In accordance with the present invention, a mandibular staple bone plate
assembly, for use in retaining a dental appliance, namely dentures, within
the wearer's mouth comprises a flat elongated support plate having an
accurate configuration which corresponds to the curvature of the lower
surface of the front of the jawbone. Fixedly mounted to the support plate
are parallel, vertically extending cylindrical mounting posts, each having a
first end which is fixedly mounted to the support plate and a second end
extending outwardly from the plate. There are at least two posts, each of a
length sufficient to extend through the jawbone when the support plate is in
abutment with the lower surface of the front of the jawbone. The posts pass
through parallel bores formed in the jawbone which correspond in number and
size to the posts.
Threads are formed on the lower exterior surface of each post to increase
post surface area available for contact with bone tissue. The threads do not
extend upwardly far enough to enter the mouth or contact gum tissue which
may easily be irritated. The remainder of the post has a smooth outer
surface which eliminates irritation and facilitates mounting of a dental
Additionally, formed in the second end of each mounting post is a threaded
bore to which a retaining means may be attached. The retaining means may be
utilized to mount, fixedly or releasable, a dental appliance, namely
One such embodiment of the retaining means may comprise an elongated
appliance plate which has an accurate configuration similar to that of the
support plate described above. The appliance plate has receiving means
carried on a bottom portion thereof which engage corresponding mounting
means disposed on the second ends of the mounting posts. Engagement of the
mounting post mounting means with the appliance plate receiving means will
rigidly hold the appliance plate within the wearer's mouth in a fixed
position relative to the jawbone. The appliance plate will thereby provide a
rigid mounting base for a dental appliance, namely dentures.
A second embodiment of the retaining means may comprise a threaded adapter
which is threaded into the bore formed in the second end of the mounting
post. The adapter is utilized to retain one portion of a standard attachment
apparatus which is well known in the art. The other portion of the
attachment apparatus is mounted in the underside of the denture thereby
providing easy mounting and removal of the denture.
To assure that the mounting posts, extending into the wearer's mouth, are of
a proper length to engage the receiving means carried on the bottom portion
of the denture, thereby correctly positioning the denture within the mouth,
a flat elongated gauge plate, having an accurate configuration substantially
similar to the support plate is provided. The gauge plate may be of any
predetermined thickness corresponding to the desired mounting configuration
of the denture, and has mounting post bores, which correspond to the
mounting post locations. The gauge plate is placed over the second ends of
the mounting posts protruding from the lower jaw and the posts are
subsequently cut at the top surface of the gauge plate, thereby leaving the
mounting posts with a correct protruding length for proper engagement with
the denture. The gauge plate is then removed leaving the post ends at a
desired, uniform height.
In the case of post breakage, a replacement post may be provided which
threading engages the mounting post threads at a location below the gum
level. The replacement post utilizes a fixing screw which allows the
retention of the denture on the new post location.

A computer simulation of a dental articulator - Co-author John Knapp
The research described in this paper concerns a model of an articulator,
which is itself a mechanical model of the human jaw. These devices have
numerous adjustments which allow the user to simulate movement patterns
recorded previously from a patient. A mathematical model was devised to
duplicate the articulator movement patterns and display the results on a
graphics terminal. By varying adjustments in the simulated articulator, the
user may observe on the terminal the effects these changes have on the tooth
