Indirect Bonding
The author wishes to give credit to his mentor, Dr. Michael Wainwright of Vancouver, B.C., who is one of the pioneers of indirect bonding and who taught the author the original indirect bonding technique in 1981.

In-Vitro Comparison of Three Indirect Bonding Adhesive Systems

Taken from Summary and Conclusions:
"Based on the data obtained in this in-vitro study, it thus appears that the modified Higgins indirect bonding system is superior to both the auto-cure (A-B) system and the Thermacure system. The modified Higgins indirect bonding system yielded SPBS (Shear-peel bond strength) values comparable to directly bonded brackets, without any apparent increased risk of enamel damage at debonding."

Procedure for Indirect Bonding to Porcelain Crowns and Veneers:
Interface Ceramic Primer (Apex Dental Materials, Inc.) etches and silanates porcelain prior to placing Ortho Solo without using hydrofluoric acid. Prophy all teeth and then roughen the porcelain with a diamond bur in a slow speed handpiece. Isolate with the Nola Dry Field. Etch, rinse, dry, and place Ortho Solo where bonding to enamel. Use Interface on the roughened porcelain as follows:
Preparation of Interface
Interface is furnished in two bottles, labeled A and B, along with a mixing well and Microtip®
applicators.
1) A drop of Interface A and a drop of Interface B are dispensed into the same cavity of the mixing
well. At first the two liquids will not mix- one will form a “bubble” on the top of the other.
2) After 20-30 seconds, the bubble will break down, and at that time the mixture is stirred for 5 seconds
with the Microtip® applicator.
Note: The mixed Interface solution must be used within 3 minutes. Once it has become cloudy or opaque it is no longer useful.
Delivery of Interface
1) Using a Microtip® applicator, apply an even coating of the prepared Interface solution to the ceramic
surface and allow to dwell for 10 seconds. Keep the Interface away from gingiva.
2) Dry the Interface solution thoroughly (approximately 5 seconds) Hold the suction occlusally and blow air away from the gingiva so that the Interface is not blown onto the gingiva. The surface has now been etched and silanated. Place Ortho Solo on the prepared porcelain surface and then place the bonding tray with adhesive per instructions below.
