Bonding Products

 3M products
Optibond products
Bisco

4th Generation - gold standard. 1 etch 2 rinse 3 prime 4 bond more technique sensitive Top 3
  • 3M Adper Scotchbond Multi-purpose plus
  • Optibond FL
  • All-Bond 2

5th Generation - 1 etch 2 rinse 3 prime and bond. not all adhesives in this category are compatible with DC and SC composites because the lower pH of the oxygen inhibited layer de-activate the tertiary amine in chemical cured composites.
  • Optibond Solo Plus adds a dual cure activator, benzene sulphinic-acid/sodium salt solution, to raise pH.  With that it can bond to DC and SC but the extra chemical lowers bond strength.
  • 3M Adper Single bond plus, Excite, Prime&Bond NT
6th Generation - selective etch products
Type 1 - 1 etch and prime 2 bond.
  • Clearfil SE Bond, AdheSE
Type 2
  • All-Bond SE, Adper Prompt L-Pop, Xeno III
7th Generation - selective etch with a all-in-one consistency
  • Clearfil S3 Bond
  • G-Bond, Futurabond DC, Bond Force, Xeno IV
Universal (2011) Compatible with both total and self etch systems, works with both dual and self cure products, primer for silica and zirconia.
  1. Differs from 7th in that can bond dentin after phosphoric etch due to higher pH
  2. Contains Silane (ceramic) and/or acidic monomer like MDP (zirconia) Tests show coat silane still improves and HF is mostly responsible anyway so not sure much advantage. 1
Scotchbond Universal has silane and phosphate monomer
All-Bond Universal found spot said has phosphate monomer BUT said needs Z-Prime still?? 1
Voco Futrabond U  is DC universal

Steps

  1. Seat patient confirm completing filling on tooth listed today.
  2. Place bid
  3. Dry mucosa at site of injection and place topical with cotton gauze or roll over top
  4. If anterior filling check shade with mock composite
  5. Doctor deliver first step anesthetic
  6. Doctor deliver second step anesthetic
  7. ASK patient feels numb
  8. Remove decay and bevel all enamel edges
  9. Use Viscostat, cords, or traxodent as needed.
 Anterior filling Total etch technique
  1. Place mylar strip and wave wedge
  2. Etch enamel 15 seconds and dentin 10 seconds then wash and dry (with bac etch)
  3. 2% CHX unknown duration 30-60 sec suggested (only beneficial on areas etched) air dry
  4. Gluma 10-20 seconds with scrubbing in dentin and air dry
  5. If deep, line dentin with RMGI (but etch and CHX steps get moved to right after this step)
  6. Step 1 Optibond Fl Prime 15 seconds scrubbing then air dry 5 sec
  7. Step 2 1 tooth?=same brush Optibond Fl Adhesive 15 seconds scrubbing then air thin 3 sec
  8. Cure
  9. Layer composite curing as needed
  10. Peel mylar strip back place flowable comp IP and pull mylar through and cure
Buccal filling Total etch technique
  1. Place #0 cord soaked in hemodent
  2. Etch enamel 15 seconds and dentin 10 seconds then wash and dry (with bac etch)
  3. 2% CHX unknown duration 30-60 sec suggested (only beneficial on areas etched) air dry
  4. Gluma 10-20 seconds with scrubbing in dentin and air dry
  5. If deep, line dentin with RMGI (but etch and CHX steps get moved to right after this step)
  6. Step 1 Optibond Fl Prime 15 seconds scrubbing then air dry 5 sec
  7. Step 2 1 tooth?=same brush Optibond Fl Adhesive 15 seconds scrubbing then air thin 3 sec
  8. Cure
  9. Layer composite curing as needed
  10. Remove cord
Posterior filling Selective etch technique
  1. Place V-ring if IP
  2. Etch enamel 15 seconds then wash and dry (with bac etch)
  3. 2% CHX unknown duration 30-60 sec suggested (only beneficial on areas etched) air dry
  4. Gluma 10-20 seconds with scrubbing in dentin and air dry
  5. If deep, line dentin with RMGI (but etch and CHX steps get moved to right after this step)
  6. Step 1 Clearfil SE Protect prime and etch 20 seconds with scrubbing then air dry
  7. Step 2 Clearfil SE Protect bond, air thin then cure 5-10 seconds
  8. Burnish metal matrix if needed
  9. Layer composite curing as needed
  10. Removal V-ring, wedge, and peel back matrx to cure IP
 Finish and polish
  1. Bulk reduction excess composite
  2. Check occlusion and excursion with Troll foil
  3. Check contacts with floss
  4. Fine tune with finishing burs
  5. Polish
Total etch article is good
6 month test showing total etch maintains bond strength best
Kanca article on moist bonding with total etch technique
Kanca article on HEMA.

Kanca says HEMA is acting as the wetting agent, most glutaraldehyde products also contain that.
