Rim Former
Device for parallel forming/melting of bite rims to hamular notch
Product benefits • Ensures parallelism between upper and lower rims• Functional design• Simple handling
(ECB) Esthetic Control Base
Product benefits • Ensures parallelism between upper and lower rims• Functional design• Simple handling

Rim Former
Use an extra hard sheet wax, soften over a flame and mold onto model
While wax is still soft bend around aveolar ridge region
Reference Papillameter measurement from operative appointment
Carve divot in base of model
place calipers in divot, and open to papillameter measurement
Transfer Papillameter measurement to ECB
Rimformer- an integral tool for creating the ECB
Hamular notch rimWax reservoir channel
Melt wax keeping Rimformer securely in hamular notch
Melt to Papillameter mark
Mark midline
Use Alameter measurement to establish buccal corridor
Create bucccal corridor using the Rimformer
Start to melt from the tuburasity area, and melt forward to the distal point of the canine
Hold the Rimformer tilted to the lingual
Alameter, Papillameter, and Rim Former
• Papillameter measurements forProper length of centrals
• Alameter measurements forProper width of six anterior arch segment
ECB (esthetic control base)
• Mid-line
• High lip line
Vertical and Centric
Product• This Intra Oral balancer can be used for all dental restoration when vertical
and centric relation needs to be established.
Product benefits • Improves function of the dentures• Proper centric relation• Physiologic vertical dimension• Allows free movement of the condyles
VCR Kit – Vertical and Centric Recorder Kit
Vertical and Centric Recorder
Includes:
2 Striking plates
2 Long bars
1 Short Bar
3 Long screws
1 Short screw
3 Threaded sleeves
3 Nuts
5 Plastic stops
1 Screw driver
1 Inking pen
1 Wrench
While pressing the striking plate down, align to the alatragus plane of the model
Level with the hamular notches
Place bar in center of mark
Top of the bar is to the middle of the retromolar pad
Place bar from anterior to posterior, parallel to the angle of the alatragus plane
VCR Kit – Vertical and Centric Recorder Kit
• Vertical - Physiologic rest
• Centric –Unguided Left to right and protrusive and retrusive mandibular movement produces gothic arch tracing
Over opened
Over closed
Correct vertical - lips should be touching
Step 2:
Establishing Centric
Ink striking plate
Mandible in rear most position
Mandible in forward most position
Slide lower jaw forward and back
Do this several times, moving the jaw forward and back
Slide lower jaw forward and backpushing the condyles back as far as possible
With mandible in REAR most position slide mandible right then left
Do this several times, moving the jaw to the left and the right
In rear most position slide left and right
An arrow is createdThe tip of the arrow being the central bearing area
Balanced pressure
Balanced pressure
Tip of arrow is the central bear area
Repeat if necessary steps
Place centric stop on tip of arrow
Lute centric stop to the striking plate, with hole of stop over the tip of the arrow
Patient will position pin in hole of centric stop
verify the pin has dropped into the hole of the centric stop
Mix a quick setting plaster
The thickness of the mix should be like thick sour cream
Load the plaster mix into a large barrel syringe, like the one you would get in the Accu-dent impression system kit.
Patient must keep mouth securely closed,with pin in centric stop.
Inject plaster starting in the back over the retromolar pad, and move forward to the tuberasity area
Solid bite block for mounting on an articulator
With proper vertical and centricto create balanced occlusion
Thank you for your attention.
