Maryland Bridges

The concern

Single-winged full ceramic resin-bonded bridges, also called Maryland or Rochette bridges, are a good alternative to implants, especially for teenagers. When done properly, these bridges can last just as long as implant-supported restorations or traditional full-coverage bridges. However, using the right materials and correct bonding techniques is crucial for success.

In this case, an attempt was made to replace two missing lateral incisors with adhesive bridges. Unfortunately, the bridges failed after only three months because the wrong design and materials were used (as shown in Figures 1 and 2).

The treatment

To be successful, resin-bonded bridges should always have one wing, be bonded to acid-etched enamel, and the manufacturer’s instructions for adhesive bonding must be followed carefully. In this case, the final bridge was made from strong ceramic (Zirconia, 1200 MPa) and bonded with a special adhesive cement (Panavia V) that includes a primer designed to improve bonding (as seen in Figures 3 and 4).
