The Roch Bridge (Rochette Bridge) is a specific type of adhesive bridge used for single-tooth replacement. It is distinguished by its perforated wing design, which is prepared only on the lingual or palatal (inner) surfaces of the supporting teeth.

At our laboratory in Florya, Istanbul, we manufacture these restorations with high precision, prioritizing the preservation of natural tooth structure. Our solutions are produced with both metal frameworks and digitally fabricated PMMA materials.

What Is the Roch Bridge System?

Considered the predecessor of Maryland bridges, the Roch Bridge design is based on a mechanical locking principle. The funnel-shaped perforations on the metal wings allow composite resin cement to flow through these openings during cementation, creating a physical lock.

Advantages of Roch Bridge Restorations

Conservative Approach: It does not require full crown preparation of adjacent teeth. Minimal enamel reduction preserves the natural tooth structure.

Mechanical Retention: Perforations on the wings enable the adhesive cement to lock physically, reducing the risk of debonding.

Temporary and Semi-Permanent Use: It is an ideal interim solution, especially during implant healing or for younger patients until definitive treatment is completed.

Fast Application: With a digital laboratory workflow, restorations can be produced quickly and allow an easy clinical procedure for the dentist.

Reversible Treatment: Since the supporting teeth are minimally prepared, they remain suitable for future implant or alternative prosthetic treatments.

Our Laboratory Production Workflow

The success of Roch Bridges depends on micron-level adaptation and precise positioning of the perforations:

Precise Data Analysis: Digital or conventional impressions received from the clinician are evaluated together with occlusal relationships.

CAD/CAM Design: Computer-aided design optimizes wing thickness and perforation positioning without interfering with the patient’s occlusion.

Material Selection: Depending on the clinical indication, cobalt-chromium (Co-Cr) alloys or high-strength PMMA blocks are selected for long-term provisional use.

Surface Treatment: Special sandblasting procedures are applied to the internal surfaces of the wings to enhance retention.

Indications

Roch Bridge solutions are commonly preferred in the following situations:

• Single-tooth replacement in both anterior and posterior regions as a temporary or semi-fixed option.

• Maintaining esthetics during the osseointegration period after implant surgery.

• Splinting cases where periodontal support is required.

• When an economical and conservative bridge alternative is needed.
