An instrument that acts like a cookie cutter, called a trephine, cuts a precise circular shape. |
|
In 2 cases, a bone marrow trephine biopsy was also available for examination. |
|
Primarily used in the coronal area of the root canal to trephine around posts. |
|
However, should the dowel still be in the iliac crest, remove the trephine attachment and mount the appropriate extraction attachment. |
|
To remove an implant, use a trephine with a greater diameter than the implant and remove the obtained bone cylinder. |
|
Caution: In most cases, the bone dowel will be in the trephine attachment due to the large portion of cortical bone. |
|
Note: Trephine attachment should not come in contact with metal hardware to prevent breakage of trephine. |
|
Perform a neurosurgical trephination with the electric pen drive and trephine burr. |
|
We essentially use a trephine to remove the diseased cornea before attaching the new cornea so that visual acuity is restored. |
|
The trephine is reintroduced up to the cyst, and gradually advanced by hand, to push up the subchondral bone. |
|

|
The trepan was succeeded by the trephine, which employed a cross handle and a centre-pin to stabilize the saw as it first cut a circular groove into the cranium. |

|
A proper squicking requires you to trephine your partner and pork its brain this way. |
|
Mount the appropriate trephine attachment onto the holder. |
|
You must check whether remains of bone are trapped in the trephine drill. |
