OCCLUSAL ANALYSIS AND ASSESSMENT STUDY

The concept of “normal” is irrelevant and and often misleading in the field of dentistry and medicine.  What some may consider normal may not be normal for others when evaluating mandibular jaw positioning and functional responses of opening and closing of the jaw. What some clinicians may consider normal may in actuality be abnormal (pathologic) when physiologic parameters used as a baseline to objectively measure and compared to physiologic norms.

              

“Because most clinicians do not treat their TMD cases to know parameters of healthy they never know if their method and approach is on track or not…they just do what others taught them….not to measure or quantify their results of treatment. Subjective responses of hurting or not hurting or not in pain are not adequate when diagnosing or treating chronic fatigued TMD joint and muscular problems of the trigeminal nerve system.”

Without measured parameters in dentistry one will never know the many factors of whether the masticatory system (teeth, muscles, temporomandibular and CNS) are functioning optimally or whether there exists levels of impairment (dysfunction) when trying to re-establish maximum dental improvement (MDI) health.

3 Questions to Ask Yourself:

1. Is there any masticatory muscle dysfunction?
2. Is there any presence of pain?
3. Is there any joint derangement?

dis·a·bil·i·ty ˌdisəˈbilədē/ noun

1. a physical or mental condition that limits a person’s movements, senses, or activities.
   synonyms: handicap, disablement, incapacity, impairment, infirmity, defect, abnormality; condition, disorder, affliction
2. “my disability makes getting into bed a slow process”
3. a disadvantage or handicap, especially one imposed or recognized by the law.
   “he had to quit his job and go on disability”

OCCLUSAL STUDY and TESTING:

The K7 kineseograph occlusal evaluation system is able to assist the clinician in testing the masticatory system in determine the level of health (physiologic) versus levels of unhealth (pathologic – dysfunction and impairment) for following areas:

BEFORE TREATMENT:

1. Habitual resting ability of the masticatory system before TENS – Scan 9 EMG (measures in mV).
2. Functional recruitment ability of the masticatory muscles during clenching modes – Scan 11 EMG (measures in mV).
3. Quality of muscle balance timing during first tooth contact activity – Scan 12 EMG (measures in mV).
4. Functional mandibular open and closing ability and speed before TENS – Scan 2 CMS (measures in millimeters and ms/second) – jaw tracking.
5. 3 dimensional habitual resting freeway space before TENS – Scan 3 (measures in millimeters) – – jaw tracking.
6. Swallowing patterns before treatment – Scan 6 (measures in millimeters) – jaw tracking.
7. Functional chewing patterns before treatment – Scan 8 (measures in millimeters) – jaw tracking.
8. Mandibular range of motion before treatment – Scan 13 (measures in millimeters) – jaw tracking.
9. Joint sound analysis during functional mandibular open and closing cycles before treatment – Scan 15 (measures in millimeters and frequency levels) – ESG/jaw tracking.

AFTER TREATMENT:

1. Habitual resting ability after TENS – Scan 10 EMG (measures in mV).
2. Habitual trajectory vs. Myo-trajectory mandibular jaw location relative to CO after TENS – Scan 4/5 (measures in millimeters) – jaw tracking.
3. Functional mandibular open and closing ability and speed after TENS – Scan 7 CMS (measures in millimeters) – jaw tracking.
4. Swallowing patterns after treatment – Scan 6 (measures in millimeters) – jaw tracking.
5. Functional chewing patterns after treatment – Scan 8 (measures in millimeters) – jaw tracking.
6. Mandibular range of motion after treatment – Scan 13 (measures in millimeters) – jaw tracking.
7. Joint sound analysis during functional mandibular open and closing cycles before treatment – Scan 15 (measures in millimeters and frequency levels) – ESG/jaw tracking.

Any of these tests can be performed before to determine quality and level of functional health (dysfunction and or impairment) exists prior to, during and or after treatment in determining whether maximal dental improvement has been achieved or not. 

Mandibular movements/(function), temporomandibular joint function and muscle activity that does not operate to standards of physiologic health are considered dysfunctional or impaired.

Research and understanding starts with data and documentation of evidence. By recording before, mid and after treatment data the treating clinician can better learn what physiologic responses of his patient are working and what parts are not working. The prudent dentist will then further his study and treatment in a direction that respectfully addresses these responses to the masticatory system positively that will improve the patient’s health rather than by randomly and subjectively assuming certain procedures and modes of treatment he/she provides to the patient is OK.

MEASUREMENTS TELL US A LOT ABOUT THINGS WE WERE NOT AWARE OF PREVIOUSLY.
