Overview of the Indirect Bonding Technique
Original
Indirect Bonding Technique – "Sugar Daddy"
The original Indirect Bonding technique used the "sugar
daddy" system to place brackets on the models in the laboratory.
This technique employs a temporary bonding medium, such as caramel
candy, to secure brackets to the model. Once the trays are made
this material is rinsed from the back of the brackets, leaving
the mesh pad exposed for application of bonding adhesive in
the clinical delivery. The most common problem with this technique
is excess flash, the result of too much bonding material being
used.
Although the basic concept remains the same, over the years
several refinements have proven to be very effective in improving
Indirect Bonding. Below we discuss the refinements and improvements
that will make using Indirect Bonding in your practice successful
and consistent.

Custom
Base Refinement and Advantages
A major refinement in the process occurred with the application
of the bonding adhesive to the brackets in the laboratory, and
the term "custom base" technique was coined. Because
the "custom base" technique incorporates the buildup
of composite in the laboratory, a thin layer of adhesive is
all that is required clinically to bond the brackets to the
teeth. This technique is very appealing in terms of hygiene
associated with the final bracket delivery since excess flash
is eliminated. It does however have certain associated issues
due to the precise fit of the custom base pads to the dental
surfaces. Practices must provide impressions and models that
are 100% accurate and make sure the suggested clinical bonding
procedures are well understood and followed precisely. |

Clear
Transfer Trays and Adhesives
The other significant improvement has been the development of
materials used to fabricate the Indirect Bonding transfer trays.
Clear vinyl trays made on a pressure-forming machine such as
the Biostar from Great Lakes Orthodontics have largely replaced
the original silicone tray materials. These trays provide a
clear field of vision and can be easily sectioned to facilitate
clinical delivery. Practices currently using light cured adhesives
will find Indirect Bonding easy to adapt as the clear trays
make possible the use of light cured materials. This is especially
true when using the newer "fast lights" which can
cure the adhesive in as little as 5 seconds. In addition, any
type or brand of brackets can be used with light or auto cure
adhesives and Indirect Bonding. |
