Repairing System

Signum metal bond

Signum metal bond is a product developed by Heraeus research: a cold bonding system with up to 300 percent better adhesion of composite and
acrylic material to precious, non-precious metal alloys and titanium. Signum metal bond is a revolutionary development combining maximum security with quick and easy application. Signum metal bond is a useful addition to the Signum system ideal for combination with Signum composite.

Applications:
  • Bonding of metal framework surfaces to composite
  • Bonding of methacrylate acrylics to metal
  • Bonding of root canal posts,
  • Bonding agent for the recreation of composite restorations

Signum zirconia bond

Signum zirconia bond is a bonding agent especially for the successful and promising material zirconium dioxide.
Until now, it was impossible to bond a zirconium dioxide framework to composite, since the material is generally known to be unreactive. Thanks to recently developed technology, Signum zirconia bond is the fi rst to allow durable and secure bonding. The new adhesive achieves high bond values between the framework and veneer, namely between zirconium dioxide and Signum ceramis as well as Signum composite.

Working with zirconium dioxide frameworks: even easier, even more durable


One framework instead of two:
In implants, the long-term provisional restoration (e.g. with Signum composite veneer) can be applied to the same framework as the fi nal ceramic restoration.

Support for placement:
Conditioning the bonding surfaces right in the laboratory or at the dental offi ce ensures secure bonding with composite cements.

Better safe than sorry:
Its high security and durability, even with composite veneers, are invaluable advantages of this product. They are the result of Heraeus Kulzer's research and the tested and mutually compatible bonding system.

The ceramic repair system

Signum ceramic bond 2 Step Bonding agent for Silicate ceramic
Indication
  • Use for Intraoral and extraoral repair at chairside with a direct composite
  • For preparation of the bonding Surface before cementation. e. g. Ceramic restorations using dual cured composite
  • To generate a dispersion layer in order to achieve connection/bond with (Meth-)acrylate based composite (e.g. Signum composite, Signum ceramis, Venus and others)

Advantages
  • Quick safe and secure handling
  • Intraoral and extraoral application
  • No need for pre-polymerisation
  • Extraordinary bonding strength and durability ( 30 MPa according to ISO 10477)
