Teeth Bonding Procedures


Conventional restorations (fillings, crowns, and bridges) used to require the removal of a substantial amount of tooth structure to make them strong and to give them sufficient mechanical retention to the tooth.

Throughout the last three decades different bonding agents have been developed that allow a direct adhesion of restorative materials to the tooth surface. The most recent generations of these agents finally provide high bonding strengths. This allows the secure placement of restorations without extensive reduction of the tooth for mechanical retention. Bonded restorations also withstand higher pressure and tension without breaking. All this allows to save a great amount of tooth structure. It is evident that this development does not just benefit cosmetic dentistry and smile design.

Teeth that are restored with bonded restorations have recently been shown to be more fracture resistant than healthy and intact teeth.

Once your tooth is ready and clean to receive a restoration, it will have to be conditioned to allow the bonding of the restorative material to take place. To understand the value of bonding, a few elementary things about tooth structure have to be understood. If you like to go into detail please go to the Tech Specs page and learn everything you have to know to fully understand this subject.

The application of an etchant (blue) creates  a penetrable collagen-fibril network, which allows the diffusion of hydrophilic resins into the outer tooth structure. Note the protective rubberdam, the retraction clamp, and the matrix band. The placement of these devices ensures a clean and optimized environment for the bonding procedure and protects oral cavity and throat from debris and chemicals.

The application of a hydrophilic methacrylate monomer (primer) facilitates the bonding of the filling material to the tooth. The primer creates a hybrid layer in the surface dentin that protects the tooth to acid attacks (as produced by lactic-acid releasing bacteria that cause decay).
