Dear Colleague:
The SOT Dental Research Update is a service
offered by
SOTO-USA to keep doctors who are familiar with
sacro
occipital technique (SOT) aware of the latest
TMD
related
research
related events, papers, and concepts.
Please contact Dr Blum directly at
drcblum@aol.com
if you are
aware of others who might be interested in
receiving
this
newsletter.
Please don't miss SOTO-USA's 8th Annual CLINICAL
SYMPOSIUM, October 23-26th, 2008, in Dallas,
Texas at the MCM
Elegante' Hotel & Suites (214) 351-4477.
Rooms are still available but are going
quickly, so please make reservations now.
The discount rate for early registration for the
symposium will only be available
until September 30, 2006 - so sign up NOW and
save!
Please go to www.SOTO-
USA.org to
begin the
process of registration.
This year's symposium will feature TMD
Dentists as
well as Chiropractors who specialize in TMD co-
treatment. Presenters will discuss multiple co-
treatment models for conditions including
body posture and occlusion with their
relationship to the
fields of dentistry and chiropractic. This
symposium is
an excellent place to network, as
chiropractors are
looking for dentists to whom they can refer
patients in
the treatment of TMD.

Examination of the relationship between mandibular position and body posture.
Cranio. 2007 Oct;25(4):237-49. Sakaguchi K, Mehta NR, Abdallah EF, Forgione AG, Hirayama H, Kawasaki T, Yokoyama A.
The purpose of this study was to evaluate the
effect of changing mandibular position on
body posture and reciprocally, body posture
on mandibular position.
Forty-five (45) asymptomatic subjects (24
males and 21 females, ages 21-53 years, mean
age 30.7 years) were included in this study
and randomly assigned to one of two groups,
based on the table of random numbers. The
only difference between group I and group II
was the sequence of the testing.
They concluded:
- Body posture was more stable when
subjects bit down in centric occlusion.
- Changes in body posture affected occlusal
force distribution.
- Altering body posture by changing leg
length shifted the occlusal force
distribution to the same side that had a heel
lift.
"In a clinical setting, when dental occlusion
is developed and finished, body posture
should be taken into account." "If a patient
has a length discrepancy, hip rotation or any
other problem altering body posture, occlusal
contacts may differ as the patient stands up
and starts walking."

Vertical Facial Dimensions Linked to Abnormal Foot Motion
Am Podiatr Med Assoc 2008;98(3): 189-196. Rothbart BA.Vertical Facial Dim
Background: 22 children from Juetepec,
Mexico, were studies to determine whether a
correlation exists among foot motion, the
position of the innominates, and vertical
facial dimensions.
Conclusions: An ascending foot
cranial model was theorized to explain the
findings generated from this study: 1) due to
the action of gravity on the body, abnormal
foot pronation (inward, forward, and downward
rotation) displaces the innominates
anteriorly (forward) and downward, with the
more anteriorly rotated innominate
corresponding to the more pronated foot; 2)
anterior rotation of the innominates draws
the temporal bones into anterior (internal)
rotation, with the more anteriorly rotated
temporal bone being ipsilateral to the more
anteriorly rotated innominate bone; 3) the
more anteriorly rotated temporal bone is
lined to an ipsilateral interior cant of the
sphenoid and superior canto of the maxilla,
resulting in a relative loss of vertical
facial dimensions; and 4) the relative loss
of vertical facial dimensions is on the same
side as the more pronated foot.

Effects of anterior cruciate ligament (ACL) injury on postural control and muscle activity of head, neck and trunk muscles.
J Oral Rehabil. 2006 Aug;33(8):576-87. Tecco S, Salini V, Calvisi V, Colucci C, Orso CA, Festa F, D'Attilio M.
The aim of the study was to evaluate the
effects that an anterior cruciate ligament
injury of the knee has on postural control
and activity of neck, head and trunk muscles
to investigate the existence of connections
between the masticatory system and body posture.
Surface electromyographic activity of the
muscles at mandibular rest position, and
during maximal voluntary clenching and
posturometric and stabilometric measurements
of 25 adult patients having pathology on the
left knee were compared with a control
non-pathological group.
At rest, the patients showed a higher
muscular activity of anterior temporalis,
masseter, sternocleidomastoid and lower
trapezius, compared with the control subjects
(P < 0.05). At maximal voluntary clenching,
the patients showed a lower muscular activity
of the right anterior temporalis and masseter
and a higher muscular activity of the lower
trapezius, compared with the control subjects.
Anterior cruciate ligament injury appears to
be associated to a change in the activity of
head, neck and trunk muscles and to a change
in the position of the postural centre of
pressure. Cotton rolls seem to improve the
stability of the subject.

Sacro Occipital Technique Organization - USA
is a
non-profit,
professional organization formed to promote the
awareness,
understanding and utilization of the Sacro
Occipital
Technique
method of chiropractic as founded and
developed by
Dr.
Major Bertrand DeJarnette.
Interdisciplinary co-treatment of TMD is an
important
part of
SOTO-USA's focus since TMD is a complex
condition. For the
chiropractor this necessitates their
understanding of
the
descending influences of occlusion, condylar
position and
airway disorders on posture. For the dentist
this
involves
gaining an awareness of ascending postural
influences on
craniomandibular function helping to guide
treatment
prior to
making any permanent occlusal or condylar
modifications.
