HELPING YOU PREVENT
BITE CHANGES
A undesirable,
lthough generally
side effects are
one of the costs of doing
business in the delivery
of healthcare solutions. In
Oral Appliance Therapy,
unwanted tooth movement,
discomfort and bite changes
rank at the top of the “what
keeps you up at night”
list. Precision engineered,
bilateral and symmetrical
titration along with the
retainer like fit of the new
device materials and design
go a long way at mitigating
the first two, which leaves
the question, “how do we
prevent untoward bite
changes?”
Like the artisanal
manufacturing of handmade
appliances, the intraoral
fabrication of a Morning
Aligner or Morning Occlusal
Guide (MOG) has been
the only methodology
available until recently.
The AADSM (1) recommends
use of a MOG to mitigate
side effects of OAT for SDB.
The goal and use of these
are recommended in the
October 2017 JDSM.

• Function:
MOGs are devices
designed to reposition
the mandible into its
pre-treatment position.
• Indication:
MOGs are intended to
address the occlusal
discrepancy noted after
removal of the OA device
each morning.
• Patient Use:
Each morning the
patient should bite
into the [MOG] until
the maxillary and
mandibular teeth are
fully seated for as long as
it takes the teeth to re-
establish occlusion.
ProSomnus ® Sleep
Technologies has recently
launched two precision
engineered and milled MOG
variants made out of the
same control-cured PMMA
that their devices are made
from, the ProSomnus [MOG]
and the ProSomnus [MOG]
MIP.
Both have a ramp that
guides the mandible back
from the advanced position
towards MIP. The [MOG] MIP
has perforations where the
posterior occlusal contacts
will be, that confirms the
end point and returns to the
original pre-treatment bite.
The original [MOG] ramp
places the mandible on
the correct trajectory, the
patient’s normal occlusal
contact can be confirmed
after removal.
