A new device to directly examine parallelism of abutment teeth.
The path of insertion is essential for the successful seating of fixed partial dentures. A new device is described that directly examines the parallelism of the axial walls of the abutment teeth. It can also be used to create guiding planes for abutment teeth of removable partial dentures and determine the path of insertion of a Maryland Bridge fixed partial denture. The various parts of this device, its principle of operation, the results of its use, and advantages in relation to similar devices are presented.
