The natural plain thread is precision ground in order to achieve a monofilament character and treated with a glycerol containing solution. Plain is absorbed by enzymatic degradation. Adsorbable biological suture material. Chromic is an adsorbable suture made by twisting together strands of purified collagen taken from bovine intestines.
The 2nd-century Roman physician Galen described sutures made of surgical gut or catgut. [27] In the 10th century, the catgut suture along with the surgery needle were used in operations by Abulcasis. [28] [29] The gut suture was similar to that of strings for violins, guitars, and tennis racquets and it involved harvesting sheep or cow ...
Catgut Chrome (B Braun) suture is a variant treated with chromic acid salts. This treatment produces roughly twice the stitch-holding time of plain catgut, but greater tissue inflammation occurs. Full tensile strength is extended to 18–21 days. It is brown rather than straw-colored, and has improved smoothness due to the dry presentation of ...
Catgut (also known as gut) is a type of cord [1] that is prepared from the natural fiber found in the walls of animal intestines. [2] Catgut makers usually use sheep or goat intestines, but occasionally use the intestines of cattle , [ 3 ] hogs , horses , mules , or donkeys . [ 4 ]

Chromic gut suture-make from the goat or cow;s intestine. These sutures are absorb within 7-14 days, it had the fast absortion rate compare to synthetic which will absorb within 42-56 depending on the range of product. As different range of product the absorbtion rate varies.
Expansion forces at the sutures lead to expansion of bone and thus growth of craniofacial skeleton. Cranial vault increases in size via the primary growth of bone that happens at the suture. Sicher theorized that tissues such as periosteum , Cartilage and sutures are growth centers just like epiphysis of the long bone that allow the bone to form.
In structural geology, a suture is a joining along a major fault zone, of separate terranes, tectonic units that have different plate tectonic, metamorphic and paleogeographic histories. The suture is often represented on the surface by an orogen or mountain range.
