2. Alameter
developed by Dr. Frush 1960
• For determining the correct width of the six anterior arch segment
• Selection of anterior teeth

3. Alameter
developed by Dr. Frush 1960
• For determining the correct width of the six anterior arch segment
• Selection of anterior teeth

4. Caliper
• For determining the correct width of the six anterior arch segment
• Selection of anterior teeth

5. Papillameter
developed by Dr. Frush 1960
• For determining the length of the upper lip and the anterior teeth
14 mm

6. 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

7. (ECB) Esthetic Control Base

8. Rim Former
Product benefits
• Ensures parallelism between upper and lower rims
• Functional design
• Simple handling

9. Use an extra hard sheet
wax, soften over a flame
and mold onto model

10. While wax is still soft
bend around aveolar
ridge region

11. Reference Papillameter measurement from operative appointment

12. Carve divot in base of place calipers in divot,
model and open to papillameter
measurement

13. Transfer Papillameter measurement to ECB

14. Rimformer- an integral tool for creating the ECB
Wax reservoir
Hamular notch rim channel

15. Melt wax keeping
Rimformer securely in
hamular notch

16. Melt to Papillameter mark

17. Mark midline

18. Use Alameter measurement to establish buccal corridor

19. Create bucccal corridor using the Rimformer
Hold the Rimformer
tilted to the lingual
Start to melt from
the tuburasity
area, and melt
forward to the
distal point of the
canine

20. Alameter, Papillameter, and Rim Former
ECB (esthetic control base)
• Papillameter measurements for
Proper length of centrals
• Alameter measurements for
Proper width of six anterior arch segment
• Mid-line
• High lip line

21. Vertical and Centric

22. VCR Kit – Vertical and Centric Recorder Kit
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

23. 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

24. While pressing the
striking plate down, align
to the alatragus plane of
the model

25. Level with the hamular notches

26. Place bar in center of mark

27. 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

29. 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

30. Over opened

31. Over closed

32. Correct vertical - lips should be touching

33. Step 2:
Establishing Centric

34. Ink striking plate

35. Mandible in rear most position

36. Mandible in forward most position

37. Slide lower jaw forward and back
Do this several
times, moving the
jaw forward and
back

38. Slide lower jaw forward and back
pushing the condyles back as far as possible

39. With mandible in REAR most position
slide mandible right then left

40. Do this several
times, moving the
jaw to the left and
the right

41. In rear most position
slide left and right

42. An arrow is created
The tip of the arrow being the central bearing area
Balanced pressure
Balanced pressure

43. Tip of arrow is the central bear area
Repeat if necessary
steps

44. Place centric stop on tip of arrow

45. Lute centric stop to
the striking plate,
with hole of stop
over the tip of the
arrow

46. Patient will position pin
in hole of centric stop

47. verify the pin has
dropped into the
hole of the centric
stop

48. Mix a quick setting plaster

49. The thickness of the
mix should be like
thick sour cream

50. Load the plaster mix into a large barrel
syringe, like the one you would get in
the Accu-dent impression system kit.

51. Patient must keep mouth securely closed,
with pin in centric stop.

52. Inject plaster starting in the back over the retromolar pad, and move forward to the
tuberasity area

53. Solid bite block for mounting on an articulator

54. With proper vertical and centric
to create balanced occlusion

55. Thank you for your attention.
