Tibial stems are necessary in most total knee revisions to share the load and protect the fixation interface of the tibial tray. Successful use of a tibial stem requires independent stability of the stem with or without cement. Some additional geometry on the undersurface of the tibial tray such as peripheral pegs or fins is necessary to provide additional resistance to rotatory stresses if the...

background: different factors such as impression techniques and materials can affect the passive fi t between the superstructure and implant. the aim of this study was to determine the effect of different impression materials and techniques on the dimensional accuracy of implant defi nitive casts. materials and methods: four internal hex implants (biohorizons ø4 mm) were placed on a metal maxil...

Form document structure analysis is an intrinsic technique. However, It has fundamental problems because interruptions of lines and noise cause low-quality form images. This paper focuses on connecting disappeared comer patterns. Our method has two stages for making correct connections, noise elimination, in which lines whose two end points meet no other lines are eliminated and object line sel...
