In conventional bridges, the failure mode is likely to be complete fracture of the abutment tooth with difficult-to-manage sequelae, possibly requiring root canal treatment. With a resin-retained bridge the ...

Adhesive bridges require minimal preparation. Master impressions: An accurate impression should be made of the prepared teeth, along with an impression of the opposing arch ...
