ABSTRACT The evaluation of the relative parallelism of two or more abutment preparations for fixed partial dentures with the help of a mouth or photographic mirror may encounter the errors. A dental periscope is a new device for examining the abutment preparations outside the mouth, which is otherwise difficult to judge intraorally. With the help of this device, the evaluation of relative parallelism of tooth or implant abutment preparations for fixed partial dentures will become more convenient. Axial preparations for individual inlay, onlay or crown also can be evaluated easily with this device.
