About 2 Sets Dental Implant Trephine Kit 8pcs Set Polished Surgical Surgery
A dental implant trephine is a hollow cutting drill. Its cylindrical crown cuts around a core instead of working through all the material in its path, which makes it a different instrument from a solid drill. The trephines in this listing have hollow, toothed crowns, and they are shown in labelled holders.
The listed sizes
The size labels in this listing run in whole millimeters from 3 to 10: 3, 4, 5, 6, 7, 8, 9 and 10 mm. These are nominal labels. A label does not say whether the figure is the inside diameter or the outside diameter, and it does not give the cutting length or the shank.
Inside diameter, outside diameter and working length
A trephine has two diameters. The inside diameter is the hollow opening, and the outside diameter is the outer cutting envelope. A single number needs a label saying which one it is, so a trephine described by its inside diameter and one described by its outside diameter are not the same size even when the number matches. Cutting length, overall length and shank are separate attributes too, so a size label alone does not tell you how far the drill reaches or which handpiece it fits.
Trephine or solid drill
A solid drill removes the material along its whole path. A hollow trephine cuts a ring and leaves a core in its center. They are not substitutes for each other, and a trephine is also a different instrument from a bone collector, which gathers bone chips. If you are comparing collection instruments, see our bone collector drill set.
Drills and holders are counted separately
A holder is not a drill, and the number of drills in a kit is not the number of holders. When you compare this listing with another trephine set, compare the number of drills, the sizes and the holder separately rather than relying on the pack name.
Matching an existing trephine
To match a trephine you already use, send its reference, its labelled inside and outside diameters, its cutting and overall length and its shank type. A nominal size, or a general word such as short or long, does not identify it. For other trephine, tissue punch and saw configurations, see our implant trephine, tissue punch and saw kits.
