular eminence.
Internal Derangement
_________ = problems and clinical conditions associated with the temporomandibular joint that are contained WITHIN the capsular apparatus (i.e., the immediate joint tissues)
Intracapsular TMD
__________ = problems and clinical conditions associated with the temporomandibular joint that are OUTSIDE the joint (i.e., the muscles of mastication and many ligaments)
Extracapsular TMD
___________ = is used to describe a number of different common painful states characterized by the presence of TRIGGER points within the affected muscle(s). This syndrome is a common source of low-back pain, neck pain, shoulder pain, chest pain, and rib pain
Myofascial Pain Dysfunction Syndrome (MDPS)
___________ = physical dislocation or displacement of the articular disc, either anterior to or posterior to the head of the condyle
Articular Disc Displacement
_________ = a popping sound from the articular disc, exhibited as a forceful “jumping” back or “snapping” over the head of the condyle, usually occurring during the early opening or late closing condylar movement
Reciprocal Clicking
_________ = an internal derangement of the temporomandibular joint in which the articular disc is dislocated anteriorly and usually medially to the condyle. The articular disc is physically incapable of reducing or receding posteriorly into position on the head of the condyle.
Closed Lock
___________= The determination of one of two or more conditions a patient is suffering from by systematically comparing and contrasting their historical and clinical findings.
Differential Diagnosis
The etiology of temporomandibular dysfunction (TMD) includes 1) ________ factors: These will increase risk, 2) _______ factors: These are responsible for the onset of the disease, and 3) ________ factors: These will interfere with healing or enhance progression of the disease
1) Predisposing 2) Initiating 3)Perpetuating
What are the 5 major factors for the etiology of TMD?
Occlusal, Trauma, Emotional Stress, Deep pain, Parafunction
TRIGGER POINTS- Masseter
maxillary and mandibular posterior teeth
TRIGGER POINTS- anterior temporalis
maxillary incisors
TRIGGER POINTS- middle temporalis
maxillary PM’s and Molars
TRIGGER POINTS- Posterior temporalis
posterior cranium
TRIGGER POINTS-medial pterygoid
the TMJ!!! (think thats an important one!??!?)
TRIGGER POINTS- Lateral Pterygoid
zygomatic arch AND TMJ
What are these symptoms describing? Joint sounds, limited opening with a HARD end feel, pain during loading of the TMJ, and sudden change in a patient’s occlusion
Intracapsular TMD = HARD end feel
Disc Displacement with a reciprocal click: ______ click (regaining position), ______ click (articular disc pops out of position to the anterior, very near closed, and ______ click (implies that there are 2 clicks, one on opening and one on closing)
opening…closing…reciprocal
Parafunctional Activities and Features: Clenching, Bruxism, parafunctional activities occur at a _________ level, occlusal prematurities do not directly cause ______ events, emotional ______ directly relates to parafunction
SUBCONSCIOUS…BRUXING…STRESS!!!! (in the sim clinic maybe?!?)
