1. Composi-Tight® Sectional Matrix System User Training
Mention that already about 15% of the US. dentists are users and about 22% of Canadian Dentists
Discuss that sell well in Scandinavia and getting started in the U.K. and Switzerland. Several interested distributors in Germany, France and Italy, as well as several inquiries from Eastern Europe.

2. Composi-Tight® solves one of the most common and frustrating problems for dentists placing posterior Class II composite restorations:
Achieving tight, anatomical contacts

3. Problem & Solution Tofflemire v. Composi-Tight®

4. Matrix Bands and G-Rings®

5. Instructional Video
Covers basic technique, MODs, wide embrasures and back-to-back restorations.
Duration: 12 minutes

6. GDS Ring Placement Forceps
GDS forceps open wide enough for all applications and hold the rings stable for easy placement and removal.
Ivory-style rubber dam forceps may also be used to place G-Rings, however, some styles do not open the rings wide enough to place them on larger teeth.

7. PLACING THE MATRIX SYSTEM

8. - Pre-curl band and place matrix
Go briefly through how the system works
- Place rubber dam
- Prepare tooth
- Pre-curl band and place matrix

9. - Insert wedge to seal cervical margin

10. - Spread G-Ring with GDS Ring Placement Forceps or rubber dam clamp forceps

11. - Place ring adjacent to band when possible
- Burnish band against adjacent tooth

12. - For wide embrasures, place ring on
opposite side of wedge

13. - For MODs, place long ring over
standard ring

14. FEATURES AND BENEFITS MATRIX BANDS

15. Matrix Bands Key Features & Benefits
Feature: 5 band sizes
Benefits:
Sizes for every application
PEDO for primary molars
SMALL for bicuspids
EXTENDED SMALL for bicuspids & molars with sub-gingival extensions (NEW PRODUCT)
STANDARD for permanent molars & bicuspids
LARGE for deep cervical/sub-gingival extensions
Places contact at the height of contour
Small bands reduce over-filling, which reduces finishing time.

16. Matrix Bands Key Features & Benefits
Feature: 3-Dimensional Contour
Benefits:
Contact is at the height of contour
No loss of contact during occlusal adjustment
Broader area of contact
Reduces gap below the contact area

17. Matrix Bands Key Features & Benefits
Feature: 30 Microns Thick (.0012”)
Benefits:
Less separation of teeth required
Easier to slide band into place (don’t need to cut as much tooth structure when breaking contact)
Easier to burnish and broaden contact area

18. Matrix Bands Key Features & Benefits
Feature: Sectional Piece
Benefits:
Easier to burnish - slides over easily
Easier to place band on Class 2 filling (it is very difficult to get a contoured Tofflemire-type matrix between the contact opposite the side being restored)

19. FEATURES AND BENEFITS G-RINGS®

20. G-Rings® Key Features & Benefits
Feature: 2 Lengths of Tines
Benefits:
Overlap of rings for MODs or multiples in a quadrant
Long ring often helpful for restorations on taller teeth or tooth with periodontal disease

21. G-Rings® Key Features & Benefits
Feature: Converging Tine Angle
Benefit:
Helps ensure ring retention (compare to parallel tines of Palodent BiTine ® ring)

22. G-Rings® Key Features & Benefits
Feature: Burnished Ends of Tines
Benefit:
Helps ensure ring retention (compare to tines of Palodent and Danville Rings)

23. G-Rings® Key Features & Benefits
Feature: Round (versus flat) Wire
Benefit:
Allows placement alongside wedge
Wedge must be trimmed with competing rings
Reduces time (no trimming or difficulty removing)
Restores wide lingual or buccal embrasures
Adapts well to interproximal space for either mesial or distal condition
Competing rings require turning the ring around for distal restorations

24. Answers to Commonly Asked Questions
How do I handle wide embrasures?
Option 1: Place ring opposite the wedge
Option 2: Fill and cure all but interproximal contact area, then place matrix
My rings have lost their tension.
Open rings only as far as necessary
Re-set tension with 3-prong pliers or orthodontic headgear pliers

25. Answers to Commonly Asked Questions (continued)
My forceps don’t open rings far enough for some applications
Use GDS Ring Placement Forceps
Grasp ring higher up on an ivory-style rubber dam forceps

26. Answers to Commonly Asked Questions (continued)
The matrix bands are difficult to place.
Break contact with very thin diamond
Pre-curl matrix and slide in laterally
Place ring during cavity preparation, then remove and place matrix
My contacts are sometimes too tight.
Lighter wedging ( especially w/ new rings)
Remove band with hemostats or dressing forceps (Miltex 6-8) with interlocking teeth

27. Answers to Commonly Asked Questions (continued)
Sometimes I still don’t get a contact.
Don’t forget to burnish.
Wedge a little more firmly if needed
How do I restore a back-to-back MO/DO.
Fill and cure one side first using only wedge and band. Then, finish other side using wedge, band and ring. Be sure to burnish band against the already restored tooth

28. Answers to Commonly Asked Questions (continued)
Do you offer clear bands?
No clear bands offered at this time
Incremental filling, and increased bond strengths eliminate the need for a clear matrix.
Clear bands are typically 2 or 3x as thick, non-contoured, and lack resilience of stainless steel, making them more difficult to use.

29. Answers to Commonly Asked Questions (continued)
Can it be used for amalgam?
The system was designed and developed for composites.
Contacts very good, but if amalgam is not fully set it can fracture when removing the matrix band.
Recommend lubricating matrix first.

30. Clinical Technique

31. Amalgams to be replaced.

32. Amalgam was removed with as little loss of tooth structure as possible.

33. Caries detector applied to preparation.

34. Precurled contoured bands are pulled through the open contact area from the lingual (or vice versa).

35. Bands and wedges are placed on the MO and DO preparations only.

36. MO and DO are filled.

37. Bands and wedges are removed and the proximal surfaces are finished.

38. Bands are placed first, then wedges, then rings
Bands are placed first, then wedges, then rings. The rings serve to create separation and ensure excellent contacts. The rings hold the band tightly to the proximal cavosurface margins, greatly reducing flash.

39. Anatomy is roughed in before removal of rubber dam, significantly reducing occlusal adjustment time.

40. Finished quadrant of composite restorations.
