Longevity of anterior resin bonded bridges: Survival rates of two tooth preparation designs

Abuzar M, Locke J, Burt G, Clausen G, Escobar K. doi: 10.1111/adj.12612

Introduction

A resin bonded bridge (RBB) represents a conservative option for replacing a missing tooth where a fixed replacement is desired. Such bridges may have several advantages when compared with conventional full preparation bridges or implants. Due to perceptions relating to their tendency to de-bond over time, their widespread use has often been restricted.

By definition, resin bonded bridges are retained in place by adherence to tooth structure with a resin cement. Preparation of the tooth structure may also be completed in the form of grooves or other features for localisation and retention. Careful case selection is important for RBBs and can include considerations such as the health of the abutment tooth, the available enamel for bonding and the occlusion.

This study investigated the survival of anterior resin bonded bridges placed between 1990 and 2012. Two different preparation designs were assessed, as well as the demographics of the study population.
