Contax is a light-curing, self-etching, and self-conditioning adhesive system that ensures a high level of protection from sensitivities – deliberately in two treatment steps.

A preliminary etching step is not required since this is done by the carboxylic acid contained in the Primer. Primer and Bond are separate components and can thus optimally fulfill their respective functions. The excellent resultant bonding properties are markedly superior to one-component adhesives. Thanks to the integrated etching step and the water-based Primer, the system is very tolerant regarding the applied technique and prevents postoperative sensitivities in the patient. You couldn’t be any more careful with your patient’s health.

Advantages:

• No additional etching with phosphoric acid

• Priming and bonding are effected in only two steps

• Secure long-term adhesion because of separate priming step

• Reliable depth of demineralization

• Very technique tolerant

• No postoperative sensitivities

• Compatible with all commercially available materials

Technique tolerance

Contax-Primer is self-etching and self-conditioning on enamel and dentine. Since over-etching is not possible, a reliable bond can be ensured at all times.

Because of its water-based and easy-to-use Primer, Contax is very tolerant regarding the applied technique compared to other systems and does not cause over-drying.

With the special pre-treatment the sensitive collagen fiber network is optimally prepared for the bonding agent. The smear layer is dissolved and modified, thus enabling reproducible and reliable adhesion results and an almost certain prevention of postoperative sensitivities.

Secure long-term adhesion

Contax-Bond penetrates the prepared hard tissue and forms a so-called »hybrid layer«. With this layer, a solid adhesion with the subsequently applied restorative is achieved, ensuring a reliable and lasting bond.

Flexibility

Thanks to the Activator, Contax can adapt to the curing mode of the respective filling material and can thus be used in combination with light-curing and, by adding the Activator, also with self-curing and dual-curing restoratives. The Activator is only necessary when the material used is not light-cured.

The mixture consisting of a drop each of Activator and Bond is worked into the cavity.The addition of the Contax-Activator ensures a solid adhesion in the boundary layer between the self-curing or dual-curing material and the Bond. Even when used with the Activator, Contax must be light-cured at all times; however, due to its formula, cooling is not required. Contax can be stored at room temperature.

With Contax, practitioners attain excellent and reproducible bonds from the very first application.

Compatibility

Contax is compatible with all commercially available materials. It is well-suited for use in combination with light-curing filling materials, especially the DMG products EcuSphere and Vitique. Used with the Activator, Contax also makes a perfect bonding agent with self-curing and dual-curing materials such as LuxaCore Z-Dual, Vitique (dual-curing variant), and PermaCem-Dual for permanent treatments.

Ratings from independent test institutes

Independent studies confirm the very good adhesion of Contax on enamel and dentine. Excellent bonds can be obtained with this product regardless of the type of method applied: Contax is consistently among the top rated products of all tested materials and thus provides assurance for the user, achieving a secure and reliable bond. Numerous studies, such as those conducted by the independent US publications »Reality« and »The Dental Advisor«, also confirm the excellent bond strength of more than 20 MPa on enamel and dentine. The Dental Advisor: »Lack of post-operative sensitivity was reported as very good.«
