BONDINGS

      

In the past, chipping a tooth meant replacing it with a crown, unless the chip was small enough to be treated with cosmetic contouring. With bonding, however, the process of repairing broken teeth has been revolutionised. Now, a new tooth can be formed simply by applying mouldable resin composite to its remaining structure. This rebuilds the tooth to its original shape.

Bonding or chair-side hand-carved veneers is an ideal solution to many dental problems.

• Closing small spaces.
• Covering stains.
• Repairing small fractures.
• Treating sensitive teeth.
• Lightening tooth shade.

The bonding process can be carried out in the one visit and often without the need for local anaesthetic and in conjunction with the Air Abrasion System A shade of composite resin restorative material is chosen to match the existing tooth, which is then treated and cleaned with a special chemical. Layers of liquid bond are placed between the tooth and the composite resin. The composite resin is then shaped cured (set) and polished.

 

The beauty of bonding is that there is little or no reduction of the tooth structure, the procedure is reversible and the tooth shade can be lightened. However the bonded restorations can chip or stain more easily than their laboratory-constructed counterparts but can be repaired or replaced more easily.

The bonding technique is also used when placing white `tooth coloured’ restorations in both the front and back teeth
