									                        Partial Denture Design Package


This package intends to guide the user through the decision making process
for prescribing a Removable Partial Denture.
In Dental practice, it is the responsibility of the clinician (dentist) to design
partial dentures, and prescribe the construction of these dentures from the
dental technician.
For many dentists this is a time consuming and difficult process as there are
many options available and the process is carried out irregularly.
Consequently the design is often produced by the technician.

The result of this design process will be a simple line diagram that acts as the
prescription along with written instructions to the technician.

The software should propose components that the user should be able to
adjust on the screen in a simple a quick way.

Stage 1/7.

Instruction: Select the remaining natural teeth Note: You will be able to adjust the position
of the teeth at the net stage.

Action: User Clicks on the remaining teeth

Result: All other teeth disappear and a proposal of the saddle area appears

Design Rule: Draw saddle area where teeth have been removed
with the exception of the 8th tooth

changed by dragging or adjusting the boundary of the saddle.

Action: User drags the teeth to desired position, edits saddle
area or adds a further saddle area.

Result: Teeth and saddle area are move accordingly and tooth
support is proposed.

Design Rule: Occlusal rest placed on teeth adjacent to the
saddle areas. On closest side of the tooth to the saddle where
saddle area has teeth both sides (bounded saddle).
On opposite side to the saddle where ‘free ended saddle.
Also write in Notes to Dentist box: Check Occlusion and cut rest seats to prevent occlusal
interference where opposing natural teeth. This denture should be produced in cast CoCr.

Action: User drags occlusal rest, deletes or clicks Add to place
an additional rest.

Result: Occlusal rests are placed and retentive clasps are
proposed.

Design Rule: Clasps are placed on adjacent teeth to saddle
area. Occlusally approaching on teeth 4,5,6,and 7 and ginivally
approaching on teeth 3. No clasps are placed on teeth 1 or 2.
Occlusally approaching clasps on 6 or 7 start at the occlusal rest
and wrap around the buccal side of the tooth to the distal corner.
Occlusally approaching clasps on 4,5 wrap around the buccal aspect to the mesial or distal
corner, that furthets from the saddle area.
Gingivally approahing clasps start in the saddle area and contact the buccal side of the
tooth

Also write in Notes to Dentist box: Check whether ample undercut is present at proposed
sites. Consider moving clasp tip or creating undercut.

further clasp.

Result: Clasps are moved accordingly and reciprocation is
proposed.

Design Rule: Reciprocation may be provided by a plate or a ‘clasp’ arm. Propose
reciprocation on the opposite side of the tooth to the clasp tip. Propose plates on 3 and
4’s. and arms on distal teeth.
Also write in Notes to Dentist box: Consider cutting guide planes to aid reciprocation and
retention.

Instruction: Adjust the reciprocation design, add or delete
plates and arms.

Action: User drags reciprocation to desired position, deletes
or adds a further plates or arms.

Result: Reciprocation is moved accordingly and connector is
proposed.
Design Rule: Connectors may be produced in CoCr or Acrylic. Propose connector in
CoCr where occlusal rests have been incorporated, and acrylic otherwise.
Design the connector to cover as much of the remaining area, linking all components while
stay 3mm away from natural teeth which are component free.

For Lower RPD, Need to set inner boundary of denture bearing area.

Also write in Notes to Dentist box: Consider strength of connector and whether to extend
connector to remaining natural teeth.
