InterfaceTM is a revolutionary ceramic primer, which allows the clinician to bond any type of ceramic to a tooth, including the newer high-strength materials. With InterfaceTM, any dental ceramic can repaired safely in the mouth without the use of dangerous hydrofluoric acid. Since it is activated when it is used, the shelf life of the primer is very stable (3 years from the date of manufacture). Best of all, InterfaceTM can be used to bond to ceramic, dentin and enamel ALL AT THE SAME TIME.

Preparation of Interface TM
InterfaceTM is furnished in two bottles, labeled A and B, along with a mixing well and microbrush applicators. To prepare InterfaceTM, a drop of A and a drop of 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. After about 20-30 seconds, the bubble will break down, and at that time the mixture is stirred for 5 seconds with the microbrush applicator. The mixed Interface™ solution must be mixed and used within a few minutes. Once it has become opaque it is no longer useful.

Bonding Ceramic Inlays, Onlays, Crowns and Veneers
It is highly recommended that the ceramic surfaces to be bonded are first lightly sandblasted. The prepared InterfaceTM solution is applied to the ceramic surface in an even coating and is allowed to dwell for 10 seconds. It is then dried for 5 seconds with dried compressed air. One coat of Simplicity® 2 is applied to the primed surface, is air-thinned, dried and light-cured for ten seconds. A second coat of the Simplicity® 2 is applied and dried, but it is not light-cured. The desired resin luting cement is inserted into the restoration and it is seated and finished according to the manufacturer’s instructions. If the preparation has been sealed with Simplicity® as recommended, the following protocol may be employed for the tooth on which the crown or onlay is being placed: clean the prep of the temporary cement. Clean any remaining temporary cement with a microbrush and Simplicity® 1, which will dissolve the remaining cement. Rinse and dry the prep. Apply a coat of Simplicity® 2, dry and light-cure it for ten seconds per surface. Then apply another coat of Simplicity® 2, dry but do not light-cure it. Then place the resin luting material (such as Anchor™) into the crown or onlay and insert.

Repairing of Ceramics
The prepared InterfaceTM solution is applied to the repair site and allowed to dwell for 30 seconds. It is dried with a stream of compressed air for 5 seconds. Three brushfuls of Simplicity® 2, are applied to the primed surface and dried with compressed air for at least 5 seconds. The adhesive is then light-cured for ten seconds, or for the period of time as instructed by the manufacturer. Adhesives having more than one bottle, such as SurpassTM, may also be used for repairs. The primer and bonding resin (e.g. Surpass™ 2 and Surpass™ 3) may be applied in place of the one bottle adhesive. Composite resin is then added and finished according to manufacturer’s instructions.

Repairing Ceramic and Tooth
There are times when tooth structure is exposed by the fracture of a ceramic restoration, such as might occur with a veneer or ceramic crown. The prepared InterfaceTM solution is first applied to the ceramic for ten seconds after which it is dried with dried compressed air for 5 seconds. The solution is then applied to the exposed tooth structure evenly and agitated gently for ten seconds. The solution applied to the tooth structure IS NOT DRIED. Three brushfuls of Simplicity® 2 are applied directly onto the InterfaceTM solution on both the ceramic and the tooth surfaces. The surface is then air-dried thoroughly for at least 5 seconds. Two more brushfuls of the one-bottle adhesive are applied and the surface is air-dried again for five seconds. The resin adhesive is then light-cured for 10 seconds, or as recommended by the manufacturer. (Note: Surpass™ 2 and Surpass™ 3 may also be used for this type of repair). Composite is then added and finished according to manufacturer’s instructions.

Repair of Porcelain-to-metal Crowns
Roughen the surface with a diamond. Lightly sandblast the surfaces to be repaired. Apply the prepared Interface™ solution to both the ceramic and the metal for 10 seconds and then dry the Interface™ solution for 5 seconds. Apply one coat of Simplicity® 2, dry it and light-cure it for ten seconds. Apply the desired composite and complete the repair
